Thanks I will no doubt need help on this, quick question, does the reef pi work with wi-fi relay switches like the Sonoff 4ch pro if i flashed it with ESPEasy or other firmware?Godspeed. Let us know if you need any help
From our experience, 10v pwm almost always work where 0-10 v analog is expected. Last time we checked one of the commercial controller using oscillioscope it was generating 10v pwm and then passed it through a LPF.
That said, it should be possible to generate o-10v analog signal as well using a DAC, its just I didnt encounter the need for it. If someone hits this roadblock, we can revisit
No. reef-pi uses mechanical or solid state relays directly to control electrical outlets. You have to get the relay and electrical receptacles and wire them up... Example can be found here : https://reef-pi.github.io/build-guides/power/Th

Get which one ? If you are going for 10 v pwm , get pca9685 breakout board from adafruit (reef pi already has code ready and tested for this ). If you are going for 0-10 v analog, get mcp4725 DAC board, we have to write the code for this , should be easy. You need couple a 10k, 1k resistor and an non diode (pn2222a) for each channel. I think your lighthas two channel , so two of eachWhats the best way to get this? I need this for the marsaqua.

If you want to control them independently, you need 6 of each, if you want to daisy chain (and if its possible) only 2Im not sure yet if its 0-10v analog or not. The lights are setup to run on the bluefish controller. Its 0-10v.
So i have three lights. Will that require 6 channels?
Awesome! I ordered the stuff for it.If you want to control them independently, you need 6 of each, if you want to daisy chain (and if its possible) only 2
Raspberry pi to pca9685 can be found here: https://learn.adafruit.com/adafruit-16-channel-servo-driver-with-raspberry-pi?view=allAwesome! I ordered the stuff for it.
I want to control the lights all together. So 2 channels will be ok.
Is there a drawing for me to go by?
Nah.. for all practical purpose, a 10v linear regulator is not a must have. I have personally tested with straight 12 v pwm, and reef-pi allows you to set a minimum and maximum threshold. This helps in avoiding higher (in case you dont have a regulator) or lower voltage (Kessil would blink in voltages lower than 3). Albeit throwing a linear regulator will make it better..so they show a voltage regulator and a different transistor in that diagram. does that matter? I ordered the pn2222a ones.
most npn transistor would work including pn2222a , 3904s etc..so they show a voltage regulator and a different transistor in that diagram. does that matter? I ordered the pn2222a ones.
Brad will you please write down steps? I will be doing this shortly.so they show a voltage regulator and a different transistor in that diagram. does that matter? I ordered the pn2222a ones.

You have the pi3? Why you need the usb cable?Good for you. My pi, ps, and jumpers came in today but I am waiting on my usb to ttl cable before i can load anything.
Yes, pi3. I thought I needed it. To connect to my computer so I could start the initiation process of the pi and load reef-piYou have the pi3? Why you need the usb cable?
Na you got a sd card right?Yes, pi3. I thought I needed it. To connect to my computer so I could start the initiation process of the pi and load reef-pi
Monitor does not have an hdmi input ?I see. I have to use my computer...no tv in the office. Multiple ways to do the same thing
