Bug Report

What happened

mosquitto_pub -h localhost -p 1883 -t zigbee2mqtt/bridge/unbind/0x00158d00044faf3e -m 'coordinator'

Doesn't seem to do anything, when I try to bind a group (or device)

mosquitto_pub -h localhost -p 1883 -t zigbee2mqtt/bridge/bind/0x00158d00044faf3e -m 'bedroom/desk_lamp'

It has the same effect, nothing is logged at all with log level set to debug?

What did you expect to happen

The device seems to send message to the genOnOff cluster

zigbee2mqtt:debug 2020-03-20 12:12:08: Received Zigbee message from '0x00158d00044faf3e', type 'attributeReport', cluster 'genOnOff', data '{"onOff":1}' from endpoint 1 with groupID 0
zigbee2mqtt:debug 2020-03-20 12:12:10: Received Zigbee message from '0x00158d00044faf3e', type 'attributeReport', cluster 'genOnOff', data '{"onOff":0}' from endpoint 1 with groupID 0

So I was expecting to be able to unbind it from the coordiantor, and then bind it to a group of devices... e.g. bulbs, so they would go off or on depending on the state.

How to reproduce it (minimal and precise)

Pair a Aqara MCCGQ11LM, try to (un)bind a device or group from it... It's odd nothing is logged at all, at minimal I would expect a 'not support' or something message to be logged.

Debug Info

zigbee2mqtt version: 1.12.0-dev (commit #ac8a84f)
CC253X firmware version: {"type":"zStack12","meta":{"transportrev":2,"product":0,"majorrel":2,"minorrel":6,"maintrel":3,"revision":20190608}}

More specifically, the idea was to test it with a bulb first... then to link it to a TRV

AFAIK these devices don't support binding.

[sjorge]

I guess we should at least log a message then? Doesn't look like z2m even attempted to bind though.

Also do you know of any that do support binding?

[Koenkk]

• Added an error log to the latest dev branch
• I've checked contact sensor using genOnOff cluster, these are Xiaomi (don't support binding) and the https://www.zigbee2mqtt.io/devices/DIYRuZ_magnet.html (not sure if it supports binding)

Can you confirm if it works as expected?

[sjorge]

Error log is working, but they are not yet 100% correct:

zigbee2mqtt:debug 2020-03-21 20:29:02: Received MQTT message on 'zigbee2mqtt/bridge/unbind/0x00158d00044faf3e' with data 'coordinator'
zigbee2mqtt:error 2020-03-21 20:29:02: Nothing to bind from '0x00158d00044faf3e' to 'Coordinator'

This should say 'Nothing to unbind' instead of 'Nothing to bind'

[sjorge]

It's a super simple fix: PR #3172

[Koenkk]

thanks, merged! 😄
