Domoticz

I have a question: do you think that is possible to create a domotic system based on Domoticz that works via cables? For example: i could put a Raspberry board that collects data from wired sensors in every room,and then plug all the raspberry boards via ethernet LAN to domoticz server. Is this system possible to create?

Almost every thing is possible with domoticz, so I think yes

for example see
1. WIKI Piface (contacts, relays);
2. Mysensors RS485
