The Lab is looking for gross data for the titrations. As pH increase to 11, there is an equilibrium equation change for carbonate side. So, what you expect happen with alcalinity (reduce less then for bicarbonete reduced, because some bicarbonete redution could be associeted by shift of...

@ajdelange, pH goes to about 11 and I am using only one column (anionic). I will try take the results before and after titrations.

Bicarbonate was measured by Standards Method (SMEWW - 2320 B ).

I did a test of the water that present 2.1 mg/L of chloride and 226.9 mg/L of bicarbonate. I passed this water in a ion exchange resin column (basic strong anionic) for bicarbonate removal. The bicabonate content reduced to 126.5 mg/L, but the chloride content rose to 48.0 mg/L. This type of...

TH, EZ water spreadsheet help us to calculate how many salts we should add to adjust our water. So, some salts have H2O on their formation (hydrates). My doubt is: should I adjust the salt mass to considere this hidratation? I suspect that mass is to pure component (CaSO4, MgSO4, CaCl2....)...

Make sense my doubt? Or epsom, gympsum, CaCl2 labeled on spreadsheats already considere hydrate (water)?

People, EZ water and Bru'n Water spreadsheet help us to calculate how many salts we should add to adjust our water. So, some salts have H2O on their formation. My doubt is: should I adjust the salt mass to considere that water? Because I suspect that mass is to pure component (CaSO4, MgSO4...

I used startup launch. And I dont believe Brewpi uses this gpio, because it doesnt use GPIO. Brewpi use Arduino to control. RPi is used only as webserver and setpoint loader. I will do a clean installation. So, look at the picture attached. Thanks, Fabiano

I tried other GPIOs, with no sucess. I run as Pi user. I will take picture when I come back home. I used a Debian instalation where I was using Brewpi. Do you agree I have to reformat my microSD again and start a new instalation? Thanks, Fabiano

I have no sucess to put my SSR to be turned on by RPi. I am using GPIO 24 (GPIO24) and when I try put PID to heat HLT, the algoritm tell me that is heating, but SSR doesnt switch on. May I ue some overlay for GPIO24? Thanks for any help, Fabiano da Mata

I have two brewpi. One I can access from any device. The other I can access only from smartphones. Why? This one, I cant change data logging time sampling. Why?

Who implemented brewtroller on arduino mega, could you share your code? Thks Fabiano

People, anyone has a wiring diagram to connect LCD (I2C) on arduino mega? My setup is a e-herms, with 2 heater element (HLT and kettle). I recirculate wort with a chugger pump. So, I will construct my own Brewtroller on an Arduino Mega. What is the correct version to this board: BrewTroller or...

My RPi is not accepting network cable. When I plug network cable the RPi is not recognizing it. I put the same cable on the other Brewpi and works well. So, I imagine the my RPi maybe burnd the network socket. How can I test to check it? Or can be other problem and is there a solution?

I'll try. My fermenters are 100 km from me

@2kegger, when possible, let me know what parameter is it (are them).

@thekraken, I have 2 Brewpi and both of them when set to control beer temperature (Beer Profile) to 18,0°C the lowest beer temperature achieved is 18,4°C, and looking to settings I could not find what change to do to fix it.

Nobody?

My both Brewpi are set to Beer Profile 18,0°C, but the lowest temperature are in 18,4°C. Why?

Anybody uses a Raspberry watchdog? I am looking for this on web.
