homebridge-fantasia

Fantasia Viper fan plugin for Homebridge.

Fantasia is a trademark owned by Fantasia Distribution Ltd.

This plugin was developed for a Fantasia Viper ceiling fan that uses a TR32A 433.92MHz remote control. It may work with other fans that similarly use a Holtek HT12E encoder to drive an R433A 433.92MHz SAW Resonator.

Installation

1. Connect a 433.92MHz transmitter to the computer (see partlist and wiring guide below).
2. Install pilight by following the instructions at: https://manual.pilight.org/installation.html
3. Configure pilight to match the wiring of the 433.92MHz transmitter (see example below).
4. Install this plugin using: npm install -g homebridge-fantasia
5. Edit config.json and add a Fantasia accessory for each fan to be controlled (see example below).
6. Run Homebridge.

Partlist

• Raspberry Pi 2 Model B
• Raspberry Pi NOOBS Micro SD Card
• GorillaPi Raspberry Pi Case
• FS1000A 433.92MHz transmitter
• Female-Female Jumper Breadboard Wire

Alternative small form factor computers (e.g. other Raspberry Pi models or Arduino) or 433.92MHz ASK/OOK transmitters may also be suitable.

Wiring

Connect the FS1000A 433.92MHz transmitter to the Raspberry Pi 2 Model B GPIO header J8:

FS1000A pin	Raspberry Pi pin
GND	Pin 6 (Ground)
DATA	Pin 12 (GPIO 1)
VCC	Pin 4 (5V Power)

(Ignore the misleading ATAD silkscreen lettering on the FS1000A; the middle pin is DATA.)

Solder an antenna to the hole in the corner of the FS1000A board (not the small hole near the ANT silkscreen). This can be a simple straight piece of wire: 69.24cm (wavelength), 34.6cm (half wavelength), or 17.3cm (quarter wavelength). However, a coil loaded antenna is likely to give better results.

Example /etc/pilight/config.json

{
    "devices": {},
    "rules": {},
    "gui": {},
    "settings": {
        "log-level": 6,
        "pid-file": "/var/run/pilight.pid",
        "log-file": "/var/log/pilight.log",
        "standalone": 0,
        "port": 5000,
        "webserver-enable": 1,
        "webserver-root": "/usr/local/share/pilight/webgui",
        "webserver-http-port": 5001,
        "webserver-https-port": 5002,
        "webserver-cache": 1,
        "whitelist": "",
        "gpio-platform": "raspberrypi2"
    },
    "hardware": {
        "433gpio": {
            "sender": 1,
            "receiver": -1
        }
    },
    "registry": {
        "webserver": {
            "ssl": {
                "certificate": {
                    "location": "/etc/pilight/pilight.pem"
                }
            }
        },
        "pilight": {
            "version": {
                "current": "8.1.4"
            }
        }
    }
}

The essential changes to the default configuration are:

• Change gpio-platform to raspberrypi2 specifying the GPIO hardware platform being used.
• In the hardware section add 433gpio configuration to specify the GPIO used to drive the FS1000A 433.92MHz transmitter. Note that pilight use the Wiring Pi GPIO numbering scheme (not the BCM GPIO or physical header pin numbering scheme).

Example config.json

{
    "accessories":
    [{
        "accessory":    "Fantasia",
        "name":         "Bedroom Fan",
        "address":      [0, 1, 0, 1],
        "host":         "localhost",
        "port":         5001
    }]
}

The address should be set to match the code switch within the remote control and receiver. Four values are required, corresponding to switch 1 through switch 4. Use 0 if the switch is towards the numbers 1234, and 1 if it is towards the ON DIP text.

Multiple accessories can be added to control different fans. They must be each given a unique name and address.

The host and port specify how to reach the pilight daemon. They can be omitted if pilight is running on port 5000 on the same machine as this plugin.

Notes

This plugin is transmit-only; it does not monitor the fan's original remote control, so the status within HomeKit may not match the fan's actual state.

The current version of this plugin only supports fan speed control. It does not support reversing the direction or control of the light.
