Homey Pro (2023) v13 Multi-PAN Zigbee Queue Lockup & 90-97% TX Failures

Hi everyone,

I’m struggling with severe Zigbee instability on my Homey Pro (2023) running firmware v13.5.3 (Multi-PAN stack). Despite trying exhaustive troubleshooting (overnight power-offs, minimal setups, device re-pairings, and full firmware re-flashes via USB recovery), the network remains completely stalled.

Symptoms:

  • TX failure rates are through the roof (90%–97%) on both battery sensors and mains routers.
  • Command queue is constantly blocked / timing out.
  • State desync: Manual button presses on devices (like IKEA/Tuya plugs) instantly update the app, but sending commands from the app to the devices always fails with communication errors.
  • Certain older devices (like a long-standing Tuya plug) seem to flood the queue, but even clean IKEA plugs fail to respond.

Has anyone found a stable workaround or fix for the v13 Multi-PAN queue lockup without doing a full Zigbee network reset? Any advice or developer insights would be greatly appreciated!
