MQTT Lights - C-Bus to MQTT to HADashboard -[Solved - PEBCAK error]

I have a Clipsal C-Bus system that I have got talking to HA via MQTT light and works great. Lights are switching on and off and the HA dashboard updates when lights are switched from the wall switch.

My config/light.yaml has been done like this -

 - platform: mqtt
    name: 'Alfresco'
    command_topic: "cbus/write/254/56/37/switch"
    state_topic: "cbus/read/254/56/37/state"
    payload_on: "ON"
    payload_off: "OFF"
    retain: true

Now across to HADashboard, I have setup my dash middle panel like this -

   widget_type: light
   title: Office Light
   icon_on: fa-lightbulb-o
   icon_off: fa-lightbulb-o
	  brightness: 100  

But no luck - I get the dreaded ā€˜Error getting state, check Java Console for detailsā€™ when the page loads.

On the HA logs -

Error executing service <ServiceCall homeassistant.turn_on: entity_id=>
Traceback (most recent call last):
  File "/usr/lib/python3.6/site-packages/homeassistant/", line 1010, in _event_to_service_call
    yield from service_handler.func(service_call)
  File "/usr/lib/python3.6/site-packages/homeassistant/components/", line 116, in async_handle_turn_service
    entity_ids = extract_entity_ids(hass, service)
  File "/usr/lib/python3.6/site-packages/homeassistant/helpers/", line 105, in extract_entity_ids
    return group.expand_entity_ids(hass, [service_ent_id])
  File "/usr/lib/python3.6/site-packages/homeassistant/components/group/", line 204, in expand_entity_ids
    domain, _ = ha.split_entity_id(entity_id)
ValueError: not enough values to unpack (expected 2, got 1)

Also tried switch, but received the same error. Any guidance from the gurus would be greatly appreciated as it will not doubt be something obvious that I am missing.


Should be entity


Only when you are staring at code for this long does the obvious get missedā€¦
Thanks aimc!
