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

<<edit>>It was me, my bad, it's working.

For some reason if I pull a wire for the relay it'll still show a change within Vera. I can turn them on and off and they'll show up as if they were turned on and off. Before if I pulled a wire to the relays vera wouldn't show any changes.

Thank you so much rejoe2 for not just giving me the answers but by pushing me to do it myself. You pointed me to where I needed to be and I thank you for that.

Now you got me wanting to learn even more.

@rejoe2 It's working

Although I'm not sure if this part makes sense?

@rejoe2 I hope that this answers your question. I use Vera as my home controller and tried multiple times turning (sometimes randomly) on and off both relays without any misses as soon as Vera allowed me. Meaning, Vera won’t let you instantly turn a device on and then off or vise versa.

Do you think I’ll be ok the way it is or should I keep working on this project?

This is where I'm currently at, it seems to be working really well. Thanks rejoe2

@rejoe2 Just so I know that I’m not heading down the wrong path and wasting everyone’s time, I should be looking into the use of millis correct?

@rejoe2 I listened to what you said and then went back over it, it's working much better now. What you said "why things are solved the way they are" made me stand back for a moment. I do Maintenance for a living and work on everything from HVAC, boilers, Kitchen equipment to hanging drywall. There's always one thing I always tell myself when troubleshooting something, what's the sequence of operation. Well I'm not to savvy with writing code although the same principles applies. Maybe I just needed someone to tell me that, I don't know.

Anyways, thank you

I updated the sketch I posted in my last post with the changes I made.
