I wrote this plugin as a wrapper around mdhiggins ESP8266-HTTP-IR-Blaster to control my Hampton Bay Ceiling fan. This particular fan uses a 303Mhz RF Remote control. 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 303Mhz RF Transmitter module.

To source the 303Mhz transmitter module, I sacrificed a Hampton Bay remote, and removed the 303Mhz SAW Resonator from the transmitter module. I then on a 315Mhz Transmitter module, removed the 315Mhz SAW Resonator and replaced it with the 303Mhz SAW Resonator. Creating my own 303Mhz Transmitter module.

1. sudo npm install -g homebridge-hampton-bay

Example config.json:

{
 "platform": "HBay",
 "devices": [{
   "lightName": "Ceiling Two",
   "fanName": "Fan Two",
   "irBlaster": "ESP_8695EC.local",
   "remote_code": "0000",
   "out": 3
   },
   {
   "lightName": "Ceiling One",
   "fanName": "Fan One",
   "irBlaster": "ESP_8695EC.local",
   "remote_code": "1000",
   "out": 3
   }]
 }

• platform - This must be "HBay"
• name - Name of the device ( or fanname / lightname )
• irBlaster - Name or ip address of your IRBlaster Device
• remote_code - This is the 4 Bit unique code for your fan controlled by the dip switches. 0 is switch UP and 1 is switch down.

• dimmable - Is the light dimmable, defaults to false
• light - Does the fan support a light, defaults to true
• out - out setting for IR Blaster, defaults to 1
• fanName - Name for fan device
• lightName - Name for light device

This is the dip switches on your control module.
