Continuing the discussion from Osram Lightify:
(Garden) lights LEDVANCE do not work and are not all recognized indeed.
Outdoor flex strip LEDVANCE SMART+ do not work (simple zigbee device) only on/off supported
Same for the LEDVANCE SMART+ White GU10 spots
On the contrary the GU10 RGBW spots do work and are being recognized
Please add them .
