Request URL

POST https://openapi-[DataCenter].easy4ip.com/openapi/v2/device.property.get

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.

Request parameters

Name	Type	Required	Description
`token`	String	yes	Administrator, sub-user, or sub-account accessToken
`deviceId`	String	yes	Device serial number
`productId`	String	no	Optional. If sent and it does not match the device model → `DV2009`
`channelId`	String	yes	Channel ID; `"0"` is common on IPCs
`properties`	Array	yes	`["light.alert.linkageEvents"]`
