まさかの国鉄対応。
ポキオ、異動する
いままでは京急一本で行けるオフィスだったのですが、今回異動をしましてオフィスも変わり、通勤経路に山手線に乗るというイベントが発生してしまいました。なので、ﾀﾞｧ3号を致し方なく山手線に対応させてみました。

- メインのシーケンスはNode-REDで組み立てています。
- （シーケンシャルですが）京急と山手線の運行情報をWebから取得しています
- 山手線の運行情報はYahoo!から拝借
- Global変数に、直前に表示させていた文字列を覚えておき、不要な画面書き換えを抑制
ちなみに、表示ロジックも変更。
Pythonのスクリプトの引数とその数から、よしなに情報表示してくれます。よしなに。
