I am still no good at the code writing, I think this will work but not sure.
Code: Select all
ReefAngel.Relay.On(Port8);
if (hour()==03 && minute()<180) ReefAngel.Relay.Off(Port8);
if (hour()==09 && minute()<180) ReefAngel.Relay.Off(Port8);
if (hour()==15 && minute()<180) ReefAngel.Relay.Off(Port8);
if (hour()==21 && minute()<180) ReefAngel.Relay.Off(Port8);
Any thoughts or suggestions? Am i totally wrong?

no.
minute() is how many minutes in an hour. So, max is 59.

Am i still off?
Code: Select all
ReefAngel.Relay.On(Port8);
if (hour()==03 && hour()<3) ReefAngel.Relay.Off(Port8);
if (hour()==09 && hour()<3) ReefAngel.Relay.Off(Port8);
if (hour()==15 && hour()<3) ReefAngel.Relay.Off(Port8);
if (hour()==21 && hour()<3) ReefAngel.Relay.Off(Port8);
If so, i may need a hint

That's going to turn port 8 off for 3 minutes at 3,9,15 and 21 hours.
This is an easy to understand code:
Code: Select all
ReefAngel.Relay.On(Port8);
if (hour()==03) ReefAngel.Relay.Off(Port8);
if (hour()==04) ReefAngel.Relay.Off(Port8);
if (hour()==05) ReefAngel.Relay.Off(Port8);
So, it would turn off for the full hour of hour 3,4 and 5.
Then you can go and repeat for the other hours you would like.
But, a more compact code that would do what you want would be:
Code: Select all
ReefAngel.Relay.Set(Port8, now()%21600<10800);
The code above would make port 8 turn on for 3 hours and off for 3 hours. Just a little bit harder to understand without some math knowledge behind it, but both would work for what you want. Different ways of coding.

So this in saying out of 21600 seconds, 10800 of those seconds the relay would be off?

Is this what it should look like in internal memory?
Code: Select all
ReefAngel.Relay.Set(Port8, now()%21600<10800);

This type of code would not use internal memory. If you wanted to be able to change any of the values, you'd have to put them in some custom memory locations. This is an advanced topic so if that's what you want we can walk you through the process. A good place to start would be to post your full code.

I can just change the code when i need it changed. I don't need to be able to change it on the app or portal. I did get it working with the code above. Thanks Roberto!
