How are you fermenting?

I'd like to run the walk-in, and well as a few heat wraps/belts inside the walk-in. Otherwise, I will have to run separate Ranco units inside.

the heat wraps are easy, 10A relay with standard wall outlets. What kind of chiller is on the walk-in?

I've already got the walk-in wired with an independent 15A circuit with outlets. The compressor is 1.5 HP, dual internal fans, all 240V.

Rainy day so I figured I'd wire up the BrewPi (I have nicer probes on order).

The pre-built BrewPi itself is trivial, you could be up and running in no time. The Raspberry Pi build isn't difficult, but it helps (a little) to be familiar with UNIX, especially for the multi-device setup. Ancient, I could build the environment and multi-Pi setup and send you an image of the memory stick. Or build one for you and send it to you.

Finally catching up on a few things...adding Raspberry Pints.

Now I just need to find some cheap flow meters.

Oh man I am getting pissed off. I am about $500 into the BrewPi and two sparks, but the lack of functional documentation sucks. I have one pre-programmed Spark, but I saved money by buying the board kit. I have 4 temp sensors and the SRMs to drive power circuits... but nowhere it says to connect the Sparks (Spark + BrewPi module) to the the master BrewPi build. Finally just connected via USB - and the pre-programmed devices shows up, but the unprogrammed doesn't. Now I wonder if it even has the Noobs build.

Too late to do much about it, but Jeez. So much for the premium...

Sorry, I can't help, I built all mine from scratch. I don't know the process with the premade stuff.

On this latest one, I have the pre-built Spark (v2 with Photon) and it came pre-programmed. It boots into test mode, then you can connect it to the Pi and connect via web interface (which it sounds like is working). I don't know what I did to get it to connect to the Pi, but I plugged it in to the pi and on the maintenance panel clicked on Program (don't select a BIN file) so the console window at the bottom would refresh. I might have had a permission error as I configured the Pi to support two multiple Spark's. Eventually something popped up that showed me it was connecting. But it seemed to take a while to connect. But then I was able to go to the Device list and refresh/program the probes.

Do you need to flash the unprogrammed Spark with firmware?

I did also experience that Elco needs to re-write the pre-built version documentation. It's actually more obvious how to build one from bare parts from Fry's then to buy the pre-built one. Had I not built one of these from scratch before, it would not be one-page obvious what to do.

Yeah - it looks like there is a slight mismatch between the documentation and the last builds - several of the python scripts are missing on the Raspberry Host BrewPi build. Also - I am attaching two BrewPi Sparks and it just doesn't like that. I was hoping that once these are wirelessly connected, I can home the Host inside the house somewhere and add some other functions. There is nothing about these Sparks streaming their data over WIFI as recognizable devices... but will keep banging away.

I was able to update the Spark Arduino on the second device - so that is at least working, and the sensors are functioning fine.

Ok. I got one device configured and running in test mode. I just cannot figure out how to connect 2 Sparks at once, or connect to them remotely over wifi. Back into the documentation.
