Baby & Pet / chicken coop door

ChickenGuard All in One

D0 No Radio — No radio at all. It cannot phone home.

The unplug test

There is no router to unplug from in the first place. The door opens and closes on its own schedule or by ambient light level, set with buttons on the unit itself, running off 4 AA batteries, a solar panel, or 9V DC power. Nothing about it connects to your home network, a phone, or a vendor server, so there is nothing a vendor outage or a lost internet connection could take away.

Why this tier: The manufacturer's own product page describes a fully standalone automatic coop door: battery, solar, or 9V DC power, controlled entirely through buttons and a display on the unit itself, with a programmable timer or dawn/dusk light sensor. No app, WiFi, or Bluetooth is mentioned anywhere in the product page or FAQ, and no FCC grant for a radio was found under the brand name. It contains no intentional radiator.
