Bug Report

What happened

None of my Gledopto GL-C-008's show any linkquality anymore.

What did you expect to happen

Inspecting topic. I would assume I even see linkquality-key in JSON-payload. It's missing.

How to reproduce it (minimal and precise)

I can't reproduce it cause its absence is the issue.

Bulbs normally don't send any messages to the coordinator, therefore we don't know the linkquality. You can achieve it by e.g. executing a get by publishing to zigbee2mqtt/FRIENDLY_NAME/get payload {"state": ""}

Hi, Why does the Gledopto has a linkquality sensor? Is it obsolete? The docs show that sensor.

Some of the same Hue Bulbs show linkquality in history while the other doesn't. 1 Hue Iris has linkquality key while the other hasn't. Almost all IKEA leds show linkquality. I don't get the behaviour.

Because all devices potentially can have an LQI
