ESP8266 project enabling MQTT control for a Hampton Bay fan with a wireless receiver. Wireless communication is performed with a CC1101 wireless transceiver operating at 303 MHz.
This will also monitor for Hampton Bay RF signals so the state will stay in sync even if the original remote is used to control the fan.
Fan control is not limited to a single dip switch setting, so up to 16 fans can be controlled with one ESP8266.
This project uses the following libraries that are available through the Arduino IDE
- SmartRC-CC1101-Driver-Lib by LSatan
- rc-switch by sui77
- PubSubClient by Nick O'Leary
- ESP8266 development board (Tested with a NodeMCU v2 and a D1 Mini)
- CC1101 wireless transceiver
- Wiring info can be found in the SmartRC-CC1101-Driver-Lib readme
Change the WIFI_* and MQTT_* definitions in the sketch to match your network settings before uploading to the ESP.
By default, the state/command topics will be
- Fan on/off (payload
ONorOFF)home/hamptonbay/<fan_id>/on/statehome/hamptonbay/<fan_id>/on/set
- Fan speed (payload
low,medium, orhigh)home/hamptonbay/<fan_id>/speed/statehome/hamptonbay/<fan_id>/speed/set
- Light on/off (payload
ONorOFF)home/hamptonbay/<fan_id>/light/statehome/hamptonbay/<fan_id>/light/set
fan_id is a 4-digit binary number determined by the dip switch settings on the transmitter/receiver where up = 1 and down = 0. For example, the dip setting:
| 1 | 2 | 3 | 4 |
|---|---|---|---|
| ↑ | ↓ | ↓ | ↓ |
...corresponds to a fan ID of 1000
To use this in Home Assistant as an MQTT Fan and MQTT Light, I'm using this config
fan:
- platform: mqtt
name: "Bedroom Fan"
state_topic: "home/hamptonbay/1000/on/state"
command_topic: "home/hamptonbay/1000/on/set"
speed_state_topic: "home/hamptonbay/1000/speed/state"
speed_command_topic: "home/hamptonbay/1000/speed/set"
speeds:
- low
- medium
- high
light:
- platform: mqtt
name: "Bedroom Fan Light"
state_topic: "home/hamptonbay/1000/light/state"
command_topic: "home/hamptonbay/1000/light/set"
