@FredericRP the first or the second soldering you made ?
You can detect ringing ?
The only useful one is the dark blue on the picture above that allows shunting the SW2.
I can not detect ring but for now that is not necessary: people can ring on the intercom then tap on “Open” in the app. It’s not as user-friendly as it could, but it’s working… until someone is able to tell me what is expecting the Nuki Opener on the yellow wire !
