hello, i am a new user, i am doing a small project and need your help, i have rasberry node res running on it, i want to control 4 relays, 17:00 starts and stops at 22:00 to repeat every 40 seconds turns on the relay and turns off for 40 seconds and so on .

Hello, You can achieve this using only core nodes. Here is a basic example flow you can import: [image] [{"id":"b0cd614b.37f948","type":"inject","z":"d6787e23.0eb1b","name":"Off at 22:00","props":[{"p":"payload"},{"p":"topic","vt":"str"}],"repeat":"","crontab":"00 22 * * *","once":false,"onceDel…

Or maybe just a couple of trigger nodes.... [image] [{"id":"3ea0be5e.263652","type":"inject","z":"2988ea8b.bedff6","name":"start","props":[{"p":"payload"}],"repeat":"","crontab":"00 17 * * *","once":false,"onceDelay":0.1,"topic":"","payload":"","payloadType":"date","x":150,"y":120,"wires":[["9893…

Nice didn’t think of putting them in series like this before the first coffee this morning :+1:t2: The 40 / 80 combination was my first thought but than i did the switch change node combination instead.

here everything works fine but how to make the relays turn off separately let's say 2 relays then the other two and so it repeats

I don't understand the exact sequence you want at at what times so hard to guess. One way would be just to have 4 flows like above (1 per relay) and adjust the times.
