First Alert by Resideo Positive Reviews
SolidWe just swapped out our home smoke detectors. We had to migrate to First Alert from Nest Protect due to Google ending the product. The App is super simple to follow during device setup process. It’s nearly bulletproof—unless there is an interruption in the setup process (like a network problem or a taking a phone call during the process). If you take too long, the device will register on the company’s database but it will not allow setup in the App. A 25 minute phone call to First Alert, proving ownership and sharing the device’s MAC, solved that setup issue. The App is straightforward to use—all devices appear on the dashboard. We did have a defective unit that decided to sound off in the middle of the night. Because all devices are on interconnect, all the alarms went off. It was VERY difficult to stop the false alarm from the App. We tried to silence the bad unit and finally had to grab the ladder and physically remove the device (and yank out the battery pack). I didn’t remove a star from the rating because I do not know if it was an App problem or a Network problem..KB BankerVersion: 2.24.2
App update doesn’t work properly.You should make it clear that customers must call customer service to delete the units from the old App. Otherwise, you can NOT add the existing units to the new App. Also, the change password function on this new App doesn’t work. I never received a link to change my password. You must test all functionality of new Apps prior to launch. This has NOT been a good UX. I expect better from Honeywell..MacPotusVersion: 2.24.2
Smoke detectorsWiFi is poor on the units when I first the the unit got 2 and try to set up the WiFi on them gave me some trouble and both of the smoke detectors getting to the part of putting my router password on the app would not get connected have to try at least 5 times before it worked on both unit. I have the best router wife that money can buy the unit are not even that far for the router I have ring cameras a lot further and they work great but that’s not the big problem anytime the WiFi goes down because Comcast is working down the street and the internet comes back all my devices come back on line from nest ring hue Alexa lights my old 2 nest smoke detector but the new first alert smoke detector hardwire don’t I have to manually reset the WiFi on the units and go through the process all over to get them back online I think the unit have a poor WiFi signal on them.AasmiamiVersion: 2.21.8
Uncoordinated ChangeoverI have used the Resideo app religiously for years and have been thrilled with the ability to control my thermostats with my phone. It’s a very handy feature when I’m not able to physically get up to change the temperature.
Yet, this past week I suddenly could not log into the Resideo app anymore.
Each time I tried to recover my account the Resideo app indicates the account does not exist.
When I tried to create a new account I was forced to Resideo’s new app “First Alert by Resideo”.
The problem? I cannot connect my thermostat to the new app because the app indicates the thermostat is already connected to an app (i.e. “Resideo”). If I want to connect to “First Alert by Resideo”, then I first need to disconnect from “Resideo”.
How can I do that when I’ve been booted out of the Resideo app?
I’ve even gone so far as to factory reset my thermostats, but I still cannot get them to connect to “First Alert by Resideo” because they (somehow) are still connected to the Resideo app even after a factory reset.
Now I have to call customer support to try to re-establish the ability to control my thermostats with my app. Seems simple enough, but this is a much larger headache than I would’ve expected for the price I paid for the thermostats..Just_Peachy!Version: 2.24.2
Face IDWhy does Face ID only work once in a while. I cannot find a way to set it to work every time. Latest update seems to have fixed the Face ID issue. But now it is NOT finding my thermostat. Added once and told me it was already registered. It did finally show up, TWICE. I removed one device and both were gone. Added it again today and it is not there again.
Latest update to this very frustrating app. Added the thermostat again. It now shows twice but only if you pull down to update..Caesars fanVersion: 2.7.3
Released too earlyEvery other smart home app (google home, alexa, etc.) only is able to work with the Honeywell Home app. There is no option to link with the new First Alert app. For new users this means you are stuck with this app until they decide to integrate it with other apps. Please fix this.
