Evergrow/Reefbreeders LED 0-10v expansion dimming

[astralmind]

Random thought (and probably stupidly obvious) - I'm about to butcher my Marsaqua and realised I couldn't find any easy way to control (dim) my lights software wise (android app or portal). Have I missed something ? I used the Parabola setting in the Wizard, offseted the times for Daylight and actinic, picked start end % but.. from there on, is there a way to actually control and dim the lights ?

From what I see it looks like I'd need to re-write the code should I want to change the current intensity ? I see that from the portal it is possible to play with a Jebao in realtime for example, changing its setting and intensity so it must be possible to send values to the memory for the daylight and actinic variable ? I must be missing something..

If you're just looking to set them to a particular value, the Android app is the best way. Just long press on the value and it'll pull up an override slider.

that's exactly it! awesome, thanks.

Seems like a fairly common feature that is well hidden Not that it is super useful but still fun

So I've managed to make the dimmer work with the standard PWM (Analog in this case) channels on the RA and as expected, analog doesn't dim to 0% but that's find. What bugs me however is the high pitch whine sound that seems to be heard only at low %, I don't recall hearing that before. In fact, oddly enough, it seems like the fans are actually ramping up and down following the % dim while they were always running 100% regardless before the mod when using the pot.

Any thoughts ?

I cut the stereo cable in half to make two cables. Bare ends to the dimming module. I removed one of the dimmer knobs and put the stereo jack in its place and then soldered up a harness with some hookup wire and the 3 pin connectors. I did zero cutting to the case or original wiring.

I have the requisite connectors and was about to wire up the adapter but wanted to make sure all that was needed was the 0-10v and ground connections on the 3 pin header.

Edit: disregard; tested it out and it works Only issue I have is the 3.5mm jacks I purchased are significantly smaller than the holes for the manual dimmers. Not sure if I'm going to drill another hole or use a washer yet.

Washer is nice and simple.
