Now it is showing up but no data and with "DHT init: false". Pin is right, typ selection too. I have a model with a resistor on the little board. ?

Could you post the section of your firmware that recognizes the DHT sensor? In the weather radio header file it looks like this:
#include "DHT.h"
DHT dht(DHTPIN, DHTTYPE);

DHTPIN and DHTTYPE are definitions from config.h

Another issue I do have with the add-on and the module activation in apache2. sudo a2enmod weatherradio fails all the time.
"ERROR: Module weatherradio does not exist!" How does a mod looks like? I do have weatherradio.conf in the right place.

Hm, seems like it is not in the right place. Did you really place it under /etc/apache2/conf-available ?