Edit: at least the support is good. hopefully this is more straightforward OR better documentation online or in the physical manual per device.Mcch1nVersion: 2.24.3
Won’t stay signed in.When it works, it works great. However, it keeps signing me out, and it is a real pain in the rear to sign back in because I have to go through all the resideo advertising. It signs me out at least once a day and the day before yesterday it signed me out three times. I can’t say for sure, but it may be when I leave my home Wi-Fi that it signs me out. this could be very aggravating because what does the cell phone do for you. if you can’t carry it around with you wherever you go.GrisgrasVersion: 2.21.8
Used with Honeywell ThermostatThe app installed fine on my iPhone. I was able to connect to my new thermostat and the WiFi router. Seems to work fine. My only issue is that I can’t see the current status of the thermostat on the app. For example, if the device is calling for heat that information is displayed on the thermostat but not the app. Other than that everything seems fine..RayJ0727Version: 2.23.0
Thermostat won’t stop runningHey there, I love my new thermostat, but for some reason when I tell Alexa to turn it off, it tells me it turns it off, but it keeps turning off and on it won’t go to off it just stays in the last mode, even though it says it is off. I’ve tried to check all the settings, but maybe I am missing one, if anybody has had any experience with this, let me know. An example is when it is on heat and I tell my Alexa to turn it off she tells me she sets it off, but then it keeps going turn off and on and off and on..Jill's BellaVersion: 2.24.2
Pairing & Humidity issuesTried everything with tech support multiple times before determining only one pairing allowed per day. It's a fact. My home has 9 zones, and with the troubleshooting it took 2-weeks to get the app set-up.
Also, I have figured out humidity levels don't work. Seemed like a great feature until I realized the remote sensors aren't equipped for this. Would be better if the default display was 0 if no input is detected.
Despite these issues I do like the app..Maddening serviceVersion: 2.24.2
Will not connect to AlexaAlexa goes to you old app and will not let me sign in to link Alexa.
UPDATE:
I figure out how to get mine to work with Alexa. Menu and scroll down to Integrations. Select Alexa and you will go through the process setting up your Alexa. It works. It would have been nice if they gave you this option when you first try setting up your Alex. Google is also listed here.AmmojrmVersion: 2.24.2
GlitchyTwo of my units are listed as "Offline" in the First Alert app. The Google home app shows all of them active and receiving updates frequently. They went offline when AC power was applied during installation. I'm not doing a factory reset and going through the initialization again just so they work in this app. It's probably some strange naming problem related to using the same names for the new devices in this program (carried over from Nest), and then linking them to Google home?.SLO BobnVersion: 2.24.2
ChangeAppears to have changed from the Resideo app to this First Alert app…kicked me out of the Resideo app with no notice…my thermostat temps were all over the place. I can’t connect to the First Alert app without being asked stupid questions! Fix the app the way the Resideo app worked!!! Nobody wants to call customer support! We want it to work from the app…what are y’all doing?!.SheKnows32Version: 2.21.8
Graph, battery status worseIn the change to First Alert, two things were made worse: the battery charge is now a couple of extra taps away, and the graphs are from the start of the current week and month so near the beginning just a day or two. They should initially cover one week/month back from today (although I don’t know if week is useful, it could be dropped IMO)..BlmatthewsVersion: 2.24.3
FIXED: Can’t find a way to change unitsI was finally able to change the units by changing the units in my phone’s settings.
Still would have been great if there was a way to change it in the app!
I’m giving it 5 stars because of the excellent customer service experience that I had with Mark. He kept me updated on this matter while finally coming up with the solution to update it in my phone’s settings.
Original review below:
—————————————-
I’ve been trying to find a way to change temperature units from C to F, but looks like there is no way to do that. Can’t find that option anywhere in the app..Chatur ChanakyaVersion: 2.0.15
First Alert Smart Alarm FunctionalityOnly got this app to support my SC5 smoke & CO alarm. It seems to be working great! I have a hardwired smoke detector system with existing SMI100-AC units. Removed one and replaced it with the SC5. Now I receive a mobile notification if any alarm goes off since they are hardwired. Gives me good peace of mind when my dogs are home alone..AnAngryWhiteKidVersion: 2.20.9
Help is not helpfulHelp and Support only has videos- not particularly helpful for deaf people or those who prefer to read information. For additional help, chat is offered and once one enters name, email, phone we are told it's after hours and you can only chat during business hours. Perhaps they should not have the 'chat here' bubble pop up when chat is not really available.H@tFla$hEVersion: 2.24.3
Whoever created this app, thank youThis app has been the most user-friendly, easy to use. I love the fact I can control my thermostat either from sitting in my living room or at work. And it tells me if it’s off-line and it tells me how to get it back online..Sam-EvansVersion: 2.24.3
Filter change reminders brokenFurnace filter change reminders have never worked for me. I set it every month, but it is always disabled when I go in to check why it didn’t notify me.
