1. 5/5Not updating unless restarted

   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 SCHEDULE I 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.

2. 2/5Glitchy - Learn the loopholes

   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.

3. 2/5Used to work great

   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.

4. 2/5Best feature is worst part.

   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.

5. 3/5It’s okay, but glitchy sometimes

   Sometimes it does some bizarre stuff. I have the latest version installed according to iTunes, but for example just now I noticed that my AC was running and the physical thermostat showed a set point of 76, when my schedule in the app should have it set to 78 when I’m at home. So naturally I opened the app, and a sign in was required (so it seems to randomly sign me out?). I signed in, and it showed “using home settings”, but the set point was 76 even though the schedule says 78 for my home settings. When I clicked on the schedule button, it shows my home settings to be set for 78. So why is it saying that it is using my home settings but set for the wrong temperature? I manually changed it to 78, it stopped cooling, but then said “hold 76 while home” (so what the heck??) even though the set point was now 78?! I tapped and selected to remove hold, and it is back to normal, but this type of thing happens more often than I would like (this is definitely not the first time). I also would like to see a feature to hold a temporary set point for a specified amount of time rather than always holding until the next event. This would be handy if you want to run it just for a few minute and then go back to normal, like almost every other programmable thermostat… And my final complaint is that it doesn’t show you an up to date run time for some reason. This seams like such a basic thing but it takes two days before you can see any runtimes so you are always missing two days worth of data. In todays day, I don’t see any excuse for these types of bugs and lack of features.
