Third Reality Door Sensor

Mounting Kit

Factory Reset

Long press the reset button (refer to Fig. 3 in the original document) for 3 seconds to factory reset the sensor and put it into pairing mode.

Mounting Your Door Sensor

1. Ensure the installation surfaces are clean and dry before installation.
2. Attach Part A and Part B with double-sided tape separately. Ensure the alignment marks on both parts face each other, and maintain a gap of less than 5/8 inches (16mm) when the door is closed.

Setup with Smart Bridge MZ1

The Smart Bridge (sold separately) enables your Zigbee device to become Matter-compatible, allowing seamless integration with major Matter ecosystems like Apple Home, Google Home, Amazon Alexa, Samsung SmartThings, and Home Assistant. By setting up your Zigbee sensor with the Smart Bridge, it transforms into a Matter-compatible door sensor, enabling local control through Matter. Third Reality also offers the 3R-Installer APP, which lets you configure Zigbee sensor attributes such as default-on behavior and perform firmware updates.

1. Ensure your bridge is already set up within your smart home system.
2. Press to open part A (refer to Fig. 2), install the batteries, and close the back cover. The LED indicator should flash rapidly in blue, indicating the sensor is ready for setup. If this sequence does not occur, long press the reset button (refer to Fig. 3) for 3 seconds to factory reset the sensor and put it into pairing mode again.
3. Press the pinhole button on the bridge to activate Zigbee pairing mode. The Zigbee blue LED should start blinking.
4. The sensor will pair with the bridge, and a new device will appear in your smart home app, such as Google Home or Alexa.
5. Optionally, you can install the 3R-Installer APP and set the open delay time via the smart bridge. Then, use the multi-admin feature in your smart home app to share permissions with the 3R-Installer APP.

Screenshots illustrating the setup process with the Smart Bridge MZ1 are provided in the original document. These typically show device discovery, pairing initiation, and device configuration within the app interface.

Setup with Third Reality Hub and SKILL

The Third Reality Hub (sold separately) allows you to control your device remotely via the Third Reality APP, making it a great option for smart home beginners or those without a system from major providers. Additionally, the Third Reality Cloud supports SKILL integration with Google Home or Amazon Alexa, enabling you to connect your device to these platforms. However, due to the potential for slow and unreliable Cloud-to-Cloud connections, it is recommended to use the Bridge solution if Google Home or Alexa is your primary smart home platform.

1. Ensure your hub is properly set up with the Third Reality App.
2. Press to open part A (refer to Fig. 2), install the batteries, and close the back cover. The LED indicator should flash rapidly in blue, indicating the sensor is ready for setup. If this sequence does not occur, long press the reset button (refer to Fig. 3) for 3 seconds to factory reset the sensor and put it into pairing mode again.
3. Open the Third Reality APP, press the "+" icon next to the hub, and select "Quick Pair."
4. The sensor will pair with your hub and appear in the Third Reality APP.
5. Optionally, enable the Third Reality SKILL in either the Alexa or Google Home app to enable Cloud-to-Cloud communication.

Screenshots illustrating the setup process with the Third Reality Hub and SKILL are provided in the original document, showing app interfaces for hub connection and device pairing.

Setup with Compatible Third-Party Zigbee Hubs

Third Reality supports integration with various open Zigbee platforms, including Amazon Echo with built-in Zigbee, Samsung SmartThings, Home Assistant (with ZHA or Z2M), Homey, and Hubitat. If you own any of these devices, you can pair the door sensor directly without the need for an additional bridge or hub.

1. Ensure your Zigbee Hub is already set up within your smart home system.
2. Press to open part A (refer to Fig. 2), install the batteries, and close the back cover. The LED indicator should flash rapidly in blue, indicating the sensor is ready for setup. If this sequence does not occur, long press the reset button (refer to Fig. 3) for 3 seconds to factory reset the sensor and put it into pairing mode again.
3. Open your smart home app and follow the on-screen instructions to begin the Zigbee pairing process.
4. The door sensor will flash and then turn red, indicating it has successfully paired with the Zigbee hub.
5. You can now use your smart home app to control the sensor (e.g., turn it on/off, though its primary function is detection).

Troubleshooting

1. Why can't my Echo discover the door sensor? It has a ZigBee hub built-in.
   • Reboot your Echo by unplugging/plugging it back in.
   • Set the door sensor into pairing mode by long pressing the reset button inside the device; the blue LED will flash rapidly.
   • Keep the door sensor near the Echo with the ZigBee hub built-in, then ask Alexa to "discover devices".
   • If it is still not working, factory reset your Echo, re-add it, then re-discover the device again, and then pair it with your Echo device again.
2. I have a SmartThings hub, do I need a special hub for the door sensor?
   • Enable the SmartThings Skill in your Alexa app and sign in to link your accounts on both platforms.
   • Go to the Devices tab in your Alexa app and add devices to sync your devices under SmartThings to Alexa: "+" icon (on the upper right corner) -> Add Device -> Other.
   • Create a routine for the door sensor and light switches in your Alexa app. You can use door open/close to trigger actions like turning lights on/off, or you can set an Alexa "custom message" when the door sensor detects a door is opened.
3. Why nothing shows up for devices or group on the Third Reality app? I am using a SmartThings hub.

   Because you are using Echo (Alexa APP) and SmartThings (SmartThings APP), it will bypass the Third Reality app. The Third Reality app is only required when you are using the Third Reality Hub (which is equivalent to a SmartThings Hub) and will show the device in the app.
