[Feature Request] Show only temperature of specific entity

[adandl]

Hello!
The climate group is very useful - thank you very much.
Just one question - I have three thermostats which I have in one group.
of course they have little different readings.
Which actual temperatur is shown on the group element?
Thanks a lot!

The average temperature is shown.

Sorry - I was away during new year :).
Is it possible to change the interface to show the temperatur from only one instead?
I have a wall-mount device in the group which has it's own reading and that is the one I'd like to display

Yes this could be implemented. However I do not have the time to do this.
You would need to add a configuration variable like:
display_value: average|entitiy_id

I have made an initial (not tested) implementation here:
#28

you have to add:

master_device: entity

to your config

Thanks for this component, I'm trying to use master_device: but I'm getting the following error when I try to use the master-sync branch (with ha 2021.5.4):
