What is the feature?

Description

When operating many thermostats, it would be nice to have a capability for a master switch that could turn off all thermostats. What I mean is that one can set the thermostats to heating mode, set temperature, but if master switch is turned off, it would:

• Show to user that heating mode is enabled, but currently it is disabled due to master switch
• All running TRVs would close
• When master switch goes on (allow heating), TRV configuration remains as it was before master switch off and TRVs start operating further.

The motivation on my side is that I often leave apartment for a week or even more and thus disable the TRVs. I have many, and today I do it one by one from the dashboard. I could create an automation that would put all of them to off and then to heating later. I think a master switch would be a better option. This could be a simple toggle helper input.
