I fundled around with some X10 units and some KaKu units at home and an Melsec Mitsubishi plc at the office
I like the PLC option best but want a more open control of the controller and I want to localize the Relais Units at 3 or 4 central points in the house
very important to me is implementing one section at a time and independent functioning of the switches (direct connecting to the relais) without an central controlling computer
So I opted for this unit ( not too expensive) which I found at the webshop of our chinese friend Ali

"8 Channel Relay Network IP Relay Web Relay Dual Control Ethernet RJ45 interface"

However no manual included in the box and only info avaiable in modern chinese . Ofcourse I can do as advced by the seller and translate it with google but..
maybe there is already knowlegde, translated manuals and advice on how to use the board on this forum.
Has anyone experience with this board and can anyone point me to a location with more info ?
