I have build in two contacts inside the Catflap axis, so if the Catflap open more than 60 degress in direction outside contact A is closed, when Catflap open more than 60 degress in direction inside contact B is closed.
And yes, I know the RFID solution, but actual not a topic: I will use my “unsecure” solution.
I check the ZD2102, there is the option to use a second contact, but I on a german page I read the second contact will not trigger a second event, use the same “way” as the first contact (parallel switch).
But I need two different signals …
Or is the info wrong? Here is a PDF, maybe you can read is “correctly”. (Update: Link fixed, thx)
I have a Devolo Homecontact, which has a Alarm contact (tamper) and brightness.
From Alarm switch I never see a entry in log (Devolo LED goes red), and the brightness is send not very often (I thought I can use the brightness sensor as signal for the 2nd contact, connect a resistor to the brightness sensor (=verby bright=contact 2 is closed) …) (Hint: DoorContact is send immediately).
So if you you know a “normal” door contact which send quickly Alarm info I can try to use this contact outside as 2nd contact.
Or when the brightness is send in real time I can also try to use this modefied “signal” …
