What is it?

Arduino-butler is a project for controlling RF power sockets and possible other appliances over the network. At the moment, it consists of an arduino sketch implementing a REST server that allows you to switch RF sockets. The excellent rc-switch library is used for sending RF commands.

How to use it

You'll need an arduino (I'm developing on an UNO), an ethernet shield and a 434 MHz receiver module (available e.g. on Amazon). In order to use the code, you'll have to make some adjustments:

• Adjust settings.h to set MAC and IP adresses and to configure the IO pin connecting to the receiver
• Modify the function toggle_switch in arduino-butler.ino to account for protocol and setup of your RF sockets (consult the documentation of the rc-switch library for more information on the subject).

If all goes well, your arduino will listen on the configured IP / port 80 for incoming HTTP requests. Use the endpoints /socket/X/on and /socket/X/off to toggle your RF sockets (X being the index of the socket as interpreted by toggle_switch).

Debugging

Change LOG_LEVEL in settings.h to LOG_LEVEL_LOG or LOG_LEVEL_TRACE and fire up the serial monitor.
