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

I am thinking that a vertical line would move down the x-axis along with the time of day, and the current values would be reflected in a text box.
Mostly just to reflect where you are in your light cycle
Like this...

Got it. Let me cross check with the library I am using for charring, I’ll keep u posted

Well, since everyone is showing their power outlet builds I’ll share mine too.
The HDMI is the connection to the main Reef-Pi box. When I finish the other enclosure I'll show them side by side with all of the other sensors and stuff I have built.

How did you make this enclosure? What material is this?

I think its a project enclosure, https://www.amazon.com/dp/B06ZYCDS3Q/
Bunch of sockets:https://www.amazon.com//dp/B008J80J1A/
An hdmi brekout board: https://www.amazon.com/dp/B075Q83W5F/
A 5v ac to dc PSU: https://www.amazon.com//dp/B0140K8AXE/
Ryan would know the exact list though,

Ranjib is exactly right about how I built the power bar. Here’s a picture of the inside. It still needs to be wired, but is otherwise ready to go.

So analog ph probe is annoying to say the least.
Most recent steps have been uploading the python spi library onto the pi. And turning spi on.
attempting to use some open source python for my purpose. Nothing fancy just a lot of math lol. gives a ph reading based on a linear equation. From what ive read this is how this probe works. Now in actuality ph is logarithmic so i may need to change this. And crack open my college calc book since i havent used logs in a decade lol. So hoping linear equation works.
This was a welcome break from the wiring since I currently have no way of knowing if what i have wired works yet.
There is virtually no support for this chip online. And none whatsoever for using on a pi.
I test anything next time will be something with lots of support online lol.
Other supplies currently added to circuit:
Level shifter
10k resistor
Added $1.25

This is exactly what I expected. I had pretty much same experience with analog temperature sensors.
Thank you for sharing your learnings from this

Port is 80 with new release . If you are enabling https then it will be 443

Thanks.
Any reason you know of that the folder wouldnt be created?

I have never used Tor, so I cant say for sure. I use straight https + port forwarding.

The log for tor service looks clean, no error., reef-pi service's home directory is /var/lib/reef-pi, I dont know if this is something needs to be specified in the configuration or not.

Hey, I’m working on my build, I’ve got the box designed, power into it, my outlets wired to the relay, however when I go into add for equipment it’s giving me this error:
“{"error":"Failed to update. Error: gpio: could not find pin matching 29"}”

All jumpers are wired correctly as per the pin out on the Github site, this error occurs for all pins. The relay is jumpered on VCC/GND.

Any ideas?

I dont believe there is a GPIO 29.
Pin# 29 corresponds to GPIO5.

Thanks man, that definitely fixed it, now relay 1-5 works perfect, oddly enough 6 and 7 don’t seem to activate the relay

What Ryan has mentioned , check this guide
https://reef-pi.github.io/general-guides/electronics/
The pinout diagram indicates gpio PIN numbers (in green labels) for corresponding serial number (their position)

Cross check the wiring, check if they work if you swap the pins . You can deduce whether the relay itself is wedged or config /wiring is broken that way

No problem, this has been a source of confusion for others in the past (myself included)
Are you running the relays from a separate power supply or from the pi 5V?
Also, as Ranjib suggested, switch the control wire from working relays to isolate whether it is the relay or the connection/control pin.

 

[ReeferMadness88]

Got it sorted! Up and running it was a faulty jumper wire. Always something stupid lol I’ve pulled the wires for my PWM into the canopy for the lights now I just have to wait for snail mail from China for the digital to anolgue converters to show up, then I can crack the lights open and hopefully get them integrated. I appreciate the help today, like most things it’s a simple overlooked thing. Great community

I was also out and about today except purchasing not selling.

Red Sea star

Some snails

And 2 acro frags.

nice .

 

[ReeferMadness88]

Not sure if this is a functional issue or a bug, but I haven’t changed the pin out or anything on the temp sensor. I have A 4.7k resistor on the signal pin. It was displaying accurate temps all morning however now it just displays temps from 14:55 this after noon. Any ideas?

 

[Gareth elliott]

The temperature probe is rather finicky in my experience, picks a lot of noise. If i turn off my pi and turn back on i get periods of no readings. I wonder what vertex will use or if a digital isolator would enhance its reliability?
