I’ve tried to integrate a knx binary sensor to an automation to trigger a live camera popup on the dashboard.
First of all, I don’t receive any state change from the binary sensor and I don’t know why.
I’ve tried lot of variants, whoch I found in other discussions here at the forum. But nothing worked so far.
If your doorbell only sends 1 (on - off, but only 1 when pressed), you can use reset_after: 1.
Or just use an event or a Knx interface device trigger. https://youtu.be/O3p3dISvTtI
Also consider updating to the latest HA version.
