Actually mine is also crazy out of line as well, once this beer finishes I will have another attempt at calibration. Probably late nov I think.
I started with adding 15gr of lead at the bottom to get it to float at approximate 45 degrees in pure water. Then I put the device on a horizontal surface, connected the device and went to Maintenance and Calibrate. It took some minutes and then the device rebooted. Now I calibrated it with sugar and water and it ended up quite good. Still I’ve a error about 1 Plato in pure water so I plan to make a better calibration during next brew.
Thanks for the responses. For me, It wasnt clear from the docs whether to do the “lie it flat” calibration before or after the “various sugary solution” calibration. So I have two data sets, that i put into the spreadsheet calculator. 1 set at about 78-79 degrees of tilt and another set (after “lie it flat” calibration) at about 83-84 derees of tilt.
I have NO additional lead weight.
The attached image is the formula i’ve put into ubidots derived formula field, but the ispindel out tilt degree readings that result in Plato numbers of around -3 for when the ispindel is floating in pure water, so not correct!
I have not got my calculator out yet to check the maths, but will do so soon. Any thoughts on what might be going wrong
appreciated.
And here is the spreadsheet for the data set that is currently being used for the Plato calculations. (Ignore the Plato Formel is lower left - some macro issue)
Intersting data set, looks like the lead weight gives a better line/slope and less deviation. I’ll order some fishing weights!! Thanks for that.
I’ll have to find where I read the recommendation, but I believe it is recommended to add weight to get a tilt of 15° - 25° in plain water.
Edit: I found the reference to the degrees of tilt on the Hobbybrouwen.nl page. Part #3
@gromitdj All good now, added a weight to the bottom of the sled, and removed the “^” from the derived formula. Now the readings make more sense. Thanks!
Anyone playing along at home with my fork I did some clean up and have now made
docker pull charliwest/brewpi-ubuntu
&
docker pull charliwest/brewpi-raspbian
Untested with a real world test but runs ok for me.
Still have issues with the coloured lines of the graphs I havent managed to work out
Has anyone integrated the BrewPi legacy version with the ISpindel. I am particulary interested in using the ISpindel as the beer thermometer
Greetings,
FYI I am working on a different approach, because iSpindel is already able to publish its metrics into a time series database (InfluxDB), I have added the support of this database to BrewPi (the legacy version).
This way metrics from both equipments can be displayed using monitoring tool like Grafana.
This stack (BrewPi + InfluxDB + Grafana) named BrewMon can be deployed using docker-compose in a Raspberry Pi.
I am just brewing my first beer with it.

Hi Ben,
We’re actually using influx for all our data logging in our new BrewBlox stack.
We’re using our own graphing and dashboard implementation because Grafana isn’t very good at integrating into another UI.
We did make it easy to integrate new hardware by providing a message bus that you can just push your data onto and our influx service will do the rest.
Perhaps it would be easier to integrate with our new stack than rolling your own. It’s also a microservices architecture and uses docker-compose to start all services.
You could of course still use Grafana next to the main UI with our stack, but I think it is nicer to have your charts next to your other widgets in one customizable UI.
I saw in your PR that you are running the old Arduino version of BrewPi, which we stopped supporting. We didn’t put any effort into supporting Arduino in the new stack, because how the new firmware works and communicates is completely different.
Cheers,
Elco

HI Elco,
Thanks for your reply,
I was unaware of the BrewBlox stack, it looks very promising
I will give it a try and see how I can contribute
Best regards

I’ll add you on our Developer slack.
Hi there,
Does anyone know why I get the following error:
Error response from daemon: pull access denied for charliwest/brewpi-ispindel, repository does not exist or may require 'docker login‘
I have the latest brewpi Spark, all up to date.
G’day Charliwest,
No unfortunately, not.
I have the ispindel outputting to a graph on ubidots, displaying temp and tilt. I can access this on the internet.
I tried to setup the brewpi so that I could access it on the internet (using a VPN) but couldn’t get it to work after many hours of trying.
So there’s no real advantage for me to incorporate ispindel to brewpi until (if ever) I can work out how to connect to brewpi via the Internet. I have ubidots as a bookmark, so it displays instantly anyway.
I only use the ispindel to check the relative SG (I did not calibrate it) to check if fermentation has kicked off, and when it flattens out, finished. I use a refractometer as it’s fairly quick and easy to use. The temperature indications on the ispindel are very good too. The only issue that I’ve had with the ispindel is the USB charger connector snapping off, so I now charge the battery directly with a lipo battery charger that I use to charge my drones (I just soldered a connector onto it). It was just easier than desoldering the whole board and putting a new one on.

I see this thread is pretty old, looking for some insight though. I have BrewPi legacy, followed all the instructions to add iSpindel to my BrewPi. I can see that its logging into the CSV but my BrewPi screen is blank.
Not quite sure what I did wrong, the instructions are pretty straightforward.
You could check if the brewpi container can access the csv file (is it mounted? what are permissions?)
Beyond that I’m afraid we’ve discontinued support for the brewpi and brewpi legacy software.
By now, BrewBlox has fully replaced both - and it has a plugin for the iSpindel at https://github.com/bdelbosc/brewblox-ispindel.
