Automatic pet feeders require setting the clock first, then programming meal times and portion sizes through the control panel or companion app.
A mistimed feeding can have your dog eating breakfast at 3 AM or skipping dinner entirely — that’s why getting the clock right is the foundation of programming an automatic pet feeder correctly.
If you’re still choosing a feeder, our tested roundup of the best automatic pet feeders can help narrow the options before you start programming.
Programming an Automatic Pet Feeder: Controls and Setup Steps
Every automatic feeder shares the same programming flow regardless of brand. You start by setting the clock — this determines when meals actually dispense — then assign meal times and portion sizes. Button-only models use the front panel; Wi-Fi models like Petlibro let you do the same work through an app on iOS or Android. The table below shows how popular models compare on meal capacity and portion control.
| Model | Max Meals/Day | Portion Method |
|---|---|---|
| PetSafe Simply Feed 12-Meal | 12 | 1/8-cup increments |
| Petlibro Air (AF008) | 6 | Portion units (app or panel) |
| Nano Automated Feeder | 6 | Weight-based (UP/DOWN) |
| VOLUAS Feeder | 7+ | 1–40 portions per meal |
| CE Compass Large Programmable | 3+ | Portion units (Volume + Set) |
Step-by-Step Programming for Popular Models
Each model has its own button sequence, but the underlying pattern stays the same. Below are the exact steps for the three most common types.
PetSafe Simply Feed (12-Meal)
Unlock the screen by pressing center and up simultaneously. Press the right button to enter settings, scroll hours and minutes with up and down, then press right to confirm. Select “User Selected Meal” mode, then set the time and portion size for each of the 12 meal slots using the same scroll-and-confirm pattern. Hold the center button for 5 seconds to save and exit.
Petlibro Air (AF008)
Press Set/OK twice to enter settings. Set the hour with +/-, press Set/OK, set minutes, press Set/OK, then set AM/PM. Each of the 6 feeding plans gets its own time and portion — press Set/OK to confirm each one. Long-press Set/OK for 3–6 seconds after the last plan to return to the home screen. The Petlibro app mirrors these controls if you prefer a phone interface.
Nano Automated Pet Feeder (PetSmart)
Press CLOCK, use UP/DOWN to toggle AM/PM, press ENTER, then set hours and minutes with the same buttons. For custom meals beyond the first preset, press MEAL TIME, select meal 2–6 with UP, press ENTER, set the time, then adjust the food weight. Manual feed dispenses on demand with MANUAL FEED and ENTER.

What Are the Most Common Programming Mistakes?
Wrong time format. Confusing 12-hour and 24-hour mode causes PM meals to dispense in the morning. Double-check your feeder’s time format setting before saving.
Skipping the priming step. Conveyor-based feeders like the PetSafe Simply Feed need the motor primed after a refill — otherwise the auger jams. Press center and left together until the conveyor runs, then pour spilled kibble back into the bowl.
Overfilling portion sizes. The VOLUAS feeder allows up to 40 portions per meal, but overloading the chute causes blockages. If the dispenser jams, check the chute for food buildup and reduce the portion count.
Battery orientation errors. Match the outlines inside the compartment; reversed polarity stops the feeder cold.
FAQs
Can I program a feeder without Wi-Fi or an app?
Yes. Most automatic feeders — including PetSafe, Nano, VOLUAS, and CE Compass models — use button-only controls on the front panel. Wi-Fi and app features are optional conveniences on Petlibro and other smart models, never a requirement for basic programming.
How many meals can I schedule per day?
It depends on the model. Most budget and mid-range feeders support 6 meals per day. The PetSafe Simply Feed allows up to 12, and the VOLUAS feeder can handle 7 or more meal slots with up to 40 portion units each. Check your model’s manual for the exact limit.
What size kibble works in an automatic feeder?
Standard dry kibble up to about 10mm in diameter works in most feeders. PetSafe’s Simply Feed also accepts semi-moist food. Avoid large kibble, freeze-dried raw patties, or wet food in any standard dispenser — they cause jams and may damage the auger mechanism.
