Record current temperature at selectable intervals (1hr / 30mins / 15 mins) and store them in along side the hours/mins in the Insights section. Will give a good view of how long it takes to heat/cool your home. Outside temp would be a nice bonus too.
I’d like to see the current real-time humidity shown on the physical display of the device. Right now the only way to retrieve it at all is in the main app page for the thermo. The data is in there, just put it on the screen.
