Digging more into it, everything appears to be related to DST.
I’ve been talking to Sense employee James, Ticket # 323576
He has recreated and confirmed today displays as “yesterday” this week displays as “last week” and this month displays as “last month”. But has no timeline for when Sense will figure out how to fix it.
This thread is also related to the DST issue.
The “No data… this was your life pre-Sense.” message began appearing for all time period views when a device was not on. For some reason Sense was having issues loading the data for some time periods, hence the “pre-sense” message. For some reason this message only started displaying after DST.
My suggestion: The ‘Pre-sense’ message should to be reworded to simply “No data for this time period” with a tap link to a page describing the possibilities: Your device was not on during this time period, Error or failure to load data, Device not yet discovered, Life pre-sense, etc…
My ‘Heat 7’ somehow deleted (not merged) itself at the exact time I looked at the device. I did NOT manually delete it. No idea how it happened, but there is nothing anyone can do. Asking everyone to keep an eye out for devices that go missing or similar issues to know if this was a one off fluke/bug or something more widespread.
My monitor going offline at at 2:06 for 6 seconds was it automatically rebooting itself which apparently happens occasionally. So for those asking for an auto reboot feature apparently it is possible, but have no idea how, when or why it is currently used on the backend.
