IKEA Tradfri lights don't remember last used brightness between HA restarts

Configuration Zigbee
1

Whenever Home Assistant restarts, IKEA lights turn on at 0% brightness, regardless of what their previous value was.

  1. Turn light ON at 70%
  2. Turn light OFF
  3. Restart Home Assistant
  4. Turn light ON
  5. Light is now ON at 0% (very dim)

I’m using the Home Assistant container, 2022.4.7
Please help!

Did you try re-pairing the device with ZHA?

Recommend upgrading firmware on your Zigbee Coordinator regardless as well, just to try to rule that out.

If still have the same issue then suggest report to → https://github.com/home-assistant/core/issues

See https://www.home-assistant.io/integrations/zha#reporting-issues

and https://www.home-assistant.io/integrations/zha#debug-logging

There is also new diagnostic information that you can get from the ZHA integration, this can be acquired by clicking on the “Download Diagnostics” button in the device settings.
