reef-pi

Hi all, I have been working on a little bit with humidity and Room temperature sensing with Reef-PI So and I want to share what I have so fare. One of the key point with my selection was that this has to be cheap while strait forward to set up. The SHT20 is a logical choice as the price is...

Hi all, I am in the process of crashing my first Aquarium controller. I have ordered a few parts and have a few Arduino laying around too. Reef-Pi is my preferred route although I am more experienced with the Arduinos and the C programming than Python. I have a case for the pi4b which has a...

Hello everyone! I've just started to set-up Reef-Pi on my raspberry Model B, Rev. 2 to use it as a hydroponics control system. But I'm struggling at the beginning already. I've been through defining my output on GPIO24 and used it for my test device. But when I turn it on or off, my LED...

Hey Guys, I'm new to the forum and a "legacy" hobbyist. I shut down my last saltwater aquarium more than 10 years ago in Brazil. But now that I'm leaving in US and with all the pandemic-stress I decided to go back to the Reef world with a nano. I started a Fluval Evo XII with standard...

Hey Everyone, How Does Reef Pi's timers react to power failures? I have set my co2 up with the following timer. If I lose power before a state change, and regain it after, Will the state change be ignored? For example, if the power turns off at 11:55, then comes back at 12:05, will the co2...

Hey Guys, I am working on a project that can measure how much dissolved co2 is in my aquarium. I have overcome a few of the major obstacles, but I have hit a bit of a wall. Has anyone done this? I am using henry's law to figure it out, if that means anything to anyone here. My current problem...

Hey everyone, I am working on a diy ph-prob for a reef-pi unit. According to the online guide I need a barrel adaptor and some kind of ph-circuit. By the looks of it, this has both built in, but I have never made one of these before. Can someone tell me if this will connect to my Raspberry-pi...

Hi all, I'm trying to modify my light configuration using the reef-pi HTTP API. I am able to authenticate and read data as shown here. The trouble starts when I try to use the command curl -X POST -b cookie.txt -d '{"id": "11", "channels":{"0":{"profile":{"config":{"start":"13:00:00"}}}}}' -D...

Has anyone done comparisons between the Robo-Tank pH circuit and other measuring methods? It seems likely that it would depend on the probe being used, but I'm curious if anyone has tested it or just has some general observations to share. Maybe @robsworld78 would be willing to share some...

Hey Guys, I am hooking up a reef Pi system. I have an low res LCD screen that I would like to have scroll information about my tank. It’s maybe 16x150pixels things like the temperature, what equipment is on, that kind of thing. Does reef Pi have the option for this?

Welcome to the world's greatest giveaway. :D ;Woot :eek: This is exclusive to R2R, it's open worldwide you can only win it here. The prize is a fully assembled Robo-Tank aquarium controller that runs on the reef-pi software, it has a value of $170 USD, you get what's in the image below. To be...

I set up my 1st intended reef tank in November of '18. I decided to go with a 150 gallon because water parameters are supposed to be more stable and I love fish too so I could have a wider selection with a 5' tank. I realized shortly after setting up this tank that my attempt at a budget build...

After a discussion with @Ranjib, we have decided to open a separate thread for the discussion around the reef-pi User Interface (UI). This thread is for suggesting UI features / upgrades reef-pi users would like to see in reef-pi. Requesting / suggesting a feature here is not going to be a...

Roughly 5 years ago I started messing with the idea of using Arduinos to do some tank control / automation. I was successful to the stage of being able to detect temp & control relays. No big deal, pretty easy etc. Same thing with other stuff - controlling relays / outlets with timers, based...

I’m making a PCB board I think I have it done still checking it. SDA1, SCL1, TXD, RXD will use jumper wires to make the connections, for PH probes one in the calcium reactor one sump. PMW0, PMW1 will use jumpers to make the connections for the dosing pump motors, this way if I want to use them...

I'm building a system based on Reef-Pi (thanks to @Ranjib and @theatrus ) that will be using a customized enclosure. Does anyone here at R2R know of any ways to make good dry-transfer decals (white text/graphics) that will adhere to ABS plastic? My enclosure is the boring "computer beige"...

After doing a lot of reading (the main reef-pi thread is pretty big, and the reef-pi pico thread is growing), I've decided I'm going to take the plunge and build myself a reef-pi controller. Mine will be a bit unique, however. I've been in the hobby for about 6 years, and already have...

I control my 2 small aquariums (one 40 gal fresh, one 15 gal nano reef) with a combination of Home Assistant (which also takes care of my apartment), Reef-Pi, and Motioneye. I wanted the tanks to mirror specific locations as much as possible. For example, I’m querying various sites to get daily...

Hey everyone! Here is another #reef-pi build for anyone interested in following :D My build will consist of @Ranjib reef-pi (of course) and I will also be using the HAT and PWM module from @wykat . I only have a laptop so I couldn't do the standard raspberry pi set up with a mouse and keyboard...

Well here we go again! This tanks occupants have been around since 2013 when it started out as a 10 gallon nano. The tank was upgraded to a 29 and then after a move it was downsized to a 14 gallon cube. The cube has been running for almost 3 years and is a softie only tank. Mushrooms, Xenia...
