This is probably going to sound ludicrous, but with the daylight savings time change today it made me wonder:
Can I trick my G4 into thinking I just inserted the sensor (even if I inserted it a week ago) by just changing the Date/Time on the receiver?
Since I won't need to test this out until 5 days from now, I figured I'd ask around if anyone ever tried this?
Why bother? Sometimes that 2-hour CGM gap comes at a very bad time (even if you've been warned all day that it is coming).
If it works, the only downside I can think of would be that it messes up your CGM data (for Dexcom Studio analysis) but it seems like an obvious workaround would be to upload your last week's data first and then change the date/time.
If I am the only G4-addict that has ever wondered about this (I've been using my G4 since January and didn't think of this until this morning) then it probably means I am WAY too reliant on my G4—and I already know that I am—but resetting a sensor is already sneaky, so why not gain an extra 2 hours as well!
I just feel so naked without my G4 for those 2 hours every week! :-)
funny how we get so attached to our CGM. Ihad to go 2 days w/o it, but reminded self that I went 41 years w/o it and 2 days was a piece of cake when put into perspective.
I just received my replacement G4 receiver this week. The first on is now one year old. I'm running both receivers so that I can "bridge the gap," once per week. I don't like that two hour blackout either. Maybe I am too dependent, but I like the info it gives; it keeps me out of trouble.
I did the same thing with the 7+ system. When I start a new sensor the data is kind of wacky and hyper. It's not that useful having a second receiver for that 2-hour gap. But the jump from the first to second week is great to get the extra data.
The Dexcom receiver has both an 'internal' time, and the 'display' time based on the user setting. The internal time is probably GMT, set when manufactured. You can see the internal/display time when you extract the data. On Dexcom Studio, there is an option to 'ignore' Display time adjustments, and will show the true continuous trends on reports such as the Glucose trends
So the 2 hour wait time is based on the internal time, and you can't fool it !
As for the 2 hr wait during a 'bad' time... did you know you can do a Stop Sensor, then Start sensor, at a time that's convenient for YOU ? You will cut each 7-day time a bit if you do this stop/start early, but I think it's worth it to pick the time that works best for me. You can also check the time it was started, under the Device Settings, in case you're not sure when the 7-day time will end.
I like the way you think but even if we could defeat the 2 hour window, the sensor really does need all of that "wetting" time (and more) to achieve useful accuracy. I take the first 10 hours of readings with an extra grain of salt even as it is! (referring to my PLUS system)
I completely agree with you, Don... but this was just for after it's already been a week (and therefore has already been calibrated is always very accurate). I also am a lot more cautious the first couple days, but after 1 week (then week 2 & 3) it doesn't need that 2 hour gap at all!
Thanks for the tip on 'ignore' Display time adjustments with Dexcom Studio (I've never used that, but it could be useful for traveling and time zone changes).
I always try to fit the 2hrs/week into a "better time" than when it shuts down itself... but it never seems to be an ideal time :-) When I sleep would be the best, but then I have to wake up to calibrate it!
We have been able to get around it with two receivers. Caleb's first G4 was run over and the screen cracked, so we have a second. As long as I restart at different times, there is almost no blackout period.
So when you are able to upgrade, it might be worth holding on to the old receiver.
