Erica 29 (Fog Edition)

Erica is coming back to you from her vacation, and she does it in the form I think you like the most - covered in the fog!
There are only 2 little tricky moments including the break-in, the rest is kept to level 1*, so I encourage you to give it a try!
I hope you will enjoy and I would be really grateful for all the comments and ratings.

Normal sudoku rules apply.

Dynamic fog: The grid is partially covered in fog. Entering correct digit will clear fog from its cell and may clear fog somewhere in the grid. No guessing is required.

German whisper: Adjacent digits along a green line have a difference of at least 5.

X/V: Digits in cells joined by an X sum to 10. Digits in cells joined by a V sum to 5. Not all Xs and Vs are given.

Entropic: Any sequence of 3 adjacent digits along a peach line must have a low digit (123), a medium digit (456) and a high digit (789).

Entropic Line Explanation:

Basically, if one digit on the line is low, then every third digit will also be low; same applies for the remaining groups.
