Offset for humidity. **solved**

Hi everyone,
Does anyone have an idea how I can add an offset to the outside humidity on a Nano SD? Mine never goes above 98%, even when it is very misty. I'd like to add an offset of +2% but there is no option to do this. As I use an Envoy, I can't do the offset on the console itselves...
Regards,
Koen

StationTab -> bottom block
If hum-sensor measures between 0.0 and 98.0 fill in as in example.

Hi Wim,
Thanks for your suggestion. I know, this is indeed for sensors which cannot provide a humidity above a certain value. I'd rather prefer to set an offset like we can with the temp. Otherwise, the graph jumps from 97% to 100% as the 98% is seen as 100%.
Hopefully, Boris will add this feature too soon.

No the range the sensor can provide, in your case 00 -> 98
is stretched to 00-100
Example as a sensor returns measurements from 40 to 60
Then 40 becomes 00
50 remains 50
60 becomes 100.
So the low value -> zero
The high value equals -> 100
And all values in between those two are
recalculated.

Really? I didn't see it that way. Great! That does also the trick! Thanks for pointing me to this.
Kind regards,
Koen
