Help choosing equipment for my small project

[PaPiTo]

you need test.

Hi!

Everything is working.

In the end, I connected the KC directly to the alarm's backup battery, and everything works fine. The digital inputs are shorted to ground to activate.

The KC fulfills my need: the ability to arm and disarm the alarm from anywhere. Therefore, I can also know at any time whether the alarm is armed or not (in case I forget whether I armed it when I left home).

And of course, if the alarm is triggered while I'm not home, I receive a notification on my phone.

All of this is done through the Smart Life app.

Thanks for your help.

Regards
