From Grif:
 
 ....From what I have read about the motion sensor it uses Group 1 for motion, Group 2 for dusk/dawn, Group 3 for low battery......
 
 Does anyone know if the TriggerLinc (Model #2421) has any group for a Low Battery?  The manual posted on the Smarthome Wiki makes no mention of this.
 
 Also, Grif, where was the info about the Motion Sensor located?  I didn't seem to find it on the Wiki.

Info can be found on the WEB site under 2420M.
 
 “Dusk / Dawn Sensor (INSTEON Software Required)
 Save energy by ensuring lights are off at dawn or turn your porch lights on at dusk with INSTEON Motion Sensor's dusk / dawn feature. When used with supported INSTEON software or an INSTEON automation controller, Motion Sensor can also be used as a dusk/dawn sensor. After it has been bright for 3 and a half minutes, Motion Sensor will send an Off command for its 'Group 2', which can be used to turn off lights and appliances or trigger a software event. Conversely, it will send an On command after it has been dark for 3 and a half minutes. 
 
 Low Battery Warning
 Get notified when it's time to change the battery. INSTEON Motion Sensor has 2 methods of indicating the battery life is low:
 •     LED double-flashes after motion is detected (even if LED is disabled)
 •     On command is sent to 'Group 3', which can be utilized with INSTEON software or an INSTEON automation controller”
 
 As far the 2421 goes I found no indication of low battery.
