We have a bunch of remote controlled power sockets at the space, and wanted to control them via our space automation tools.

== Building ==

=== Hardware ===

* ESP8266
* A 433Mhz transmitter. Look at https://github.com/sui77/rc-switch/wiki/List_TransmitterReceiverModules for examples

We used a WeMos D1 mini board for the ESP8266. It's powered over USB, and provides 5V to the RF module. The Data pin of the module is connected to GPIO 4 (Pin D2), and works just fine with the 3.3V of that pin.

=== Software ===

* Arudino IDE for ESP8266
* [https://github.com/sui77/rc-switch rc-switch]
* [https://github.com/knolleary/pubsubclient pubsubclient]

== Usage ==

Send the following to the MQTT topic defined in <code>config.h</code>, e.g.<code>mumalab/room/rcsockets</code>:

<pre>type,house_code,device_code,action</pre>

with the options

* <code>type</code> - Type of RF sockets used, according to https://github.com/sui77/rc-switch/wiki/HowTo_OperateLowCostOutlets (which is missing type D). Only implemented types are &quot;a&quot; and &quot;d&quot; right now.
* <code>house_code</code> and <code>device_code</code> - Whatever is set on the socket as address
* <code>action</code> - <code>1</code> for switching on, <code>0</code> for switching off
