I’m far from an expert, but when there is a drop off or a spike, what are the values coming in from the station during that time, from the View Log File entries?
I wonder if the station is sending acceptable numbers or if WD is just displaying what it gets fed?
I appreciate your followup so we might know and learn from other’s experiences. I’ve found stuff and answered my own questions to try to close the loop. Thanks for your comment on what it seemed to be.
