Yeah couple of pics for the wiring would be helpful

Yeah, so i went through your posts one more time,
and i think the wiring is not right. One end of the floatswitch should go to GPIO pin (sensor) and the other end of the float switch should go to a 3.3 v or 5v power rail. You should connect a 4.7k (or 10k) resistor from the 5v- floatswitch pin to GND.

resistors & capacitors are like ball valves and unions. I would say yes, sometime i understand why we need them, sometime not. But I certainly realized that its good to have them . Follow one of the circuit i have shared. It will give extra safety (repel currents etc) for the Pi.Right before you posted this I thought to myself, "maybe I'm supposed to use a 3.3v pin instead of GND", made the switch and now it works! LOL. Jesus christ. Do i still need a resistor if I'm using a 3.3v pin?

Im glad it worked out. These things are fun , sometime small stuff can sink a lot of time, but then when it works, its rewardingThanks again, Ranjib. What a day it's been
Yes, just follow the lighting build guide, and let us know if you are stuck with anything: https://reef-pi.github.io/build-guides/lighting/Hello Ranjib,
What do I need to control kessil a80 from raspberry pi3?
I need to boost the pmw voltage to 0-10 v ?
If yes, how please?
This is very niceOk this looks better lol.

I've procrastinated and haven't built any of the electronics yet for my reef-pi, but am planning to now. I want to start with the temperature and power controllers. Can you guys look over my parts list and see if I'm missing anything and let me know what to get as far as wire, etc. I'm a complete noob when it comes to wiring electronics. (Give me a router or switch any day!)

What gauge wire and how much should I buy to wire up the receptacles?
Do I need any bread boards to connect the resistors?
Any thing else I need other than a piece of wood to mount all of this to?
I'd change the last item. Amazon has 120 cables for $6 with prime shipping. But I'd get the breadboard/wire combo.

I used 14gauge solid wire. Bought 50ft spool and still have some leftover.
Perfect, thanks!! Switched the last item and chose this wire: https://www.amazon.com/dp/B00NP1IH2E/_encoding=UTF8?coliid=I2N10QFPY7PRA3&colid=57VEC82Y59CQ&psc=1
You are right. Mechanical relays will support higher current. But I have heard solid state relays last longer due to no mechanical parts, but I have not used any of my relays enough to attest that. I have both types, they all work equally well for me, i guess my setup is so small it doesn't matter.Just my 2 cents on your parts list. I would replace the SS relay module with something like this one:
https://www.amazon.com/SainSmart-10...pID=51bZoi1iudL&preST=_SY300_QL70_&dpSrc=srch
Mechanical relays will carry more amperage, and should last longer. I'm not sure that you will ever exceed the 2A rating on the SSR, but these will give a larger safety factor.
Also, as was said by Twocorns 14 AWG is what your standard 15A house circuit is wired with, so that is what I would use.

One thing for sure the solid state relays dont make any noise, while the mechanical ones do, and you can hear click cluck as the temperature controller kicks in
Looks good to me. 14AWG minimum for 10A current load.I've procrastinated and haven't built any of the electronics yet for my reef-pi, but am planning to now.

You are absolutely right.You are probably right about lasting longer under smaller loads and the fact that there are no moving parts. I think my thought was more about possibly being near the load limit shortening the life of the SSR.
Something important to consider is the size of the tank, and the wattage of the heater (or lights) you plan on using. My tank for example has 2x 350 watt heaters which are 3A each. Those would be a problem for 2A relays.
Either one will most likely work for most people, but if you have a larger tank I would go with mechanical relays.
