OK, I was hoping that was it but still not working. I put a meter on it during the pour. Before the pour I have 4.98V. Start the pour and it’s bouncing all over the place. Below 2, an occasional over 4, and everything in between. I’m guessing that’s the issue but what is causing it is the...

Good thought. I’m not using a pull-up resistor. I do recall the voltage bouncing around 2-3 V. I’ll try that and report back. Thanks!

Hard to say for sure. The water is a hand pump pressurized container. I’ve got my keg of beer with about 10 psig counter pressure. West coast IPA. I’ll try to fill a keg with water with same physical configuration to rule out those setup differences.

Exactly. I have a dummy test beer set up on the tap. If I take my beer line cleaner container full of water and run it through the line with flow meter, it registers the “pour” just fine. I then hook up a keg with beer to the same line/settings and do not change anything other than tapping a keg...

Thanks for the feedback. I’ve been using them for years as well on the original r-pints as well. I know my setup physically works and have had foam at times too and it has works. I recently decided to move to RandR+ version and haven’t been able to get it to work on beer. It does work on water...

Not really. I get a little foam in the beginning but was pouring without foam for 2-3 seconds before shutting off.

Thanks so much! I've run the update and here is the output of the log after running beer through the tap. pi@rpints:~ $ tail -f /var/log/rpints.log 2020-07-11 13:05:13 RPINTS: Not Configured to run Fan 2020-07-11 13:05:14 RPINTS: waiting for Arduino to come alive 2020-07-11 13:05:16 RPINTS...

I’m running the RandR+ version. I’ve looked at the log and when running water I see the pours recognized just fine. When I put the beer on and pour through tap, nothing registers on the log file. I put a meter on both pins when beer is running and I can see the voltage change as beer is running...

I’m at my wits end. I can get my Swiss flow meters to register pours with water, but as soon as I put a keg of beer on, it doesn’t recognize anything. I have two taps with meters and same thing occurs on both. Works fine running water through, once keg with beer is on, doesn’t recognize pours...

I am about to do the same. I don't think there is any reason not to. Biggest concern for me would be wild yeast contamination, but the risk is low since it would be difficult for the wild yeast to "overtake" the brewing yeast. I would wait until after primary fermentation which is normal dry...

The mash is a natural buffer, so I would check the pH in the mash itself. If you are 5.2 to 5.6 I would say you are OK. If you end up higher than that, then I would adjust the water pH when you brew with citric or phosphoric acid (food grade). As far as efficiencies go, you are pretty low...

Well the pressure has to come from somewhere. Either the beer or the CO2 cylinder. If the FG is stable then it has to be coming from the gas. And as fast as it is rising, it sounds like you have a faulty regulator.

You may have under aerated it. If you do repitch, I would aerate it again to be safe.

What was your final gravity? Are you sure it was completely fermented out? Sounds like you may still be producing CO2 and building pressure or it could be a problem with your gas system regulator.
