How does Roborock handle mapping data, and where can I find the stated policy?
How many on/off options does this have?
Is it necessary to set up Geofencing? Can you just programme in times instead?
Can the temperature be set using the remote sensor? I want the remote sensor's room to be at the desired temperature (no averaging).
Which is superior, the Nest or the Honeywell?
I have a hydronic radiant system with 11 zones. How does this work with a system of that type?
Does this require a Redlink hub, or does it function via the internet alone?
I own three a/c units and three thermostas (3 honeywell t5s). Would I want three t9s? or are I able to obtain one T9 and two or more sensors?
In adjacent rooms, I have two fan coils, each with its own thermostat (24v). Can they cooperate to regulate the total temperature?
