Hi
I’m doing something similar here, but to heat up the outdoor spa:
If you have a constant of 3 hours for the filtration then you. An use the Scheduler device’s action card for ” Schedule ahead of time” similar to the flow sample:
Schedule 90 minutes before 11:30 and repeat on …
Now if you have formula to get the number of minutes for your filter cycle, you can put that in a BLL expression (as a tag) Math.round((your formula for filter cycle in minutes)/2)
