- HomeSeer MS100 G8 Smart Motion Sensor
- CR123A Battery (pre-installed or included separately)
- Magnetic Mounting Base
- Mounting Hardware (screws and double-sided tape)
3. Setup
3.1 Powering the Device
The MS100 G8 offers flexible power options:
- Battery Powered: The sensor operates on a single CR123A battery (included). This provides a long-lasting, wire-free setup.
- Micro USB Powered: For a battery-free setup, you can connect the sensor to a standard micro USB adapter (not included), such as a phone charger. When powered via micro USB, the device can also function as a Z-Wave repeater, extending your Z-Wave network range.

3.2 Mounting the Sensor
The sensor comes with a magnetic base and mounting hardware for easy installation.
- Choose a suitable location for optimal motion detection. Consider areas like hallways, rooms, or entry points.
- Attach the magnetic mounting base to a wall, ceiling, or shelf using either the provided screws or double-sided tape.
- Place the MS100 G8 sensor onto the magnetic base. The magnetic attachment allows for easy adjustment of the sensor's angle to fine-tune its detection area.

3.3 Z-Wave Inclusion (Pairing)
To integrate the MS100 G8 into your smart home system, you need to include it in your Z-Wave network:
- Put your Z-Wave hub into inclusion (pairing) mode. Refer to your hub's instruction manual for specific steps.
- Activate the inclusion process on the MS100 G8 sensor. This typically involves pressing a button on the device. Consult the device's specific Z-Wave inclusion instructions (often a single press of the tamper button or a similar action).
- The sensor will communicate with your hub and be added to your Z-Wave network. The MS100 G8 supports S2 security for enhanced protection.
- Once included, the sensor should appear in your hub's device list. You may need to configure device parameters within your hub's interface.
The MS100 G8 is compatible with most major Z-Wave hubs, including HomeSeer, SmartThings, Hubitat, and Home Assistant. It features the Z-Wave 800 series chip and Z-Wave LR (Long Range) technology for extended coverage.

4. Operating the Sensor
4.1 Motion Detection
The MS100 G8 detects motion using a Passive Infrared (PIR) sensor. It not only signals when motion occurs but can also track when no motion is detected for a specified period. This allows for advanced automation scenarios, such as:
- Automatically turning on lights when motion is detected.
- Turning off lights or adjusting thermostats when a room becomes unoccupied.
- Sending alerts to your smart home hub or mobile device upon detection of activity.

4.2 Configuration Parameters
The MS100 G8 offers several configurable parameters to customize its behavior. These settings are typically adjusted through your Z-Wave hub's interface. Common parameters include:
- Parameter 12: Motion Sensitivity (Range: 1-8, Default: 4) - Adjusts the sensitivity of motion detection.
- Parameter 14: Motion Sense Command Enable/Disable (Default: Enabled) - Controls whether motion detection triggers commands.
- Parameter 15: Values for Basic Set Command (255 for motion sense and 0 for timeout, or vice versa) - Defines the values sent for motion events and timeouts.
- Parameter 16: Motion Timeout Command Enable/Disable (Default: Disabled) - Enables or disables commands based on motion timeout.
- Parameter 17: Enable Shock Sensor (Default: Enabled) - Activates or deactivates the built-in shock sensor.
- Parameter 18: Motion Timeout Interval (Range: 0-65535 seconds, Default: 30) - Sets the duration after which the sensor reports "no motion" if no activity is detected.
- Parameter 19: Motion Sensor Enable/Disable - Globally enables or disables the motion sensor function.
- Parameter 20: LED Activity (Options: Off, Flash when motion detected) - Controls the behavior of the LED indicator.
- Parameter 32: Low Battery Threshold (Range: 0-50%, Default: 10%) - Sets the percentage at which a low battery warning is triggered.
5. Maintenance
5.1 Battery Replacement
The MS100 G8 uses one CR123A battery. When the battery level is low (as per Parameter 32), you will receive a notification from your Z-Wave hub. To replace the battery:
- Carefully remove the sensor from its magnetic base.
- Open the sensor casing to access the battery compartment.
- Remove the old CR123A battery and insert a new one, ensuring correct polarity.
- Close the sensor casing and reattach it to the magnetic base.
- The sensor should automatically reconnect to your Z-Wave network.
If using micro USB power, no battery replacement is necessary.
6. Troubleshooting
6.1 Sensor Not Pairing with Hub
- Ensure your Z-Wave hub is in inclusion mode.
- Verify the sensor is powered on (check battery or USB connection).
- Try performing a Z-Wave exclusion (unpairing) on your hub first, then attempt inclusion again. This can clear any previous pairing attempts.
- Move the sensor closer to your Z-Wave hub during the inclusion process.
6.2 Motion Not Detected or Inconsistent
- Check the sensor's placement. Ensure there are no obstructions blocking its field of view.
- Adjust the sensor's angle using the magnetic mount for optimal coverage.
- Increase the Motion Sensitivity (Parameter 12) in your hub's settings.
- Verify that Motion Sensor Enable/Disable (Parameter 19) is set to enabled.
- Ensure the battery is not low.
6.3 Compatibility Issues with Specific Hubs
- HomeSeer: For HomeSeer systems, the Z-Wave Plus plugin and a 700 or 800 series Z-Wave controller are required for full functionality. If using an older plugin, an upgrade may be necessary.
- SmartThings: As of recent updates, official Edge drivers may not be available. The device might connect as a generic Z-Wave device without full motion detection functionality. Community-developed drivers might exist, but their functionality is not guaranteed.
- General: Always ensure your hub's firmware and Z-Wave drivers are up to date.
