Does anyone know how to make a simple flow for the following? I have an air pump for an aquarium that I want to start and then stop after 3 minutes every two hours between 05:00 and 23:00. The air pump is connected to a regular smart plug. So, for example, start at 05:00, stop at 05:03, start at 07:00, stop at 07:03, etc. I’m totally new into this with homey and flow, and got my homey bridge today 🙂 I just think it seems complicated if I have to enter all the measures manually one by one. Thanks in advance! 🙂 // Per ---

Use the Day & Time card “Every number” and for number fill in 2 hours. ---

Will probably trigger at 0h00, 2h00, 4h00, 6h00 etc… until 22h00 😉 but I guess the friends in the aquarium don’t know if the hour is even or odd… AND - Time between… THEN - Turn Plug on - Turn Plug off - Delayed with 180 seconds.
