Have you guys done anything to use and or certify that you use food grade plastic in the enclosure? It sounds like most people on this thread don't seem to care about that, but if you ever want wide distribution you will have to get some sort of certification that the plastic is of food grade quality.
If I upgrade the firmware to 1.5.0, do I need to recalibrate the levels and pressure?
I'm going to build one of these, but I'm not sure that the temp/pressure is worth the $38 that Digikey wants for it.
I understand that the whole thing is a really cool "unnecessary" gimmick, but do you guys really like seeing temp/pressure?
Will it work if I just don't wire it in?
This looks like an awesome project. Where did you find the ZDSticky Epoxy? Currently I can only find 16oz kit on Amazon and it is clear. Was hoping to get larger capacity jugs to build 6 of these.
Quick question @Schauby7, have you experienced any issues with I2C over wires?
My application also requires a single controller for at least 3 different Flite sensors, but considering that I2C was not designed for long distance communication (in my case 5 - 10ft) I've been thinking of using RS232 or RS485 instead.
Thanks for the help and cheers for the project!
That's easy: Your stuff is working too long in between re-builds. Re-arrange and completely gut and replace your fermentation and serving chambers every 3 months and you will no longer have those issues.in the past I've had issues like that when putting permanently powered electronics inside my keezer.
Okay, finally completed the build on my 4'th keg sensor and headless controller. First 2 are in the keezer and working great. Monitoring via the app on my phone is easy and the features for alerts and trends work great. I have a Mango Milkshake IPA in the fermenter for the 3'rd keg set up and a Porter on deck for the 4'th. Thank you again UncleD for this great project. I'm not an electrical engineer or computer programer but i managed to put these together and make them work. I do have a couple questions/suggestions if anyone can help.
1) The flite temp sensor reads about 8F higher than the temp probe strapped about half way down the outside of the keg. Is there a way to enter a temp offset so the sensor could more closely show the temp lower in the keezer?
2) In addition to showing keg volume in either gallons or liters it would be nice if there was an option to show volume in pints. I know the math from gallons to pints is easy, but after 3 or 4 homebrews, well you know
Thanks again for the great project!!
Sounds good! I'll keep an eye on all of this for my keezer-in-progress.I will definitely look to add a user-configurable offset for temperature in the next update, I didn't realize that there was such a significant discrepancy in temperature between the bottom and top of keg. Great feedback guys, thank you!
@fuzzybee I have not reached out to the RPints team. However the Flite controller has an API that can be leveraged by an IoT device like an RPi to get current information from the controller. Here's some more info:
Also @Thorrak may be working on something along those lines
I've just kind of scanned the thread, but I didn't see anything about integration with RaspberryPints. Is there interest in this?
If you're using Flite with Taplist.io and run in to any problems or ideas, just let me know. I worked with @UncleD a while back to make sure it integrated well, and I certainly want to keep it that way. (I haven't seen a lot of usage yet, but I don't know how complete flite's world takeover is.. yet!)
Getting ready to update the firmware on my headless controllers to the new 1.6.0 release. From posts regarding previous firmware updates, it sounds like my existing calibration points won't be deleted during the update. Just want to verify before proceeding
