MAN-MACHINE INTERFACE (MMI)
S2 offers a push-button behind a tiny hole in the front-face of the device, as well as a LED right next to
it
3
. This man-machine interface provides access to a menu. In addition, it provides a handy shortcut to
factory reset the device
4
.
To factory reset the device, keep the button pressed for approximately 10 seconds until the LED
starts to flash. This is equivalent to selecting menu item #5.
Notice that the device also supports a power-cycle sequencing factory reset as detailed in section 6.1.
To enter the menu, press and hold the push-button for more than a second until you see three short
flashes followed by a sequence of one blink, pause, one blink, pause, etc. This indicates that you have
successfully entered the menu. With each short button press (less than a second), you advance
through the menu. For example, pressing the button once brings you to the second menu item, which
S2 indicates by two blinks, pause, two blinks pause, etc. Once you have reached the menu item that
you want to run, press and hold the button for more than a second to execute the selected item. The
exact meaning of each menu item depends on the particular device and may vary from firmware version
to firmware version.
This is the menu for Power Switch S2 running firmware version 1.03 and above

Menu Item #
Operation
1
ZigBee Commissioning: Network Steering
While in this mode a single press on the button instigates ZigBee Network Steering (“EZ-mode”). If the
device is on a network it will open the network for new devices for three minutes, otherwise it will attempt to
join an open network. If the network is already open, the device will close the network instead such that
repetitive presses toggle the network permit joining state. The LED is on, when the network is open for new
devices, and off otherwise.

ZigBee Commissioning: Finding & Binding
Instigates the ZigBee Finding & Binding procedure (“EZ-mode”) on an initiator or target endpoint. Target
endpoints will enter identify mode for three minutes. Initiator endpoints will query targets and create suitable
bindings to these targets. After leaving the menu in this mode, the first button press starts the selection of
the endpoint and each subsequent press (within half a second) increments the endpoint number. Once the
desired endpoint is reached, wait for the LED to blink the selected number of times. Then, press a single
time to accept the selection or wait for three seconds to cancel the command. The LED will blink one time
to confirm an affirmative choice, or two times to indicate the request has been cancelled.

ZigBee Commissioning: Clear Bindings
Clears bindings on an initiator endpoint. Select this menu item and leave menu mode. Afterwards the device
expects the selection of an initiator endpoint. The first button press starts the selection of the endpoint and
each subsequent press (within half a second) increments the endpoint number. Once the desired endpoint
is reached, wait for the LED to blink the selected number of times. Then, press a single time to accept the
selection or wait for three seconds to cancel the command. The LED will blink one time to confirm an
affirmative choice, or two times to indicate the request has been cancelled. This mode is active for one
round only. Afterwards the device reverts to mode #1.

ZigBee Commissioning: Set Device Role and Factory Reset
Selects the ZigBee device role for this device on the network, resets the remaining settings to factory
defaults and restarts the device. Select this menu item and leave menu mode. Afterwards the device
expects the selection of an option. The first button press starts the selection of the option and each

The high-voltage inputs of S2/S2-R do not count as an MMI feature.

The 10-second-press factory reset (equivalent to menu item #5) is available since firmware version 1.04.

Notice: Prior versions have different menu items. Only the factory reset command (menu item #5) is identical
across all released versions of the firmware.
