Can the Kress KR250E (EyePilot RTK) self-drive ~15m over a paved path between front and back yard?

Looking at the Kress KR250E (EyePilot RTKⁿ, vision + RTK) and I want to make sure it handles my layout before I buy.

My situation:

- Front yard and back yard are separate lawn zones.

- To get from one to the other, the mower would have to travel ~15 meters over a paved/tiled path (no grass on the path itself).

- The route is fairly winding, not a straight shot.

- Most of the path has gravel borders along the sides, so there are edges to follow.

- Path runs partly alongside the house (so I'm a bit worried about RTK signal there).

Two questions:

1. Is a 15m hard-surface transport path realistic for this thing? I know multi-zone with "passages" is supported, but 15m over tiles feels long. Does the EyePilot vision keep position on a featureless paved stretch, or does it tend to wander/get lost? Anyone running a transport path this long over pavement?

2. Home automation: I run Home Assistant. How well does the Kress integrate (Landroid Cloud)? Can I at least read state and trigger start/stop/return, even if zones are read-only?

If you think a pure-vision mower (Eufy E15/E18) or something like Segway Navimow / Mammotion Luba would handle this corridor better, I'm open to suggestions.

Happy to share photos and measurements if it helps. Thanks!
