Commissioning Pushbutton
The commissioning pushbutton definitions provide a variety of simple functions to aid in deploying
devices in a network. The commissioning button functionality on pin 20 is enabled by default on
Smart Energy devices.
Button presses may be simulated in software using the CB command. CB should be issued with a
parameter set to the number of button presses to execute. (e.g. sending CB1 will execute the
action(s) associated with a single button press.)
Associate LED
The Associate pin (pin 15) can provide indication of the device’s network status and diagnostics
information. To take advantage of these indications, an LED can be connected to the Associate pin
as shown in the figure above. The Associate LED functionality is enabled by default in Smart
Energy devices. If enabled, the Associate pin is configured as an output and will behave as
described in the following sections.
Joined Indication
The Associate pin indicates the network status of a device. If the module is not joined to a
network, the Associate pin is set high. Once the module successfully joins a network, the Associate
pin blinks at a regular time interval. This is shown in the following figure.
Joined Status of a Device
The LT command defines the blink time of the Associate pin. If set to 0, the device uses the default
blink time (500ms for coordinator, 250ms for routers and end devices).
Diagnostics Support
The Associate pin works with the commissioning pushbutton to provide additional diagnostics
behaviors to aid in deploying and testing a network. If the commissioning push button is pressed
