Entities with a UNIQUE_ID are needed to add a area

[Martijn Hoogenbosch]

With entities without a unique_id it is not possible to add these to a area. I have added unique_id's for all devices. So you can copy/paste it:

  - platform: mqtt
    name: "solarmanpv_station_generationPower"
    state_topic: "solarmanpv/station/generationPower"
    unique_id: "generatedPower"
    unit_of_measurement: "Wh"
    device_class: energy
    state_class: measurement

  - platform: mqtt
    name: "solarmanpv_inverter"
    unique_id: "solarmanpv_inverter"
    state_topic: "solarmanpv/inverter/deviceState"
    json_attributes_topic: "solarmanpv/inverter/attributes"
    
  - platform: mqtt
    name: "solarmanpv_logger"
    unique_id: "solarmanpv_logger"
    state_topic: "solarmanpv/logger/deviceState"
    json_attributes_topic: "solarmanpv/logger/attributes"

  - platform: template
    sensors:
      solarmanpv_inverter_device_state:
        unique_id: "inverter_device_state"
        value_template: >-
          {% set mapper =  {
              '1' : 'Online',
              '2' : 'Failure',
              '3' : 'Offline'} %}
          {% set state =  states.sensor.solarmanpv_inverter.state %}
          {{ mapper[state] if state in mapper else 'Unknown' }}
         
  - platform: template
    sensors:
      solarmanpv_logger_device_state:
        unique_id: "logger_device_state"
        value_template: >-
          {% set mapper =  {
              '1' : 'Online',
              '2' : 'Failure',
              '3' : 'Offline'} %}
          {% set state =  states.sensor.solarmanpv_logger.state %}
          {{ mapper[state] if state in mapper else 'Unknown' }}
