homebridge-rf-fan-remote Plugin

I wrote this plugin as a wrapper around mdhiggins ESP8266-HTTP-IR-Blaster to control my GE Ceiling fan. This particular fan uses a 315Mhz RF Remote control with the Model FAN61T-4SP. To use this plugin, you need to build this ESP8266 based IR Blaster device https://github.com/mdhiggins/ESP8266-HTTP-IR-Blaster, except you need to substitute the LED with a 315Mhz RF Transmitter module.

configuration

Example config.json:

}

  "name": "Master",
  "irBlaster": "ESP_869815",
  "remote_code": "1011100101100100",
  "summer": true
}

Required settings

• accessory - This must be "RFRemote"
• name - Name of the device
• irBlaster - Hostname or ip address of your irBlaster device
• remote_code - This is the 16 Bit unique code for your fan.

Optional settings

• summer - Is the fan in summer mode, defaults to true

Finding remote code for your remote / fan

To find the remote code for fan, I used an RTL_SDR and rtl_433.

Code/rtl_433-master/build/src/rtl_433 -f 314938000 -a

[03] {26} 17 2c 8f 80 : 00010111 00101100 10001111 10

remote_code starts at bit 4, and is 16 bits long. In the example the remote_code is 10111 00101100 100
