Product Information
Full details
The Link2home Smart Alarm Door/Window Sensor (TK878) is designed for users seeking enhanced home security and automation. It offers a key benefit of reliable, long-range detection with Zigbee 3.0 technology, allowing it to integrate with other Link2Home devices for smart home automation, such as triggering lights. A potential caveat is that it requires a separate Link2Home smart alarm hub (L2H-SECUREGWAY) to function. This battery-powered sensor provides tamper protection and low power indication, ensuring continuous monitoring.

FAQs
What is the required hub for this sensor?
This sensor requires the Link2Home Smart Alarm Hub (L2H-SECUREGWAY) to function and connect to your smart home system.
How far can the sensor transmit a signal?
The sensor can transmit signals up to 80 meters in open field conditions using Zigbee 3.0 technology.
What kind of battery does it use and how long does it last?
The sensor is battery-powered and typically uses a coin cell battery (check packaging for exact type). It can last up to 24 months under normal usage conditions.
Can I use this sensor with other smart home brands?
This sensor is primarily designed for the Link2Home ecosystem and requires a Link2Home hub. Compatibility with other brands is not guaranteed and may depend on specific hub functionalities.
What does 'tamper protection' mean?
Tamper protection means the sensor will alert you if someone attempts to open its casing or remove it from its mounting location.
How do I know when to replace the battery?
The sensor features a low power indication that will alert you via the Link2Home app or hub when the battery needs replacement.
Can the sensor trigger other devices?
Yes, when integrated with the Link2Home hub, this sensor can be used to trigger other compatible Link2Home devices, such as smart lights or alarms.
Troubleshooting
Sensor not pairing with hub
Ensure the hub is in pairing mode and the sensor is within range. Check that the battery is correctly inserted and has sufficient charge. Try resetting the sensor if applicable and repeat the pairing process.
False alarms or frequent triggers
Verify the sensor is mounted correctly and the two parts are properly aligned. Ensure there are no obstructions that could be misinterpreting as an open event. Check for strong magnetic interference.
Low battery warning persists after replacement
Ensure the new battery is inserted correctly and is the correct type. Clean the battery contacts if they appear corroded. Re-pair the sensor with the hub after replacing the battery.
Sensor offline or not reporting status
Check the sensor's battery level. Ensure the sensor is within the Zigbee range of the hub. If using a Zigbee mesh network, check that other Zigbee devices are powered on and functioning as repeaters.
