reef-pi :: An opensource reef tank controller based on Raspberry Pi.

that doser looks sweet man. I plan on getting one in my system as I get there. I just wrapped up phase 2 of my system

@Erica-Renee got it all set up and running, thank you. Think that will do me for a little while, due to move house in the next couple of weeks. Gives me chance to build this properly. Hope all goes well with everyone.

@Ranjib I have to ask for help yet again! I'm starting to feel disheartened here. Setting aside the issue I have been having with the rpi pwm which is on a pi3 that I am using as a testing platform for a complete controller. I also have a pi-zero that I use strictly to run my Kessils over my tank. Now that setup is not working. It is running 1.3 and has the PCA9685 board and the dimming circuit. Suddenly it is refusing to show the "lighting" tab. This happened a couple of weeks ago and I removed and replaced reef-pi and it came back. Now I have R&R several times and nothing is working, no errors, just no tab and no control of the lights. What if the breakout board died, would reef-pi refuse to display the controls under that failure?

Edit: I just got the first error in the logs.

Jul 09 15:28:30 Reef-Pi reef-pi[216]: 2018/07/09 15:28:30 ERROR: Failed to initi alize lighting subsystem
Jul 09 15:28:30 Reef-Pi reef-pi[216]: 2018/07/09 15:28:30 ERROR: Failed to load lighting sub-system. Error: remote I/O error

if the pca9685 board is not detected, then reef-pi will not load lighting tab, since its must have for dimming.
You can verify if pca9685 is loaded using i2c-detect command

sudo i2cdetect -y 1

Check if pca9685 board is working.

Ok, that was what I was thinking. From perusing the .pdf I am assuming that I need to install "i2c-tools" as the terminal returns
"sudo: i2cdetect: command not found".

I2C on Pi

1. Run sudo raspi-config .
2. Use the down arrow to select 9 Advanced Options.
3. Arrow down to A7 I2C .
4. Select yes when it asks you to enable I2C.
5. Also select yes when it tasks about automatically loading the kernel module.
6. Use the right arrow to select the <Finish> button.
7. Select yes when it asks to reboot.

you can also do this from gui... pi configuration i forget what tab thou.. Easily found

Thank you. I2C was already enabled everything was running fine, than it became intermittent, now has stopped.

After installing the i2c-tools, I'm finding that there are no addresses listed, so I'm under the impression that the breakout board is not functioning properly.

Time to bring out the multi-meter and start checking Wiring ,connections and the servo board ..

Yay me! LOL

The thing is 2. x is beta software. a lot of changes were made in the code and being worked out.. You can go back to 1.5 (I think was the latest actual release ) and wait out until 2x final release are at least to a pre RELEASE State...

Nah it's to late now. I came the the realisation this morning when one of my filters wasn't running a small glitch in the code and it you dont notice it in time you could lose £1000's of stock. it's not worth the risk. Don't get me wrong I'm glad I tried it and think that you guys on here are brilliant with help and ideas, but I'm just not code savvy enough to keep up dating the program and putting all the equipment, timers, outlets, in lets and pins into the program. I cant even find the file with the settings in to copy it.
So its gone all back in their boxes and going to post them on eBay on Sunday night.

Hi, Firstly Thank you so much for writing such a great open source Reef application, i have seen a few attempts before but nothing ever got near this, this is awesome allready!

Is there anyway to change the password without deleting the database and starting again? I have somehow managed to change my reef-pi password in the gui (not sure how) and now i do not know what it is, below is from chrome after i login to reef-pi (password challenge screen never used to appear before)

Many thanks

I want to understand all of this so badly. I want to contribute. But...

I know the feeling. It's a little intimidating at first. Lucky for me, I'm an IT guy and have some background with coding and Linux/Pi stuff. The whole wiring thing is over my head, but I just dove in, read every post in this thread, and watched a ton of Youtube videos on how to solder, use breadboards.... I'm figuring it out! It's a fun project!

I'm a Civils guy. Getting my head around this electronics and Linux and Pi stuff is a huge departure from building roads and Bridges and pipelines.

Roads= Wires and PCB Traces...

Bridges= Resisters,Capacitors. Diods and The like
Pipeline= Voltage, Amps , and so on..

Its really not that much different..

Oddly enough, I’ve never tried to dip items in Plasti Dip, only used the spray. I’m impressed, easy to do and looks solid. These are four “Waterproof” temp probes that are metal, with heat shrink. Now they have a coating of rubberized plastic too.

Us "older" people remember when Plasti Dip was only available as a dip. LOL

Do you remember going to the tar pits, Sneaking around and Fighting off the Raptors to to the pits to dip your Sensor probes?

Yea Me to

 

[philshel]

LOL, not quite but I do remember having to build my state of the art "wet-dry" filters out of glass strips silicone together just like I read about in FAMA magazine.

This is cool :-)
My bare steel probes are still working smooth, no rust yet.
