As long as the macro checks somehow that there is an override flag for the feeding is done let’s say 1 hour ago it would work. I can do this in phyton for sure. There’s more than one way to achieve the same.

You should be able to change the color in the main tab for whatever the graph is for. If it's pH go to pH tab and you can change color.
The pH errors could be due to I2C issues, the more devices connected the more likely issues will happen. Try slowing the baud rate down by adding the following line to the config.txt file in the boot folder on the Pi SD card. I recommend everyone does this even if no issues.
dtparam=i2c_arm_baudrate=10000
This will set the speed to 10 khz instead of 100 khz and hopefully cure things.

Hi Matevz, (or anyone who can answer) I assume someone answered your question, "What do I do with the 3.3v coming out of the driver?", but I couldn't find any. I have the same light and would like to control from reef-pi, did you get this to work?
Also I only have one light so I think I can just go straight out of the pi to the pwm on the light, instead of using a hat? If so, then I just run the pwm and ground from the light straight to the pi pwm and ground? Thanks
If you check with volt meter you should get no voltage on 3.3v wire, it's expecting 3.3v. @GaryE uses same light, at least same driver and powered the 3.3v from the PI. Two posts in a row explain.
reef-pi :: An opensource reef tank controller based on Raspberry Pi.
Confirmed.. Connected directly to the JST connector plugged in here with 3.3v from the pi, ground and PWM0 on the pca9685 and setup the driver and jack as normal.. Am able to control the brightness of this light via PWM from reef-pi. Also, as seen in the photo, I connected directly to the board...

You won't need a hat, the two PWM pins on Pi will work fine, remember to enable them in the Pi settings.

Hi all
I’m having some troubles in my reef pi setup, help would be appreciated
1-pH reading problem
As you can see I may have issues in my reef tank but pH reading of 22-24 is not compatible with aquatic life, the issue started after I calibrated my pH probe (I mentioned in a previous post) when I started having low readings from the tank (7.4-7.7) but proper reading from reference solution, I was advised it was mostly my tank pH that was low, however after retesting several times and having tank pH 8-8.1 I recalibrated my pH probe the then when added to the tank the readings were 22-24 while reading the calibration fluid properly.
I tried erasing stuck data using a previous post (running python script)
sudo wget -c https://robo-tank.ca/Robo-Tank_pH_Script.zip
python Robo-Tank_pH_Script.py
I entered R but got query failed
How do I recalibrate my pH properly and get all bad data from the system, if I save the reefpi database and then fresh install will it work
2- API usage
I’m trying to setup reefpi with home assistant, I had luck using MQTT, however I’m stuck with API
I’m trying to control a pump with rest platform
This is what I have in my sensors.yaml
Now the first rest order worked fine for a while then I started getting not authorized, though I updated the reefpi cookie, The second one never worked I always get invalid body on as per attached pic
this is what i get from my reef pi API docs
I’m having some troubles in my reef pi setup, help would be appreciated

Sorry I thought you could access with raspi-config but instead you need to edit the config.txt file in /boot/ directory.
Add the following line at the bottom.
dtoverlay=pwm-2chan
You can use the following to edit on Pi, might have to restart Pi after.
sudo nano /boot/config.txt
Hi, for the pH issue can you try the python script again but disable the pH in reef-pi first. If it's trying to read and you type in R you can get query failed.Hi all

When you get a value after typing in R type in D and press enter. That will say query failed but if R worked it worked. After that unplug power from controller and start the script again and type R, that'll be the raw value from the circuit so we'll know where the problem lays. Also try unplugging your probe and doing R to see what value you get, should be around 4.1.
The circuit can manage calibration on it's own which I'm discovering can be a problem, I'm just going to remove all the extra features from the circuit as they aren't being used anyway. If it doesn't start working maybe start a new thread about this.
Sorry I can't help with the API.

