This small button is design as emergency button for people who need to keep it close to them. In a single push of button, you could activate scene to alert someone by email, or activate an alarm or just directly control any Z-Wave enable lights or devices.
The Aeotec Panic Button is small in form factor but features all the functionality of larger Z-Wave remote controls.
The Panic Button can be the primary controller of a Z-Wave network if you do not have a Z Wave hub or it can be set up as a secondary Z-Wave controller.
