Power Pet PX2-WIFI Large Door Mount

In this power pet px2-wifi large door mount review, the verdict is simple: the High Tech Pet PX2-WIFI is the best smart WiFi dog door for large dogs, and it lands at #4 of 9 in our 2026 guide. It is a motorized, app connected door for pets between 30 and 100 pounds, sold for $579.99. With 151 Amazon ratings at 3.9 stars, it is the most reviewed connected door on the list. Buy it if you want entry and exit notifications on your phone and a schedule that runs itself. Skip it if your door slab is thicker than 0.5 inches, because this model is built for door mount installation on standard thin doors only.

The day to day experience centers on the app. It connects quickly, sends real time notifications when your pet enters or exits, reports potential problems, and lets you set 24/7 access schedules from anywhere. Instead of a flap your dog pushes with its nose, a motorized panel slides under its own power, so there is no drafty opening and nothing a stray animal can push through. A steel dead bolt locks automatically when the panel closes, and an anti pinch retract system reverses the panel if it meets an obstruction. The 100 pound capacity covers most large breeds, while the 0.5 inch maximum door thickness and plastic frame keep the unit light enough for a simple install. The one requirement is genuine High Tech Pet MS-5 ultrasonic collars, which is what triggers the door and keeps the warranty valid.

At $579.99, this Power Pet door is the premium pick in the guide, about what you would pay for a mid range wired electronic door plus smart features you cannot add later. Nothing else on the list pairs app notifications, 24/7 scheduling and a motorized panel for 30 to 100 pound dogs, which is why it earns the best smart door label. However, 3.9 stars across 151 ratings signals mixed owner experiences, so this is not a flawless door. If you want to know the moment your dog goes out or comes back, and your door slab measures under 0.5 inches, this is the one to get. Measure the door before you order, because the 0.5 inch limit is the one spec that rules this model out.
