    Did you read my post? Sigh

    HOWTO - Make a BrewPi Fermentation Controller For Cheap

    If if gets hot, you connected it wrong. Your Arduino turns off because the sensor draws too much current. Next time, only connect data and GND. If you confirm that those are correct with a test sketch, then connect 5V. You can throw away this sensor.

    HOWTO - Make a BrewPi Fermentation Controller For Cheap

    With 5V disconnected, DS18B20 sensors can be powered through the 4k7 resistor via the DATA line. You can find an address for them. We detect whether they are parasitically powered and do not show parasitically powered devices in the device list, because 5V should be connected for reliable...

    HOWTO - Make a BrewPi Fermentation Controller For Cheap

    If 5V to the sensors is not connected, a sketch can still find them. BrewPi ignores parasitically powered sensors, because they cannot read a temperature reliably the way BrewPi configures them.

    Thanks for confirming. I have already merged the dev branch into legacy, so you can use the legacy branch again.

    HOWTO - Make a BrewPi Fermentation Controller For Cheap

    Has no-one tried the legacy_dev branch yet? It will make flashing from the web interface and even from the install script work again. But I need verification that there a no other bugs before merging it into legacy.

    HOWTO - Make a BrewPi Fermentation Controller For Cheap

    Hi Guys, BrewPi founder here. I have just updated the legacy branch of the script with everything that is backwards compatible and pushed this to the legacy_dev branch. (legacy branch unchanged for now). I have tested with a Leonardo and I can program it from the web interface, and even...

    What makes you think this is the case? Is there a way to confirm or reproduce the behavior?

    Disable the wifi checker by editing /etc/cron.d/brewpi change: entries="brewpi wifichecker" to: entries="brewpi ~wifichecker" Then run updateCron.sh [Errno 13] could not oopen port /dev/ttyACM0: [Errno 13] Permission denied: '/dev/ttyACMO' That last digit is a letter, not a...

    Wbarber, if he cannot acces the serial port, resetting thr EEPROM on the arduino wont do anything. It is not the magic fix for all problems and the command won't even work. Make sure the brewpi user is added to the dialout group. Otherwise it wont have access to serial ports. If you see acm0...

    HOWTO - Make a BrewPi Fermentation Controller For Cheap

    Sigh, that's what the legacy branch is for. It has all the things that are backwards compatible with Arduino, including the new pyserial. If you just update to pyserial 3.0,the new default, it should work just fine. I keep the legacy branch up to date with things that are not Photon specific...

    That is not the latest version of the code. I refactored the code afterwards. Make sure you are running the latest version. Run this and show the output: python /home/brewpi/autoSerial.py

    HOWTO - Make a BrewPi Fermentation Controller For Cheap

    PySerial was updated 2 days ago to 3.0. This broke some things in the BrewPi code, which I have now fixed. I have updated the legacy branch with most of the backwards compatible changes. this includes: - Receiving serial data continuously in a background thread. This increases...

    If the lcd scrambles when powering on the heater or cooler, use SSRs instead of mechanical relays

    Klucky_13, the 0.4.0 is for the BrewPi Spark only. If you are running on Arduino, run the update script with --ask and choose the legacy branch on both the script and the web interface. The full command should be: sudo ~/brewpi-tools/updater.py --ask If the devices are not storing, you...

    HOWTO - Make a BrewPi Fermentation Controller For Cheap

    Hi Guys, A reason for creating the legacy branch in the main repo, is that I can merge commits that will also work on the Arduino into the legacy branch. For example, a button to reset the EEPROM could be handy. I just have not had the time yet to go through the commits to see which ones...
