I have bought from a local vendor here in Norway some GU10 bulbs - (GL-S-006P) 5W GU10 LED Spotlight Pro that I wanted to use with my Aeotec Hub (formerly Smartthings hub) through Zigbee.
The bulb is added and can be controlled with driver Zigbee light Multifunction Mc, but I cannot get below 2700K, according to Gledopto website and the local vendor (Nordic LED) it should be possible to get down to 2200K.
The local vendor is stating that this bulb is not tested or compatible with mye Aeotec Zigbee hub, is this correct ?
I have a lot of similar bulbs from IKEA, and all go down to 2200K, but they are unfortunately discontinued and not being sold anymore
You can try to use SmartThings Edge Driver Builder
and change GU10 bulb profile to color-temp-bulb-2200K-6500K (this is not color profile only color temperature) I think that your bulb is also color bulb.
Maybe this is better profile rgbw-bulb-2200K-6500K
I have the “Zigbee switch” installed and tried it, it gives me less options and still same problem - i camnot edit drivers, i am not that good at this - sorry
