Get and Set Brightness

[EdDickens]

I have a Wiz light configured in HA using this integration. I can turn it on/off and set the brightness using the standard “Light” card in Lovelace so it seems I have it set up correctly.

What I’m trying to setup is the ability to use an IR remote to toggle the light on/off and be able to set the brightness level. I have an ESP01 with an IR receiver and have it configured to capture IR codes to trigger different actions.

So far it can successfully toggle the light on/off using the following:

binary_sensor:
  - platform: remote_receiver
    name: "Fan Lights"
    on_release:
      homeassistant.service:
        service: light.toggle
        data:
          entity_id: light.livingroom_fanlight_1
    filters:
      - delayed_off: 100ms
    pioneer:
      rc_code_1: 0x0045

What I can’t figure out is how to set the brightness. I’d like to use 2 different buttons on the remote to increase/decrease the brightness by 5% steps per button press. I know the ‘Light’ integration has a ‘brightness’ property that can be used to set the brightness, but to inc/dec the current level by 5 I would first need to know what the current level is and that’s where I’m stuck.

How do I get the current brightness value and how then would I add/subtract 5 and send that as the new level?

Thanks
