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
• rc-switch
• pubsubclient

Usage

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

type,house_code,device_code,action

with the options

• type - 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 "a" and "d" right now.
• house_code and device_code - Whatever is set on the socket as address
• action - 1 for switching on, 0 for switching off
