PETLIBRO Granary 2 Smart Feeder
A five-liter dry-food feeder with app scheduling and a bowl-weight feature. Backup behavior, kibble shape, and scale upkeep are the practical buying differences.
Who it may suit
A cat or small-dog owner who wants app access and bowl-weight information, uses suitable kibble, and can place the unit on a flat hard floor.
Who should look elsewhere
A wet-food household, a pet eating oversized or irregular kibble, or a buyer expecting the scale to independently prove that a specific pet ate.
In-depth buying review
A practical candidate for a cat or small dog eating suitable kibble on a hard, flat floor, if you value app connectivity and bowl-weight data and can follow the maker’s upkeep guidance.

Scheduling and outage behavior
The iOS and Android app connects over 2.4 or 5 GHz Wi-Fi. Each dispense is limited to six portions; one portion is approximately 20 mL or 10 g, with weight varying by kibble. PETLIBRO says stored schedules continue when the network is offline, though remote app control is unavailable. Separately, it specifies up to 24 hours of outage use for the rechargeable backup and says scheduled feeds and Wi-Fi continue on that battery. These are manufacturer claims, not hands-on test results.

PETLIBRO specifies a five-liter dry-food hopper, not wet food, and regular kibble sized 2–15 mm. It cautions that irregular cubes and crescents may be unsuitable even within that range. The feeder is designed for cats and small dogs on a hard, flat floor rather than carpet.
Sources: Hopper and food type · Kibble-size limit · Intended settingWhat the bowl scale tells you
The scale tracks bowl weight and eating activity, with a stated maximum load of 7.5 kg. Those documented readings can provide bowl and activity information, but this review would not treat them alone as proof that a particular pet ate. PETLIBRO recommends recalibrating the scale after disassembly.
Sources: Bowl scaleCare and footprint
Only the stainless-steel bowl and holder may be washed; electronics beneath the holder should be wiped. PETLIBRO uses two desiccant bags together and recommends replacing them every 14 days. The body measures 357 × 180 × 356 mm and weighs 2.99 kg.

Does it work with irregular kibble that measures 2–15 mm?
PETLIBRO says it accepts regular kibble in that range, but irregular cubes and crescents may still be unsuitable.
Sources: Kibble-size limitDoes the bowl scale confirm which pet ate?
The documented feature tracks bowl weight and eating activity. Those readings alone should not be treated as proof that a specific pet ate.
Sources: Bowl scaleWhat happens to app control during an outage or network loss?
PETLIBRO says scheduled feeds and Wi-Fi continue on the rechargeable backup, specified for up to 24 hours of outage use. When the network is offline, stored schedules continue but remote app control is unavailable.
