I have been having the same problems as everyone else. The dang 780 doesn't give me near enough insulin for food. It halves it. I go high within a hour after eating and stay there for several hours before it starts to come down. I am sent low through the night and it just doesn't seem to be working. A few times I thought it was my site not working. That is what the slope on my cgm looks like. My graph looks like Mount Everest. Staying high for hours is unacceptable IMO. Medtronic has got to make it safer for people to transition over to the 780. This is NOT SAFE!!!!!!
Hey Dee - you've maybe read my posts in other social media accounts about my trial with the #780G (I started on it back in April - but had been trialing the #770G where AutoMode was horrible for me - so kept it in Manual).
I finally have been heard by Medtronic Canada (they're looking into some weird scary situations while I was on holiday - where the pump went slightly wonky) - but I also attended a virtual meeting last week for those of us new to the 780G or wanting to learn more if they're already on the fence post about upgrading. It was excellent, and I learned some new things. A few days later after that virtual meeting, saw not just one but TWO CDE's at my local hospital. Since being on the pump trial back in September, even with requesting help, I've been on my own learning about the pump (thank goodness for forums like this right?).
Main thing, I've got the pump set up correctly. A few tweaks were made - and since then - my blood sugars very rarely have gone above 10 (I have always been tightly controlled - part of the OCD in me). So, maybe best to seek out some advise from your CDE's? I know for myself, it's taken almost 2 months for the SmartGuard (SG) to get to know me, even with my going into Manual Mode.
One thing, what is your ISF (I had to change mine), I:C (I had to change mine slowly as I tested out the system). Other than that, with the algorithm, changing your basal rates won't make any difference. And remember, make sure the basal set up when you're out of SG - should be tested out properly to ensure you don't have whacky blood sugars if bumped out of SG.
I noticed you're in Canada too like myself (I'm an expat - so have a thing for Diabetes UK) - but now live in Ontario!
