T5 thermostat

Typically, we have zero issues with the app or our thermostat. Lately, it has been quite frustrating. The geofencing feature has a mind of its own and seems to work when it wants. The app stopped recognizing our thermostat resulting in me having to set it up again. Not a big deal, right? Well, I spent 30-40 minutes standing in front of the thermostat going through the setup process in the app a good 10 times. System still doesn’t work and the app shows I have no devices setup. I eventually gave up and will try another time. Extremely frustrating. I got to the end of the process several times and was prompted to configure the device and then register it (which I have already in the past). It would think for about 3 minutes and eventually give me an error message. Then would say setup incomplete and prompt me to start over...

Honeywell, never had issues before. What’s going on and how can I make this function properly again? This is the second smart thermostat I have had made by Honeywell. First one melted and almost caught fire... thank you

Used 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.

Terrible geofence and tech support

I’ve had a Honeywell Lyric thermostat for a few years now and up until recently, the interface between the app and thermostat worked like a charm. Recently however, (since they changed to the Honeywell home app) the geofence has been sporadic at best. When I get home after 9 hours away at work to find that the thermostat never turned down and my house has been toasty warm all day, it is beyond frustrating. If it only happened once or twice I would have an issue with it, but it has occurred many times now. I tried contacting tech support (because they were extremely helpful when I purchased the thermostat) only to be left waiting for a rep for over an hour with no response (three times now). I also tried chatting with a tech support rep with a similar hour plus wait with no response. My final attempt at emailing tech support was responded to after about a week (despite the fact that their web site says they will respond within 48 hours). Unfortunate the email response did not provide a solution so I responded to the email with additional information. That was over a week ago and I have still not received a response. I would have highly recommended the Honeywell Lyric and app in the past. However, after this experience I would recommend another brand with more stable service and more responsive tech support.
