Method: HTTP post

Return value format: json
Method: HTTP post

{ 
    "deviceid": "", 
    "data": {
        "switch": "on", 
        "brightness": 30,
        "mode": 0,
        "brightmin": 10, 
        "brightmax": 255
    } 
 }

Note:

• To adjust the brightness of the light, the light must be “on”, so if send a Dimmble API request with “switch”: “off”, it will report “400” error as operation failed.
• The “mode” parameter is used for APP development to define different modes with specific brightness, and sync the modes content of the device when sharing the device operation to others.
  For instance:
  The APP of the developer defines two modes (mode 1: brightness=5; mode 2: brightness=50) that the device can reach a specific brightness by buttons, the “mode” parameter provides the way to sync the device mode for all shared users.
• The value of brightmin should be less than brightmax.

Method: HTTP post

    "data": { } 
 }

Empty object, no attribute is required.

The following failure codes are added to the error field of the response body:
– 500: The operation failed and the device has errors. For example, the device ID or API Key error which is not authenticated by the vendor’s OTA unlock service;
– 503: The operation failed and the device is not able to request the vendor’s OTA unlock service. For example, the device is not connected to WiFi, the device is not connected to the Internet, the manufacturer’s OTA unlock service is down, etc.

Method: HTTP post

    "deviceid": "", 
    "data": {
        "downloadUrl": "http://192.168.1.184/ota/new_rom.bin",

    } 
 }

The following failure codes are added to the error field of the response body:
– 403: The operation failed and the OTA function was not unlocked. The interface “3.2.6 OTA function unlocking” must be successfully called first.
– 408: The operation failed and the pre-download firmware timed out. You can try to call this interface again after optimizing the network environment or increasing the network speed.
– 413: The operation failed and the request body size is too large. The size of the new OTA firmware exceeds the firmware size limit allowed by the device.
– 424: The operation failed and the firmware could not be downloaded. The URL address is unreachable (IP address is unreachable, HTTP protocol is unreachable, firmware does not exist, server does not support Range request header, etc.)
– 471: The operation failed and the firmware integrity check failed. The SHA256 checksum of the downloaded new firmware does not match the value of the request body’s sha256sum field. Restarting the device will cause bricking issue.

Note:

• The maximum firmware size is 508KB.
• The SPI flash read mode must be DOUT.
