Zeitgesteuerter Taster

[m.gans]

Moin

Habe einen normalen physischen Impulsgeber (Taster).

Diesen habe ich in NodeRed eingebunden.

der Taster darf erst ein True senden, nachdem er mindestens 5 Sekunden gedrückt wurde. Lässt man den Taster unter 5 Sekunden los, so soll sich die gesamte Sache abbrechen. Ein erneutes betätigen von mindestens 5 Sekunden wäre dann fällig.

Mittels Trigger Node komme ich auf halbgare Resultate.

@teemo Na die trigger Node ist schon richtig. Hast Du einen Datenpunkt der solange true sendet und dann false bist Du ihn loslässt oder sendet der Taster nur einmal true und dann nichts mehr?

Wenn der Taster während des Drückens permanent true sendet dann machst Du noch eine Filternode davor.

Du kannst das mit den Inject Nodes simulieren und so musst Du halt das Eingangssignal ggf. anpassen.

Das false Signal setzt die trigger Node zurück und es wird nichts gesendet, wenn also false innerhalb der 5s in der trigger Node ankommt.

[m.gans]

@mickym Der sendet so lange True wie gedrückt wird. Wird losgelassen, sendet der nichts mehr.

@teemo

Dann musst Du so ein Konstrukt aus 2 trigger Nodes basteln:

Wenn die true Signale - langsamer als im 250ms Bereich kommen, dann den Wert der 1. Node erhöhen.

@mickym oke. Habe es jetzt auch hinbekommen. Danke trotzdem. Gibt es eine Möglichkeit die ablaufende Trigger Zeit auf dem Dashboard anzuzeigen?

[mickym]

@teemo Nein - Du kannst höchsten mit einem Zeitverzug parallel einen Timer anzeigen, wenn Du willst.

[m.gans]

@mickym Gibt es irgendeine Möglichkeit eine ablaufende Zeit im Dashboard darzustellen?

[mickym]

@teemo Wie gesagt klar Du kannst immer einen Timer ablaufen lassen und das ausgeben. Auch mit der trigger Node - ich mach gleich einen flow.

[mickym]

@teemo So ich habe jetzt auf die schnelle einen Timer mittels function Node gemacht - weil sich das in diesem Fall anbietet.

Du kannst es aber mit intervall auch asynchron komplett programmieren oder auch über flow variablen ohne Code implementieren.

Es gibt aber auch fertige Nodes: https://flows.nodered.org/node/node-red-contrib-countdown

Oder ich habe auch in meinem Datums/Zeit Thread mal einen Timer gebastelt: https://forum.iobroker.net/topic/61256/timer-count-down-node

@mickym Kann das nicht importieren:

Achso und wie lange das runterzählt stellst Du hier ein:
