| | + | * SwitchBot 温湿度計を ESP32 でモニタリング [#hefa2313] |
| | + | RIGHT:&tag(SwitchBot,Meter,温湿度計,HomeAssistant,ESP32,ESPHome,BLE); |
| | + | |
| | + | [[SwitchBot の温湿度計:https://www.switchbot.jp/meter]]は、リーズナブルで家庭で使うには問題のない精度があるので、なかなか便利です。 |
| | + | |
| | + | この温湿度計は、公式の [[API (Meter BLE open API):https://github.com/OpenWonderLabs/python-host/wiki/Meter-BLE-open-API]] が公開されていて、BLE Advertisement パケットをリッスンすることで、温湿度データを取得できます。 |
| | + | |
| | + | これを、ESP32 を使い HomeAssistant で利用できるようにしました。ESP32 のファームには ESPHome を使用しています。 |

| | + | if(data.data.size() == 6) { |
| | + | float temperature = (float)(data.data[4] & 0b01111111) + ((float)(data.data[3] & 0b00001111) / 10); |
| | + | if (!(data.data[4] & 0b10000000)) { |
| | + | temperature = -temperature; |
| | + | } |
| | + | int8_t humidity= data.data[5] & 0b01111111; |
| | + | int8_t battery = data.data[2] & 0b01111111; |
| | + | int8_t rssi=x.get_rssi(); |
| | + | id(humidity0).publish_state(humidity); |
| | + | id(temperature0).publish_state(temperature); |
| | + | id(rssi0).publish_state(rssi); |
| | + | id(battery0).publish_state(battery); |
| | + | } |
| | + | } |
| | + | }} |
| | + | |
| | + | シンプルですね。カスタムコンポーネントを作るまでもないので、lambda を使いました。 |
