netatmo apiを利用してTemperatureを取得したので、自分の備忘として。
phpとpythonでデータ取得を試してみた。
phpでは、battery_vpの取得方法がわからん。
pythonでは、WeatherStationが複数ある場合、個々の取得方法がわからん。
今回は、1拠点のバッテリー数値の取得は、pythonで行い、温度はphpを使った。
netatmoのModule1が外部温度センサーに割り当てられbattery_vpがある。
この数値がイマイチよくわからない。
/*for raingauge and outdoor module*/
class NABatteryLevelModule
{
/* Battery range: 6000 … 3600 */
const BATTERY_LEVEL_0 = 5500;/*full*/
const BATTERY_LEVEL_1 = 5000;/*high*/
const BATTERY_LEVEL_2 = 4500;/*medium*/
const BATTERY_LEVEL_3 = 4000;/*low*/
/* below 4000: very low */
}
のように書かれているので、cactiでThresholdsを設定する。
値は、Warnigを4100、Alertを4500とした。

if(isset($device['favorite']) && $device['favorite'])

printDevices($users, "User's weather stations");

}
?>;
バッテリーデータを取得するのは、こんな感じで調整した。
print ($module['battery_vp'])."\n";
netatmo.shでデータ取得
netatmo.sh

上に書いたソースを元に試行錯誤の結果このようなグラフで妥協した。
温度データは取得出来ているのだが、グラフが結構途切れてしまう。
