Not my understanding from reading all the info on their website, if I already have a thermostat I can just replace that with a smart thermostat
About the tado° Extension Kit
If you have an individual boiler (e.g. gas or oil central heating or heat pump) and a wired room thermostat you don't necessarily need the Extension Kit.
If you have an individual boiler with a wireless thermostat, or no thermostat at all, you will need the tado° Extension Kit to function as a wireless receiver.
For the vast majority of the time is there any point to being able to control the heating of your home remotely?
I don't want to turn up the heat while I'm still in bed...
Ha ha. You missed my point. I'm not saying I don't want to be warm in bed; I'm saying:Maybe; but have you asked the Missus?![]()
Besides, my wife has a human hour water bottle right next to her, so if I'm warm enough she's warm enough.I want the system to get it right for me, with me having to intervene as infrequently as possible.
