Power Quality - 128X in Last 30 Days

How was your issue detected?:
I saw the Labs screen and the warning about the Power Quality. Not sure if this is something I need to be worried about? Should I have an electrician out to look at this? It is a new house (2 years old). What issues can this cause?

I have a second sense and its Power Quality looks the same.

Did you noticed any other signs of this issue around your home?:
We have very minor lights dimming but rarely. Nothing else that I have noticed.

I would have someone take a look. Dips that frequent are not normal.
