“Do these work with biomass systems? What happens with Tado if 2 people in the house have smartphones:
Can Mrs i and I both be linked to Tado? If I’m at work and she’s out will it respond to either of us coming home?
What if we have rellies staying and we pop out with them at home – will Tado turn their heating off?”
Yes you can have multiple phones with the Tado, I have mine and my wife’s linked and it knows when either of us arrives home, we were away a few weeks ago and my daughter was staying in the house on a not particularly cold day, I could see she had turned the CH up to 23 so I was able to turn it off remotely 😉
