Sigh, my pump just failed too. Went into blinking the home screen never to stop mode. My fault as it's one they already sent a replacement for because it was losing it's date (not programming) with every battery change. It was on it's way out.
I had programmed the new replacement one for using Novolog, had tried Novolog and still had a couple of pod failures. So I was being lazy and picked up my old one that I had been using with my Humalog. So now lol, I am trying the Novolog again and I had to change the settings by now in it anyways. We shall see what happens, because of so many pod/site failures I had switched to pump and MDI with my Humalog.
But gees, PDM/pump failure, my Libre was reading 80 points off, sometimes 50, sometimes 20. So I can't tell what it's doing. It still worked for what I was trending swimming on a shorter swim, but otherwise you can't trust it. I have more and they are replacing it. But I also restarted my Dexcom and it was being hugely inaccurate too for the first couple of days, all over, way too low, way too high. Lots of calibrating. I looked and I've had it on 32 days so it's past what they usually last for. But today it's seems to be reading great. I am on the Novolog and testing that again. So I seem to be all set. Knock on wood, because everything acting up at the same time was not fun and I must have went through 50 finger test strips. Between a PDM pump change, insulin change, 2 CGM's wonky, I even ended up with little dots all over my fingers yesterday I was testing so much!
I wouldn't do without the tech, but it certainly has it's own nuances!
