Cat Mate Elite 355
$50 under your budget
Two sources call it the budget pick: microchip-selective entry, a programmable curfew, and an LCD naming the last pet through — for $100, no app or hub.

■ The catch — co-equal billing, always
It stops at about 13 lb. That's cats and very small dogs only — the lowest size ceiling of any door here. There is no app, no notification, and no remote lock: what the LCD shows you at the door is all you ever get.
Dealbreaker? Runner-up №2 raises the ceiling to ~40 lb and adds the app ↓

Traps — this verdict avoids
The 40-pound wall
No microchip-reading door exists for large breeds. The flaps cap at 13-15 lb, and the biggest one tops out at ~40 lb. Above that it's RFID collar keys, a motorized Power Pet, or Wayzn — nothing else. We size every pick against its stated ceiling.
The app is a second purchase
Connected SKUs carry a $50-150 premium over the same door without Wi-Fi, and SureFlap's app needs a separately-sold Hub on top of the $255 door. Every app model also needs a 2.4 GHz SSID — 5 GHz-only and mesh setups fail.
The hole is the hard part
Wall installs need a tunnel kit sold separately plus cutting through studs and siding — budget $100-300 for a contractor. Motorized doors also need mains AC at the opening, and Wayzn only clamps to a sliding-glass-door track.
