@mfalkvidd Good news ! Thanks for a links :)

Hi, I have a raspberry pi with Domoticz. I have all sensors, actuators etc wired to central place so don't need a radio to send data. I want use an arduino and 8xMCP23017 + ethernet shield to connect it to my network. It's possible to use mysensors without NRF radio ? It's possible to connect all sensors to mysensors ethernet gateway and send data from sensors to Domoticz without wifi nodes and relay nodes ? I don`t need any wifi nodes, relay nodes etc at this moment.
