This variant is not described in the manual. But I could imagine that it works. What I'm wondering is what the mower does when it wants to go back. I could test this next week on Sat.

Everything easily adjustable ... travels from one lawn to another

Unfortunately, the two zones are completely separate, i.e. the robot must be carried to zone 2, as one zone is located in the south and the other zone in the north of the house.

Are your two zones linked by a passable path for a lawnmower? I also have two zones at home and I've created a virtual "bridge" between the two and it works great!
