MQTT Cover - Tilt command template is ignored

[Webbeh]

The problem

Trying to communicate with a MQTT cover actuator that supports JSON commands, I am having trouble with the "tilt" command.

The device supports payloads of this sort :

{
  "motion": 0
  "position": 50,
  "lamella": 50
}

Motion = 0 : stop
Motion = 1 : up
Motion = 2 : down

Position : send position in percent
Lamella : send tilt in percent

You can send one or more objects in the json, but you don't have to.

What does work :

• Position in percent
• Open / Close commands for position
• Tilt in percent
• Status for both tilt and position

Actuating the blinds up or down, and to a certain position works well. The tilt open/close commands are the issue. Whatever I do in the config, HASS seems to completely ignore the tilt_command_template option that I provide it, and keeps sending 100 for tilt up, and 0 for tilt down.

I also tried to change the value of tilt_opened_value and tilt_closed_value to the JSON that I want, but HASS complains that MQTT.Cover only supports integers.

Anything in the logs that might be useful for us?

Nothing in the logs.

Additional information

I keep receiving "100" or "0" in MQTT.

The status works fine, it's just the TILT commands that don't work.

Hey there @emontnemery, mind taking a look at this issue as it has been labeled with an integration (mqtt) you are listed as a code owner for? Thanks!

It seems your tilt_command_template works fine. Did you test the service call?

The Home Assistant Community forum is the place to ash for further if needed.

Actuating the blinds up or down, and to a certain position works well. The tilt open/close commands are the issue. Whatever I do in the config, HASS seems to completely ignore the tilt_command_template option that I provide it, and keeps sending 100 for tilt up, and 0 for tilt down.

I also tried to change the value of tilt_opened_value and tilt_closed_value to the JSON that I want, but HASS complains that MQTT.Cover only supports integers.

Green works.
Red doesn't.

[jbouwh]

Right, the buttons result in different service calls, and a command_template is not applied. I am preparing a fix.

[Webbeh]

I would be okay if we could just send any kind of payload with tilt_opened_value and tilt_closed_value, if that makes the fix easier.

[jbouwh]

The linked PR should fix the issues you are having now.

Hmm, my HASS isn't 100% up to date, cover.py doesn't import MqttCommandTemplate.

I adapted it a little and it does the trick.
