Thank you for your helpful advice Wayne-TP. I have three KE 100 thermostats. I successfully setup the Kasa hub and linked it to the first KE 100 thermostat in my bedroom; I have also set up a schedule for it coming on at certain temperatures during the day and it worked fine. The other two KE 100 thermostats I am installing on two radiators in my large sitting room, I also have the hub in that room. I intend to put the T310 temperature and humidity sensor in the living room. So will I be able to only connect it to the two thermostats in that room to control just those two. I assume it will not have any effect on the one in my bedroom? TIA
