Owners of smart pet-feeding device Petnet were told to “feed their pets manually” after a server problem stopped the device from working.

Petnet allows owners to schedule and control feeding via a smartphone app.

Adam Simon, an analyst with research company Context, said it was important users “always had a manual back-up” for smart systems.

“Increasingly, people are becoming dependent on these smart objects, and that could become a problem,” he said.

“In this case, your pet could be left hungry.”
