Stay Guardian by Engineer M8One package: smart access + privacy-first occupancy awareness
How it works

From booking to ready-for-next-guest, shown properly.

Stay Guardian uses one simple package: the connected lock box for access, Sense Guardian for occupancy awareness and one centrally placed EM8 Hub to bring the workflow together.

One connected journey

Follow the whole operational process

These are the steps the system supports for every stay.

2

Code scheduled

A unique PIN is created and activated only for the booking window.

3

Arrival detected

The lock-box event is paired with presence information to indicate that the guest has likely arrived.

4

Vacancy confirmed

After checkout, Sense Guardian helps show when the property appears vacant.

5

Cleaner released

The next step can begin only when the property is actually ready.
