Why it matters
The app locks or unlocks the door remotely, sets schedules and sends notifications over 2.4 GHz Wi-Fi. Pets enter with a collar key, or on the Medium size with a paired microchip (FDX-B, FDX-A, AVID types). Medium suits pets to 25 lb (7.1 x 7.8 in flap), Large to 100 lb (11.9 x 16.1 in). Power is batteries (C-cell medium, D-cell large) or an adaptor.

Limitations to weigh
- Measure your dog's shoulder height and widest point; the flap top should sit at least an inch or two above the shoulder, and the step-over should be low enough for seniors and short legs.
- Electronic doors need fresh batteries or power to stay locked or open as intended; check what happens in a power cut and keep spares.
- Door and wall installs mean cutting; check for wiring and studs in walls, metal or glass in doors, and rental rules before you start.
