Same exact thing has happened to me..
Sad situation as I JUST bought a Yarbo, used off a guy moving into a 55+ community, to replace my dead Mammotion Luba 5000.
It was just purchased earlier this year, still under warranty (and warranty transferred). That said, I have only had it 3 days, it managed to mow 1/2 of my property, and today when I was headed back out to finish and check my mappings, I got the “no module detected” message, and no matter what I try (tried it all), it will not detect the mower, but DOES work and detect the smart module..
Annoying.. Ticket 107466 opened today..
@Yarbo-Forum I need this expedited ASAP please.. It’s peak season, and I am down to my push mower.
