I am putting together my pi, with a couple of boards from @Michael Lane -- I've got the goby hat and a couple of the Mars Aqua boards, and will be ordering a pH board once they're back in stock. Eventually I'll probably get to the doser, but I'm not there yet.
As of today I've got 3 temp sensors and a float switch hooked up. It's overkill to have 3 sensors, really, but I had a bunch left over from older brewing projects, and the hat has 3 ports, so what the heck -- one main tank sensor, one for the overflow box, and one for the sump. If they go out of whack, they'll tell a story -- if one of them goes out of whack by itself, it'll mean something is up with one part of the full picture. Or a bad sensor.
I also wired up that simple 2-wire float switch today, which couldn't have been simpler. There's a 4-wire connector on the hat, but you can just connect two of them to the float switch (the two on the right, skip the 2 grounds, those are for other sensors, probably optical). The reef-pi UI doesn't show it triggering, I guess the dashboard would show the triggering if it was actually hooked up to an outlet, which it isn't yet. I only have one relay for the ATO right now, and it's in use on the main tank, so I can't pull it. I have ordered another one, though. I also have some RF-controlled Etekcity outlets here that I've controlled with the pi for other projects before, so I might just use those, I'm not sure yet.
So that just leaves the lights and the ph sensor. I'd love to do salinity as well, but the probe situation on that seems to not be ready for prime-time yet, AFAICT.
I have some XLR plugs here for wiring up and daisy-chaining the lights, but I don't have the right wire here for setting them up yet. I think this is right, hopefully 26AWG is enough?
