Home Automation

Recently, I start to use my electronics and programming skills to implement an home automation solution. For that, I use the OpenHAB2 software, that I find to be very flexible and that fits my needs.

I would like to have a wired network of sensors (pushbuttons, temperature, humidity, water level...). After research, I went to the following conclusions:

CAN4Home

So, I decide to propose my own implementation of an home automation system. Physical layer is done by a CAN bus, because transceivers are cheap and CAN bus is wired and reliable on long distances.

I used an OrangePi Zero+ (RaspberryPi-like platform) for the OpenHAB server, that is on my electric wiring box. The sensors and actuators are controlled locally using Arduino-based platform. Everything is then connected together throw a CAN-network, with MCP2515/MCP2551 as CAN-bus controller/transceiver.
