HS-FS100+ User Guide

Installation and setup guide for the HS-FS100+ Z-Wave Indicator Light & Temperature Sensor


HS-FS100+ is a multifunction module that includes a temperature sensor, controllable buzzer and a port to connect optional external light sensor. It is designed to work with a variety of Z-Wave certified home controllers to launch automation events or scenes.


  • Use to trigger events based on changes in temperature
  • Use the built-in buzzer as an audible notification that triggers when things happen in your home
  • Use with included light sensor to trigger events when indicator lights on appliances turn on or off
    Example: Dehumidifier is full indicator turns on
  • Use with optional water sensor to trigger events when water is detected near basement walls, plumbing fixtures or appliances


FS100 is equipped with a Z-Wave network button (for inclusion/exclusion), LED indicator and micro USB connector for use with an AC power adapter (not included). A 3.5mm jack is also provided for connection to the optional wired light or water sensors. Z-Wave commands are used to transmit temperature, light and water detection data and to control the built-in buzzer.

Physical Installation

Install 3 AAA batteries (not included) inside FS100 and mount it in the location of your choice using the supplied double-stick tape, mounting plate and mounting hardware.

Z-Wave Network Installation

Use the instructions below to include or exclude FS100 to/from your Z-Wave network.


  1. Attach light or water sensor cable (if available). Put your home automation controller into Z-Wave inclusion mode.
  2. Press the Z-Wave network button on the front of the unit one time. Wait for the inclusion process to finish. This may take some time.


  1. Put your home automation controller into Z-Wave exclusion mode.
  2. Press the Z-Wave network button on the front of the unit one time. Wait for the exclusion process to finish. This may take some time.


(Use this procedure to reset FS100 to factory settings when the Z-Wave controller is missing or otherwise inoperable).

  1. Press and hold the Z-Wave button inside the sensor body for 10 seconds. If successful, the LED will flash 5 times.


Built-in Temperature Sensor

The temperature sensor is designed to transmit temperature data to your controller using Z-Wave commands every 60 minutes (on battery power). That interval may be changed when the unit is line powered. See the Z-Wave Parameters section below for details.

Light Sensor

The light sensor can be mounted over any indicator light and will notify your controller with a Z-Wave command and will beep 5 times when light is detected. Another Z-Wave command will be sent to the controller when light is no longer detected. This sensor will check for light every 60 seconds on battery power or every 400 ms on line power.


The built-in buzzer emits a single beep when activated with a Z-Wave command.

Z-Wave Association Information

FS100 supports Group 1 association. Group 1 reports the sensors status and battery if running on batteries.

Wake Up Settings

FS100 can be programmed to wake up and send its battery status based on the polling interval set. The polling interval is set to 12 hours by default when the unit is added on battery power. When on line power, wake up is not supported.

Wake up interval

Available settings: 6-1500 (minutes)
Default setting: 0 - A setting of “0” disables the regular reporting feature and requires the sensor to be manually woken up to send updates.
Default setting when added to HomeSeer systems: 12 hours


Important: Line-powered devices function as Z-Wave repeaters. If you’ll be powering FS100 with batteries, include it into your network ON BATTERY POWER to prevent it from repeating Z-Wave commands. This functionality would quickly deplete your FS100’s batteries.
If your home controller supports “S2” security encryption, the FS100 will add 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.
