Code for PAIRING Pi-mote Energenie 4 sockets

[StuckPI]

This code is so you can PAIR 4 sockets using the pi-mote. There is an error on socket 4 OFF, until i fix that you will need alternative code at end of post to correctly control them after being paired.
Pi: Raspberry PI 2B+ Also tested on Raspberry PI 3.
OS: Jessie Lite (update May 2016)
Device: ENER002-2PI.

Pre-requisites: gpi-gpio . energenie .
Pi mote wired on jumper leads to T-Cobbler.
(Credits for the first 2 belong to energenie, who wrote the original script, I simply corrected it, and added the correct codes to add sockets 3 and 4 if you want 4 sockets controlled by a pi, as its impossible to find the code online via google (at least i found it impossible)
NOTE: socket 4 OFF is commented out, this is because for some reason its code is too close to 3, other codes will work but its a pain looking for them. In the end i managed to find enough codes to pair the devices to all 4 sockets.
Here is the code:

#import the required modules
import RPi.GPIO as GPIO

# set the pins numbering mode
GPIO.setmode(GPIO.BOARD)

# Select the GPIO pins used for the encoder K0-K3 data inputs

# Select the signal to select ASK/FSK

I then used https://pythonhosted.org/energenie/ to correctly control all 4 sockets (on and off)

Additional: I now have 8 sockets controlled by the pi, I am only learning its the best i can do for now as i couldnt find the answer i thought it should be here, because others might have the same problems with the pairing.
I discovered the pi-motes can be paired on a single pi without interfering with each other, there are just enough pin outs on the 40 to do it. (Hope it helps someone.)

The control codes for turning 4 separate remote sockets on and off are documented by Energenie both in the python script ENER002-2PI.py and in the PDF user guide - https://energenie4u.co.uk/res/pdfs/ENER314%20UM.pdf

According to those sources "1101 and 0101 socket 3 ON and OFF" and "1100 and 0100 socket 4 ON and OFF"

The PiMote board and the Energenie sockets are now supported in the gpiozero python module - http://gpiozero.readthedocs.io/en/v1.2. ... #energenie In my tests the gpiozero/Energenie combination was able to pair with my single switch to use any one of the 4 'channels' available.

I was unable to get the version of Python that I had to work properly using your script and the Pi-mote. I have been writing shell scripts for the past twenty years and thought that I could use your script as inspiration and develop my own shell script.

So I converted your code into a bash shell script and added some interactive control and also the ability to pass command line arguments. This script can be instructed to turn any socket on or off. In interactive mode the script will loop round asking for a socket number and then whether to turn it on or off. The loop is terminated when the user selects socket 0.

Arguments may be passed to the script and the screen output sent to /dev/null when automating the switching of the P-mote sockets.

e.g. ./energenie-a.sh 3 y > /dev/null

This will turn on socket 3 and dump the screen responses into /dev/null.

If anybody feels that this script would be useful I will upload it to this site.

If anybody feels that this script would be useful I will upload it to this site.

As an interested party in this thread, can I say that demo/sample code often turns out to be of value to someone at sometime in the future.

So thanks for your efforts, and I would encourage you to publish what you have done via a blog post, a github gist, or a posting to these forums.

(Since this is a Python thread, adding a shell script here might not be appropriate.)

You are quite right about a shell script not being appropriate in a Python thread. I have created a new thread in the "Projects" forum where I have published the script and the code for the web page.

Thank you for the advice.
