I have not tried this myself, but I don't think it works. I control hue lamps via the hue bridge and other things via the conbee (sensors etc.) I can't find lamps connected to the hue bridge with the conbee.
Can I use the Hue Essentails Android App to control my Philipps Hue lamps that are connected to the Conbee II?
The original Hue App from Philipps can only communicate with the original Hue Bridge.
The Conbee II overcomes these limitations of manufacturer-specific products in conjunction with ZHA or deConz and integrates a wide range of zigbee 3.0-based devices.
