Hello,
I would like to install the multizone_thermostat component.
I put it in custom_component and when I relaunch HA I have this in the log file:
2021-12-07 14:47:12 WARNING (SyncWorker_0) [homeassistant.loader] We found a custom integration multizone_thermostat which has not been tested by Home Assistant. This component might cause stability problems, be sure to disable it if you experience issues with Home Assistant
On the other hand, I have nothing in the integrations nor in the cards …
The problem is that, precisely, I don’t have a “multizone …” type integration and when I try to integrate a card, there is nothing that refers to “multizone …”
The thermostat at the moment can only be configured via yaml, configuration via the interface is not possible. I think you are trying to add a lovelace card to visualize it in HA? You first have configure a thermostat itself in yaml and then you could add a lovelace thermostat card which refers in your case to climate.on_off.
