How to Set Up Third Reality Smart Presence Sensor R2 for Room Occupancy Automation

The Third Reality Smart Presence Sensor R2 is a powerful addition to any smart home, offering precise presence detection that goes beyond simple motion sensing. With its advanced mmWave technology, it can detect even subtle movements like breathing, making it ideal for room occupancy automation. In this guide, we'll walk you through the entire setup process, from unboxing to creating intelligent automation that responds to whether a room is truly occupied or empty.

Whether you're looking to automate your lights, HVAC, or security systems, the Smart Presence Sensor R2 provides the reliability and accuracy you need. We'll cover placement best practices, pairing with your smart hub, and how to configure automation rules for maximum efficiency. By the end, you'll have a fully functional presence detection system that enhances your smart home experience.

Unboxing and Understanding the Smart Presence Sensor R2

When you receive your Smart Presence Sensor R2, you'll find the sensor unit, a mounting bracket, screws, and a quick start guide. The sensor is designed to be compact and unobtrusive, allowing it to blend seamlessly into any room. Before you begin, ensure you have a compatible smart hub, such as the Third Reality Smart Hub Gen2 Plus or a Zigbee-based hub like Home Assistant with a Zigbee coordinator.

The R2 uses mmWave radar technology to detect presence, which means it can differentiate between a person sitting still and a pet or moving object. This makes it superior to traditional PIR motion sensors for occupancy automation. It also has a detection range of up to 8 meters and a 120-degree field of view, giving you broad coverage for most rooms.

• Check package contents: sensor, mounting bracket, screws, and manual.
• Ensure your smart hub supports Zigbee 3.0 for seamless integration.
• Familiarize yourself with the sensor's LED indicator: solid green means paired, blinking blue means pairing mode.

Choosing the Perfect Location for Your Presence Sensor

Placement is crucial for optimal performance. The sensor should be mounted at a height of 6 to 8 feet (about 2 meters) on a wall or ceiling, with a clear line of sight to the area you want to monitor. Avoid placing it near windows, air vents, or large metal objects that can interfere with the radar signal. Also, ensure the sensor is not directly facing a source of vibration, as this can cause false triggers.

For room occupancy automation, aim to cover the main entry points and seating areas. For example, in a living room, mount the sensor in a corner to cover the entire space. In a home office, place it above the desk to detect when you're sitting. The goal is to have the sensor detect presence regardless of the person's position, so consider the typical layout of the room.

• Mount at 2 meters height for best coverage.
• Avoid direct sunlight and heat sources to prevent false readings.
• Test the sensor's detection range by walking around the room after installation.

Pairing the Smart Presence Sensor R2 with Your Smart Hub

Before pairing, make sure your smart hub is powered on and in pairing mode. For Third Reality hubs, open the companion app and navigate to 'Add Device' or 'Pair New Device'. For Home Assistant, go to Settings > Devices & Services > Add Integration, and select 'Zigbee' to enable joining mode.

To put the sensor in pairing mode, press and hold the button on the side for 5 seconds until the LED blinks blue. The sensor will then search for a Zigbee network. Once the hub detects it, the LED will turn solid green, and you'll see the device appear in your app. In Home Assistant, you may need to name the device and assign it to a room for easier management.

• Ensure your hub is in pairing mode before pressing the sensor button.
• Keep the sensor close to the hub during initial pairing to avoid connection issues.
• If pairing fails, reset the sensor by holding the button for 10 seconds and retry.

Configuring Presence Detection Settings

Once paired, you can adjust the sensor's sensitivity and detection delay to suit your needs. In the Third Reality app, you'll find settings for sensitivity (low, medium, high) and a 'presence timeout' that determines how long after the last detection the sensor reports 'empty'. For most applications, a timeout of 30 to 60 seconds is recommended to avoid false 'vacancy' notifications.

The R2 also supports different detection modes: 'Occupancy' for continuous presence detection and 'Motion' for traditional motion events. For room occupancy automation, use 'Occupancy' mode to trigger automations when someone enters or leaves. You can also set up 'presence zones' in advanced hubs like Home Assistant, allowing you to define specific areas within the sensor's field of view.

• Set sensitivity to high for small rooms or low for large open spaces.
• Adjust the presence timeout to prevent rapid on/off toggling of devices.
• Use occupancy mode for automation, motion mode for security alerts.

Creating Room Occupancy Automations

The real power of the Smart Presence Sensor R2 is its ability to trigger automations based on occupancy. For example, you can set your smart lights to turn on when you enter a room and turn off when you leave. In the Third Reality app, create a new automation: select the sensor as the trigger, choose 'Presence detected' or 'Presence cleared', and then select the action, such as turning on your Smart Color Bulb ZL1 [A19].

If you use Home Assistant, the possibilities are even greater. You can integrate the sensor with other devices like smart thermostats, fans, or even your garage door. For instance, you could have the sensor detect when you're in the garage and automatically open the Smart Garage Door Opener. The key is to think about which devices you want to react to occupancy and create rules that enhance comfort and energy efficiency.

• Start with simple light automations to get familiar with the sensor's behavior.
• Combine presence sensor with smart plugs to control non-smart appliances.
• Use presence data to adjust thermostat settings for energy savings.

Troubleshooting Common Issues

If your sensor isn't detecting presence reliably, first check the placement. Ensure there are no obstacles blocking the sensor's field of view, and that it's not mounted too high or too low. Also, verify that the sensitivity is set appropriately for the room size. In large rooms, increase sensitivity; in small rooms, lower it to avoid false positives.

If the sensor frequently reports 'presence' when the room is empty, it might be picking up moving objects like curtains or ceiling fans. Adjust the detection mode to 'Motion' and increase the timeout to reduce false triggers. If you're using Home Assistant, you can also create a 'presence hold' automation that ignores brief detections.

• Re-position the sensor if you experience blind spots.
• Update the sensor's firmware via the app to fix bugs.
• Check Zigbee signal strength; add a repeater if needed.

Setting up the Third Reality Smart Presence Sensor R2 is a straightforward process that unlocks a new level of automation for your smart home. With precise occupancy detection, you can create seamless experiences that save energy and add convenience. Whether you're a beginner or an advanced user, the R2 is a valuable addition to your setup.
