[Solved] How to unlock door with a Wheel ?

[burge4150]

I'm just here to reaffirm:

SetEntityConnectionStateChangeCallback("string entity name", "function name");

Whenever a valve changes state (from all the way off to all the way on, etc) it will trigger this function. I would remove the callback or put a check in the function to make sure it can't be repeated because that'll cause issues.
