light.white.start (Start countdown white light)

light.white.start: Start countdown white light

light.white.start · Channel scope · Permission Config

What it does

Instant on for a countdown white-light session; configuration switch: enabled. Returned time usually comes from default countdown duration. Poll state while running. Input clientLocalTime. One invoke runs one action.

Request URL

POST https://openapi-[DataCenter].easy4ip.com/openapi/v2/device.service.invoke

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. A timeout does not mean the operation did not run.

Request parameters
