Parabeins. Mais agora Vc esta ativando os relay con so 3.3v, nao e confiavel. Melhor 5v no jd-vcc.

Pode funcionar sim. Vc tei 5v power suuply o esta tentando alimentar por o cabo usb? O mais correcto e alimentar a logica con 3.3v y os relay con 5v , remova o jumper: https://howtomechatronics.com/wp-content/uploads/2015/09/Relay-Module-Circuit-Schematics.png?ezimgfmt=ng:webp/ngcb2

Nao, o wemos d1 usa o mesmo esp8266 . Ele e de 3.3v. Nao conecte ninguna entrada a 5v a risco de gerar fumasa ;-) Vc vay cobferir que as saidas proveen 3.3v Si se presisar 5v debe colocar un transistor con 5v no pullup.

Mais tein un regulador de 3.3v na placa. O ESP so traballa con 3.3v. Desliga o relay e coloca o voltimetro no pin do relay no micro, e verifica si ele prende e apaga cuando o micro ordena. Por otro lado coloca 3.3v na entrada do relay e verifica si ele acciona. E so un relay o una placa de relay...

First thing try each one alone in the RPi, throw away the ones not working. Then remember one wire bus do not like star configuration. Is better tho have 3 wires going around and atache the sensor to that line with short wire. Take a look in hear ...

When many devices are in the bus the length of wire also plays. Some times adding or cutting 20cm on a sensor make all work. As per spect sheet the pull down current could be up to 7mA. On 3.3V the limit is 470 ohms. I have many buses with 8 or 10 sensors to the RPi with 820 ohms pull up working...

Caramelized sugar will not ferment, so you need to get the sugar before that.

Are that plugins ported to Cpbi4?

An image is allway better, no pressure back flow will open the ball.

Well there are different things here. I don't know what will you actuate with the UL2003, but they are NPN darlington, so no power supply . Max81365 have hi gain amp, so the main point is to have good filtering. The relays board have separate power for login and for coils, so power the coils...

Yes. And you put a marvel inside to help stir the milk. Bizarra beer makes a waissen with dulce de leche.

Here in Uruguay ther are several beer with “Dulce de Leche” , that I understand is the same as caramel ( the filling of Mars bars”. It goes good in dark sweet beers.

I tested right now and the addons page loads ok.

More than looking to the pcb silkscreen, check the conections with a tester. Pin 1 goes to GND.

Vc vai ter mais respostas si consultare en english. ;-) Ja olho o BrewPiLess, e opensource e tein tudo o que Vc falo. Si tivese muitos tanques CraftbeerPi o Fermentrack son bon.

Yes, you can. But then take a look at CraftBierPi. Do not reinvent the weel

ESP pins can’t drive the relay directly, need aprox 70mA. The board relay breakout has a transistor doing the driver.

If the flow is not even the the flowmeter may lie. Yo can not calibrate for diferen flows.

1.265g - the co2 inside the fermenter. You know the exact weight cos you know the OD.

After some chemistry calculations, for every 40g of alcohol 44g of co2 are produced. Some of it remains in the liquid and in head space. But the co2 that goes out in the bubbles leave the system, the weight goes down.
