Pretty good
Thermostat itself is good, lots of options for adjusting temps. However temps can get mismatched going between adjusting something on the app and on the attached box which got very frustrating recently when trying to set it up after adding another heater. The graph is much easier to read on the physical box vs the app as the app only seems to do increments of 10 degrees which is difficult to see slight variations and I can’t find a way to zoom in, even if I change between 1hr/12hr/1 day. Would also be good to be able to mute the alarms from your phone VS having to wait for the temp to get in range/manually muting it on the thermostat. Overall thermostat good but some minor improvements to app would be good.
