Make sure the Motion Sensor is installed correctly.

My Motion Sensor is Too Sensitive

Pets may set off a Motion Sensor by moving through a room or getting on furniture.
  • Verify that the Motion Sensor is a model designed to ignore pets.
    • SMCMT03-Z - immune to pets up to 40 pounds
    • NEXT K85 SMA - immune to pets up to 85 pounds
    • XHS1-TY - immune to pets up to 85 pounds
  • Keep pets out of rooms covered by Motion Sensors or consider arming in Stay mode, which disables the Motion Sensors.
Curtains, blinds or other objects that move in a breeze may set off a Motion Sensor.
  • Check areas in front of fans, air conditioners, and heating vents for light, movable objects.
  • Make sure windows and doors are tightly closed.

My Motion Sensor Doesn't Detect Movement as Far Away as I Expected

To test the sensor detection area:
  1. Make sure there is no movement in the area for two minutes.
  2. Walk at the outer edge of where you expect the Motion Sensor to detect movement and see if the sensor is triggered.
When properly installed, the NEXT K85 SMA Motion Sensor should detect movement up to 40 feet away and the XHS1-TY Motion Sensor should detect movement up to 50 feet away. Make sure the Motion Sensor is installed correctly.

The Light on My Motion Sensor Doesn't Turn on When I Walk in Front of it

The sensor may still be detecting motion even if the LED doesn't turn on.
When the sensor is triggered (detects movement), it notifies your system and then goes to "sleep" for two minutes to conserve battery power. It won't detect further movement and the LED won't light during this time. Wait for two minutes and then see if the LED lights when the sensor is triggered.

NEXT K85 SMA Motion Sensor
For the LED to light, the LED jumper switch inside the sensor must be set to ON, which is the default setting. If you didn't change this jumper setting, the LED should light when the sensor is triggered. If you changed the jumper to OFF, change it back to ON. The ON setting uses more battery power, but you can still expect the battery to last for about three years.

XHS1-TY Motion Sensor
  • When the sensor is triggered (detects movement), it notifies your system and then goes to "sleep" for two minutes to conserve battery power. It won't detect further movement and the LED won't light during this time. Wait for two minutes and then see if the LED lights when the sensor is triggered.
  • The XHS1-TY does not have an LED jumper switch.

My Motion Sensor Won't Pair With the Hub (XFINITY Home - Automation Only)

  1. Make sure the Motion Sensor is close to the Hub when you start the pairing process.
  2. When you get to the step in the pairing process where you're asked if the sensor is ready to pair, make sure you've pulled the activation tab out of the sensor to activate the battery. Wait a few minutes for the sensor to power up before continuing with the pairing process.
If the sensor still won't pair, reset the Motion Sensor before you try pairing it again.
