MQTT sensor with device_class enum does not support options

nuessgens commented 1 month ago

The problem

I tried building sensors which are automatically discovered via the MQTT discovery. I have the usecase for enum / limited set of (non-numeric) states (e.g. presence in 'free', 'in-call', 'off' or wind-direction in 'N', 'NW' etc.)

It seems that this is not supported (at least for MQTT sensors; because e.g. the charger_type of the companion app exactly this is done). Unfortunately therefore all the visual editors provide no drop-down with possible values of such entities.

I was assuming that with #89391 device_class enum was introduced for MQTT sensors

Additional information

Here is a config-example for my "presence" / busylight use-case

}

MQTT state msg: Topic: busylight_msteams/host1/state Payload:

  "state": "free",

But in the Developer Tools > States Entity it just shows Entity: sensor.host1_busylight_msteams_state State: free State attributes:

device_class: enum
icon: mdi:microsoft-teams
friendly_name: Microsoft Teams Präsenz (host1) Microsoft Teams Präsenz

https://github.com/home-assistant/core/pull/123248 will add support for this. That it is not supported yet is not an issue though, it is a feature request. So I am going to close this as it is not an issue.

Tanks for the quick reply.

You are totally right: this was rather a feature request.

Regarding the pull-request: amazing! that was lightning fast 😎 Looking forward to the next release ;-)
