@PeeBee, I'm sorry to say that this counts as "user error". …
In my defence I did say "partly my fault".

Actually such a mistake is only possible in the TiltPi client because it takes comma-delimited lists as input for calibration. And you need to figure out calibration requires delimited lists 'cos no official document tells you this. Reading posts like this is where you find stuff like that.

And … my post was really a "public information" post for another reason; I bet there are misguided people who read this thinking "that's wrong, my Tilt measures 0.1C increments, not 0.5C". I think I was one of them for a while.


BTW My pycnometer bottle (25ml) arrived yesterday. I think I'll start a new thread for that once I've got it calibrated. 25ml requires a fairly reliable scales that can measure grams to 2 decimal digits. The little eBay ones we might use for water treatment salts, for about £10, are not up to the job (they fall over on "repeatability" returning different values weighing the same item), the bigger items (x2 or 3 the price) that the "vaping mob" use seem okay (I got one) otherwise use a bigger pycnometer bottle. The olden day guys used to weigh entire casks!

@PeeBee

Thank you.

I appreciate your efforts, even if I am sometimes clumsy in my phraseology.

Information - as well as entertainment - is why I, for one, come to JBK's Forum.

I have taken loads of useful information from here and continue to do so.

Long may it continue.

PS I hope I have contributed to the learning of some members too.

As promised, I posted up my pycnometer musings here: viewtopic.php?f=6&t=82494&p=850237#p850237

Update:

I had to reinstall my "TiltPi" software because it would not connect with the Tilt anymore. Was an excuse to upgrade to the new (Feb 2020) software which cured the problem … for now (connectivity is still dodgy at times).

A recent (current) brew produced the following:

I'd given up with the false configuration for water to allow for the anticipated accumulation of errors, but this beer is being fermented with a notoriously heavy cropping yeast (Wyeast "West Yorkshire") and I know the Tilt is overreading at 1.017. I think a compromise is in order; instead of purposely recording water's SG as "0.997", record it as 0.999. I'm convinced the Tilt cannot be reliable for FG but not attempting any compensation just leads to anxiety when the Tilt does decide to start reading high for final gravities! (This graph is showing a FG of 1.017, which is unexpectedly high, but more likely erroneous).

The FG will be tested by reliable means eventually. i.e. Do not rely on Tilt for a FG reading (but it is great for trend readings).

Beersmith (the recipe builder I use) will now import the results put out to the cloud by TiltPi. I'll be giving that a spin next …