Overall the app has been getting much better than when I first switched from the old app..Kris2555Version: 2.24.3
Alexa compatibility?I’m revising my rating from 1 to 5. It turns out that the app is, in fact, compatible with Alexa after all. I appreciate the answer from tech support. It’s a great feature to control the thermostat with Alexa in addition to all the other remote features..Davidb2020Version: 2.24.2
MehThis app is convenient, but it goes down with system-wide issues far too often.
I have 2 HVAC systems in my house and wish I could schedule on off and temperature settings, like lighting apps such as tapo and alexa. Instead the app asks confusing questions about what time you get up or go to sleep. I would rather heat my living spaces on one schedule, and bedrooms on another schedule. I don't like this app..AbbraciaVersion: 2.24.1
An efficient way to monitor the thermostatAdded the app and downloaded the pink from the thermostat. Self-guided instructions to link the two. It's important to know the kind of thermostat you have.
I like it because you can customize it to your specifications..Purethinker2116Version: 2.24.3
Equipment StatusApp works fine for seeing and adjusting temperature setting, but why doesn’t it display equipment status? It should show me if the furnace is running, what stage is running, and if humidification or just the fan is running, for instance. I can set a temp but can’t see if the furnace is doing what the thermostat asks. Other brands apps do this..JcavalieVersion: 2.23.2
InconsistentNot sure if the problem with the app, thermostat or the dual system. The thermostat downstairs does not stop as long as the upstairs is running. Until, the problem is resolved, I will give a 3 star rating for now. Hopefully, the HVAC company will solve the issue..GranDonDgoVersion: 2.24.2
App Stopped WorkingEver since newest update, I can’t access the app. Just sits at the load screen. I’ve deleted and reinstalled the app and also restarted my phone. Any advice??
EDIT - Prior to being contacted my the developer it eventually got fixed. Updating to add an additional star!.Whitebare7Version: 2.23.2
Not as easy as pieMake sure you have the MAC address written down, especially if you have another thermostat of the same kind it may recognize the first one instead of the second. Eventually, I was able to set up the second thermostat it may have just taken a while To recognize the new one..Desert Rat - krVersion: 2.22.100
Terrible for trackingThe app should offer more data for tracking. The app only offers one trend: runtime. For someone who is tracking a remote country home, it would be nice to be able to have trends on set point and actual temperature.
The default alerts are also incredibly confusing. The language is so poorly written: « The thermostat is above your specified temperature range of 0 deg »…this implies my high temp alert is set to 0 deg. Or are they implying the delta with my limit is 0 deg?! Who knows.Oli_the_engVersion: 2.24.2
App only reads in Fahrenheit.I’m not sure why but my app (not the physical thermostat) switched to Fahrenheit for some reason, I assume an update, and I cannot not figure out how to switch it back to Celsius. I can switch between both within the app settings and it changes on my thermostat but not within the app itself. My address in is Canada (metric) so I don’t why it seems to think I want Fahrenheit. It wasn’t like this a few weeks ago when I originally set it up and don’t know when it changed. I cannot figure out within the app how to change it. One would assume that if you’d like your thermostat in Celsius you would also like your app in Celsius. Maybe this is a glitch and something with a recent update is causing the app to not display Celsius even when you have it chosen within the settings?
