thanks for the reply and the info. I wasn't aware of Weather Radio but it sounds very nice. We are using a BMP180, a DHT22, a MLX90614 and a photo resistor in the Induino Meteostation together with a PRO Trinket 5V. Maybe we can adopt the Weather Radio code to work with these sensors and the wind speed sensor

. If that doesn't work, I will just get a new set of sensors and give it a new try. The all sky camera seems very promising as well :-)
