Allow "Auto" within HomeKit
Many smart heating systems when exposed to HomeKit allow the use of "OFF, HEAT and AUTO", even Drayton Wiser which can only be exposed through a custom made plug-in via homebridge can use AUTO.
The AUTO function (at least as I see it) would allow the system to return back to the current schedule. For example, in HomeKit I have a custom Boost Living Room scene that will set the living room to 25deg for period of 40 minutes (with the help of Tado's Manual Control setting within their app), yet I can't return to the original schedule without going into the Tado app and resuming.
Considering this is marketed as 'Works with HomeKit', It's impossible to use Tado with HomeKit exclusively and get the same 'core' function.
