I am monitoring several weather stations but from time to time one of them fails and stops reporting for hours to days.
The WU plugin monitors the custom state "Current Observation Time" for each weather station device, which no longer updates if the station is not reporting. This is the only indication I have that the station has troubles (besides going to the WU website).
Could we setup a trigger notification in the plugin that notifies me when a station has not been updated for a certain number of hours?
