I succumbed to the lure of shiny new toys and invested in a preassembled, tested and calibrated ispindel :), which looks to work well. I have a RPi4 around on which I installed fermentrack. Sadly, the two do not like to communicate :(. They must have once as there is a solitary log entry ispindel :
'{"name":"Red","ID":5179882,"token":"fermentrack","angle":61.28779,"temperature":22.5,"temp_units":"C","battery":4.150157,"gravity":1.063814,"interval":9,"RSSI":-45}'

I am reasonably certain that the ispindel device works properly. If set to calibrate mode, and login on 192.168.4.1 to the ispindel network, and select info, the temperature and device angle in real time are displayed. So if you waggle it the angle immediately changes. When in the operating mode I can see the device on my router as ESP-4F09EA, so it can clearly access my home network.

The only other clue I have as to whats going on is the stderr error log which seems to indicate that its not listening :

Did you enter the raspberry pi IP address in the iSpindel settings?

If I remember correctly there is a spot to enter "fermentrack", no quotes, as the service type and IP address of pi fermentrack server in the iSpindel configuration menu.

Then I think you have to manually add a gravity device in the fermentrack menu and it should see the iSpindel.

Since my earlier post I have connected the ispindel to the Brew-Spy website, where it is happily charting the finish of my latest brew.

But I would much prefer to get fementrack connected as it offers so many other options. I've attached pictures of a couple of configurations I attempted. As I said above the connection to my wifi network is solid and its working with brewspy, connecting every 6 mins.

The fermentrack app shows that I have added the tilt sensor ok, but shows no readings.

Any further ideas much appreciated. Failing that any alternative softwares .. .

Best Regards

Your server address and path/uri appear to be the same. The path/uri needs to be the ip address of the iSpindel, http://xxx.xxx.xxx.xxx/ispindel, and server address will be ip address of pi.

This is what mine looks like

Thank you for the info and the setup image. I tried to find this out from the fermentrack website but it just says To Do.
I will give it another try when this brew is done.
Many Thanks

Best Regards
