I have a Homey Pro running lates firmware (v12.2.1).
I have just bought the GU10 White (3802965) and Colour (3802967) and are unable to add them to Homey. I can add them to other gateways, so the bulbs are working.
I have one Zigbee device connected to Homey and that was added without any problems.
Bulbs blink one time after adding power stating that they are ready to pair.
Homey is searching for devices to add but are unable to find the bulbs.
I have tried adding as generic Zigbee device or through the Namron app.
I have tried factory resetting the bulbs.
I have tried holding the Homey centimeters from the bulb.
Resetting the lamp and then immediately pairing to Homey. As soon as you pair the lamp with another bridge, you have to reset the lamp again before pairing to Homey.
I know, but I got the idea that after resetting all kinds of things are tried, including connecting to other bridges again. So I mentioned this just to be sure.
