Quite strange this one. I have a Philips Hue hub and some Ledvance warm bulbs (AC23684-TW). I was able to pair it successfully to the hub and am able to to see the entity in HA.
Here is the strange part. I cannot turn it on/off via the Philips hue app nor HA gui. However, if the light is on, I can control the temperature via the app and HA gui. Using a zigbee coordinator does work, but I think mine recently broke. Hoping to use the Philips hue hub to get my lights back up.
