CS107S PIR Ceiling Sensor Configuration

Video Tutorial

Watch the companion video V30: Configuring Switch Settings for a visual walkthrough.

Overview

The CS107S is a PIR (Passive Infrared) ceiling sensor that provides motion detection and photocell functionality. It can control a group of lights and includes a relay for direct load switching. This article covers adding, configuring, and associating the CS107S sensor.

CS107S Features

Feature Description
PIR Detection Detects occupancy via body heat
Photocell Measures ambient light levels
Relay Output Direct load control capability
Hold Time Configurable duration
Sensitivity Adjustable detection range

Where Ceiling Sensors Appear

Ceiling sensors appear on the Switches page within Discover in the app, not the Lights page. This is because they control lights rather than being lights themselves.

Adding a CS107S Sensor

Step-by-Step Instructions

  1. Navigate to the Discover page, then tap Switches.
  2. Tap the + button in the upper left corner.
  3. The app begins searching for nearby sensors.
  4. Put the CS107S into pairing mode (per installation instructions).
  5. When the sensor appears, tap to select it.
  6. Add the sensor to your zone.

Configuring the CS107S

Step-by-Step Instructions

  1. On the Discover page, tap Switches, then tap on the CS107S sensor.
  2. Tap the Settings button in the upper right corner.
  3. Configure the following:

Basic Settings

Setting Action
Name Enter a descriptive name
Rated Wattage Set wattage for relay output load
Group Association Select which light group to control
  1. Tap Next Step to access sensor parameters.

Sensor Parameters

Parameter Description
Hold Time How long lights stay on after motion stops
Photocell Enable Turn ambient light sensing on/off
Photocell Threshold Light level below which sensor triggers
  1. Tap Save to apply settings.

Photocell Behavior

When the photocell is enabled:

  • The sensor measures ambient light levels
  • Lights will not turn on unless ambient light is below the threshold
  • Even if motion is detected, lights stay off if the area is bright enough

This prevents unnecessary energy use during daylight hours.

Enabling Group Linkage

After binding the sensor to a group:

  1. Navigate to the Groups page.
  2. Find the associated group.
  3. Enable Linkage for that group.
  4. If linkage was already enabled, disable and re-enable it.

This ensures the group receives the correct configuration from the sensor.

Configuration Checklist

  • [ ] Add sensor from Switches page
  • [ ] Rename sensor descriptively
  • [ ] Set rated wattage for relay load
  • [ ] Associate to light group
  • [ ] Set hold time
  • [ ] Configure photocell (enable/threshold)
  • [ ] Save settings
  • [ ] Enable group linkage

Troubleshooting

Issue Cause Solution
Sensor not appearing Not in pairing mode Re-enter pairing mode
Lights not responding Not associated to group Check group association
Lights on in daylight Photocell disabled Enable photocell
Lights won't turn on Threshold too low Increase photocell threshold
Linkage not working Group not configured Enable/re-enable group linkage
