Port only on for X minutes every hour?

[agentgreen]

I had an ATO already when I bought the reefangel, so I was wondering if I could program a port to only come on for say 20 minutes every hour, or every couple of hours?

This way, if my current ATO gets stuck on, it won't flood my house!

Thanks!

Many different ways of doing, but I'd just use this:

Code: Select all

    if (minute()<=20) ReefAngel.Relay.On(Port1); else  ReefAngel.Relay.Off(Port1);

Clever.

Thanks!

Let's say you're using the same type of idea for a dosing pump, but you only want each pump run for 20 seconds 5 minutes apart once per day, would the code look like this??

Code: Select all

if (hour()==8 && minute()==0 && second()<=20) ReefAngel.Relay.On(Dosing1); else ReefAngel.Relay.Off(Dosing1);
									
if (hour()==8 && minute()==5 && second()<=20) ReefAngel.Relay.On(Dosing2); else ReefAngel.Relay.Off(Dosing2);

That works
