I have 3 GU10 Tradfri bulbs in a single light fitting, and have had them paired with zigbee2mqtt using a USB CC2531. Been working fine for over a year.
Today, all 3 bulbs had disappeared. Other zigbee devices are connected and working fine, apart from those that were connected to the now un-paired lights. No biggie, I thought; just reset and re-pair the bulbs. I enable join mode in zigebee2mqtt via the webUI and look at the logs. Then I do the on/off flick 6 times and the lights start pulsing. Usually nothing at all appears in the log, but once I did get:
Info MQTT publish: topic 'zigbee2mqtt/bridge/log', payload '{"message":{"friendly_name":"0x680ae2fffe138133"},"type":"entity_not_found"}'
Error Entity '0x680ae2fffe138133' is unknown
repeated for the other 2 bulbs, with their appropriate IDs.
Iāve rebooted HA (running hassio in docker on ESXi), disconnected any other nearby zigbee bridges, and tried the pairing process several times but now Iām out of ideas.
Hmm, I donāt have āMQTTā under dev tools. Iāve installed the MQTT Broker via the UI add-on store and have my mqtt server defined in my configuation.yaml as below:
Is there anything else I need to do? Stuck at the first hurdle!
Edit: Found it, itās been moved. I get device not found when I try to remove it using āzigbee2mqtt/bridge/config/removeā and I also donāt see them using MQTT explorer, so I assume theyāve already been removed automatically. They donāt appear in HASS. Still canāt re-add them.
Iām still unable to re-add these lights, despite them already being removed from Zigbee2mqtt and HA itself. I get nothing in the logs when I try to add them. Anybody have any further things for me to look into?
Thanks @tamsy! Iāve just downgraded to MQTT Broker 5.1 as per that thread, and can see a lot more in the logs now, but sadly still nothing regarding these bulbs.
Nothing at all sadly. Which points at an issue elsewhere, but these bulbs are in the same spot as they were when I originally set them up with zigbee2mqtt.
Maybe try (another) reset of the bulbs? From ON to OFF 6 times until they shortly blink once.
And did you make sure that zigbee2mqtt has āpermit_joinā set to ātrueā and the addon has been restarted after this was set?
Iāve been doing it from ON to ON, turning them off 6 times in between. This does result in them pulsing, and eventually (presumably timing out) and just turning on solid.
Iāve enabled permit_join but didnāt restart zigbee2mqtt in between attempts. Trying that now!
As for that setting the addon has to be restarted once for the setting to take effect. Donāt forget to do the same if you want to forbid permit_join (false) again.
Thank you for the suggestion, but I still donāt see anything in the zigbee2mqtt logs after restarting the addin. I also restarted the mqtt service and HA itself just in case.
You wrote that all 3 bulbs disapeared all of a sudden just like that. Can it be that i.e. a voltage spike or a lightning strike has happened in the neighborhood of your home which fried the zigbee chips? Maybe you can try to pair them at a different place, some friendās or relativeās home?
Thanks so much for your help @Tamsy
I feared that this may be the issue. Unfortunately I donāt have any other GU10 fittings elsewhere in the house for testing, so I might just try getting a new bulb to test with.
I thought rebooting my container or HA would have been the same as unplugging and reconnecting this but apparently not! After doing this and attempting pairing again it worked immediately. You have no idea how long iāve been standing in the hallway flicking these goddamn lights on and off.
