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

Instead of editing the config file directly, you can also update them by:

1. Click the Raspberry Pi icon in the upper left.
2. Go to Preferences>Raspberry Pi Configuration
3. On the Interfaces tab enable the necessary items

To install reef-pi:

1. On the raspberry pi, navigate to and download the latest release https://github.com/reef-pi/reef-pi/releases
2. Copy the .deb out of the downloads folder to your desired location, I moved mine into Documents.
3. Open Terminal and type

sudo dpkg -i /home/pi/Documents/reef-pi-0.3-pi3.deb

thank you, that worked like a charm. I am sure i will be bugging you all for a while since i am moving to the next step..

Thank you @Ryan115 . I'll update the guide tonight

Well i didnt know if there was a better circuit for the conversion or one thats rated more amps or not.

Just went over the install guide, nice update!

Just did a little playing around this evening, hooked up the DS18B20 thermometer controller and I can see the temperature trend on the reef-pi.
Might be a silly question, is there a place this data gets stored from everyday, if yes, how do I access it. Also on the live screen, I can't see a trend of more than 20 minutes, is that the way the app is set or am I missing something.
thanks in advance everyone.

If telemetry is enabled, then the data will be sent to adafruit.io where you can see trend of day/week/month. On the controller itself, I have set it to store last 20 values. ..so if your monitoring frequency is 1 min, you'll see last 20 min's trend, if the monitoring frequency is 5 min, you'll see last two hours trend.. these numbers (past 20 values) are obtained arbitrarily, we can definitely have more or less data if need be, or just make it configurable , etc.

Just got it to work, thanks. Currently, my temperature probe is updating every minute on Adafruit dashboard, my temperature is a whole 1.5 to 2 degrees off, any idea why this would be?
My reasoning for saying the temperature probe DS18B20 is off, I have checked the tank temperature using an analog and digital temperature probe and they both read at 78 to 78.1F, the probe reads steadily between 79 and 80, hence I believe there is something with the way I wired or probe itself.

Should not be related to wiring. Can you share a photo of the circuit.
Ds18b20 uses one wire protocol, so there is not much in circuit. Also , who is the probe vendor ? Canakit ?

I bought the probe from Amazon, do you think, "temperature controller is running in dev mode, skipping sensor reading" is the issue?
if yes, please let me know what I am doing wrong.

Devmode is on. This is fake temperature. Go to systems page , unchecked devmode. Update, and reload

Yeah that is the issue. Devmode is used to develop reef-pi on systems other than raspberry pi,so all hardware features are mocked out. Please unchecked it from the systems tab and reload reef-pi. Also, check if the temperature probe is detected correctly (unrelated to your issue, but still relevant) by

ls /sys/bus/w1/devices/

 

[AshwinRavi]

when I unchecked dev mode on systems page, and hit update and reload, it stopped reading temperature. so, I rebooted raspbian. now, I have this.

just checked, I have the probe listed

Reef pi is not running due to some error. Can you restart it and share the logs ?

sudo systemctl restart reef-pi.service

If it still does not start , remove the database, and restart , then uncheck dev mode as well as all other module you are not using, then reload

I just tried to update to 0.3 and I am also getting the same failure codes.
Reloading 0.2.1 on top and everything is running fine.

AshwinRavi, if you want to check your temp sensor in the mean time

cd /sys/bus/w1/devices
ls
cd 28-xxxx (change this to match what serial number pops up)
cat w1_slave

That should give you a t=XX.xxx, which is your temp in deg C.

thanks, yes, i tried that and I get Temp in deg C.

error logs and update after I removed the database

 

[AshwinRavi]

just unchecked everything but Temperature in system window, and reloaded the page. now, i have Temp readings and its accurate. I held it against an ice cube to check and make sure it wasn't the fake reading i was seeing before.

Any idea what was causing this? Ideally i would like to go back and start controlling more using reef-pi, my next project was to get a power controller added using relays.
