PLC-/Home Automation -Control System

This diagram illustrate my Home Automation Centre. The idea is to use isolated RS485 networks – no power – to control actuators and sensors. Power will be entered by through RS-X adapters I will draft later. I am a bit undecided on Ethernet/Wifi as this also can be sorted through Raspberry PI. The one thing I do not like with the PI is the SD (TF) card as this is its weakest point regarding reliability. GSM is available low cost and needed for dial-up solutions. The Serial Flash act as a disk. This is only an early idea draft, so lets see where we land.
