No, the pt100 are platinum resistors of 100ohms at 0C. You need an analog amplifier and interface to reed them. The most popular is MAX31865 boards with SPI interface, one module for each sensor.

The mostfet are to drive the 12v motorized valves, it is not clear if yours are 12v dc or 220v ac 1n4001 are just diodes used for protecting the mostfets when switching the valves. You will need 2 mosfet or relay per valve.

For the outputs you may use a relay board as ZapperMike shows in the picture. The pt100 interfaces are SPI, so they need 3 wires plus a CS por each one. The relays could be connected to port expanders. I use i2c LCD interface to drive an 8 relay board. They are cheap and easy to find. They are...

And , if you add zerotier One to the rpi and you phone/tablet you can control from anyware.

Wifi BrewPi do not need Wemos, any ESP-12 will do. Just add the voltage reg and a usb-ttl addapter for programming.

The motor valves say 3 wire control. That may need more than one output from the controller. Normally them have 3 states, closed, open left, open right. Even open both on some valves. Most PID do not have communication link, so you may not hook them to the system.

May be the arduino one wire comunications option can be connected to the Pi.

Nice, did the flat switch provide some histerisys?

Have you considered BrewPiLess?

Ok, finally got brewflasher running :) the pip command lasted overnight to complete. to run : python3 Main.py and have a happy flashing Tnx for the help

Brewflasher README.md Running from python source on Linux Section Will try cli version

it's a way to flash without brewflasher? Try to follow the instruccions for Linux install and stumble to: git clone [email protected]:thorrak/brewflasher.git Cloning into 'brewflasher'...

Eu testaria o hardware com algun exemplo de oled en Arduino. I wiil say to test the HW with some Arduino Oled example.

About using an NTC and ESP32 ADC, one of them don’t work if wifi is active. The lineality problem is compensated if using the internal calibration paramers set in at factory. For that you need to call analogReadMilliVolts(pin) I got a 4 ntc setup for my fermenters and error is ~ 0.1 Centigrade.

It gets harder in Arduino world, where a new version of a lib may change the API and the IDE push you to update.

I love the sweet finish of Windsor. For an easy recip I use : Maris otter 95% Wyermans Special W 5% Mash at 68c Been a mix of crystal malts Special W is a nice help.

Winsor yeast do not eat tri saccharids, so the final OG will depent of the mash temp also.

I try the tourbine type some years ago for a bottle filler and the foam was disastrous. The filler finally use an inox electrode to sense the beer in the bottle neck. But these “in line” arived after that solution and never where tested. The sensor is hall, with infrared you can “see” all 3...

Hi, very nice project. Any one have tried with this kind of flow meters? They have a propeller like inline, so not very convoluted path for the beer.

Any metal fridg will act as a Faraday jail and almost block the wifi signal. There are a cheap trick with a “pasive repeater “. That is 2 antennas conected back to back, one inside and the other ouside the fridge.
