light.white.level (Read white light brightness)
light.white.level: Read white light brightness
light.white.level · Channel scope · Permission Config
What it does
Reads white light brightness on this channel per device.capability.list: IPCs often use struct { mode, brightness } (table below); some bulbs use integer brightness 1–100 (light-brightness scalar) with the same propertyId light.white.level—do not force struct or the device may return DV20xx.
Request URL

Minimum permission
The administrator does not need an extra permission on a device they bound. A shared device needs the basic configuration permission. A bound sub-user does not. A sub-account needs Config. Omitting channelId on a channel-scope capability returns DV2007. Mixing device and channel in one request returns DV2008.
