I've got a couple of Kevo door locks that are about to become dumb locks. Looking to replace them with something that doesn't need to call home to corporate just to function locally, which I assume means I need to set up something more substantial locally. Taking a quick look around there appear to be 4 or 5 main control systems and about as many communication protocols. Where can I learn the pros/cons/functionality of each?

Windows keeps reminding be that I have to switch to Linux if I want to keep using my computer. It's a rugged tablet from about 2011 that I still use daily for internet and some light Photoshop. Core i7 1.2 GHz, 4GB RAM, and the important part, a built-in touchscreen and Wacom digitizer. Keyboard is an external device that I don't generally have attached. I grew up on DOS, so I'm not afraid of fiddling, but I'd rather this machine just worked. Any recommendations?
