HS-LS100+ User Guide

Installation and setup guide for the HS-LS100+ Z-Wave water leak sensor


HS-LS100+ is a compact, easy to install leak sensor. It is designed to control other Z-Wave devices directly or it may be used with a variety of Z-Wave certified home controllers to launch automation events or scenes.


  • Use to activate Z-Wave devices such as sirens or water valve controllers when a leak is sensed.
  • Use to trigger home automation events (aka scenes”, “automations or robots”) when a leak is sensed


HS-LS100+ is battery powered and includes a Z-Wave network button, LED indicator and a magnetic wall mount/wired probe assembly. The unit may be deployed as a free-standing sensor (using built-in probes) or as a wired remote sensor (via the wall mount/wired probe assembly).

Physical Installation

  • Free-standing installation Simply place the leak sensor on a flat horizontal surface in the area where a leak might occur.
  • Remote installation Install the included magnetic wall mount/wired probe assembly in the location of your choice (using the supplied mounting hardware) and attach the HS-LS100+ to it by aligning the 3 probes with the 3 holes in the mounting bracket. Position and install the wired probe in the area where a leak might occur or where you wish to detect liquid.

Z-Wave Network Installation

Remove the back cover by rotating counter-clockwise and install 1 ER14250 battery (included) inside HS-LS100+. Include the sensor into your Z-Wave network using the instructions below. Then, replace the back cover.

HS-LS100+ may be included into your Z-Wave network as a secure device or as a non-secure device. Use the instructions below to include or exclude HS-LS100+ to/from your Z-Wave network. If your home controller supports S2 security encryption, the Leak Sensor may be added as a secure device to your network. If not, it will add as a non-secure device. This will not effect the functionality of the unit.

  • Secure Inclusion (recommended if your home controller supports S0 or S2 Z-Wave encryption)
    1. Put your home controller into Z-Wave inclusion mode.
    2. Press and hold the Z-Wave network button for 5 seconds, then release it. Wait for the inclusion process to finish.
  • Non-Secure Inclusion
    1. Put your home controller into Z-Wave inclusion mode.
    2. Quickly press and release the Z-Wave network button once. Wait for the inclusion process to finish.
  • Exclusion
    1. Put your home automation controller into Z-Wave exclusion mode.
    2. Quickly triple-press the Z-Wave network button. Wait for the exclusion process to finish.
  • Factory Reset (Use this procedure to reset HS-LS100+ to factory settings when the Z-Wave controller is missing or inoperable).
    1. Press and hold the Z-Wave button for 20 seconds. Release the button once the LED stops blinking and glows solidly.


  • Leak Sensor Operation
    HS-LS100+ is designed to transmit a Z-Wave command when liquid is sensed. It will also transmit another command when liquid is no longer sensed.
  • Shock Sensor Operation
    The shock sensor is designed to transmit a Z-Wave command when HS-LS100+ has been physically moved. This sensor is especially helpful in determining whether the unit has been removed from its mount or tampered with.
  • Battery Sensor Operation
    The battery sensor is designed to report battery level with a Z-Wave command every 43200 seconds (12 hours). If desired, HomeSeer users can adjust this interval (0-2678400 seconds) by accessing the settings on the Z-Wave tab of the root device.

Z-Wave Association Information

HS-LS100+ supports Group 1 association. Group 1 reports the sensors status and battery if running on batteries.
