Having trouble setting up Fermentrack with Raspberry Pi and Uno R3

[MikeFromNL]

This is my first project working with the Raspberry Pi and Arduino. I began by buying the parts necesscary to build a DIY Brew Pi based on the instructions at http://diybrewpi.wikia.com/wiki/DIYBrewPi_Wikia. I was having trouble installing the software using the instructions here because I couldn't install recommended version of Raspbain and using Raspbian Stretch didn't seem to work because it was lacking PHP5. The comments section of the wiki had a solution to the PHP5 issue but that didn't seem to work in my case.

Then I found Fermentrack which installed smoothly on the Pi and seemed to flash the Uno. I have tried to configure the temperature probes in the Dashboard for the Uno but it doesn't seem to recognize the sensors or give a temperature reading. My wiring is still configured as describe in the wiki (https://imgur.com/a/Nval6).

My stc1000 quit working a few months ago and I have been trying to get this to work since then. I am reaching a point where I am considering giving up and buying the Inkbird 308. If anyone has any information to help me get the sensors working and salvage this project it would be greatly appreciated.

Can you take a picture/describe how the sensors are hooked up to the Uno (including wire colors/which pins on the Uno each color is hooked into)?

 

[MikeFromNL]

I set it up the same as in this picture except my sensors came with red black and yellow instead of red black and white. I kept the red and black the same as in the picture and put my yellow wires where the white ones are.

When choosing which sensor monitors the beer and chamber it doesn't seem to save the changes I make and a message is returned stating that the the sensor needs to be configured but I don't see an option to do so. Also, the Uno is a clone if that makes a difference.

When you were flashing, do you recall which firmware you selected? There's two options - the first one ("RevA") has a different wiring configuration than that image.

Try reflashing with the second one ("RevC").

 

[Thorrak]

There is one other option as well. BrewPi doesn’t support DS18B20 sensors that are in “parasitic” mode. Unfortunately, even if the listing specified otherwise, sometimes sellers have been known to sell parasitic sensors.

I have a firmware that tests for this for the ESP8266, but not one for Arduino UNOs, unfortunately. If reflagging with the RevC firmware doesn’t fix your issue, you might be able to find a firmware you can flash to test if your sensors are in parasitic mode online somewhere. If you can’t, post back here and I’ll see if I can whip one up for you.

There is an Arduino sketch that was written and posted over on the Cheap BrewPi thread. This is what I used to test them.

Parasite Mode Test

You'll have to wire up the sensor to the Arduino as described, then flash the sketch to the Arduino using the Arduino IDE.

I will get this firmware added to Fermentrack tomorrow. Very useful.

I will have to look at this when I get time. It’s identical to my problem. Hopefully revision c works.

Did Revc work for anyone

It should work with everyone.

If your Arduino works with BrewPi, it will work with Fermentrack.
