Light switch manager

Written by Jonathan Oxer for SuperHouse Automation Pty Ltd

Description

Reads digital inputs on an Arduino Mega (or compatible board with on-board Ethernet, such as a Freetronics EtherMega) to detect button presses.

When a button press is detected, the event is reported to MQTT.

Can optionally display events locally using a Freetronics 128x128 colour OLED module.

See more at http://www.superhouse.tv/

Required Libraries

  1. PubSubClient.h

  2. FTOLED.h NOTE: Only required when using the OLED display option.

Installation

  1. Change directory to Arduino's main sketchbook directory
  2. git clone https://github.com/superhouse/LightSwitchControllerMQTT.git .
  3. Start Arduino IDE.
  4. Go to File--->Sketchbook--->LightSwitchControllerMQTT

Pin Allocations

Assuming a Freetronics EtherMega or EtherDue:

2 DHT temperature / humidity sensor 3 External watchdog "pat" (output) 5 Tilt sensor input (biased high internally) 16-47 Button inputs 48 OLED CS 49 OLED DC 53 OLED reset 54-69 Button inputs

Button Mappings

Each button is connected to a digital input.

Skips 62 and 64 in east switchboard using EtherDue. I can't remember why!
