How to convert the mesured value into a wetness indicator ? 

1. leaf wetness = -18,2 * (raw_wetness/4096)+15
2. If the raw_wetness value is over 0,83 * 4096, the leaf wetness is considered as 0.

In case of communication error between the sensor and the Device, the device may report an error code that needs to be filtered.

Sensors	Code error
THr	999
Rain collector	No error code
Wind Speed Vortex	No error code
Leaf Wetness	No error code

In case of successive error code the device can be reboot remotely: How to reset a device trought a downlink message
