Pleco

License: GPL v3

Pleco is a complete fishtank controller, intended to be run on a RaspberryPI, with a relay board connected. With that hardware, it’s possible to turn on and off any AC equipment (such as lights, water pumps, etc).

Features

  • Simple appliances (100V-220V) on/off using relay controller board
  • Schedule on/off for lights, water pumps, etc

Hardware

  • Raspberry PI (any model should be compatible)
  • Relay board

Install

To install, SSH into your Raspberry PI, and run:

git clone https://github.com/dklight/pleco.git
cd pleco
pip install -r requirements.txt

Usage

CLI

For now, pleco is just a CLI script for turning on and off electrical (AC) stuff.

Each electrical appliance should be conected to a port in the relay board. Each port should be asociated to a Raspberry PI GPIO pin.

To turn a port on use the pleco_cli.py script as follows:

./pleco_cli.py --port=1 --on

To turn a port off simply use the pleco_cli.py script as follows:

./pleco_cli.py --port=1 --off

Scheduling actions

It is possible to use Cron to schedule on/off actions:

root@raspecera:/etc/cron.d# cat light_controller
# Main Lights
0 08 * * * root /usr/bin/python /usr/local/bin/pleco_cli.py --port=4 --on
    --conf=/etc/pleco.conf
0 20 * * * root /usr/bin/python /usr/local/bin/pleco_cli.py --port=4 --off
    --conf=/etc/pleco.conf

For additional help with Cron syntax use crontab.guru
