Ok, so you are using the opensource ph board. This will not work on 2.4 and it requires 3.0 onwards. Support for this driver was done recently and its scheduled to be available for public release later this year. You can use the 3.0 testing builds to use the ph board but calibration is still not supported via the UI yet. @Michael Lane is working on this (calibration support via UI), but its not ready yet
I have not tried this but from what I understand you can treat it as a water level sensor since it give 0/1 input, and if the solenoid valve is controlled by a relay or outlet then its straight forward. Just use ATO ui to control a valve based on leak sensor input
As of now, it supports ph (and orp, but not tested yet), water level (float sensor and photoelectric sensors), temperature sensors.
Thank you Ranjib so this one least not my fault.Could not believe i am so dang can not install that.Am running reef-pi 3.0.0-pre-alpha-2-pi3.deb
Thank you Michael installed the PH and working good,i try to read Ranjib post.
HiHello All, bear with me ive never programmed anything before let alone a raspberry (Reef) -Pi.
Im using a Raspberry Pi zero W running version 2.4
I thought i configured everything correctly following the directions but during testing i could not get the testjack / PWM to work. the first test worked and i can turn the led on and off, but when trying to add the test jack it will not let me set to rpi it gives me the " {"error":"failed to update.Error: write/sys/class/pwm/pwmchip0/period: invalid argument"} | HTTP 500 " error. and nothing happens when i try to test the jack.
i think that im running the wrong package for pi zero but when i tried to install that package it says cannot access archive.
now i also noticed that when i follow the pins on the instructions that i got the led to turn on and off with nothing happens for the 2nd test but when i place the leads in what my info card says is the GPIO 18 & 19 pins on my pi zero W the led is on (although dim) even if the reef-pi is off. im not sure what any of this means o_O .
another side note when i try to enable the notification and the pca options, all of a sudden i cant connect to the reef pi through my macbook it says "site cant be reached" but if i stop and start the reef pi service again it fixes it.
Here is the setup when it worked for the first test, the errors shown right now, and the end of my config.txt file if it helps.
Please Help a noob!
And thanks to Ranjib and all of you for helping to create such an awesome and fun alternative to expensive controllers! Ive always wanted to get into coding and electronic builds and this seemed like the perfect opportunity to get my feet wet!

There’s lot of things to unpack here. Let’s tackle them one by one . But before everything , thank you for considering reef-pi. Your detailed posts help us making the software bit better for everyone else.Hello All, bear with me ive never programmed anything before let alone a raspberry (Reef) -Pi.

Been playing with the 3d printer a lot recently . Here is my first take at 3.0 ato unit.
The controller itself is bare bone , consist of just pi zero and an audio jack (similar to temperature controller)
Audio jack is used to hook up a floatswitch
This unit will be powered by micro USB port , so no extra power related circuit .
Planning to use peristaltic pump for adding water. It will be plugged into the Kasa smart powerstrip
This unit be powered directly using a 12v adapter (plugged into the smart outlet).
The onboard potentio meter allows adjusting the peristaltic pump speed. There’s a mechanical switch for manually turning it on/off.
There are notches to easily mount the units
Overall I’m excited to build these sleek units. I am little concerned about the smart plug performance , but we’ll see, it’s big advantage over the adj powerstrip , with less work involved and having manual overrides and current monitoring is really nice addition
I’m using the ones from adafruit . I bet they are very similar if not same
Hey Ranjib, thank you for putting all the time into creating it and constantly trying to improve it as well as helping us less technically inclined!
If you have a multi meter then check voltage at the other end of the jumper thats connected to the pwm pins. The download link is correct and should work.Hey Ranjib, thank you for putting all the time into creating it and constantly trying to improve it as well as helping us less technically inclined!
When I tried @Alaa suggestion i didnt get the error code but nothing happens when i adjust the light levels for the LED etc. I tried changing the pins i was using and reversing the power and negative and still couldnt get the LED to light up.
here is the setup currently and settings.
Actually looking at the pin layout im wondering if i messed up and am looking at the board upside down? i believe im atleast trying to use the right pins. 18/19 highlighted in the below picture.
and for the download i was trying to see if i was typing the code wrong so was trying a few different versions. Will this code work for Pi Zero W or should i use a different package?
Also how would i uninstall reef pi and try to reinstall ? I did reboot after pwm line and a bunch of times since trying to figure out how to get it to work ;Shamefullyembarrased
- wget -c https://github.com/reef-pi/reef-pi/releases/download/2.4/reef-pi-2.4-pi0.deb
- sudo dpkg -i reef-pi-2.4-pi0.deb
sudo apt-get remove -y —purge reef-pi
