After my IKEA Tradfri GW integration stopped working after a GW update (completely losing contact 1-24h after HA restart), I got a Conbee II USB stick and added it with ZHA in HA.
I could add all my Tradfri bulbs and one plug, and when they work, the response time is great.
The problem is that the devices become “unavailable” randomly all the time. A power cycle of the bulb makes it appear again. Also, sometimes they are not listed as unavailable but still does not respond to being turned on/off. They also randomly report the wrong on/off-state.
The HA log is full of different zigbee related errors such as:
Failed to receive transmit confirm for request id: 42 16:05 components/zha/core/helpers.py (WARNING) Unexpected transmit confirm for request id 137, Status: 0x00, 137 16:53 __main__.py (WARNING) No response to aps_data_request command 16:53 components/zha/core/helpers.py (WARNING) - message first occured at 16:04 and shows up 57 times Error while sending frame: 0xd0 16:53 components/zha/core/helpers.py (WARNING) - message first occured at 16:04 and shows up 13 times
Anyone else using the Conbee II with ZHA?
I’m on 0.93.1 for HA and 26490700 for the Conbee firmware.
