Wiz bulb "current power" is unknown

Hardware

Hi, I have some Wiz light bulbs and ZHA provides a “current power” sensor. But this sensor is always “unknown”.

In the App the power of each bulb is shown. How can I fix this?

File a bug.

I think that is normal. Wiz bulbs are Wifi, and ZHA is Zigbee.

Woops, my fault. Obviously it is not ZHA
