First of all, I am not happy about the head space left when the wand is removed. I try to leave about 1/3" or less space. Seoncd, not very often but it happened a few times to me that some debris was stuck at the spring. The wand would then start to drip. Last, it is like jetting out initially...

I've used clamp and it's very difficult to control flow rate by using a clamp. I would suggest BierMuncher's bottle filler. I created a bottle assistant which controls the flow of beer into the bottle on a digital scale. An Arduino is used to read weight from the scale and control the flow by...

I paid $3 for 100g while 500g is $7. Just bottled a (small) batch of Marzen, dosed by my auto doser. 50%Brix sugar solution is on the left while AA solution is on the right. If AA is mandatory thereafter, I will just mix AA in the sugar solution. I made AA solution with 1.5g AA in 50g water...

The PID V2 library is included: https://github.com/vitotai/BrewManiacEsp8266/tree/master/lib/Arduino-PID-Library-master I just found the updated library and haven't tried it. I bet it should work fine. http://brettbeauregard.com/blog/2017/06/introducing-proportional-on-measurement/

I found that the source I had locally is different from that on Github, which was patched by @lekrom. It takes a while for me to find out what's wrong because of the very misleading compile error messages. You might try the latest source that I just push. (Only sources are updated.) BTW, I...

I guess it's something related to framework/library messing up. Try compiling this example and see what happen https://github.com/espressif/arduino-esp32/tree/master/libraries/Wire/examples/WireScan

The source files in your log seem to be different from mine. Which version do you use? The first error complains about TwoWire() in BrewLogger.h, which is used for data logging only. I don't see why there is implicit creationf of TwoWire object.

I bottle directly from the fermenter and add sugar solution direct to bottle to lessen introduce of oxygen. Using a syringe is PITA, so I built an auto dosing machine that can dose programmed amount of liquid, which is usually sugar solution. Dissolving AA in the sugar solution is a simple...

Running on ESP32, BrewPiLess, my project, supports Tilt. Although, BPL, derived from BrewPi, is designed to be a fermentation temperature controller, I've added as much as possible features, including humidity, pressure, and gravity monitoring. (Maybe it's too much in my opinion.) The latest...

Those might be some of the problems. However, I believe that the radio does interference ADC according my googling, like Fluctuating ADC with stabilized source · Issue #2070 · esp8266/Arduino

I was planning to control pressure by venting, and I don't think it's feasible solution by turning off the radio.

Is your pressure reading stable? I've tried ADC of ESP8266 for pressure reading in my BrewPiLess project. It's very unstable. I checked the document of ESP8266, which states that ADC is used only for WiFi module and will be affected by WiFi operation. I have to use an additional ADC module...

No experience with OYL021. Just brewed a HEFE with WY3068, bottle conditioned for only one week and put all in fridge. Tasted a little sour for the first 2~3 weeks. The sourness disappeared, or almost disappeared after that. YMMV.

I build an automatic sugar dropper to dose precise sugar solution into bottles. Priming sugar calculation is built-in. Input temperature of beer, desired carbonation level, BRIX of sugar solution, and bottle volume, and it will dose precise dosage of sugar solution into the bottle. It's precise...

https://github.com/vitotai/BrewPiLess/blob/master/doc/OtherURL.md The LCD refreshing code has been there since the beginning. However, it didn't work because of a typo. It's fixed in 4.2pre, which is currently under test. https://github.com/vitotai/BrewPiLess/tree/4.2pre

Both could be possible. WiFi operation drains more power and might crash the system when power supply is not enough. Try formatting the filesystem if you can. It might help on software's issue.

Are you using SSRs or an Relay Module with usually blue or black blocks? Usually, you should set "Inverted" for Relay modules, and "non inverted" for SSR. Try connect direct from 3V3 and the GND to the input of the SSR or relay module, and see if it "clicks". Measure the voltage of the output...

NO one mention something like this yet. Really? https://www.amazon.com/Magnetic-Bottle-Opener-HQY-Version/dp/B013P9WN6G

The fan is controlled by the "core", original BrewPi Arduino code, and it will be turned on if and only if heating or cooling is active. It's nice that you have all the source code, and so you can do whatever you like.

I fill bottles from fermenter directly because using a bottling bucket introduce chances of contamination and oxygen. I add sugar solution directly into bottles by an automatic sugar dropper: I used filler like what @Beermeister32 does to fill as full as possible to have as little headspace as...
