@Pbenichou In the suggestions part of this site there is a long-running thread asking tado for this but I'm afraid we do not know where it sits in their priorities for change.
I've just post on suggestion thread. We're allowed to dream ;-)
When Amazon bought Tado I hoped they will get moey to do what they promised.
They sis not what was promised on their roadmap but instead some funny features nobody asked for and nobody I now ever uses.
