I have two keypads. The first is located in the same room as the base and its WiFi light is not illuminated (plugged in). The second is in the adjacent bedroom and it’s wifi light is illuminated yellow (plugged in). What’s the significance of this color? This bedroom also contains an alarm range extender.
Great question! The "network light" you see on the Keypad indicates how strong the Z-Wave signal is from Base Station to the Keypad. If the signal is good, this light will be green. If the signal is poor, this light will be yellow. In order to preserve battery and power usage, a green light will only appear for a short amount of time, whereas a yellow or red light will show constantly. I recommend double checking that the Alarm Extender is in a good range and communicating between the Base Station and Keypad.
