Hi I am an electronics engineer with over 28 years experience, I have done many projects with interfacing over long wires. From looking at your schematic the microcontroller would be damaged if the cable recieved a lightning strike or large ESD shock. In one of my previous jobs I designed secutiry alarm panels that had cable input runs of several hundred metres.

Hello, all you need for your project is proper calculations and it will work with no problem... need to know the wires you are using, and the rated current that passes into these wires to determine whether it will work or not. please contact me.

There is a potential risk of having affected by EMI causing false triggers and also killing the nodeMCU by backEMF due to inductance caused by the long wire. If awarded I would give you a 2 page report on how to improve this and why and would also be available on Chat. Since I am on a different timezone the initial communication may see some delay.

You must use ground connections with screen cables for low voltage sensing. Or you can add long distance sensing circuit before the switch..
