No History Data from Tapo Temperature and Humidity Sensor? Fix Sensor Sync & Cloud Upload Issues

As an owner of the Tapo temperature and humidity sensor T310 or T315, not only can you observe real-time temperature and humidity within the app, but you can also review the historical data to understand the daily, monthly, and yearly changes.

How to export history data from Tapo temperature & humidity sensor

If you notice no history data recorded in the Tapo app, or the data stops uploading, the following tips may help resolve the issue.

1. Attempt to manually alter the temperature or humidity in the sensor's surroundings to observe real-time changes in the app. For example, cover the sensor’s top vent hole with your hand, or blow air towards the vent.

If nothing changes, you may have a connectivity issue between the sensor and the hub. Refer to the suggestions here to improve the sensor’s connection: How to improve the connection stability of my Hub and its sub-devices

2. Restart the router, wait for 30 minutes, then check if the data in the Tapo App has resumed normal recording.

3. Check if the router has any firewall or ad-blocker settings that might block access to TP-Link servers, preventing the hub from uploading data to the cloud. Disable or remove these settings, then monitor future data records.

4. Change router DNS to 8.8.8.8 and 8.8.4.4.

5. Restart the Tapo hub.

Notes:

1) Unuploaded history data will be deleted after rebooting the Tapo hub.

2) The Tapo hub should remain connected to the internet to upload and store Tapo T310/T315’s history data. Data from any power outage period will be lost.

Q&A

Q1: How to check the signal strength of the sensor

Go to Device Settings in the Tapo App -> Device Info -> Tap the signal icon to check the Signal Strength value (RSSI rate).

• Strong: more than -50 dBm
• Good to Average: between -70 dBm and -50 dBm
• Poor: less than -70 dBm

Note: the signal is too weak when it is less than -70 dBm, and it is likely to cause disconnection problems.

Q2: Will the placement of a Tapo Temperature & Humidity Sensor affect its normal operation?

Yes, improper placement can affect the sensor's performance and reading accuracy. Please avoid placing your Tapo Sensor in the following locations:

• Areas near direct heat or cold sources: Do not place the sensor close to radiators, air conditioning vents, windows, or heat-generating electronic devices.
• Poorly ventilated or enclosed spaces: Poor airflow in these spaces will lead to inaccurate sensor readings.
• Areas with frequent humidity fluctuations: Unless the sensor is designed for high-humidity environments, avoid placing it in bathrooms, kitchens, or other areas with frequent humidity changes.