Otherwise I’ve had no other issues with the app and am pretty happy with it, except the name makes no sense…. First Alert for a thermostat? Sounds like a house alarm app..Ultramagnus84Version: 2.19.5

First Alert by Resideo Negative Reviews
Way Too Complicated to Setup Thermostat, Doesn’t Work CorrectlyI didn’t have a choice in using this app to connect the Honeywell T6 in my new build. I didn’t think their apps could get any worse than the TCC app we used at the old house on an older model with fewer bells and whistles, but this one is worse. Setup was TERRIBLE - you get asked ~20 questions about your heating system that no homeowner knows - I had my system’s manual in front of me and couldn’t answer the questions at all! - and there’s no option to skip them. I’m not even sure what most of them are asking!!! From a UX standpoint, the app gives incorrect information about how to connect to HomeKit, telling me to use a menu item that doesn’t exist on my thermostat (haven’t figured that one out yet) and it keeps bringing the enable notifications dialog modal up to go to my settings 2-3x every minute or so which I have already said “Don’t Allow”. While this looks like a native modal, the poor grammar suggests that it’s something the app designed and is using native app commands to push. Super annoying! So I can manually see and control my thermostat from the other room now; the rest of the app is terrible and it hasn’t solved my problems at all. Honeywell - you need to realize that poor UX is a huge reason why people flock to Nest instead of you. We will be replacing this unit with one in the next few weeks because of the terrible experiences..CentrefrenchieVersion: 2.0.11
Terrible appThis app constantly logs you out and uses a splash screen to log you back in with no option to remember your log in info. I bet in the 6 months I’ve been using the app it has logged me about 20-30 times and I am not exaggerating. The app cycle reporting is not helpful at all. Setting a schedule is not intuitive at all and requires you to delete the schedule if you need to make a minor tweek. It would be helpful to have an on demand heat button that was customizable
To raise the heat say, 2 or 3 degrees or run for 30 mins exc without pausing the schedule to the next interval. For example, you wake up in the middle of the night and your cold press the on-demand heat button for 30 minutes and go back to sleep without worrying about it keeping a constant temperature all night long which would require the furnace to cycle on and off..ActiveWVVersion: 2.11.0
App needs work. Do you even test this?Room sensors constantly revert back to turning on motion sensing even after I turned them off multiple times. The outdoor sensor doesn’t show in the app anywhere. Have to look at the Tstat. Really stupid design. Also, you can’t see the equipment status. All of the stuff that’s available on the thermostat. Should be available in the app! That should show up on the main page of the thermostat. Can’t see when equipment is running. Should say cooking on, ventilating on, dehumidifier on, etc
Major issue is that dew point lockout for ventilation is too high! 65 for a minimum is too much. Please add 60,55 and 50. There should not be a limit. Let us decide not you! 65 is way too high
Please fix these problems instead of trying to cram every product in existence into one app.Nunyabizness!Version: 2.24.3
Unnecessary and buggyTotally a case of a supplier creating an app to force an invasive relationship with its consumers. Beyond initial set up of devices, it provides zero value. There’s absolutely no reason their products should not be able to integrate directly with HomeKit or Google Home.
Like many, I’m here because the excellent Nest Protect smoke detectors are reaching end of life. And First Alert provides the “replacement.” Unfortunately, users are saddled with a buggy app that is only good for setting up integrations with other services. The app itself appears incapable of remaining linked with the devices it’s supposed to manage. (No, no, you dumb app, I’m not resetting my three new devices again.) And it is absolutely catastrophic on maintaining Wi-Fi connections. Junk..DerschlumpwitzkowskiVersion: 2.22.100
Homekit user? Don’t buy Honeywell.I’ve been using a Honeywell T5 WiFi thermostat for years. Once registered with Resideo, I prohibited it from accessing the internet, shutting down that unknown possible hacker intrusion. It crashed periodically, and had to be reset, but all was well, controlled by automations. ALL GOOD THINGS COME TO AN END. Replaced my furnace with a new high efficiency Lennox unit. Installer insisted that the thermostat needed internet to access the current outside temp. BS! It didn’t. But, while connected, Resideo installed new firmware. Disable internet = no homekit access. Fail to register you thermostat? Homekit access cut off. You can put it on snooze, but how long is the snooze? I assume they will make it painful enough that you relent to their snooping, or throw away their thermostat..NotGoneFishingVersion: 2.24.3
Annoying and no dark mode.I only have one device (thermostat), but it wants to show me options for all other kids of devices. It should let me default to the thermostat page. Plus it bugs me with offers and no setting to turn them off.
Honeywell makes you use this app for their thermostat. They’ve been around long enough, they cooks easily pay to have a slick, usable app developed instead.
