Meshify Defender Leak and Temp Sensors are powered by 2 Lithium AA batteries. The batteries are designed to last up to 5 years under normal operating conditions. These batteries are easily replaceable.

Low signal may impact battery life and sensor connectivity. To improve signal:

• Check the area for items that may block the signal, such as large metallic objects, refrigeration units, or areas with high signal interference (i.e. network closets), and make sure they are not between the sensor and the gateway.
• Move closer to the gateway and press the button for 2-4 seconds (or until you hear a beep) to recheck signal. Button will flash purple up to 40 seconds, followed by either:
  • Three beeps and green blinking light for good signal
  • Three beeps and blinking yellow light for ok signal
  • Long tone and red blinking light which indicates poor signal

• Remove the sensor cover by twisting the base until the unlock icon on the bottom of the sensor is aligned with the notch near it.
• Check that the batteries are inserted correctly, and contact points are clean (try rolling the batteries inside the battery compartment).
• Connect the sensor again by pressing the button for 2-4 seconds (or until you hear a beep).
• If batteries are still showing low, replace both batteries with two new Lithium AA size batteries, and reconnect the sensor.
• After replacing batteries, if you are still having issues, please contact Sensor Support for further assistance.

Note: Please do not use regular akaline or rechargeable batteries, which will cause the sensor to underperform.

• Press the button for 2-4 seconds (or until you hear a beep) and release the button to attempt connection. Button will flash purple for up to 40 seconds.
  • A long tone and red solid light indicates a failure to connect.
  • You can retry connecting by 1) moving closer to the gateway and/or 2) moving objects away that may be creating signal interference, and pressing the button for 2-4 seconds again.
  • If the sensor is still unable to connect, it will enter power saving mode. Please contact Sensor Support for further assistance.
• If the lights aren’t turning on, or the beep isn’t occurring, you may need to replace the battery
