MQTT hub | Missing Capability Listener target_temperature

Apps

Hi,

I’m using the MQTT hub device for thermostat function(s), receiving info from the MQTT thermostat works fine but when trying to send (config) the target temperature the following message pops-up:

I reduced the output value to a fixed number for simplicity:

{
  "measure_temperature": {
    "capability": "measure_temperature",
    "stateTopic": "thermostat1/status/number:201",
    "setTopic": "",
    "valueTemplate": "$.value",
    "outputTemplate": "",
    "displayName": "temperature"
  },
"target_temperature": {
    "capability": "target_temperature",
    "stateTopic": "thermostat1/status/number:202",
    "setTopic": "thermostat1/rpc",
    "valueTemplate": "$.value",
    "outputTemplate": "21.2", 
    "displayName": "temperature"
  },
  "measure_humidity": {
    "capability": "measure_humidity",
    "stateTopic": "thermostat1/status/number:200",
    "setTopic": "",
    "valueTemplate": "$.value",
    "outputTemplate": "",
    "displayName": "Humidity"
  },
  "onoff": {
    "capability": "onoff",
    "stateTopic": "thermostat1/status/boolean:202",
    "setTopic": "",
    "valueTemplate": "$.value",
    "outputTemplate": "",
    "displayName": ""
  }

}

Am I doing something wrong here?

I would like to end in a JSON string send, how should I approach to get the value replaced by the template value?

{ "method":"number.set","params":{"value": 20.2, "id":202, "source":"homey"} }
