The thermostat in itself is okay, but it won’t work well with the app, so it can only be used at home manually. Tried reaching out to support, but they’re not reachable and hang. I would have chosen a different product if it wasn’t preinstalled in the home I purchased.
The T6 can be controlled from anywhere in the world. My home has a one AC unit for downstairs and upstairs. I have 2 T6 thermostats. They work great. I am able to keep upstairs warmer in the summer since it is not being used a lot and the downstairs is set perfect.
