Raspberry Pi Garage door opener - for 4 doors and about $100 in parts

You don’t have to install anything on raspberry when you use a router. See https://www.amazon.de/lte-router/s?k=lte+router.

Of course - the Raspy could simply use the routers WIFI - but still, it would mean one more device in the garage. That’s why I will first try to get the LTE stick solution working :thinking:
