without the bridge or dimmer the only other way(s) to reset a Philips hue bulb is using an Alexa echo with the zigbee feature or a raspberry pi using the hue thief. You need to reset before you can pair the bulb with ZHA or another hub. I had exactly the same problem.
Put bulb right next to zigbee stick, power cycle bulb off and on, select touchlink and zigbee2mqtt will reset the bulb. Not sure why this method is not in the homeassistant docs, but it works. I reset 3 bulbs this way. Since the stick is $11 bucks from aliexpress, might be the cheapest way. Ditched my depreciated Hue Bridge v1 this way.
I used Touchlink, Hue thief did not work for my stick (Hue Thief is for Silicon Labs chip and I have a TI Chip).
After resetting bulbs, I also tried both ZHA and Zigbee2mqtt (via addon) to control them. Decided on Zigbee2mqtt because seemed a little more stable for me.
any guide on how to use touchlink to reset the bulb? do I need to install touchlink seperately? zigbee is very new for me… so many things are un explore…
The link to the touhlink guide is in the post above. The full documentation is here: Home | Zigbee2MQTT
Basic steps:
Install Zigbee2MQTT (I installed as a home assistant addon). You use this instead of the built-in ZHA integration. Directions in link above, but you add a custom addon repository.
Only thing I had to configure is the addon configuration is the device (the sonoff stick is “port: /dev/ttyUSB0” and make sure “permit_join: true”
Give it time to start up, like a few minutes.
Put the bulbs right next to the zigbee stick. Turn bulb off/on right before next step.
Click Touchlink in the Addon Web Interface, click scan, then factory reset the bulbs it finds
Just deleting the bulbs from the ZHA network worked for me.
I just removed the device and started searching for new devices on my other home assistant instance.
Thanks, this was throwing me off. I deleted the light from the hue app and opened dconz then photoscon, scanned for lights. Turned light off for 3 seconds and back on and instantly recognized with no reset needed.
Do new Hue bulbs which have not previously been paired to a hub have any specific requirements to begin the pairing process via ZHA or does it just start automatically once the bulb is turned on?
This popped up on google when I couldn’t get a refurbished Hue lamp to sync to my zigbee2mqtt. Going to Touchpoint > reset fixed it for me. Thanks for this!
Use your bridge. Make sure both bulb and bridge are powered at the time you are deleting it through Hue app. If bulb is not on it will not receive the wipe and will still search for that bridge. Learned the hard way.
Then after removal from Bridge go into ZHA and click discover devices. It usually takes around 5 sec between deletion in app to being visible in ZHA
