Flow Windows
Das Ergebnis dieses Flows im Dashboard:
Der RPC Event Node wird so konfiguriert, dass er alle Events von Geräten, in deren Kanal-Namen die Zeichenkette Fenster vorkommt und bei denen eine Änderung des Wertes des STATE Datenpunktes erfolgt ist ausgibt. Als Topic wird der Kanal-Name (channelName) ausgegeben, dies wird später verwendet um die Liste der offenen Fenster zu erzeugen.
Der Statistic Node zählt die Anzahl offener Fenster und erzeugt ein Array in msg.topics das die jeweiligen Kanal-Namen beinhaltet. Damit nur geöffnete Fenster gezählt werden muss die Option Values auf exclude falsy gesetzt werden.
Ein Function Node verbindet dass Array mit den Kanal-Namen der offenen Fenster zu einem Komma-getrennten String und entfernt die Zeichenkette Fenster aus dieser Liste.
msg.list = msg.topics
.join(', ')
.replace(/Fenster /g, '');
return msg;Zu guter Letzt wird ein Dashboard Template Node verwendet um die Anzahl und Liste der offenen Fenster anzuzeigen.
