I've tried to make a mod for this myself for a while now, however the usual way of making modlets doesn't allow this and the way I used wasn't the best.
Essentially what I'm running into with builds is that if I want to have a powered door it can only be activated with one switch or motion sensor, which means that I can't for example make a garage door that will open automatically from both sides.
Now because of having done said "not best way" I know why this isn't currently a possibility, however programmatically I have seen it done in what I think is an efficient manner before.
I won't state any of it here to avoid violating rules but if TheFunPimps read this feel free to reach out.
That said I'm sure if you do decide to implement it you'll find a better way than amateur programmer me :)
And to other members of the forum, did you ever run into this problem?
A light you want to switch from multiple places, or something similar?
If so please post about it below I hope this isn't just me being petty :3
