Nature Remoをいくつも買うお金がないので、M5StickCを使ってMQTT経由でエアコンを操作できるものを作ってみました。
リモコンの信号を受信してみる
こちらの記事を参考に、エアコンのリモコンの信号を受信してみました。
M5StickC／M5Stack Fireで赤外線リモコンを作ろうと四苦八苦したのでメモ
こんなのが返ってきました。

ON/OFFそれぞれのRawデータをメモしておきます。
記事に載っている下記のコードをコメントアウトし、
irsend.sendSony(0xa90,12);
Rawデータを送る場合をコメントアウトして下記のように書き換えました。
irsend.sendRaw(rawData, 853, 38);
Node-REDを使って、MQTT経由で操作できるようにする
こちらの記事を参考に、M5stickCでMQTTブローカーを使えるようにします。
ブローカーはshiftr.ioを使いました。
