First: many thanks for bettering brewpi with this cheap hardware, I had the idea some months ago but neither got time nor skill to carry it through.On topic: the buzzer is pretty useless imho as it in the original inplemented function was used to buzz at startup only...The rotary encoder is...

I ran my setup (i2c, rotary encoder, sainsmart relays, 230v, lrd dimmer) for at least two weeks without fridge or heater connected and there was no scrambling. When I plugged in the fridge and the heater, scramling occured, and I have seen the scrambling kick in when cooling was activated...

Grand that you have got it working! The intermittent "cannot read from lcd.." can be fixed by changing the KeepAliveTimeout 5 to KeepAliveTimeout 99 in apache.conf and then restart the raspberry pi. Regards /A

I struggled a while as well and did the ame thing: swapped the data lines etc. But if you tested with an example sketch and it displays readable text on the LCD that should not be it, one possible thing could be the adress of the I2C module, the adress of that should be 0x27 I believe, and some...

Well, the electromagnetic interference that may garble the LCD is caused by that the relays are not synced to the frequency used(120V/60Hz for you US guys) so when the circuit is altered it may cause a lot of induction. Scrambling may be even worse with 230/50Hz (used here across the Atlantic)...

The snippet of code should be inserted into brewpi.cpp and the main loop that run the avr (line 100 of the legacy branch). For that you need atmel studio 6.2 setup (and turn on line numbering somewhere as thats not on by default) Do note that the attached hex file link is for a modded arduino...

Hi, I have a working setup with an I2C backpack to a 20x4 LCD with a rotary encoder and automatic reset every 2 minutes (and Bluetooth, thanks day_trippr!). Link for download : http://s000.tinyupload.com/index.php?file_id=15700787823698715094 , it is for an Arduino UNO, I2C backpack with adress...

So you are going for a multi chamber setup? Thats advanced. The path for www files need only be changed to ../html for Jessie but if you use older raspbian it should not be changed. Also make sure you download the legacy branch from git with the -legacy switch both for the script files and the...

Glad I jumped on the bandwagon and got me one.:) I thought the SD card corruption was a long gone bug by now though? Ive never had that occur and have not been kind to my Pi1 nor the new. /A

The knock off arduinos publish themselves as /dev/USB0 (more on that below) and that port need be in /home/brewpi/settings/config.cfg as: port = /dev/USB0 to suit your arduino version. Use nano to edit the file using: sudo nano /home/brewpi/settings/config.cfg I initially tried to download...

I believe the reason is a bug in the way that the browser expect data and while I have not corrected it it can be supressed by changing a timeout value in the python script from 5 to 60. After that Safari, MS Edge work as fine as Crome at least for me. -Ill see if I can digout exactly where...

In accordance with the laws of thermodynamic, the coldest surface will be the one with condensation, and that will be the cooling element, so in fact a single un-insulated glass door will work, but the fridge will be less effective /A

Some notes for potential diy:ers: Wall of text follows... I struggled a bit following day_trippers excellent writeup on how to setup a bluetooth link, but it boills down to the "latest and greatest" illness of using raspberry pi3 as that had built in bluetooth as well as wifi. - I needed...

Thanks, got it and its working! pic from my cluttered desktop:

Tnx for this and saving me frustration later on.. I though I was home free when I could get a HEX file for brewpi working on the Uno with the now familiar text, but I found herrfrost:s implementation of software I2C on github since onewire pinout was hardcoded in several places and it will need...

Just a thumbs up on finding a hex file for the arduino (and a new python.py file that is needed) . Was right under my nose in this thread: https://www.homebrewtalk.com/showthread.php?t=510036&page=31 Note that the lcd need a4 and a5 on the arduino so some rerouting is needed. Now I just...

First: A big thanks for all the hard work here to support brewpi, I was starting off by reading first post and hit a few hurdles, but particulary the wiki set me off right. Newer debian (jessie) works (and I have a dual chamber set up) but all web pages and references should go to /var/www/html...
