It's easy if only one or two types of bottles is used. Timer, if flow rate is fixed. weight. volume. distance sensor. detecting beer level by resistance. I am building a filling assistant which measured by weight currently: used in two batches. Still a lot to be done, but satisfying so far.

The missing code is added. D8, aka GPIO15, must be HIGH to enable normal boot up. If you pull it to low, EPS8266 won't boot normally. Most ESP8266 solutions, like EPS12 or EPS01, connect D8 to Vcc via a resistor. You can find the schematics on GitHub or Espressif's website. The code will run...

I used keg, and I bottle again. I've tried beer gun, counter pressure filler, and pegasus bottle filler. I got mixed result. Well, we don't need to diss kegging here. Let's focus on bottling. There is another thread about headspace...

If you are living in a warm and humid area, condensation and isolation would be problems for glycol. That is the only condition when fridge might be better than glycol chiller. Condensation "releases" heat and encourages mold growing in warm temperature. Keeping temperature using glycol chiller...

I implemented pressure control in BrewPiLess. However, my hardware building skill sucks and I haven't run it in real life. Some people do report working, though.

I forget where I read it, but here is my google result: https://ba0sh1.com/2016/08/03/is-esp8266-io-really-5v-tolerant/

I seldom visited this forum since the mobile version died. Sorry if i missed some of your questions. Some updated regarding BPL project. 1. Spunding control "seems" to work. Yet, I haven't built the hardware myself. 2. TILT with ESP32 seems to work. I don't have a TILT to verify, yet. 3...

Glycol chilling is a secret function I've used for myself. To use it, you need to assign a PIN, or actuator, to "PTC Cooler", which will used to control the relay for the glycol cooling. Then, you will find the glycol setting on "Control" page. Room sensor is used for glycol temperature. To...

ESP8266 is said to be 5V tolerant. I've connected my LCD to 5V power and direct to I2C pins for years, since the beginning of this project. It has been working fine so far. I might be lucky, but you might be as lucky as me.

According to the code, when the door is opened, detected by the pin, the light, if assigned, will be turned on and an event will be logged. The log event is ignored by BPL, though. I just don't care about the door.

There is a button, titled as "System Config", at top-right corner of the page. You should consult your Router provider for DMZ related settings. BPL has nothing to do with those DMZ settings.

Sorry for late reply, your question is too trivial or too difficult to answer. The settings in in "System" or "Config" page. I don't know why you can't find it. The default settings in **code** is in file config.h. BPL is open sourced, and you can change as you want.

No. If the gravity data is calculated by iSpindel, no way you can change it. ... Therefore, BPL can calculate the iSpindel and even derive the formula based on the data input.

It might be an issue of settings. After v3.0, all settings are merged into one file for optimization. When you upgraded from v2.x to v3.0+, all settings were gone. Just go through all settings again.

One BrewPiLess can't control TWO fermenters. None of the BrewPi 0.2.x variants can.

The PID algorithm comes from original BrewPi 0.2.x. You might google for more information. I don’t know much about PID. I would suggest to change other parameters, like heatTargetHigh and coolTargetLow.

You can use D5, D7, and D8. Use D8 for heating, I would suggest. Or, you can try ESP32. It has more PINs available.

iSpindel works really well for me. I can see the drop of gravity usually before 12 hours after pitch, when usually no bubble shows at that time. The slow down of gravity change speed is so obvious that it can be recognized in around 4 hours.

kind of mysterious to me, bu the change of underlying WiFi implementation maybe has caused some issues, which I have not solved all of them. The last one is losing WiFi network after a week or so. I just push an update which will store WiFi credentials. (I relied on the underlying WiFi...
