# Homebridge Air Conditioner with ANAVI Infrared

[Homebridge](https://github.com/nfarina/homebridge) plugin that uses [ANAVI Infrared](http://anavi.technology/#products) to drive a “dumb” air conditioner with a unidirectional remote with power, up, and down commands.

The plugin was designed and tested on [Raspberry Pi Zero W](https://www.raspberrypi.org/products/raspberry-pi-zero-w/).

## Prerequisites

- Enable I2C.
- Enable LIRC module overlay.
- Update `/etc/lirc/lirc_options.conf` and `/etc/lirc/hardware.conf` for the hardware.
- Reboot.
- Install packages. For Raspbian Stretch:

```shell
# apt install nodejs-legacy npm lirc i2c-tools libavahi-compat-libdnssd-dev
```

- Create LIRC configuration.
- Install [Homebridge](https://github.com/nfarina/homebridge#installation).
