I ordered a Tado late November and was informed 16th December shipping. It eventually arrived 23rd December.
Self installation was ok even though our existing heating setup was a bit non conventional. Google is your friend for wiring diagrams etc.
So far it’s been very good. It switches off when we leave the house and back on when we head home. The app and website are great, easy to use.
It switches on quite early in the morning to achieve the desired temperature at wake up time but I think this is because it’s still “learning”.
The house certainly seems warmer than it was, which was not the aim, but might suggest Tado controls the heating more accurately then our old thermostat. With the old controller it was always to hot, too cold or maybe somewhere inbetween,Tado seems more steady.
I’ve taken meter readings and I’m going to compare daily consumption with last Winter to see if the savings pan out, but I’m going to take additional readings from time to time and cut out the learning period to get a more representative measure once Tado knows how to heat our house.
