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

It needs more gadgetry! And where is your little helper/director? ;)

He is busy dis-assembling the layout :-)

The rain boot is on for no particular reason other than his wish :-/

This is my CPU and memory usage with reef-pi and Pi Cam Control running at the same time. It is recording video 24/7.

Those 1.65 cpu utilization spikes are not good. I would not recommend running any critical monitoring system in such cpu starved system, if it’s persistent

No, it kept getting the cannot find executable problem.

I think if you can get streaming video working it would be pretty useful but the thing is who is going to have reef-pi in a position to live stream the tank and control everything? Right now I just have pi cam control running alongside reef-pi and it’s working fine. It is web based so it may be easier just to integrate pi cam control into reef-pi. It was easy to install too. You would just need to load http://loacalhost/min.php in reef-pi.

My Pi Zero is inside the light so I can have the camera come out and point downwards but I think most people are not doing it this way and the reef-pi box is probably hiding behind somewhere.

I like these tanks! Looks nice! Good way to hide the controller too!

Nice workspace, so was the pca9685 100 and zero percent bug fix in the code I identified?

That one and more.. there was frequency bug (not sure if that only on 3.0x or 2.x as well) .. here are the relevant changes (some housecleaning changes are in them as well)

and

Very nice tank. The left tank has an anemone? This light is not too bright for the pico? I worry some corals will bleach.. definitely shrooms

When they are that age, disassembly is ALOT more fun than assembly!

Always working on something just like his papa!

I have a mushroom but it's under the top coral shelf. The light is at 25% on the dinural cycle so it's not at full(25%) for very long.

CLI returning null is ok and as expected . It means it’s working

ok, so what's the next step?

 

[DirtDiggler2823]

Null is ok . That’s not errror, you should see some text with cookie details in the cookie.txt file

I have that cookies.txt file on my pi now. I also added the other files to the top of the pi directory.

 

[Ranjib]

now run the calibration

curl -X POST -d @calibration.json -b cookie.txt  http://192.168/api/phprobes/1/calibrate

 

[DirtDiggler2823]

now run the calibration

curl -X POST -d @calibration.json -b cookie.txt  http://192.168/api/phprobes/1/calibrate

Still no joy on running the calibration.

I see two different IPs, 192.168.3.187 and 192.168.3.229 , and only one of them is working 192.168.3.187 . Which one is correct? Lets not try both and test with only one . I notice 127.0.0.1 is working as well. These are all good signs. It means the API calls are wrong, lets fix that,
Can you share the content of the calibration file, it seems it has some bad data

cat calibration.json

Once the data is validated (i can audit it for you, just share it here), here is the command (change username/password)

curl -X POST -d '{"user":"....", "password":"..."}'  -c cookie.txt  http://127.0.0.1/auth/signin
curl -X POST -d @calibration.json -b cookie.txt  http://127.0.0.1/api/phprobes/1/calibrate

x.x.3.187 is the reef-pi, and 127.0.0.1 is local host from the reef-pi. x.x.3.229 is my PC.

This is what's in the calibration file

Hello friends,
I have just published two set of releases with few bug fixes, namely
- Disable ATO pump when alert level is breached
- Light charts on dashboard in auto-mode
- 0 & 100% pwm behavior when using pca9685 mnodules
The 2.4 release is a stable public release, and will not impact any existing 2.x installation, while the 3.0.0-alpha-2 is a pre-release not thoroughly field tested, but provides all the 3.0 intended features (ph driver, calibration, multiple pca9685 etc etc).

Releases can be found here: https://github.com/reef-pi/reef-pi/releases/

Just loaded 2.4 and all works, pwm bug gone!
Lighting graphs now appear!

Now to save my 2.4 database just in case and load 3.0 again! If that tests out good, time to get a ph probe on the way!!!

Great job!!!

If you have saved the dB you had with 3.0 prereleases , you can use it with the new 3.0 prerelease without any issue . It should work out as well

How do you wire the uln2803 to these boards?
Especially in refernce to the vcc and gnd?

 

[DirtDiggler2823]

Along with my pounding my head against the keyboard trying to get this pH probe calibrated, my reef is coming along.
