I like to use store bought PIR motion sensors and have them trigger a Pam-1 relay due to their quality and being much safer. I’ve been using heks Door, Window and Push-button sketch with S_MOTION/S_DOOR. This way I only have to short one of the pins to ground.

Well today I took the multi button relay sketch and combined it with heks sketch allowing me to have multiple motions on one pro mini.

Here’s the sketch with two motions

hek,

Would it be possible if you could make a new video that's more up to date? I know that this could be asking a lot but I tried multiple times to combine sketches/examples to no avail. I presently have nodes next to each other that I would love to be able to combine them together. Also, possibly adding in how to add two of the same examples, for example two door/window sensors?

I really want to get a grasp on this and have been reading a lot but unfortunately I’m still missing something.

Either way thanks you for your video. Even though I haven’t been able to get anything working I now have a better understanding of what needs to be done.

Wanted to post it incase someone else wants to use it.
