As far as I know, there is no way to tell Adam the temperature or the need for heating, in a room. This is only possible with connected thermostat (don’t you have one?), or Lisa/Tom/Jip in other zone’s.
Are you sure you want to go this way? I wouldn’t want to rely on any home automation to control this central part of my heating. Or try to emulate the (very complex) thermostat functionality.
