iSpindle - DIY Electronic Hydrometer

[Tartan1]

is it with the calibration at different sugar levels

Yes you need to calibrate using the following directions https://www.ispindel.de/docs/Kalibrierung.html This should get you in the ballpark.

thanks
I just dropped it into my fresh wort (put into fermenter 2 hours ago0 and I get 1.051 on my hydometer and brewspy gives the reading from Ispindel as 1.027 ,so some thing is amiss.
I am going to let this one track the fermentation and I will log the reading and note the hydrometer reading at the same time.
that i think will give a few data points.
Then when this brew is done I will try the sugar calibration as above

You can easily use the readings you get from a ferment as your data points. But beware if yeast is all over the ispindel cap that will effect the readings.
However you will always get this occuring in a beer ferment. Less so if used in wine or mead.

I just built my ispindel with the WEMOS D1 Mini v4. I had the v3 but I broke the connectors when trying to resolder.

The v4 will flash and enable config mode. It will connect.

It seems to not send data updates after the first update - if the first update sends which is like a 20% chance. I am sending to Grainfather app.

I have seen that the wemos pro has a mod. Could this be the same? I wonder if it’s power related after sleep mode starts.

Anyone have suggestions or expertise to get the v4 to work?

What firmware are you using?
Gravitymon seems to support newer hardware better and has very good support from the developer @mper.

I used the latest from ispindel

Gravitymon has really nice documentation. It appears the v4 is not on the menu there as well. It also does not show capability with Grainfather.

I found a v3 on eBay and ordered that.
