MQTT light isn't added to the entity register, doesn't have a button to change name & entity id

[nikolaykasyanov]

Home Assistant release with the issue:

0.77.3

Operating environment (Hass.io/Docker/Windows/etc.):

Docker, Raspberry Pi 3

Component/platform:

https://www.home-assistant.io/components/mqtt/

Description of problem:

I'm using zigbee2mqtt to expose ZigBee devices to Home Assistant. Until recently I only had some Aqara sensors and couple of plugs. I've added an IKEA bulb to the mix and encountered an issue. It looks like the bulb isn't added to the entity registry and thus doesn't have the cog button to edit its id and name in the frontend (I'm not sure whether these two facts are related though, please correct me if I'm wrong). The rest of the devices from zigbee2mqtt are present in the entity registry, their name & id can be edited.

Problem-relevant configuration.yaml entries and (fill out even if it seems unimportant):

mqtt:
  broker: 127.0.0.1
  discovery: true
  username: <edited>
  password: <edited>

Additional information:
zigbee2mqtt posts the following payload to the homeassistant/light/0x90fd9ffffe8287ab/light/config topic:

{"brightness":true,"color_temp":true,"platform":"mqtt_json","command_topic":"zigbee2mqtt/0x90fd9ffffe8287ab/set","state_topic":"zigbee2mqtt/0x90fd9ffffe8287ab","availability_topic":"zigbee2mqtt/bridge/state","name":"0x90fd9ffffe8287ab","unique_id":"0x90fd9ffffe8287ab_light_zigbee2mqtt"}

I wonder if it's related: #16303.
Upgrading to 0.78.0b2 didn't help though.

You are using the mqtt_json light component and I added a unique_id to the mqtt light in this PR. mqtt_json light doesn't yet support of unique_id.

@bieniu thanks for elaborating. Is it planned by any chance?

I could take a look if not, do you have any idea on its complexity compared to your PR to mqtt light?

@nikolaykasyanov It will be very similar to my PR for the mqtt light component. I don't have any mqtt_json light so I don't have the possibility to test the correctness of the change.
