<![CDATA[DHT22 and DHT lib]]>Hi
I'm new to version 2.x, has done sensors/gateways to version 1.x system. So I restarted myself in using version 2.x. Made the IDE installation on WIN10 via Windows store, and downloaded the mysensors 2.3.1 via IDE - works great!.
For starting I found https://www.mysensors.org/build/humidity just for testing that the enviroment are working, discovered that the DHT lib is not part of mysensors anymore, found it ( https://github.com/mysensors/MySensorsArduinoExamples/archive/master.zip) as the old lib and added this.

But I get a number of compilation error e.g.:
"undefined reference to `DHT::getHumidity()'"

So it seems that I'm using a wrong DHT libary version, I was looking at github - but it seems already to be converted to MuSensors version 2.x

Strange ... hope someone can pinpoint me to the correct libary

I wrote an updated version that uses the standard dht adafruit library.
I posted on github site (https://github.com/cnerone/MySensorsArduinoExamples/commit/922cdaaff772db3a59aef8d784d4ef4e43c9a50a) but its pubblication it's still in progress...
I run it for one year and it runs very good with no issues...

Yes I'm using the script you link to, but compiling it tell that it can't find DHT.h, so I was looking for the DHT libray, It seems that this library is not part of MySensors 2.x download when you from the IDE install library's.

I'll see if I can give you a link. I tried it yesterday and it works
