Good evening,
I just integrated my water heater via the matterbridge-plugin-cozytouch plugin:
Thanks @mutmut for the link 
All information is correctly displayed in matterbridge:
The information is correctly updated according to the logs:

I then added the different elements via the matter plugin of Gladys:
And I added them to the dashboard:
As you can see, the water temperature does not seem to be displayedHowever, no issues with the switches after the first activation/deactivation via Gladys, the sync with the app works very well.
Do you have any idea about the water temperature that comes up in matterbridge but not on Gladys? Or even a debugging tip?
Note that the water temperature doesn’t even appear on the cozytouch app
PS: I intentionally disabled the setpoint temperature as it is not adjustable on my device
