Yes okay. Thanks for that. This looks like exactly what I need to use.
Can someone lend a hand in what code I need to execute here?
The section that says has me confused and feeling like I would definitely mess this up:
“ NOTE: It is recommended you create the tilt folder before launching the Tilt service for the first time. Failure to do so will result in the docker service creating the folder as root. If this happens, use chown to change the user and group ownership of the tilt folder to match the rest of the BrewBlox directory.”
So, because I have already launched the Tilt service how do I creat the ‘tilt’ directory and change the user and group ownership. From there I should be able to handle the calibration file.
If I eventually find some time, I’ll update the service to make use of some new features in brewblox so calibration can be edited through the web interface. But that will probably be some time off yet.
This is likely because you haven’t got enough calibration points. As the docs say, I recommend having at least 6 calibration points evenly distributed across the range you expect to use your tilt. e.g. callibration points at 1.000, 1.010, 1.020, 1.030, 1.040, 1.050 if you expect to brew with OGs up to ~1.050. The calibration code fits a curve rather than a line. If you don’t have enough points across a big enough range, that curve might end up being completely wrong.
Whoops sorry what I said above is not true. Honestly the tilt is going up and down quite a bit and that is throwing me off somewhat.
It is calibrating in the wrong direction tho. The calibrated value should be higher not lower. Just did another manual check and this what tilt app shows
Ok added a few calibration points then ran brewblox-ctl restart and brewblox-ctl- up but no UI is completely non responsive.
Here is the error log from the UI
Ok. I think that I have fixed the datastore issue. Basically, just need to wait a long time after running the restart script.
However, can you help me troubleshoot why my TILT hydrometer is not being picked up. The bluetooth dongle is right next to fermentor which is stainless. I have a usb bluetooth dongle attached to a USB extension cord running outside the freezer and into the rPi. I can get the signal from my phone. And at least for a few days this set up worked fine.
It wasn’t until I tried to run the calibration settings the 2nd time that I lost the connection.
There’s no support in the code for multiple bluetooth receivers at the moment. The code is likely just connecting to the built in bluetooth receiver on the raspberry pi and not the dongle.
Ah. No it doesn’t. But the interface to your dongle likely won’t have the right name. But using a raspberry pi 2 will probably explain why you were having issues with it taking ages for the data store to come up.
