Tado: see room timer in HA

I have replicated the Tado UI in HA (with some customisations), and I’m much happier with mine vs. the Tado app. However, one thing I can’t do, is show the time remaining when a room is set to heat “for 30 minutes” etc.

In the Tado app, it says “Until 14.35” at the bottom of the room, for example, when the heating is active, and “next change, 20.0 at 18.30”. I’m not too bothered about “next change”, but, when the heating is active, I’d love to be able to find out how long for, from HA, so i can display similar information directly in HA.

Thanks!
