pi-power-switch

Control relay board with REST API on a Raspberry Pi

Under development - current version is a proof of concept only!

Tested with:

• Python 2.7.9
• Bottle 0.12
• gpiozero 1.4.0
• Raspberry Pi 2 running Raspbian Jessie
• Noname "Arduino 4 channel relay module board" from eBay

Features

• Control GPIO output pins with simple REST API
• One output emulates myStrom WiFi Switch API for simple integration into other scripts
• Runs as system service (see scripts/init.d)

Installation

1. Install bottle and gpiozero Python libraries:

   pip install bottle
   sudo apt install python-gpiozero
   

2. Copy this file to /home/pi

   or wherever you prefer, e.g. /usr/local/bin

3. Connect relay module board:

   • verify if relays are active high or low. Adapt Python script accordingly.
   • set BCM pin numbers in Python script

4. Install script as system service:

   if this script was not installed in /home/pi: change $DIR and $LOG_DIR in pi-power-api script.

   sudo copy ./scripts/init.d/pi-power-api /etc/init.d/
   sudo chmod 755 /etc/init.d/pi-power-api
   sudo update-rc.d pi-power-api defaults
   

5. Start daemon

   sudo service pi-power-api start
   

TODO

• Externalize hard coded values into configuration file
• Support remote GPIO
• Simple web-interface
