Craftbeerpi

[darren996]

Have to do a bit more reading on it myself

There are a lot of developments coming in 2.2.  You can download a beta version of yhi.

Webpage monitoring at the moment ,  it would be cool if there was an app but the webpage is responsive and looks good on all devices.

In 2.2 you will get fermentation dashboard. You can also connect as many temp probes as you like.
You will be able to load beer.xml files for automation

The never rabbit hole!!

thats really cool! I bought 30GBP RPi3 but then I will use it for OpenELEC for TV and order RPi ZERO for craftbeerpi, so probably you just need an OTG adapter (usb micro -> usb) for a wifi adapter and thats it? (and maybe miniHDMI to HDMI for some screen connection).

BTW I have designed some PCBs for CraftBeerPI you might be interested, there are gerber files as well so you can reproduce it. https://github.com/terragady
it should work with RPi0 as well as the pinout is the same.

I would recommend getting an rpi3 if you dont already have a wifi adapter. By the time you get all the extras you are pretty close to rpi3 price.

I had all the extra bits and pieces fot the zero thats why i got it.

Rpi2 and rpi3 can take a touchscreen. You can get them cheap on ebay.

Have a look at this build

What can you do with the pcb?

Well I guess I know how I will rebuild if the ardbir ever fails

[darren996]

Yeah,  thats was my main reason for looking into something else

[terragady]

I have a wifi adapter and it cost like 1,40$ on aliexpress I am not in rush and I have already RPi3 to test te software. Now I am using still ArdBir as well.
I was not thinking to get a touchscreen, instead I would install normal 20x4 LCD with temp reading etc connected to I2C. The rest I can have on my laptop and smartphone.

PCB is for same reason as Ardbir's. You can connect everything straight to arduino as well but this gives you nicer build and protect RPi from burn or autodestruction. It also power the RPi from 12V source which most of us are using for pomp anyway, so no need of extra adapter. You have ready screw in ports for temp sensors and rest stuff.

That's something I am currently working on.  Based on Leaning Man brewery's project building my control unit. Still waiting for few bits and pieces from China and hopefully will have everything together in next week or two.

Will keep an eye on this thread, interested on others feedback. And will let everybody know how I get on.

Have you got a link for the wifi adapter?

I will be running my pi setup headless and monitoring it on my phone so no need for an lcd or screen.

Zero only has 1 micro usb also.

Any body know if you could wire multiple  DS18B20 temperature probes to control mutiple SSRs? Basically want to know could i use two SSR to control both the boil kettle and or mashtun temperature via two of the temperature probes and two 40 AMP SSRs. Wiring one up is described here http://www.leaningman.com/2016/05/automated-brewery/

I am curious to know is it simply a case of wiring multiple instances of the temperature probe in to the same probes on the 3V rail on the Raspberry PI and then how would two SSRs be wired in?

I have most of the bits needed to get this to work already and I foresee I will be shortly be canibalising my existing PID based herms controller in favour of this. Any assistance on this would be appreciated?

Yep you can have as many temp sensors as you like,  thats why i went with the breadboard,  all sensors share the same 3v ground and gpio header, craftbeerpi will see them as seperate.

You can setup multiple ssr and relays.

Looks like multiple SSRS are handled via different gpio outputs one per SSR.

Kind of makes sense as the software allows you specify a gpio.

Now to confirm whether the SSR required are DC or AC? I assume AC. Next thing for me to figure out can I reuse my existing project box to fit another power output. Time to call the brother Might be selling a PID controller & associated temperature probes soon.

Dc 3v trigger,  ac on the high side, i have one connect ed to gpio 17,  you can see it in the pic,  ita a 40a ssr

When I have less beer in me, we can have a chinwag about this Shanna. It shouldn't be too complicated to do what you want. The pi will send out dc to your ssrs. Each unique state will need a different signal and then your laughing
