Intro

In this post I’m going to try something a little different, I’m going to explain the process I used to control a four gang power socket with PowerShell. Now I’m only going to be sending serial commands with PowerShell as the hard work is being done by an Arduino and the “rc-switch” library but still this was a really fun project to do and one I wanted to share!

To start, you’ll need all the following items:

Bill of materials:

# Name Price Shop
1 Arduino Uno £15 Google/eBay
2 433 Mhz Transmitter and Receiver £3 eBay: search for “Arduino 433” or “RF Link kit”
3 Energenie Trailing Gang with Four Radio Controlled Surge Protected Sockets £20 https://energenie4u.co.ukwww.amazon.co.uk
4 Breadboard and a few jumper cables Google/eBay

Part 1 – Capture the RF codes for your Energenie Power Strip

To start you will need to connect up your circuit like the diagram below

Energenie-fritzingRx

This is a photo of how mine looked when completed

Energenie-PhotoRx

Like I mentioned in the intro we will be using the “rc-switch” library which can be downloaded from http://code.google.com/p/rc-switch/. Add this to your \arduino-1.0.1-windows\arduino-1.0.1\libraries\ directory and open the Arduino IDE.

Now open the “ReceiveDemo_Simple” sketch and upload this to your Arduino.

Energenie-LoadReciveSketch

Open the serial monitor, assuming everything is wired up correctly when you press the buttons on your remote the codes will appear as “Received <7Digit>  / 24bit Protocol: 1”, for example:

Energenie-COMResults

Collect each of the buttons 7 digit codes into a table so we can use them in the transmission circuit. I recommend using a table, for example:

Switch ON OFF

1

4314015

4314014

2

4314007

4314006

3

4314011

4314010

4

4314003

4314002

ALL

4314013

4314012

This concludes part 1, I have included links to the next and previous posts below to ease navigation of this blog series