hello very nice project im new to raspberry pi and i want to start with ph monitoring but i want to add more in the futur what box should i buy and what part for the ph since i already have the raspberry pie zero wH ? ThanksWelcome to the development thread of reef-pi, an open-source, affordable, modular DIY reef-tank controller based on Raspberry Pi.
If you are trying to build a reef-pi controller, please check out the build guides linked below. You can use this thread to seek help and to stay updated with the latest development.
reef-pi provides following functionalities:
A beginner friendly list of reef-pi build guides are available on adafruit.io, if you are planning to build a reef-pi controller start with them.
- Equipment control or automated power strip (including digital timers to switch on/off equipment at periodic intervals)
- LED light control (24 hour cycle), diurnal cycle, fixed dimmig
- Auto Top Off (based on photoelectric water level sensor or float switch)
- Temperature monitoring and control (switch on/off heater & chiller)
- pH monitoring
- Dosing automation
- Macro (feed mode etc)
- And several other features like camera controls (periodic image capture and upload on google drive), telemetry (dashboard and alerting based on sensor values using adafruit.io), mobile friendly UI etc.
Since reef-pi is modular and customizable, the cost of individual builds varies. In our experience reef-pi controller are almost always cheaper than the commercial alternatives and costs anywhere between 100 to 550 USD. An example bill of materials can be found here as amazon list. If you are building a reef-pi controller, I highly encorage you start a build thread and tag it with #reefpi to seek help with your build

- pH monitor
--------------------------- Original thread start ---------------------
Hello friends,
I am starting a master thread for a DIY reef tank controller that is based on all opensource software and hardware. I had started with this project with following goals:
- Build an opensource software and hardware based reeftank controller that anyone can use and hack
- Keep the controller well tested against a set of standard equipment I use, while make it possible for other equipment to be used
- Maintain my own tank build threads and their evolution, backed by this controller.
- Learn electronics and reef keeping along the way (I am biologist by education & software engineer by occupation)
Following are the details of what I have developed & tested till now:
Controller software:
- The main controller software is called reef-pi. It is written in go, its fast and performant. It used embd for hardware communication. It also runs a little web server which provides the UI for the controller. UI is written in React , and can be accessed from anything that has web browser. As of now, the reef-pi supports following things:
- AC 110/220 V socket on/off (uses optocoupled relays underneath). This is used to remotely switch on/off return pump, LED bulb, heater etc.
- 0-20 Volt DC PWM. This is used to control things like dimmable LEDs, DC pumps. I use it to control my Kessil A80, A360. As well as a 5V DC pump (i use it as wave maker in one of my pico with SPS). PWM is done using PCA9685 breakout board from adafruit. This board supports 16 channels. I am using only 5 at max, as of now.
- Analog sensor support using MCP3008 analog to digital converter. This supports 8 channels. i.e. I can use up to 8 sensors/probes. As of now, I have only tested temperature sensor with it.
Other than the following basic hardware/equipment support, the controller software provides following additional features:
- Setting up daily/weekly/monthly scheduled jobs. Like turning on/off certain equipment. I use this feature to run my AC20 HOB filter nightly.
- Setting up dusk-to-dawn like lighting using PWM. The UI gives 12 vertical slider based 0-24 hours (each slider representing 2 hours gaps). I combine two of these two control the kessil LEDs.
- Authentication using Google OAuth. Since the whole controller runs on raspberry pi and provides an web frontend, security of one of my concern. To mitigate this, I have added google authentication support, which when configured will allow only certain users to log in (email specified in the configuration value).
This is the summary of the core controller software and what features it has as of now. I am constantly writing/improving things around it. As of now, I have two reef tank powered by this. I 'll have seperate threads on the individual builds that will include the housing and ancillary hardware in nano-reef.com, as my tank build threads are there, but I'll share all the controller specific common bits here, including UI screen shots, and tank pics
Are you using my pH board? If not that python script won't work. Did you try deleting the pH from pH tab and adding it back? That will clear the calibration data from the database.

Hi - my reef-pi - I cant view the remote screen on my PC.
Everything was working fine then - no remote screen connection.
- I enter the modem and i can see that wifi is connected and I can see the IP address.
- I can use CMD and ping that IP address and my PC sent 4 and received 4
- The reef pi was still controlling a dosing pump connected on my desk and turns it on each day.. was setup for testing.
- Putty/ putty does not work on my PC
- Checked Pi and SHH it is turned on.
I have run sudo systemctl restart reef-pi.service and sudo systemctl status reef-pi.service and the Pi screen says running.
I have the Pi connected to a keyboard, mouse and a screen but I can not view the reef pi on a screen, tried tablet and PC - no connection. Modem says its connected and I can ping the pi.
any ideas?

Hi - yes a few times.
My next option is to reload everything again....but I would prefer not to if you know what I mean.

Do you have ambient temperature reading? Any chance the heater is not able to keep up ? Or you think it’s a software issue ....?@Ranjib I am seeing a strange trend in temp over the last week.. Here is 7 days of temp graph. Mind you the swing is no more than .5 degrees, but I do have it set at .1 hysteresis.
