Humidity with DHT22: unit in % instead of °C

[resam]

I connected a DHT22 sensor to my DuetWifi and I'm using [c]M305 P104 X401 T22 S”Humidity"[/c].
Currently DWC shows: [c]Humidity 27.6 °C[/c], which I guess should be a relative humidity of 27.6%.

Is there a way to specify the unit for display?

New owner of Duet Wifi here. Insane board, I´m coming from CR-10S stock and I can´t hear those motors any more!!! Definitely will use Duet on my next printer.

I noticed that under "Machine Status" if I hoover mouse on "VIN" it reads voltage as °C. So there´s another unit to change.

This is already possible in the latest firmware version. DWC will parse the thermistor unit if passed explicitly. This is how I configure the humidity channel on my printer:

M305 P102 X401 S"DHT humidity [%]" T11
