@day_trippr, I did lot of your suggestions and change the fridge (was a old frigde for a frostfree one) and after some cicles and after running 3 hours, still ok. Tomorrow I told you if still ok. I solder the capacitor directly on lcd, decouple wires, change some positions of ground and 5v...

I am using this schematic.

Sorry, the orange capacitor is 100nF.

About weird characters, look what occurs when fridge turn off. Interesting is that it occurs only when system send to relay an information to turn off the fridge. When I reset the system and brewpi send the first info to turn on the frigde, the lcd still showing properly. Looking for other...

If I change the Arduino relay to SSR could solve it?

@day_trippr, Arent there other simple way to fix my system? Add more capacitor??? I am asking it, because I have 2 system mounted and change it will be a hard work to me and I have no skill so good to do this. Thanks, Fabiano

@time2brew, I am using your suggested schematic , but after some time, weird characters appears on the lcd. Is it happens with you?

@day_trippr, it doent work properly. Starts working good, but after some cicles of start fridge and heater the lcd start showing weird characters. I will post some pictures tomorrow. And I built my own hardware, but like suggested on the first post of this thread.

My problem is related with lcd weird character. Anybody has this problem? What is the solution? I am using the suggested guide on the first post.

On device 2, change function from Beer Temperature to Chamber Temperature and click Apply.

What is the best way to put a plug that can turn lcd off when we do not need see it but keeping RPi and Arduino running? Is there a way? Thks, Fabiano

I am mounting 2 arduinos uno with one raspberry and my doubt is if have a way to turn one arduino off but no unplugging the respective cable. This situation occur when only one fridge is fermenting, and the other one is waiting the next batch. Thks, Fabiano

Anybody uses I2C LCD 20x4 on your build? Could share the step by step?

Anyone knows in what file/module is difined what port is to be used by onewire sensor and how many bites is difined by the onewire? Thks again Fabiano

Onewire DS18B20 is a digital element, so why we use it in a analogic port instead digital port? Is it better? Is it possible without losses? Thks, Fabiano da Mata

I installed Debian on my olf netbook and now I waiting the hardwares I bought. So, lookink into Brewpi, I would like to ask how should (recommended) be the initial parameters for PID algorithm. My system is for a conical fermenter and 45 L of beer. Thanks, Fabiano da Mata

What kind of connector do you use for probe wire? I imagine that is possible put a connector that be able remove the probe wire when you finish you brew day. Thanks, Fabiano

Yooper, thanks for your reply. First of all, when I add grains I stir them on the first moment and no more. After that, only recirculate the water/wort. The dry sense is related like beer done only with beta amilase. See my setup pic attached. Fabiano

On my HERMS, after measure temperature on HEX output and HEX input, I found about 5-6°C. How I control temperature by HEX output and the HEX input (MLT exit) is colder 5-6°C I am not achieved beer full body (all beer done are taste dry). So, I would like to know how and where do you set your...
