I'm new here - thanks for the indulgence I have a problem and need help. I'm looking for a way to record the switch-on time. However, it should not be a stopwatch function. Thank you for a support ein-aus-zeit.json (5.6 KB)

Hi @jannis_avstria Welcome to this forum! I'll change to German for the answer - anticipating that's easier for you to follow. Das ist der Flow, den Du gepostet hast: [image] Folgende Themen fallen mir auf: Der complete node ist überflüssig. Verbinde einfach set msg.payload mit function 1. f…

[image] jannis_avstria: I'm looking for a way to record the switch-on time. Since the button returns an 'OPEN' or ' CLOSE' when the button is flipped, you could add a switch node to test for 'OPEN' and have an 'otherwise' condition. Connect the 'OPEN' output of the switch to a change node and…

Sorry, I didn't express myself correctly. I wanted to use timestamp. if I'm not mistaken the timestamp is the system time. so i thought if i turn on and write the timestamp (ts1) and then turn off and write the timestamp (ts2) i can calculate ts2 - ts1 and get the turn on time which will currently b…

A timestamp is the current time in milliseconds since January 1st, 1970. I'm sorry, but I don't understand what you are saying. Can you lay it out step by step? I.e: the switch is turned on so I grab the current timestamp and put it in msg.startTime etc etc

Thanks for the support. I just want to set the current systemtimestamp when the switch is "close" and set a current systemtimestamp when the switch is "open". The difference would then be the duty cycle. the same by the next time you turn.

A quick google search using 'javascript calculate time duration in seconds' gives all sorts of answers. Here is a little flow with an example; [{"id":"ef115d0382c7ebd8","type":"inject","z":"7335944434544722","name":"Close","props":[{"p":"payload"},{"p":"topic","vt":"str"}],"repeat":"","crontab":"",…

Danke für die Unterstützung. Ich möchte einfach den aktuellen Systemzeitstempel setzen wenn die Schalterstellung "close" ist und einen aktuellen Systemzeitstempel setzen wenn die Schalterstellung "open" ist. Die Differenz wäre dann die Einschaltdauer. Beim nächsten Schalten dasselbe Spiel. Der Co…

Unfortunately I only have one switch that allows open and close thanks

@zenofmud 's flow was an example. This is his example with one switch (and a toggle function) [{"id":"59c3f928d7d13d71","type":"inject","z":"71622dfc02dd7a7b","name":"Switch","props":[{"p":"payload"},{"p":"topic","vt":"str"}],"repeat":"","crontab":"","once":false,"onceDelay":0.1,"topic":"","payload…
