Troubleshoot bind and offline

Codes below come from bindDevice and Return codes. This page does not invent extra codes.

Device already bound

Code	Meaning	Next step
`DV1003`	Already bound to the current account	Do not bind again. Query with Paged device detail.
`DV1029`	Device already bound	Same.
`DV1001`	Bound to another account	Unbind there, or use another device.

See Return codes · DV.

Wrong security code

DV1005 — verification code error. Recheck the code rules on bindDevice: auth-set password, 6-digit label code, or empty. Optional encryptCode must follow that page’s AES rule.

Unsupported device or firmware

DV1002 — device does not exist: verify the serial number.

A new device or a just-upgraded device may need the client SDK bind flow, not HTTP alone. Build a mobile app. Probe: Pre-bind information.

DV1008 — bind count limit. Unbind extras with unBindDevice. Daily quota: Interface call limits.

Device offline

After a successful bind, Online status (device.status.get) reports connectivity. DV1011 means the device is not bound — bind first.

Offline is not a bind-code by itself. Confirm power, network, and that the serial appears in Paged device detail.

Token or permission failure

Code	Where
`TK1002`	Expired administrator token. accessToken
`SN1005`	Reused `nonce` within 5 minutes. Development specification
`OP1003`	Invalid `openid` or policy on a sub-account call. Set up a sub-account
