The app is visually appealing and logically organized, but there is a major flaw. When returning to the app, it doesn’t reflect current settings of the thermostat unless the app is terminated and then relaunched. For example: yesterday I changed the set temperature from 70 to 72 in the morning and when submitted, the app showed a set temperature of 72 and Hold until 3:45 PM. This is all correct. When I went back into the app today, instead of showing a set temperature of 70 and FOLLOWING SCHEDULE is still shows a set temperature of 72 and Hold until 3:45 PM. I can leave the app open and this will not change; there is no obvious way to force the app to refresh what is shown. If I terminate the app and then launch it again, it correctly shows a set temperature of 70 and FOLLOWING SCHEDULEI like the app but I cannot recommend it because of this behavior. When the app is already running and the user switches back to it, before presenting information to the user, it should always refresh the data since someone else may have changed the thermostat via local controls, someone else may have changed the settings via another instance of the app, or the previous app setting changes may be modified by a schedule, as in my example.

This app is definitely better than nothing! I enjoy being able to adjust the temperature and it does integrate with Alexa for temperature control, which is pretty nice. However, the app takes between 20 60 seconds to update with the current information on your thermostat. If you don’t realize this, which I did not for a very long time, you can often adjust the temperature and it doesn’t take. If you open the app and start adjusting the temperature, and then close the app… It just doesn’t work. When it finally downloads the current temperature, it will overwrite whatever you changed. I often work out of town and that’s the reason that I bought the thermostat. I would often remember that I had not adjusted the thermostat the day after I left, and it was very frustrating to think that I had changed the temperature and then come home and it was just running the normal schedule as though I was at home instead of being on hold for a week.All that to say… The base functionality of the app is to adjust the temperature while away. The fact that there is no indication of when the app is refreshing or that it may not take your changes… That just is unbelievable. Add a spinning circle or an hourglass icon, that says refreshing your data and then no one is confused. Also… Maybe work on how to get the information to flow a little faster than 20 seconds. That’s a long time when all you wanna do is adjust the temperature.

They have updated this app recently, maybe the 2nd to the last update basically messed this app up. Like what the others are experiencing, the scheduling function has been a nightmare since. I used to be able to change it and it will follow the schedule properly (or even if I leave the schedule alone). Now, the schedule won’t change until you go to the app and close it, open it again and maybe if you are lucky it will show “following schedule”, otherwise, you have to close and reopen the app several times. It is always showing “no schedule”. Also, before when I click and adjust the temp, it will give me an option to either hold for a period of time, hold temporarily or remove hold, now it does not do that all the time, sometimes I click out of the main page where you adjust the temp and go back and it will show up, most of the time I have to close the app out a few times to be able to get these options to show up. Also, I did not change any of the settings in the app nor the thermostats and the only thing that I change constantly is the temp and schedule which I used to do all the time and the app always follows the schedule. Obviously something got messed up on the updates, I wish they leave the app alone, I understand that it is necessary for security purposes but sometimes if it ain’t broke don’t fix it. Do not need the bells and whistles, just app the works because it used to. Please fix the bugs soon, its a great app when it actually works.

One of the best things about this app is its geofencing feature, automatically setting temperatures back when it detects all users are away from home, then back to normal when one of them is near, so users always come home to a comfortable temperature. You have to be logged into your Resideo account for this feature to work, and when you are, it works great. The problem is this app regularly logs users off for reasons unknown to me or tech support, and does so without notification, so you likely won’t know you’re logged out until you come home to a freezing or sweltering home! Literally no other app that requires I be logged in does this, so it’s really inexcusable. In the past 6 years at least, this is the only app to have unexpectedly log me out. Rating would be 5 stars otherwise.UPDATE: As you may or may not see, Resideo tech support responded to my review. That response lead me to removing 1 star from my original rating. In response to my complaint about the app frequently logging me out, the only app I have to do so, they told me to login every 24 - 48 hours! How is that a solution?! Clearly there’s something wrong with their system, and they apparently refuse or can’t fix it, so they want users to just put up with it. I’ve got 6 of these expensive thermostats in my home, so I either have to put up with it or spend a lot of money replacing them with Ecobees. I don’t recommend anyone buy Honeywell smart thermostats.
