Grouping functionality is essential!
Currently we do this with Alexa, but this is only good for "turn upstairs on/off". When setting smart schedules it is still frustrating having to do the same schedule for each and every room.
I have 10 radiators, all with a smart TRV.
I have one smart thermostat in my kitchen/diner/lounge (both rads in this area have smart TRVs too)
I have kind of worked out how to group areas through Alexa but it isn't exactly user friendly.
it involves me not using the Tado app, which i would normally use to control heating in individual rooms (which I do more often).
There are unscheduled times when we want to heat all of downstairs or all of upstairs, but leave the other 'zones' off. Equally, I might want to heat just occupied bedrooms upstairs rather than all of upstairs.
To do this, i would have to go into each bedroom individually, and increase the temperature of each. rather than simply being able to heat 'Bedrooms' or 'Upstairs' or 'Downstairs'.
I would welcome a drag and drop feature so I can maintain individuality of my rooms, but also be able to quickly change a group, without using Alexa.
