What else do I need to make it work?

Every setup needs a Raspberry Pi, a Micro SD card, & a power source. After that, it’s up to you which sensors & equipment to add! The included manual makes picking out sensors simple.

You can use a Raspberry Pi Zero W, Pi 2, Pi 3, Pi 3B+, & the new Pi 4. The Zero W is the cheapest option & is what I personally use. All you have to do is download the Leviathan Reef-Pi setup to the SD card, plug it into the Raspberry Pi, plug the Raspberry Pi into Leviathan, & then plug in your power! If you don’t want to deal with setting Reef-Pi up, I also sell Raspberry Pi kits that come with the software pre-configured & ready to go.

Does Leviathan work in Canada/UK/EU/Australia/ etc?

Yes! The Leviathan board solves the issue of various voltages & outlets by using GPIO outputs attached to a relay card. You are able to power any outputs up to 250V using most relay cards available.

Leviathan is in use in multiple countries around the world including the U.K., Australia, Vietnam, Germany, Japan, & more!

Does Leviathan have instructions/ steps to follow?

It does!

It covers everything you need to know to start with the bare $10 board & build it up to the full advanced saltwater package! Parts lists, where to use which parts, tips I've learned through experience, & more are neatly organized into a single document with convenient links.

Will Leviathan work with my LED lights?

Leviathan can turn any lights on & off on a schedule using the equipment control feature! LEDs, T5s, Metal halide, it doesn't matter, as long as it plugs into an outlet, Leviathan can control its power.

However, the LED dimming feature uses a 10V PWM signal that may not be compatible with every light out of the box. That being said, if you're willing to make some small modifications, Leviathan can control a huge variety of lights on the market!

Some of the most popular LEDs, like the Kessil A160 & 360, use 10V PWM control & have an easy to access control port. You just run your wire from Leviathan to the light, plug it in, & you're good to go.

Some cheaper LEDs, like the Mars Aqua boxes, use 10V analog control & may not have an accessible port. But there's a solution to both problems! Michael Lane sells 10V PWM converters on Tindie that take the 10V PWM signal & convert it to a 10V analog signal instead. It's a simple, robust design that works great!

Unfortunately, without having a lab filled with every LED light fixture on the market, I simply can't guarantee Leviathan will be compatible with your lights if I haven't personally tested them. As far as I'm aware, most lights use either a 10V PWM or analog control signal, but I'm sure there are some oddballs out there that don't play nicely with the standard.

If you have any questions, definitely message me & I'll see what info I can find for you! But most light manufacturers don't publish their control method, because they want you to buy their super expensive controller.
