KNX binary_sensor significant_bit dimming control

Configuration
1

Hello all awesome people!

Before version 0.115 I used KNX binary sensor to capture DPT 3.007 dimming control from the KNX bus.
I used this to dim/brighten Z-wave lights from KNX buttons around the house.
But now when the significant_bit option has been removed from KNX binary_sensor I don’t know how to do this anymore.
Anyone have any idea on how to solve this with the 0.115 version?

Code I used before version 0.115:

binary_sensor:
  - platform: knx
    name: master_bedroom_button3_left_dim_sbit1
    state_address: '1/3/182'
    significant_bit: 1
    sync_state: false
  - platform: knx
    name: master_bedroom_button3_left_dim_sbit4
    state_address: '1/3/182'
    significant_bit: 4
    sync_state: false

  - platform: template
    sensors:
      master_bedroom_button3_left_dim_up:
        value_template: "{{ is_state('binary_sensor.master_bedroom_button3_left_dim_sbit1', 'on') and is_state('binary_sensor.master_bedroom_button3_left_dim_sbit4', 'on') }}"
      master_bedroom_button3_left_dim_down:
        value_template: "{{ is_state('binary_sensor.master_bedroom_button3_left_dim_sbit1', 'on') and is_state('binary_sensor.master_bedroom_button3_left_dim_sbit4', 'off') }}"

Try a “knx_event” instead of the binary sensor - see fire_event in https://www.home-assistant.io/integrations/knx/

Thank you @farmio for pointing me in the right direction.

Here is my solution:

Wow, nice! :+1:
You may rename the thread to “WTH is it so complicated to dimm a light from a push button?” :rofl:
