I have purchased a Hue Wireless Dimming Kit in the UK which contains White bulb paired with a Hue remote. I could get the remote paired to ST without any issues, but the bulb was effectively ‘orphaned’ as a standard bulb. As others have experienced, nothing would get it to be discoverable by ST.
Following the thread above, I found a cheap Philips LivingColours Remote and I paired that with the orphaned bulb simply with this video. To reset the bulb I held the On button with Scene 1 together and this reset the bulb. It was immediately discovered by ST.
My ST is on channel 19, and I can’t discover the Philips LivingColours Remote as a thing to connect to my ST, so I’m assuming it’s a channel incompatability issue there. That’s a pity, as you can never have too many remotes!
