Apagando

Simple Smart Switch for lights.

Apagando means Turning off in Spanish. I named it this because inpired by Sombra in Overwatch. Their ultimate voiceline is "¡Apagando las luces!" which means "Turning off the lights".

Hardware requirements

I use Onion Omega 2 Plus to make this.

• Onion Omega 2 Plus.
• 2 relay switch.
• 3 way light switch (for manually control).

My setup like this.

Software requirements

$ opkg install python-light python-pip pyOnionGpio
$ pip install -r requirements.txt
# Run apagando on boot
$ ln -sf $PWD/start.sh /etc/rc.d/S99apagando

Configuration

I connect two relay switch to GPIO 0 and 1. I planned to connect place small switch next to 3 way switch to synchronize 3 way switch's state. It works like an XOR gate, So you can turn on the light even when Apagando malfunctioning. And apagando returns The light's status for status REST API.

3 way switch	Relay switch	The light
on	on	off
on	off	on
off	on	on
off	off	off

Edit .env to configuration

# Relay's GPIO ports.
RELAY0=17  # Red LED for testing.
RELAY1=15  # Blue LED for testing.

# Physical switch's GPIO ports.
SWITCH0=2
SWITCH1=3
# Or don't set SWITH#n for disable 3 way switch.
