Hue bulbs (direct connected) stopped working after 20.17 update

Well, pleasantly surprised!
2 out of 2 of my directly connected Hue bulbs that stopped working after the 20.17 update are now operational again thanks to the Philips Dimmer Switch!

  1. Turn the bulb off and then back on using the mains power switch
  2. Hold the dimmer switch close to the bulb. Hold the on and Off buttons for 10s. The bulb will flash a few times. I kept holding it during the flashing.
  3. After this, turn the bulb off and back on.

Following the sequence above, I was able to add the device as normal again using SmartThings.

Just for fun, after it was rejoined to my hub (zigbee channel 14) I checked to see if I could reset it again using the Hue dimmer switch. At first it didn’t work, but I tried a few things including turning off my Smartthings hub so it wasn’t connected to the bulb. Eventually managed to reset it again, and add it back into Smartthings for a second time.

So - really impressed by the Hue dimmer switch. From what I can tell, it’s just as good as the Lutron for resetting Philips Hue bulbs.

Successful on these bulbs:
Philips model: LWB004 (white)
Philips model: LCT010 (coloured)
