[Equipment] O2Ring timestamps

[garyhibb]

We got the O2Ring for my wife (who has Resmed Airsense 11) and have been using it 3 nights so far. The O2Ring firmware version is 1.9.0 and we have ViHealth mobile app ver 2.74.53 to collect the data for forwarding by email to a PC (in both .pdf and .csv format.)

The first two nights of data look accurate as it matches my wife's notes that she takes during the night whenever she wakes up (for example when the cpap starts leaking.) The third night, the data shows start and stop times that are about 1.5 hours earlier than the actual times. The duration of the recordings is correct though, so it seems to be the right data but just 1.5 hours off.

Has anyone else noticed issues with O2Ring or ViHealth timestamps?

Did the battery happen to go completely dead at any point?

[garyhibb]

Thanks for response, Jeff.  No the battery has always been at least half full.

Yes My O2Ring has occasionally (not very often) gone off by an exact number of hours. When I spot that, I edit the name of the file before importing it to OSCAR, it's just the date and time in obvious numbers. As I reported about a fortnight ago..

Datetimes can also be fixed for O2 Insight, partially through a similar filename change, though the complete fix (so the right datetime appears in the report) requires binary (e.g. hex) editing skills.

The Developers of ViHealth, the official phone app for O2Ring, told me that there was no user-friendly way to fix data already imported to it. I bet there is a way, but it might be a bit too hacky for most people.

Given it's a recurring issue, and people need to be able to synch their data, I think the developers ought to provide a user friendly way of fixing datetimes, in both/all their relevant apps.

A couple of times it's been off by 8 hours. I've had to get in the habit of checking the ring's time before masking, and if it's incorrect I synchronize it with the computer. It's only been off a couple of times, but on one of those occasions the time changed during the night after I'd done my pre-check, and I didn't think to check it before I downloaded it. It's annoying that there's not an easy correction, but at least the file renaming before importing into Oscar works.

Thanks for your responses.

After uninstalling and reinstalling the ViHealth app, the times were correct.  Since then I've noticed the time displayed on the ring is sometimes off (by several hours).  As herenthere suggested, connecting the app and resynching with the ring via bluetooth seems to restore the correct time.

It would appear that you may have a defective O2Ring. If it is still under warranty, I would recommend that you contact the seller for a return or service,
