rotationPercent and rotationAbsolute resets after page change or screen lock

[artistro08]

So I have a volume knob for one of my media devices

rotating them to change the volume works amazing.

But keeping that volume is an issue. Since both rotationPercent and rotationAbsolute reset their values (i'm presuming) they set the volume to 0.

If we could get the volume variable in the json area, that would be a temporary fix, as I can use the ticks to adjust.

Here's my code for reference:

{ "volume_level": {{ rotationAbsolute / 255 }} }

Hi,

i understand your wish to have access to state variables in the service call JSON. Long story short: It would be very complicated to implement and make configuration much more complex than it already is.

But there is hope:

{
  "color_temp": "{% raw %}{{ state_attr('light.living_room_ikea','color_temp') + {% endraw %}{{ ticks }}{% raw %} }}{% endraw %}"
}

Not only my plugin supports the nunjucks syntax, the home-assistant side does as well. To send (parts) of the template to homeassistant, you can use the raw option.

The above example sets the color_temp to the current (home-assistant side) value + the plugin's side ticks value. It looks confusing, but you should be able to use this to do exactly what you need :)

Entered in plugin:

{
  "color_temp": "{% raw %}{{ state_attr('light.living_room_ikea','color_temp') + {% endraw %}{{ ticks }}{% raw %} }}{% endraw %}"
}

Sent to home-assistant after non-raw values were rendered on plugin side:

{
  "color_temp": "{{ state_attr('light.living_room_ikea','color_temp') + 5 }}"
}

This is rendered again on home-assistant server side (where you can do almost everything).

That's awesome!

I feel like I'm closer, but not close enough.

I tried this:

{ "volume_level": "{% raw %}{{ state_attr('media_player.chromecastaudio6417','volume_level') + {% endraw %}{{ ticks / 100 }}{% raw %} }}{% endraw %}"}

And it's not quite working.

Nevermind, Got it working!

Code for reference:

{ "volume_level": "{% raw %}{{ state_attr('media_player.office_speakers','volume_level') + {% endraw %}{{ ticks / 100 }}{% raw %} }}{% endraw %}"}

Sorry to awaken an old thread but how do I make it so the light doesn't go off when it hits zero? My math escapes me

[artistro08]

Nevermind, figured this out too!

Using brightness_step and some if else statements made it easy.

{ "brightness_step": "{% raw %}{% if (state_attr('light.desk_key_light','brightness') + {% endraw %}{{ ticks }}{% raw %}) <= 10 %} 0{% else %} {{ {% endraw %}{{ ticks }}{% raw %} }}{% endif %}{% endraw %}"}

Thanks again for your help!
