What controller are you using (optional)?
Open Source Software
“Nice looking bulb and has B22 base (which is why we ordered it) however it doesn't work with the Elelabs Zigbee controller and Openhab. The association worked reasonably well (after I allowed insecure joins) and the device came online but then fairly rapidly went offline. Commands were ignored and the device never worked. Tradfri bulbs work fine in the same location so it isn't a range or controller issue. Vesternet have agreed to take it back and even paid for the return shipping for which I thank them.”
