How to test wind and rain sensors on Enviro Weather?

Hi,
I have the Enviro Weather station kit set up to send readings to Adafruit, I am getting data for all sensors except rain and wind speed. The rain sensor has not logged any readings and the wind seems to be sporadic.

Is there a way to test the sensors to see if they are sending data to the Enviro board? The reading files show a value of 0 which suggests to me that no data is being sent from the sensors.

Thanks,
Declan
