Custom sensor via rest not appearing in HA

Configuration
,
1

I want to add a sensor from REST API to home assistant. I have added the following config to the sensors: array and configuration.yaml. Config validation passes, but i cant see the sensor in HA. Also I found nothing in the logs.

Anybody see what could be the probem here? The API configuration is correct, I am using the same method to get the data into Zabbix

  - platform: rest
    resource: https://192.168.120.90/redfish/v1/Chassis/1/Power
    method: GET
    headers:
      Content-Type: application/json
      Authorization: Basic xxxxxxxxxxxxx
    json_attributes_path: PowerControl[0].PowerConsumedWatts
    unit_of_measurement: 'W'
    unique_id: sensor.smc-nas_power
    name: "SMC NAS Power consumption"
    unit_of_measurement: 'W'

Is in there twice. Not sure if that is the issue or not. I think it could get confused.