NO DARK MODE. A home automation app is most valuable in the middle of the night when I don’t want to get up to change the temperature. But now I have to blind myself first with a loading screen that is all white except for a small red icon in the middle. And then the loaded app is still 70% pure white..Mars VikingVersion: 2.22.100
HVAC runtime data won’t showThe lag is publishing HVAC runtime in the app is comical. There is a note that says data may take 48 hours to publish (why does it take so long?) but my experience lately has been far worse which leads me to think there’s a bug. Today is 1/6/25 and in week view, I’m not showing any runtime data since 12/22. If I look at month view, all of December is shown but nothing for January. It’d also be helpful to see more detailed view of runtime data (such as time of each on/off cycle) because XX hours XX minutes isn’t that insightful. My old Nest was capable of that and I looked at it often to see cycle times..ZelinomanVersion: 2.11.0
UnfortunateI got this app to use my first alert smoke and carbon monoxide detector after my google one expired. I wanted it to be a good replacement, it's not. I'm stuck with a $130 alarm that I can't control from my phone, it sounds awful compared to the google one I had before, and I'm overall really disappointed. I was able to press the silence alarm once from my phone when I first plugged it in and it went off with an incense stick but it hasn't worked since. This alarm goes off when steam from the shower leaves the bathroom. It says finding sensors but it never does. I've had the most difficult time trying to connect with any support for the app and device..MonsterDixVersion: 2.22.100
Total junkwareI received an invite to join a friend and family user group in order to control the thermostat in a shared home. HUGE problem with this app: first of all, the invitation link in the invite email sent by the primary user does not jump correctly to the app let alone even point at joining the family group: it’s a link to the appstore page itself! There actually isn’t any family group function! The second: the app can’t register multiple users to the same thermostat even if you’re able to physically attend to the thermostat and attempt to link to your device. Junkware!.Meowster444Version: 2.24.2
Not a good app for ThermostatsThis came up as my only option when I purchased my Honeywell Thermostat. I installed the Resideo app, tried to log in and was trapped to this thing. It would be better if I could actually put in and adjust a schedule. Then to get the Resideo app to work I had to create a login on the webpage, which tried to get me to purchase another Thermostat. Honeywell if you don’t fix this then I will rip out all three of my Honeywell thermostats and put something else in its place. Not kidding..Bad app127Version: 2.24.3
Will NOT Stay Connected with iPhoneI love the idea of being able to control my AC & heating from my iPhone. But this app has some real issues with connectivity. It constantly (at least once per day to every other day disconnects. It’s a pain in the backside to go through the process of resetting my network, uninstalling and reinstalling the app, or most often, deleting my thermostat and adding it back to the app. When the app works it’s great! But it only works 10% of the time..XPrepperVersion: 2.23.2
Celsius to farenheitWhere do we switch from C to f on the app?? I’ve been looking everywhere and cannot find the switch. It’s driving me nuts! Please help
Follow up: I finally figured it out, if you iPhone is by default in Celsius it will show Celsius. There is no toggle switch within the app, which is terrible design. So to fix it, go to settings and at the top search « temperature » and the first option will show you what’s the iPhone preferred unit for temp, and you can switch to wherever you want.
The developers need to put a switch in the app, in the settings section..Julien10489Version: 2.11.0
Useless!!!!!This app has got to be the absolute worst there is for any sort of smart home device control. I have the X2S device and this stupid app cannot find the device when it’s flashing the Bluetooth on the correct screen and everything. When it did find it, it would keep going offline and then online again all the time. Please can we get a better developer to fix the issues with this app because clearly they do not have any sort of degrees or certifications in this line of work..DJones0421Version: 2.21.8
Access ability nightmareI am completely blind and use VoiceOver on iPhone. This app contains unlabeled buttons and navigation issues that make it difficult to use independently. Important thermostat functions are not fully accessible, and I often need sighted assistance to understand controls and settings. A thermostat is an essential home device, and blind users should be able to manage it independently. I hope the developers improve VoiceOver support, accessibility labels, and navigation throughout the app..Nelson 3798 Version: 2.24.3
Where’s the widget? & BooooI’m so tired of all the smart appliances having different apps, so I’m trying to at least get it set up so that I can monitor everything in one place by using widgets. Why is First Alert the only smart appliance app with no widgets?
Updating - App is terrible. Including no widget, it randomly won’t track runtime, which is a key feature for a supposedly smart thermostat. I’ve hunted for an hour and can’t find any troubleshooting support.
