Evermind includes three sensors — you can monitor one, two, or three appliances, depending on individual habits. The sensors connect to the Evermind network using built-in wireless Internet. No home Internet connection is required.

When a monitored appliance is switched on or switched off, Evermind recognizes the act of switching as an indication of activity. If an appliance is left on or off for longer than expected, Evermind can detect these periods of switching inactivity and provide alerts in times of potential distress.
