Thanks for your help

Try this:
Code: Select all
ReefAngel.Relay.Set(Port2,(now()-3600)%43200<120);

Thanks Roberto. How to set the interval starting at 23.00?

All times are based on midnight, so I decreased 3600 seconds from it.

Hi,
That seems like a pretty arcane way to do this.
How about:
Code: Select all
ReefAngel.Relay.Set (Port2, (hour() == 11 || hour() == 23) && minute() < 2);
I think that would be simpler and is certainly more readable.

Its certainly a good way, but not the best long term and for many who do time based operations can lead to the wrong actions. Yes it is more readable, but its less flexible for many of the repeat scheduling people want to do. The way I try to explain the previous usage would be
(now() + offset) % repeat < runtime
Hope that helps clarify. Fun part of coding is coming up with different ways to accomplish things. Always good to see different ideas.
