Zooz ZSE41 800LR Z-Wave Long Range Open/Close XS Sensor

D1 Local Only — Speaks only to hardware you control.

The unplug test

Nothing changes, because there was never a Zooz cloud to unplug from. The sensor reports open/close state over Z-Wave directly to whatever hub the owner set it up with; if that hub is a local one (Home Assistant, Hubitat), the whole chain from magnet to automation never leaves the house. Losing your home internet connection has no effect at all — only losing the hub itself would.

Why this tier: Contains a Z-Wave radio (FCC ID 2AZ2V-ZSE41) but Zooz operates no cloud service, app, or account for this product at all. It pairs only to a Z-Wave hub the owner supplies and controls (Home Assistant, Hubitat, SmartThings, HomeSeer, Vera, or Zooz's own Z-Box), and the manufacturer's own manual states no Zooz account or internet connection is needed for any of it.
