MacでIRKitとSiriを使って日立のエアコンを動かす！

Last updated at 2017-04-14Posted at 2017-04-13

Macにhomebridgeインストールまでは良かったが。。。

ワタナベ書店の記事を参考に、Macにhomebridgeをインストールしたまでは良かったけど、肝心のエアコンが動かなかったので備忘録。

赤外線信号がメーカーによって違う

IRKitは反応するものの、エアコンが赤外線信号を拾ってないぽいので、問題はそのあたりにあるだろうと予想。
我が家は日立のエアコンを使っていて、他のメーカーに比べると赤外線信号が複雑ということをIRKit購入時にWebで目にしていた。

まずは日立の赤外線信号をゲットする

IRKitの[iPhone用App](https://itunes.apple.com/jp/app/irkit%E3%82%B7%E3%83%B3%E3%83%97%E3%83%AB%E3%83%AA%E3%83%A2%E3%82%B3%E3%83%B3/id778790928?mt=8)を立ち上げ、「ボタンを追加」→「リモコン信号の学習」で、日立のエアコンのリモコンをIRKit本体に向けてON。しばらくしてIRKitのLEDが明滅したら、homebridgeを稼働させるMacのTerminalで

% curl -i "http://irkitxxxxx.local/messages/messages" -H "X-Requested-With: curl"

と叩いてやると、以下のようにえらく長い信号が帰ってくる。
※ONの後でOFFの信号もゲットすることを忘れずに。
