Raspberry Strogonanoff

A Raspberry Pi Remote Mains Switcher, to switch these

http://www.maplin.co.uk/remote-controlled-mains-sockets-5-pack-348217

with one of these

http://proto-pic.co.uk/434mhz-rf-link-transmitter/

using the awesome reverse engineering detailed here

http://www.fanjita.org/serendipity/archives/53-Interfacing-with-radio-controlled-mains-sockets-part-2.html

Installation

Requires WiringPi-Python

git clone https://github.com/WiringPi/WiringPi-Python.git
cd WiringPi-Python/
git submodule update --init
sudo apt-get install python2.7-dev python-setuptools
sudo python setup.py install

Circuit

You'll need something like this http://proto-pic.co.uk/434mhz-rf-link-transmitter/

Assuming that is the one you buy, the transmitter has 4 pins. Wire

Tx Pin Raspberry Pi Header Pin
Pin 1 GND Pin 6 0V (Ground)
Pin 2 Data in Pin 11 GPIO 0
Pin 3 Vcc Pin 2 5.0 VDC Power
Pin 4 ANT 173mm antenna wire (not on the Pi!)

where the Raspberry Pi Header Pin numbers are the little ones on the inside of the diagram below.

If you've had to read this section, please see the disclaimer below.

Running

Needs to be run as root -

sudo ./strogonanoff_sender.py --channel 1 --button 3 --gpio 0 on 

where the GPIO pin number is 0 (the default) if wired as per the table above, or otherwise the big ones on this diagram

Disclaimer

It works for me, but connecting stuff to your Raspberry Pi can destroy either end. If it does, no matter how negligent I've been, I'm sorry, but it's your problem.

Something went wrong with that request. Please try again.
