>If you ate many hours behind like the graph seems to show maybe it displays as Off-Line.<
As mentioned (reply #149), my WU Manage Devices shows online, and my Current conditions shows offline with no sensor readings showing. On the other hand, in the History Summary, directly below the Current conditions, the sensor readings are current (usually, no more than 10 min off, where my VWS setting for Rapid Fire is 5 min). Further, the readings that PWS Monitor shows are likewise, current. With PWSM its simply the "Last Updated on" date/time that is off by about an hour. Perhaps Buffy help out with that issue?
To add further to the WU confusion, you are right about the graph, below the Summary sensor readings. I hadn't noticed that before. It also shows about an hour off. But as with the Summary sensor readings, the graph(s) readings when you hover over them are current. It looks like the times are relative to an earlier time zone, or something like that. In the WU settings, my "Home Location" is set and that appears to be the only thing that would externally identify the WU time zone. Now my VMS Station Settings do have a time zone setting that is set to GMT -6, Central Time (zero time zone offset). I would think the uploaded data contains the date/time that WU (and PWSM) uses. I just wish WU would let me know why they won't show my data on WunderMap and in their mobile app.
Thanks
