In my eyes, the ideal rotocol would be one that fits, but doesn't need any router at all. While not excatly that, lora , a long range(kilometers) low power/cost protocol, seems like the right choice. Just find the right model for personal deployment some open routers(similar to wifi) and let nodes seek those open nodes , and we all win.
But i'm probably missing something here, since i haven't heard of anybody doing this. I wonder what ?
Dimmers need a few bits, probably 8+ for decent control. Waiting a few seconds for a light to dim would be rather annoying. Doing RGB effects would be even slower. Ovens need at least 10 for a decent temperature range. Authenticating a door lock would require at least 128 bits one way, and another 128 the other; 30 seconds would be way too long for that purpose. Plus, you need to take into account addressing, a protocol for the type of message, and other aspects in order to route commands to the proper node. 10 bits per second just isn't going to cut it.
