User Reviews
Honeywell thermostat users just got kicked out of the network with this horrible launch of the first alert app. You can no longer use Alexa to control your device. Your builder model isn’t supported. This is a screw the customer money grab. If you want your device to work again, you have to buy the new model. I will never buy another Honeywell or TCC or anything with the name residio attached to it. They are the worst.
No connection useless
Why do I have to create two accounts, one for Smart home app and one for First Alert??? And why do I have to add my address to work in mu freaking termostat??
Have had four units for about six months. Averaging about one false alarm per month. I took one unit out of service, might do it for another.
Kept asking me to removed device when device was not present. Gave up and will go buy a different brand now.
The detector goes offline about every other week. It reconnects a day or two later. I never had this problem with Nest.
We have had dozens of false alarms sense we had to replace our expired nest sensors. These are trash. Stay away.
Nothing but problems. Aways an issue. Disconnects constantly. Developers need help clearly.
Installed and created account. During email confirmation, the link navigates to download First Alert page but the app is already downloaded.
I have purchased two Honeywell WiFi thermostat and have connection issues with the app on both resulting in the inability to control them remotely. Completely defeats the purpose of a WiFi remote. App help center was no help in resolving the issue.
Shuts off mid registration and then states devices already registered and will not allow connection to WiFi. Tells you to delete device but device not available
What a wonderful service! The whole crew came right on time. Respectful to our home, pet and a baby and so polite. Thank you so much for your service.
