I’m the creator of NoCAN, an Arduino-compatible “wired” IoT platform for makers. NoCAN is based on CAN bus and targets applications where traditional “wireless” IoT is not optimal, due for example to signal issues or battery issues.
Basically, NoCAN features a set of powerful Arduino-compatible nodes that are controlled by a Raspberry-Pi, and that can be programmed remotely to become a sensor, an actuator or whatever you need. NoCAN already speaks MQTT, Json/REST, blynk, etc, so I was wondering if there is some interest from the community to integrate it with the home-assistant.io platform.
I am very interested myself, I am a long time Home Assistant user and I found your Kickstarter campaign when I was looking for ideas on a wired IoT network.
My use case has a few facets, first is security and network saturation. While I have a dedicated IoT vlan I am not a fan of how many wireless devices I have on my network, aside from possible congestion issues due to the amount of devices I have it also raises the noise floor considerably.
Also, that greatly increases my threat surface.
The other reason I have been looking for a solution like yours is reliability. Even with multiple access points I have coverage issues with some of my IoT devices, a wired network would be ideal to remediate that.
I am looking forward to what NoCAN could provide me.

It’s good idea. In Poland we have commersial solution (arduino and canbus extension) named Ampio.
Take a look on http://ampio.pl but protocol of canbus is closed.
