My Zigbee2MQTT is continuously restarting. I recently had to change the adapter from ezsp to ember because of an update. I have a Sonoff stick E and updated to the latest firmware. This resulted in the following errors:
[2025-02-22 20:55:26] error: zh:ember:uart:ash: Received frame with CRC error
[2025-02-22 20:55:26] error: zh:ember:uart:ash: Received ERROR from adapter while connecting, with code=ERROR_EXCEEDED_MAXIMUM_ACK_TIMEOUT_COUNT.
So I read somewhere to add this to my config. yaml:
ota:
image_block_response_delay: 200
default_maximum_data_size: 15
That helped for a little while, but after a few days I had the same errors again. People advised to change the WiFi channel because it could be interference. So I did that and it worked, Zigbee2MQTT doesn’t fail anymore and I don’t get errors anymore, so far. But is it normal that Zigbee2MQTT restarts every hour or so?
