I have a Tado system I bought in 2014 to run the heating in a holiday home in France (I live in London UK). It consists of a Smart Thermostat, a Temperature sensor and a Bridge.
The temperature sensor is a wireless unit run by a battery charged by a small solar panel, I think the battery is beginning to lose its ability to keep its charge. Is it possible to replace this sensor with something new? If so what do you suggest? I dont want to add anything else such as radiator taps or A/C>
