Magnetswitch smart home for various applications

I need to recognize whether the car is running or not so that I can trigger automations. In the same way, I have it so that the car recognizes whether it is plugged in or not. I find this interesting for campers. The magnet that works with USB triggers the contact switch and you have a signal that you can work with in the smart home.

I can say that when the car starts, it turns off the lights, switches off the water pump, turns off the underfloor heating and turns off the music in the living room.

When you stop and the car is off, it turns the lights on and so on.

Don't like to think about everything every time. For me, it's a huge effort if you forget something, transfer to the wheelchair and switch off, so I did everything automatically.

Why what was done?

Melt-in thread because I want to dismantle it umpteen times and self-tapping screws simply won't hold any more at some point.

New are w holes on the side. The sensor has play because not every magnet has the magnetic field in the same position, so you can slide it. Without screws to fix it, the sensor can slip and then no longer switch.

Large hole so that you can remove the sensor with your finger to change the batteries. The opening is also larger so that you can insert something to remove the sensor.

Hole for cable from the magnet.

Two-piece so that you can print without support and can easily use different magnets.

The type of switch because there is also a temperature and humidity sensor.