I won’t be buying the SC5 smoke detectors I had planned throughout the house..Snow-ravenVersion: 2.24.2
UselessJust got a new thermostat and have to use this app. Well it won’t allow me to sign in. Press sign in and the screen flashes then goes no where. Thought they mentioned fixing log in issues on latest update. Well guess what ….useless. Now i can’t remote access my thermostat.
Oh and although it’s downloaded on phone the app icon is no where to be found! I can search and access that way but it’s playing hide and seek and I don’t have time for that.
Hope the developers prioritize this!!!.Archi-momVersion: 2.21.7
Terrible app…when it worksI barely review apps. I’d sooner just delete them and forget about it but this one is the only way to control my thermostat in my home. Setup process is full blown ret**ded followed by a useless UI and not to mention the fact that if you want use it to actually adjust the AC temp (all it needs to do) you need to throw out 10 Hail Marys and 3 our fathers and even then it doesn’t work. Post reply from developer : I called and it’s still garbage. Can’t change that. Nice try though.TimlogcabinoVersion: 2.17.3
Hard to UseMy prior thermostat had a great app. Easy screen to look at and easy to change the schedule. This is the opposite. Open it to useless information. Spend 15 minutes trying to find the schedule so you can change a time or temperature. Very ugly to look at. Must have had minimal budget to work from. Wouldn’t have bought this thermostat knowing this would be the app that controls it..Cruzr800Version: 2.22.15
SC5 Smoke and CO AlarmI thought I was being all techie when I bought my new condo and replaced all 5 smoke detectors with the First Alert SC5. Big mistake. Four out of 5 have had issues with false alarms that won’t clear or mysterious device faults. The app has a persistently greyed out silence alarm button. What’s the point then? Links to support within the app go to Resideo’s site which doesn’t provide SC5 support. Seriously considering writing off this $650 expense and getting something from their competitors.JustJack75Version: 2.24.3
Absolutely uselessEvery other day it’s new connectivity issues between the thermostat and this useless broken app. Everything is telling me it’s connect but the device doesn’t show on my dashboard. When it does show my device it says it’s syncing, it’s been “syncing” for 8 hours with no change. Useless tech support too as they’re virtually impossible to reach unless you plan on taking a day off just to chat with their 9-5 chat bot..HoneyBSpitVersion: 2.24.3
BuggyI cannot modify the preset schedule, it just throws an error after spinning for 30 seconds.
If I make a new schedule, it doesn’t save accurately. And then it cannot be modified after the fact. Thus, the scheduling feature is worthless.
I managed to enter in my preferred schedule manually into the thermostat, which is following the schedule. However, the app doesn’t reflect this. I cannot imagine the bugginess if both the app and thermostat disagreed on a temperature..AstrumVoxVersion: 2.24.3
Prior Nest UserI gave this 1 star because I had to, but I really would give it a zero!! Resideo First Alert is a very sub-par app and service is horrible!!! Only using it a few weeks, servers have been down for days, terrible communication of outages and the customer service reps at the 1-800 number have no idea what’s going on. Data doesn’t update timely… I have no idea if the heater is running for a seasonal home…. Just a terrible app, with such advanced technology out there!!! DO BETTER HONEYWELL!!!!!!.Sbabs2021Version: 2.24.0
Really dumb about basicsThe app is frustrating to install multiple devices. FFS, once I’ve installed a smoke detector, remember the WiFi settings for the next one. Better yet, remember that I already clicked through the disclaimers and notices about how alerts work and how calling 911 from a foreign country might involve roaming charges or just plain not work. I mean really… all that hassle for every single unit?.Owen DeLongVersion: 2.24.3
Horrible! Do not use this App.Unless you are forced to use this app, stay away! Adding devices is not easy. Took numerous tries before finally connecting. Doesn’t update changes like the name of your device. App is slow when opening and doesn’t have all the features of Resideo -Smart home like connected services. I’ve been using Resideo - smart home for a couple years and that app is great. Stick with the old app as long as you can..Pa281612001Version: 2.19.5

No support!!This app won’t sync to my thermostat and says to contact customer support however the link takes you to a non existent page/broken link and the same thing happens on the website. Incredibly frustrating that all these apps that are supposed to make your life “easier” are just sources of frustration and don’t work correctly.
