Running a series

Hello,

I’ve installed system to manage my irrigation system. Now I want to have a virtual device or something similar which can do the following:

start irrigation circle no. 1
let it run for x minutes
stop irrigation circle no. 1
start irrigation circle no. 2
let it run for x minutes
stop irrigation circle no. 2
start irrigation circle no. 3
let it run for x minutes
stop irrigation circle no. 3
etc. …

The time each circle must run must be defined by a variable. Do you have an idea to start/ stop such series?

Best regards
