Device Commissioning and Configuration¶

The device is commissioned using the POST /devices API as described here. For the OPUS Micropelt TRV below specific information must be used in API.

{
  ...
  "deviceType": "bidirectional",
  "eep": "A5-20-06",
  "productId": "00401000003F",

To control a TRV, a RPC command should be sent to respectetive MQTT topics. To device/{eurid}/rpc/command topic json below should be sent when a temperature change request is made.

{
  "request_id": 1,
  "eep": "a5-20-06",
  "payload": {
    "temperatureSetpoint": 35,
    "temperature": 20,
    "referenceRun": 0,
    "rfConnectionInterval": 0,
    "summerBit": 0,
    "setPointSelection": 1,
    "temperatureSelection": 1,
    "standBy": 0,
    "learnBit": 1
  }
}

Important keys are temperatureSetpoint and temperature.

temperatureSetpoint is the desired room temperature.
