"This app is horrible to use. It is a replica of the interface but the screen and buttons are so small, it is basically impossible to easily use. Our furnace guy put this in and got rid of our old Web based thermostat and app, and I really want my old one back."

"Difficult to get a single heat-to or cool-to temperature for all hours of the day, as opposed to dealing with multiple time ranges."

"Thermostat indicates fan is set to auto regardless of setting. Sometimes sets thermostat to a different temperature then I set it to using this app. It would be nice to access the installer options by holding fan button on the app."

"On the Windows & Android app, the Fan Mode always displays ``Auto`` regardlee of the actual setting. Other than that, it works fine."

"HVAC doesn`t start running when using the app. Example- this morning I awoke to 62. I wanted to warm the house to 70 before crawling out of bed. Used the app to raise the temperature to 70, waited about 5 minutes, and heater never started running. Went to thermostat and it displayed my request but it wasn`t until I tapped a key on the display that the heater turned on. It totally defeats the purpose of the app if you have to make physical contact with the thermostat to make the HVAC run. It has been like this since at least the last update."

"The app is clunky on Android. It doesn`t render to the full size of your display. Basically identical to what you have on the wall but super tiny. Works as well as the Ecobee3 but less refined. Sucks that you supposedly have to use this thermostat if you want your equipment to function as intended."

"This might be the worst app I`ve ever encountered. Utterly useless. Keep me
logged in until I log out? To this app that means `make me log in every
time you touch me`. Negative *****"

"Very inconsistent operation. Works sometimes, and other times fails to control thermostat. Honeywell program and thermostat much more useful."

"Buggy and clunky. When it works it is clunky but okay, when it doesn`t work
it does really stupid things. For example, last night I was hot so I turned
down the temperature one degree to 75 from my phone. I woke up early to the
AC running full blast and the house 69 degrees. The thermostat still showed
being set for 75."

"As other reviews have stated, it does not communicate well. You change settings on the app and they do not reflect on the thermostat or vice versa. If I change the temp on the thermostat the app does not reflect this. It has been pretty useless which is really a bummer because tempstar is a very high quality HVAC company. Their equipment is top notch and mimics their brother company, Carrier. What upsets me the most is that they have put tons of R&D into the carrier thermostats but they do not work on tempstar equipment. The carrier thermo and app even work with alexa now. Please fix this baby up temp star."

"The app does everything I expect and on my system it has worked for about a year now. Initially I had a problem with the router not pinging it timely and it not triggering. I have it hooked up now to a mesh Network and there have been no issues"

"I cannot change the temperature to Celsius? You would think temperature selection is important for a thermostat!!! Also, there`s no online customer support. How about you let Nest and Ecobee take care of this?"
