Description

Hi!
I'm currently tinkering with PJON [(pjon.org)](https://www.pjon.org/).
There are multiple options for communication, "it's just another protocol", but [SoftwareBitbang](https://www.pjon.org/SoftwareBitBang.php) over one wire got my attention there.

> It supports simplex and half-duplex asynchronous serial communication for up to 254 devices over a single wire. The maximum length of the bus can reach between 800 and 2000 meters depending on the mode used.

So you can easily do a three wire bus (PWR,GND,PJON-DATA) for your home.
