Unfortunately this cannot be recovered. The sensor data are saved to the hub, they are gone after the hub has been factory reset.

I thought that the Tapo advertising says that the temperature sensors get "2 years of cloud data logging" as per the info here:

https://www.tapo.com/en/product/smart-sensor/tapo-t315/

 

So is there a way to recover this seeing as I have onboarded the temperature sensor, back onto the same hub, using my same Tapo account e-mail address login?

Data stored in the cloud is linked to the device. If a hub is factory reset, that link is broken and the data cannot be recovered.

However, data can be recovered in these two reset scenarios:

1. A sensor is physically reset. When you re-pair it to the same hub under the same account, the app will prompt: “This device has been previously configured.” You can then choose to retain its historical settings and data.
2. A Hub undergoes a ‘soft reset’ (holding the reset button for 5 seconds). This reset only deletes WiFi information. When you reconfigure it with the same TP-Link account, you will receive the same “This device has been previously configured” prompt and can choose to keep the data.
