It’s not that difficult to support Farenheit, I guess. Sadly I have not too much time to work on this. Feel free to look at this.
Installed this via HACS (0.3.2) on 108.8. But cant get it to work. What am I missing? Screenshot of group and one of the thermostats:
Hmm it seems that 108.8 broke it somehow. I am on 108.6 and it still works fine. I will have a look when I will update. It seems as if it does not get the state updates anymore. Is there anything in the logs?
I just updated to 108.9 and it still works for me. Can anybody else confirm the issue?
Nothing I could find in the logs right away. Semms to not pick up the Mill heaters. After testing it in my other HA setup at home I belive the problem might be the millheat integration. Because at home we use basic-z-wave thermostats, and there the custom component works as expected. Maybe they do not work well together?
Any Ideas?
It might be something about PRESET_MODE, if the thermostat does not support it, it seems that it does not work then. But I am not sure yet. For me it does work indeed, so it is a bit hard for me debug…
Seems like you are right, the Mill heaters does not have a PRESET_MODE.
State atributes in the Mill heater climate entity :
hvac_modes:
- heat
- 'off'
min_temp: 5
max_temp: 35
target_temp_step: 1
fan_modes:
- 'on'
- 'off'
current_temperature: 20
temperature: 20
fan_mode: 'off'
hvac_action: idle
open_window: null
heating: 0
controlled_by_tibber: 0
heater_generation: 2
room: stue
avg_room_temp: 20.5
friendly_name: gang
supported_features: 9
Possible to work around?
There is a discussion ongoing here:
https://github.com/daenny/climate_group/issues/20
Can you try with this version (copy and paste to config/custom_components/climate_group/climate.py):
https://github.com/daenny/climate_group/blob/test/more-logging/custom_components/climate_group/climate.py
and enable logging in DEBUG (https://www.home-assistant.io/integrations/logger/) for the component?
I made a new beta release that should fix the problems.
As mentioned, I think this should be a standard features of HA; any particular reasons you’re not creating a PR to merge this upstream?
it would prevent breaking things that often.
I don’t mind doing this if you’re lacking the time.
With 0.113 this component isn’t properly working, current_temperature and temperature are always showing as null.
hvac_modes:
- fan_only
- heat_cool
- ‘off’
min_temp: 15
max_temp: 30
current_temperature: null
temperature: null
friendly_name: All Zones
supported_features: 1
when here I’ve only put a single entity in it, which has
hvac_modes:
- ‘off’
- fan_only
- heat_cool
min_temp: 15
max_temp: 30
target_temp_step: 0.5
current_temperature: 19
temperature: 18.5

Good point. I might have time to add a MR to home assistant this weekend.
I am on 0.114 and it still works for me, but I also only have quite simple climate devices.
I really like the Climate Group component, especially how the group is a climate entity itself. Works great with my automations and the simple thermostat lovelace card.
The only thing I wish it did was to synchronize the thermostats in the group. ie. If I change the temperature or preset mode of one thermostat, I want them all to update to the same.
Do you think that’s something the component could be capable of?

For the time being you could create an automation that is triggered by setpoint changes of the individual thermostats.
Awesome work, looking forward to testing it out!
Would it be possible to group together, multiple TRVs, with temperature readings from another thermometer placed in the room for more reliable numbers?
I just created the following automation for that:
- id: heizung9
alias: ***
trigger:
platform: state
entity_id: climate.heizung_wozi, climate.heizung_wozi_2
attribute: temperature
action:
choose:
- conditions: "{{ trigger.to_state.entity_id == 'climate.heizung_wozi' }}"
sequence:
- service: climate.set_temperature
data:
entity_id: climate.heizung_wozi_2
temperature: "{{ trigger.to_state.attributes.temperature }}"
- conditions: "{{ trigger.to_state.entity_id == 'climate.heizung_wozi_2' }}"
sequence:
- service: climate.set_temperature
data:
entity_id: climate.heizung_wozi
temperature: '{{ trigger.to_state.attributes.temperature }}'

Awesome work zubredo, so if you change the temperature on the physical dial on heizung_wozi_1, it will automatically mirror the change on heizung_wozi_2?
And looking at the logic of your automation, would the below work, if I actually had 3 in the same room?
- id: xxxx
alias: TRV Sync
trigger:
platform: state
entity_id: climate.trv_1, climate.trv_2, climate.trv_3
attribute: temperature
action:
choose:
- conditions: "{{ trigger.to_state.entity_id == 'climate.trv_1' }}"
sequence:
- service: climate.set_temperature
data:
entity_id: climate.trv_2, climate.trv_3
temperature: "{{ trigger.to_state.attributes.temperature }}"
- conditions: "{{ trigger.to_state.entity_id == 'climate.trv_2' }}"
sequence:
- service: climate.set_temperature
data:
entity_id: climate.trv_1, climate.trv_3
temperature: '{{ trigger.to_state.attributes.temperature }}'
- conditions: "{{ trigger.to_state.entity_id == 'climate.trv_3' }}"
sequence:
- service: climate.set_temperature
data:
entity_id: climate.trv_1, climate.trv_2
temperature: '{{ trigger.to_state.attributes.temperature }}'
yes, I think that should work. Have you tried it?
Nope, I wanted your confirmation, before testing it out. So will do that now. 
I forgot to ever write back. I can confirm that it is working with 3 units. 
Hi Zubredo, unfortunately with the newest 2021.3 update, it has started to give failures.
The messages are the following:
2021-03-14 21:16:58 ERROR (MainThread) [homeassistant.components.automation.trv_sync_common_room] TEM04 - TRV Sync - Common Room: Choose at step 1: choice 2: Error executing script. Invalid data for call_service at pos 1: must contain at least one of temperature, target_temp_high, target_temp_low.

So it appears that Home Assistant requires me to set a temperature, even though I just want it to mimic the one I changed manually.
Any ideas on how to make Home Assistant happy?
The automation is below:

Edit: I have created a separate topic on the same:

And @pnbruckner has already suggested a working fix:
