Radiator hides in multiple rooms
I have Tado smart radiator thermostats installed in multiple rooms on radiators with radiator hides. It works not very good. I need the termostats to work by an external thermometer. Can I only ude Tado smart thermostat or can I use other brands and connect them to Tado (via ifttt) I need probably 3 external thermometers and it might be too expensive to buy 3 Tado smart Thermostats.
