Question

Hello!
I have had several KingArt Q4s running with Espurna in Home Assistant for months. But it only indicates when it is "open" or "closed". If it stops in another position, it does not indicate its position (%).

  cover:
    - name: "Persiana Salón"
      device_class: shutter
      command_topic: "PersianaSalon/curtain/set"
      position_topic: "PersianaSalon/curtain"
      set_position_topic: "PersianaSalon/curtain/set"
      state_topic: "PersianaSalon/curtain"
      qos: 0
      retain: false
      payload_open: "0"
      payload_close: "100"
      payload_stop: "pause"
      position_open: 0
      position_closed: 100      
      state_open: "open"
      state_opening: "opening"
      state_closed: "close"
      state_stopped: "closing"
      state_closing: "stop" 
      optimistic: true

Something to do with the HA config? Kingart hw does indeed report on / off / pause, but we only ever send out 0...100 value

espurna/code/espurna/curtain_kingart.cpp

Lines 318 to 326 in 238dc13

	//Update last position and transmit to MQTT (GUI is at the end)
	if(_curtain_position != CURTAIN_POSITION_UNKNOWN && _curtain_last_position != _curtain_position) {
	_curtain_last_position = _curtain_position;
	#if MQTT_SUPPORT
	const String pos = String(_curtain_last_position);
	mqttSend(MQTT_TOPIC_CURTAIN, pos.c_str());
	#endif // MQTT_SUPPORT
	}

Also note that incoming payload is also limited to on / off / pause / numeric-value

espurna/code/espurna/curtain_kingart.cpp

Lines 358 to 368 in 238dc13

	if (t.equals(MQTT_TOPIC_CURTAIN)) {
	if (payload == "pause") {
	_KACurtainSet(CURTAIN_BUTTON_PAUSE);
	} else if (payload == "on") {
	_KACurtainSet(CURTAIN_BUTTON_OPEN);
	} else if (payload == "off") {
	_KACurtainSet(CURTAIN_BUTTON_CLOSE);
	} else {
	_curtain_position_set = payload.toString().toInt();
	_KACurtainSet(CURTAIN_BUTTON_UNKNOWN, _curtain_position_set);
	}

Thank you! But that's where I miss the truth... The HA configuration is the one pasted above, I think it's fine, right?
Yes, I can say that if I indicate position on the HA card (from 0 to 100), it does respond to that position and registers that it has been open or closed (depending on its last move).
So, I can't see the % position in HA?
Another question I have is: Why does HA appear as unknown in the registry until you make a move?

Thank you!!!

Another question I have is: Why does HA appear as unknown in the registry until you make a move?

We publish <DEVICE>/status topic as last-will-and-testament aka lwt, which tracks mqtt broker connection status of the device. <DEVICE>/curtain tracks percentage

availability:
  - topic: "PersianaSalon/status"
payload_available: "1"
payload_not_available: "0"

<DEVICE>/curtain only publishes numeric value, it would never get 'state' payload as described here.

      state_topic: "PersianaSalon/curtain"
      state_open: "open"
      state_opening: "opening"
      state_closed: "close"
      state_stopped: "closing"
      state_closing: "stop" 

WebUI does indeed show the status, but MQTT publish is missing in current implementation. Not sure what would be the correct solution here, though. Either publish special .json {state: "opening", position: 50} or have something like <DEVICE>/curtain_state

So, I can't see the % position in HA?

I am not actively using HA, just testing it with your configuration atm.
Don't see it either 🤷 , so I would only assume this is how the default widget is intended to work. Maybe some template magic / separate widget reading entity status can solve this.

With this configuration (configuration.yaml), I only get the status "Open/Closed".
How could I get the numeric value that I do see being output in mqtt?:
