Attributes

Upload client-side attributes for one or more devices.

Topic: v1/gateway/attributes

{
  "Device A": {"fw_version": "1.0", "battery": 87},
  "Device B": {"fw_version": "2.1", "battery": 92}
}

Replace GATEWAY_DEVICE_ACCESS_TOKEN in the commands below with the gateway device’s access token.

mosquitto_pub -h "mqtt.thingsboard.cloud" -t "v1/gateway/attributes" -u "GATEWAY_DEVICE_ACCESS_TOKEN" -m '{"Device A":{"fw_version":"1.0","battery":87}}'

Subscribe to the response topic first, then publish the request.

{
  "id": 1,
  "device": "Device A",
  "keys": ["fw_version", "battery"],
  "client": true
}

{
  "id": 1,
  "device": "Device A",
  "keys": ["state", "level"],
  "client": false
}

Example:

The gateway keeps a single MQTT connection open per device, so use mosquitto_rr: it subscribes, publishes the request, and waits for the response over that one connection, matching the request/response pattern this API expects.

Replace GATEWAY_DEVICE_ACCESS_TOKEN in the commands below with the gateway device’s access token.

mosquitto_rr -d -q 1 -h "mqtt.thingsboard.cloud" -p 1883 -t "v1/gateway/attributes/request" -e "v1/gateway/attributes/response" -u "GATEWAY_DEVICE_ACCESS_TOKEN" -m '{"id":1,"device":"Device A","keys":["fw_version","battery"],"client":true}'

mosquitto_rr -d -q 1 -h "mqtt.thingsboard.cloud" -p 1883 -t "v1/gateway/attributes/request" -e "v1/gateway/attributes/response" -u "GATEWAY_DEVICE_ACCESS_TOKEN" -m '{"id":1,"device":"Device A","keys":["state","level"],"client":false}'

Subscribe to receive push notifications when shared attributes change for any downstream device.
