Following some years of playing with X10, and taking the opportunity of adding some cabling infrastructure whilst tackling the kitchen, I opted for Idratek for my home automation.
I added a connection box, to make it easier to connect up circuits later in an upstairs bedroom.
In the kitchen, a PLH-001 module senses temperature, humidity and light, incorporates a PIR, and has two digital inputs, one of which is connected to a magnetic door switch to sense whether the kitchen door is open or closed.
The Idratek network is controlled by a PC (I’m using a netbook) in Node 0. You’ll also spot a temperature/humidity sensor (THS-001) that will later control the adjacent fan.
