Thanks for the quick reply day-trippr. I am referring to the jumper on the PIR for Repeat Trigger(H) or Single Trigger(L). My PIR does not have the pins for the jumper so I needed to solder across the pads to create the jumper to achieve "L: Single Trigger". I could not get it to work...

I have everything up and running on a Pi 3 running Jessie and the basics work great, but I can't get the PIR to trigger anything using the pir_test.py script. Is there anything different to the motion sensor setup on the Pi 3 vs Pi 2? Running the output of the HC_SR501 to Pin 26 (GPIO 7) and...

I do it for nearly every starter. It works great and I use the same calculator that theKraken posted above. http://brulosophy.com/methods/yeast-harvesting/

Honestly ... the safest method is a switch that will allow to select element 1, element 2, or both off. You will need the backend wiring, contactor, etc, which are easy schematics to find. I would not depend upon the software side to manage this.

Got it. I am not fully up-to-speed on all the details of exactly 'why', but researching it a bit more I am finding the same conclusion regarding RPM management of AC motors. SSR's are not the correct method and even with DC motors there is debate on the 'correct' method, but all agree it is...

Why could I not control an AC pump via a 120VAC SSR?

Any reason why we could not use the PWM function, which one of the pull requests provides, for controlling the speed of our 120V AC pumps (Chugger, March, etc), utilizing an SSR of course?

I need to pickup some of the bare DS18B20 sensors. Like anything else, I doubt they are all created equal. Are there brands/vendors I should stick with or are they all about the same? Here is an example from amazon: DS18B20 ... but I can't tell if these are cr*p or will do just fine.

jsallen - Did you happen to take any pH readings or do you have the means to take a pH of the finished beer? Interested to see if the pH is as low as you say it tastes.

Just for clarity ... when reading the below malt analysis sheet, for example, the Di pH is 6.0, correct? http://www.weyermann.de/pdf_analyses/r077-001360-01.pdf

As others have mentioned you need to setup 'port forwarding' on your home router in order to access your pi from 'outside' your LAN. It sounds like a fancy word, but it is pretty simple. Basically, you only get a single IP address from your internet service provider (ISP), call it your WAN IP...

Perfect ... that worked. Many thanks!

Has anybody else run into browser incompatibility from the iPhone or iPad? I have tried Safari, Chrome, Firefox, Dolphin on the iphone and they all have the intermittent 5 Sec of showing the text in the LCD window (upper left) and then 5 seconds of 'Cannot Receive LCD text from Python Script'...

Thanks for the info on your approach. Makes sense, but I might reach out when I get to that point. I will spend a couple of brews working through the behavior and nuances of a single chamber, but you gave me the insight I was hoping for and a good place to start. Thx

Excellent news on the side project, thanks for sharing the info. I have got a second RPI sitting around that is just waiting for some alpha testing cycles ... Keep us posted and many thanks for your hours of contributions on this topic ; I would have been lost without your wiki. Rob

Thanks to all that contribute ... excellent thread. I was up and running within a day using the info in this thread and primarily the wiki (Thanks FuzzeWuzze). Running 2015-05-05-raspbian-wheezy and just a couple of quick questions as I start to use BrewPi. 1) A read a few bits here and...

Rather than add a new thread, just wanted to get advice on the exact same questions on mash temps for Piwo Grodziske / Grätzer style (27E). Hopeful to find a happy medium approach for mashing. Considering it is 100% Oak Smoked Wheat Malt grain bill, I am considering the following approach to...

Just closing out the thread in the event anyone else runs into the same question/concern. Faucet works great, no issues. I did reduce the line length a bit which opened up the spectrum of flow control a little more. Rob
