This issue is so incredibly annoying I really hope I can help anyone experiencing something similar.
i managed to nail down one ZNP log that I think might be causing the issue
2024-11-30 23:14:05.822 DEBUG (MainThread) [zigpy_znp.zigbee.application] Sending packet ZigbeePacket(timestamp=datetime.datetime(2024, 11, 30, 22, 14, 5, 821157, tzinfo=datetime.timezone.utc), priority=<PacketPriority.LOW: -1>, src=AddrModeAddress(addr_mode=<AddrMode.NWK: 2>, address=0x0000), src_ep=11, dst=AddrModeAddress(addr_mode=<AddrMode.NWK: 2>, address=0x3E06), dst_ep=11, source_route=None, extended_timeout=False, tsn=1, profile_id=260, cluster_id=8, data=Serialized[b’\x10\x01\x0b\n\x00’], tx_options=<TransmitOptions.ACK: 1>, radius=0, non_member_radius=0, lqi=None, rssi=None)
ChatGPT says the following for this log
This log entry shows the Zigbee coordinator (0x0000) is sending a low-priority command to the device at address 0x3E06 on Cluster 8 (Level Control). The payload likely represents a brightness adjustment or related command.
If you’re troubleshooting:
• Check the recipient device (0x3E06) for acknowledgment or response.
• Monitor other logs for completion of this transaction (e.g., an acknowledgment or status update).
There is no other HA log that would make that specific device change brightness, so I really dont understand what is going on here, what could ZHA doing behind the curtain that is triggering these?
