Confirmed working with
Pairing InstructionsFactory reset the light bulb (video instructions [video]). After resetting the bulb will automatically connect.
While pairing, keep the bulb close to the Zigbee gateway.
What works is to use (very) short “on”’s and a little bit longer “off’s”. Start with bulb on, then off, and then 6 “on’s”, where you kill the light as soon as the bulb shows signs of turning on.
