Hi there ! Once again I'm asking for your support ! I need to trigger an alarm with a blink function but not the typical blink (x sec ON - x sec OFF) but with different On and Off time (x sec ON - y sec OFF) I've found the "Blinking a LED on Raspberry PI" flow from IgnacioRubio witch work just fin…

Hi Nico, Here is a what I've built, this is based on a bit of searching around that I found. [{"id":"16c2553d.aac89b","type":"rpi-gpio out","z":"881975da.a3c468","name":"15-Sw1 LED","pin":"15","set":true,"level":"0","freq":"","out":"out","x":1430,"y":360,"wires":[]},{"id":"28425e06.f2483a","type"…

You can do this with just two trigger nodes if you like [{"id":"c21f81fa.7ccbf","type":"inject","z":"a992b717.c41468","name":"","topic":"","payload":"stop","payloadType":"str","repeat":"","crontab":"","once":false,"onceDelay":0.1,"x":170,"y":900,"wires":[["bb39e73d.60c5b8"]]},{"id":"bb39e73d.60c5b8…

If there is no way that's ok I'll deal with it but that would be nice :slight_smile: T…

If you would be happy with a fixed total period (on time plus off time) then node-red-contrib-timeprop would do this for you. Set up the total cycle time in the node and then pass it the ratio on/off time you want (between 0 and 1) and it will provide the result you can feed to the LED.

Here's the downloaded file, though I think DCJ has fixed the error. flows.json (2.9 KB)
