Wow!! Nice to see this project still going strong...
I'm finally getting back to brewing after a year hiatus... will have to clean up and finish the work I was doing on my rpints with the rfid reader...
The new raspberry pi zero is out and it's $5. It has a spot for the gipo header but it isn't attached (you have to add it) it also does not have the on board nic, but you can add a nic as well via usb.
Double check the connections on the meters and the tubing. Any little bit of gap or air can affect them. Also psi around 8 seems to be ideal.
It's a lot of trial and error.
Doesn't chrome on android recognize the meta refresh call?
You can add a meta refresh call to the main index.php page to refresh the page every 5 minutes (or 1 minute if you want)
In the pours.php script comment out the part that calls for the refresh of the screen.
I think the error you're seeing is related to the fact that it's trying to refresh window 1 but you do not have a monitor with a browser open connected to it.
The auto refresh on a pour only works if you...
No. There's math involved in the python script that reads the info from the flow meter.
I don't know where it is from memory, I'll check the code when the sun is up and let you know.
It does not currently send a "Kicked Keg" message. It will however, keep pouring if you have more than 5gal in the keg.
The reason was that there wasn't a reliable way to determine if a keg actually kicked using the flowmeter. (I was getting faster readings from the meters depending on the...
I'm going to go out on a limb and say, no. The flowmeters will not currently work with this setup on a tablet (unless the tablet is connected to an arduino via USB connection.
The issue comes in that the code is running on the rPi to constantly watch for input on the serial connection from the...
