arduino-rc-control

Introduction

This project is an attempt at creating a simple home automation solution using just a few remote controlled plugs and a NanoESP with a bunch of sensors/senders. On top of that I had to find a replacement for the electronic of a capacitive touch switch in my furniture. That way, a few lamps and a garden fountain can be switched on and off.

Control...

• ... different sets of plugs and other radio controlled equipment using the standard 433 MHz remote control.
• ... any number of actors using a capacitive touch sensor
• ... any number of actors using a simple HTTP request and/or iOS app (soon)

Note: This is my first arduino project. I assume that C++ "constant correctness" does not work properly, so I almost completely removed const modifiers in the code.

Open issues:

• write desctructors for cleaning up heap space (even though some things are most probably never being disposed of any way)
• improve reliability when switching actors with the various input commands

• maybe add a small capacitor to capactive touch sensor input

• add iOS app

Components

• 1 breadboard
• 1 NanoESP Wifi module
• 1 10 MOhm resistor
• 1 capacitive touch sensor
• 1 sender and 1 receiver for 433 MHz remote commands Amazon

Setup

Wire everything up as in this diagram:

Used libraries

• Fabian Kainkas NanoESP library
• Suat Özgürs RC Switch
• Paul Stoffregens Capacitive sensor library

How to customize

• switch on receiver debug output using RC_DEBUG_OUTPUT switch and collect codes using remote control
• define unused codes for group switching using the same method
• put actors and groups in GroupBundle.cpp file
• modify the JSON definition in the index variable to reflect your configuration (if you want to create a dynamic app that is)
• create a passwords.h file as in the example below

Example passwords.hfile:

#ifndef PASSWORDS_H
#define PASSWORDS_H

#define SSID "myWifiSsid"
#define PASSWORD "mySuperSecureWifiPassword"

#endif

Using the codes on your gadge that have been unused so far (different house codes for example), groups of actors can be defined. If your wifi connection has been established successfully you should be able to switch your groups using a browser or even curl using the following simple requests (where 10 is one of the group's IDs):

curl http://<arduino-ip>?id=10\&state=on
curl http://<arduino-ip>?id=10\&state=off
