Dimming lights to 0

Post by paperdesk »

My lights are dimming very low, but they still glow slightly even at 0%. I was told that the following code would take care of this, but I didn't get it to work. Can someone help?

if ( hour()>=13 && hour()<21 )
ReefAngel.PWM.SetChannel( 5, 0 );
else
ReefAngel.PWM.SetChannel( 5, PWMSlope(21,0,13,0,0,MoonPhase() ,60,0) );


And here is my current code:

ReefAngel.PWM.SetDaylight( PWMSlope(8,0,21,0,0,40,60,0) );
ReefAngel.PWM.SetActinic( PWMSlope(8,0,21,0,0,50,60,0) );

Thank you,

Ted

BTW, I did put my own times in, but still it didn't seem to work.

What drivers are they?
Does the screen show 0%?
Not all drivers are capable of turning off at 0%.

Are these the evergrow? You need to put something that says if the dimming is at 0 turn off the relays for the lights. They won't shut off at 0 by themselves.

Sorry, I forgot to post the details. Inevo is right, I have the Evergrow D120 PWM version. One light dims to about 8% the other to about 7%. After that they blink to "0%" but actually retain a very faint glow. The RA app shows they are dimmed to 0%.

I ran out of plugs on my relay box, so the lights are not powered by the RA.

Am I out of luck unless I invest in another relay box?

If I can't fix it, could the drivers be damaged by this? For now I have the lights on a basic wall timer but the timer doesn't match the lights on/off cycle perfectly so they end up "glowing" for a while before and after they are dimmed at 0% by the RA.

I dont think you can damage anything but dont take my word for it. I would set the timers/dimming schedule so that the timer shuts things off before they get to that point. I would recommend another relay box.

I was afraid this would be the answer!

Well think of all the money you saved getting evergrow lights :)

I run my large DIY light array on a separate outlet and on a little wall timer instead of off the ReefAngel. I just do it to keep another outlet on my Relay Box free for things that are more interesting than on in the morning and off in the evening.
