(Note: IT is not recommended to put the sensor outside to detect the rainfall as condensation that naturally forms due to humidity may cause false alarms.)
2. Does the sensor package include a Sub-GHz Hub? Do I need to buy a separate hub to work with the sensor?
The sensor package doesn’t include a hub, so it’s suggested to buy a hub separately to work with the sensor. Tapo smart hubs: https://www.tp-link.com/home-networking/smart-hub/
3. How many Tapo T300 sensors can connect with one hub? Can the T300 connect to multiple hubs?
Up to 64 sub-g sensors/switches can connect to one hub. A Tapo T300 can only connect with one hub.
4. How do I reset and resync the sensor with a new hub?
Reset: press and hold the control button for 5 seconds until the LED on the Hub is blinking green.
To Connect Your Sensor to the Hub, Follow this FAQ: https://www.tp-link.com/support/faq/3118/
5. Does the Tapo T300 support other brands' hubs?
No, the Tapo Smart Water Leak Sensor will only connect to the Tapo App via a Sub-GHz compatible hub and is not compatible with similar low-energy protocols such as Zigbee or Zwave.
6. What to do if the sensor fails to turn on after the control button is pressed for 5 seconds?
Please open the rear cover of the battery to check whether there is any insulating strip stuck or left in the battery and make sure the battery is properly installed.
If the sensor still fails to turn on, please remove the batteries and put them back in again.
7. Can the sensor still work without being configured via Tapo App?
Yes, even though the sensor is not installed via the Tapo app, it will still sound an alert when a water leak is detected. However, if the sensor is not installed and associated with the hub, it cannot be managed or controlled via the app.
8. Does the sensor support remote control and monitoring through the TP-Link cloud servers?
Yes, once the sensor is installed and paired with the hub via Tapo App, you may control it remotely on the Tapo App.
9. What’s the expected battery life of the Tapo T300?
With two replaceable AAA batteries, the sensor can last up to 1.5 years while coordinating with 24/7 Tapo Hub alarms. (Battery life of up to 1.5 years is based on TP-Link’s laboratory testing triggering 3mins alerts per month. Actual battery life may vary based on device settings, use, and environmental factors.)
10. Does the sensor support battery display or low battery notification?
Tapo T300 doesn’t support a battery status display, but a low battery reminder and a battery level indicator with one bar remaining will pop out when the power is less than 20%. So, please remember to replace the battery as soon as the low battery notification appears to ensure the sensor can function properly and without interruption.
11. Where to buy extra batteries for the T300?
Any common AAA/LR03 battery on the market is supported.
12. What depth/conditions are required to trigger the alarm?
The alarm will sound once the water level exceeds 0.5mm when the sensor is laid flat on a horizontal surface.
13. How does the sensor sound an alert when a water leak or drip is detected?
Once the water leak or drip is detected, the sensor would alarm you immediately and will keep alerting you until stopped manually or the water leak is solved. If the sensor is synced with a hub and a smart action is created, the hub will use its alarm to also notify you. It’s suggested to stop the alerts on both the sensor and hub separately if you receive a water leak notification.
14. How should we cancel the water leak alarm manually and when not at home?
For the T300 Sensor: press the control button for 1 second on the sensor or click on the Clear Alert option in the Tapo App, as seen below:
For a Sub-GHz Hub: Press the sync button on the hub or click on the bell (
) icon in the Tapo App as seen below.
15. How to make the sensor return to monitor mode after being manually stopped?
After we stop the sensor alarm manually, the sensor won’t return to monitor mode until the water has dried or the water leak is solved. Thus, please remember to clean the water stains on the sensor after stopping the alarm to avoid false water leak detection and ensure the next alert can be triggered successfully.
16. What to do if the sensor’s alarm volume gets lower after working for a period of time?
1) The alarm sound would be diminished if the buzzer is covered or submerged in water. Instead of leaning the sensor against a wall, it is advised to install and position the sensor with the buzzer facing outward.
2) In order to extend the range of alarm transmission, it is best to pair the sensor with a hub and set the smart action for the sensor to ring the hub when a water leak or drip is detected.
3)Please refer to Q8 to adjust the sensor’s alarm volume.
17. How to adjust the sensor’s alarm volume?
Method 1: Double pressing the control button will cycle the alarm volume level through High, Normal, Low, and Mute.
Method 2: Open Tapo App, go to sensor’s device settings, click on ‘Alarm Volume’, and select your volume levels as seen below.
18. How to Set Smart Action for the T300 Sensor?
If you want the hub alarm and sensor alarms to alert you simultaneously, we must set a smart action for the hub and sensor to ring the hub when a water leak or drip is detected. The sensor can also cooperate with other devices in a smart action. There are two ways to set smart action for the sensor:
Method 1: Open Tapo App, Tap on the T300 sensor, click ‘Explore Smart Actions’, and choose a smart action type to set.
