KNX Dimmer

Configuration
1

Hi I have the following addresses from my dimmer:
0/0/16 Living room projectors ON 1 bit No No
0/0/17 Living room projectors dimming UP 4 bit No No
0/0/18 Living room projectors OFF 1 bit No No
0/0/19 Living room projectors dimming DOWN 4 bit No No

I have tried:

- name: "Dimmable Lounge light"
  address: "0/5/16"
  state_address: "0/5/17"
  brightness_address: "0/5/16"
  brightness_state_address: "0/5/18"

But I get on and dim but no off.
Can anyone advise?

Thanks

Hi :wave:!
Different GAs for ON and OFF are not supported by a Knx light entity. The usual way is to have a single GA using 1 or 0 payload.

I think your dimming GAs are DPT 3 - relative (start-stop) dimming. This is also not supported by HA.

Sorry Just looking further I also have :
0/5/16 Living room projectors Value 1 byte No No
0/5/17 Living room projectors Status 1 bit No No
0/5/18 Living room projectors Dimming status 1 byte No No

I can get an on and an off using the app Easy KNX via 0/0/18 but that doesnt work in HA

Thanks

Even an on and off would be good

Try:
First: brightness_address
Second: state_address
Third: brightness_state_address

And the one you can use to turn on and off as address

Many thanks for response.
If I understood correctly I have input:

    - name: "Dimmable Lounge light"
      brightness_address: "0/5/16"
      state_address: "0/5/17"
      brightness_state_address: "0/5/18" 
      address: "0/5/16"

But no joy.

You can’t use the same GA for address and brightness_address.
address requires a 1 bit GA. You talked about “0/0/18” before…

Many thanks for responding I tried as suggested below:

    - name: "Dimmable Lounge light"
      brightness_address: "0/5/16"
      state_address: "0/5/17"
      brightness_state_address: "0/5/18" 
      address: "0/0/18"

But the light then shows as unavailable
I have the following addresses available:

0/0/16 Living room projectors ON 1 bit No No
0/0/17 Living room projectors dimming UP 4 bit No No
0/0/18 Living room projectors OFF 1 bit No No
0/0/19 Living room projectors dimming DOWN 4 bit No No

0/5/16 Living room projectors Value 1 byte No No
0/5/17 Living room projectors Status 1 bit No No
0/5/18 Living room projectors Dimming status 1 byte No No

AS mentioned on another basic app 0/0/18 will turn on and off which would be fine if I can somehow use just that.

Thanks again

When you change address, a new entity will be created - as this is used for unique id. Look for the new entity.

Otherwise “unavailable” would mean you are not connected.

THank you so much It turns on and off which is all I needed. REALLY appreciate your help.
