You can schedule temperature changes throughout the day. Or set a geofence that starts warming or cooling your space as you head home. The app alerts you when

Great when it works

I’ve had this for probably six months now. My only complaint is that sometimes it doesn’t recognize that my wife is home. I set it to give me an alert and I keep having to turn the geofencing feature off until I get home. Aside from that quirk it is terrific.

Second complaint is data logging, or the lack thereof. It’s not a comfort issue or anything like that but I find it amazing that there’s no way to see how many hours it’s operated or in what mode and what the temperature was say every hour for at least a day or a week. At one point I set the modes too close and believe that it would heat up the house then turn on the A/C to cool it back down. With a data log feature I’d have seen that sooner.

My wife is disabled and we don’t leave the house at regular times each day so the competition’s device that “learns” your schedule was of no use to us. In theory this is a much better option however Honeywell needs to build in a data logger and definitely needs to fix the Geofencing reliability. At the very least give us a button to override the home/away and/or refreshing the search when we know for a fact that someone is home.

As needy as a 2 year old

The thermostat itself is pretty good. I don’t have any complaints. The app? Well, that’s a whole different story. The constant alerts and notifications are as annoying as a toddler who is bored. They both are incessantly begging for your attention for no good reason. Why does the geofencing glitch out? Who knows! Why does the connection fail multiple times a week (and sometimes per day)? Who knows! The good news is I can just ignore the alerts and it usually resolves. However, my T5 device disappeared from my app device list. I have been through the “add new device” setup about 10 times and it gets right to the end where you answer some questions about your heating/cooling and then gives an error about being unable to complete set up or something equally non-explanatory.

The app worked for a good long time with just the annoying notifications being the issue. Now the app refuses to let me add my thermostat. be the judge. If you want a nice touch screen thermostat, you’ve got it. Besides that, there I absolutely no guarantee it will be “smart” because the app has become useless. Sigh. Who has the time for this? Not me.

The Honeywell App for Lyric Is Absolutely Useless

We got the Honeywell Lyric thermostat because of the Honeywell reputation. Installed in our newly built home and it is a very nice looking thermostat that works fine manually. The Honeywell app for it is horrible. Can’t believe Honeywell would put out such an inferior, useless app for its product. VERY disappointed - we got the unit to be able to control it when we are away, but it doesn’t stay connected to our WiFi and the app is so basic and rudimentary - it does not have any features that mirror the device other than temp up or temp down. What a huge waste of money this thing was. Would return it if I could. Honeywell, if you care about customer satisfaction you should invest in better app technology so, at a minimum, all your devices features are accessible via the app. Would NOT recommend this device until Honeywell upgrades their app to have a stable WiFi connection and has significantly greater features on their app. Until that happens, this product is a waste of money if you’re need if flexibility and control when away from your home. Also, I rate customer service “0” because I called and waited for 30 minuets and was still “waiting for the next available representative” - VERY FRUSTRATED!!
