Add extra parameters to the config topic like:

• unique_id

{
    "unit_of_measurement": "°C",
    "value_template": "{{ value_json.temperature }}",
    "state_topic": "homeassistant/sensor/deconz/state",
    "name": "deconz_temperature",
    "unique_id": "deconz_sensor_temperature",
    "device": {
        "identifiers": [
            "deconz_sensor"
        ],
        "name": "DeconzSensors",
