KNX switch to call HA scenes

Configuration
1

Hello,

I am using Home Assistant in a KNX environment with Nodered KNX Ultimate. I figured out some things, where I am stuck right now is how to get a mdt Glastaster smart II to control HomeAssistant scenes.

I can of course call the scenes from the HA GUI, but I would really like to be able to call them from a switch. Any ideas how I can do that?

Thanks,

S.

From HA, use a Knx Interface Telegram device trigger or a knx_event automation trigger.

Hey farmio, thanks for the answer. Unfortunately, I am a total noob here and need at least one example to get an idea how this really works.

Would you or someone else be so kind and explain every step? I understand knx_event I think, but I do not know how I can make sure that HA really gets a telegram. In the end, I am going to configure a switch in ETS to a certain GA, and when I press the switch, the GA gets sent, and HA runs the connected scene.

Just how in the world I get that connection going I cannot fathom. Sorry for the noobiness…

I’d recommend to use the Device trigger instead of knx_event. See this video for a step by step instruction. https://youtu.be/O3p3dISvTtI
Just use a different action setup according to your needs - starting the HA scene or whatever you like.
