It is not my project and I do not know these guys. But it looks kind of interresting
It still requires to pull another wire alongside mains power which means this is not interesting for existing installations.
@chrode thank you very much for sharing our project!
@Spaceman_Spiff Indeed, GetWired is not really intended to be used in existing installations. Our intention was to offer some open source & hardware alternative for home automation enthusiasts wanting to build wired systems in new or renovated buildings. Right now they rather do not have a lot propositions to choose from.
So, if you would like such a proposition to come into existence, please share or support our project!
In case of any questions, please feel free to ask me.
