I have been in contact with the developer of the Wilhelm Signalk app for iOS about its inability to display humidity properly; he says that according to SignalK standards the number should be a "ratio" and 46% humidity should be .464643630981 What Openplotter sends is SignalK is 46.4643630981.
It's possible he's the one who is mistaken. Thoughts?
(Seems like in a recent past version of openplotter I also saw numbers like 464643630981 without the decimal. )
I like his app a lot, but it is expensive.

He can choose to say the humidity is 0.46 or he can say 46%, he can't say it's 0.46% ..... hopefully he will use the commonly accepted terminology and say 46%

Because he is expecting it to be .65 he is multiplying x100 and then when displaying it on an "analog" gauge in Wilhelm SK app with range from 0 to 100 it is always pegged at 100.
I am not familiar with this usage of the term "ratio" but a percentage is generally stored in a database as a fractional number not an integer; .6500 and not 65.00.
Clearly for display on an instrument view it should say 65.00%; the question is what should SignalK be passing for this kind of number, so that various apps know what to do with it.

e-sailing has fixed this on signal k and openplotter code on 0.14.3. It may not work until a major update to update signal k code too.
Marking this as solved, thanks!
