Yes and no. I have one unit that insists its in hawaii....not idaho. Could never fix it. Owner said he could care less as long as it works when power fails
The only issue I've had similar to yours is when I've had a unit with a very week signal strength that would occasionally drop out. When the wifi is lost, the unit converts back to GMT. So it would exercise 8? hours (not going to bother to look up that time zone!) ahead of when it was set for.
When the signal came back, the unit self corrects.. all normal as per Generac.
