Tempest's lightning sensor has several features that highlight why the Tempest System is more than just hardware. The lightning sensor in your Tempest device can detect strikes up to 40 km away, and while it does a good job at detecting many strikes in this range, it is far from 100% efficient. The closer the strike, the more likely the sensor will detect it, but it can miss-report strikes at any distance.
It can also be susceptible to nearby electromagnetic interference and sometimes it's difficult for the algorithms onboard to tell if a strike is real or a "false positive".
Fortunately, the data reported by the individual sensor in your Tempest is supported by additional data and a sophisticated back-end process that significantly improves the reporting of lightning. This is accomplished by comparing data from your Tempest with other nearby Tempests along with several trusted, third-party lightning data sources. The result is the best lightning strike data available.
Strike Confirmation: Lightning strikes observed by a Tempest device are validated and processed normally.
False Strike Identification: When a strike from a particular Tempest device cannot be validated, it is flagged as a false positive (useful for quality control & analysis), and not reported to the user.
Missed Strike Correction: If the combined additional data sources confirm a lightning strike near a Tempest that was not detected by the device, the system will fill in the gap with the validated strike information.
Long-Term Improvement: The Tempest lightning detection system is already the most accurate system available to consumers and, over time, you will see even better and faster results. The rapidly expanding Tempest network is quickly making the system better and our Continuous Learning system will make adjustments to the lightning sensor configuration parameters in individual Tempest devices, when necessary. This customized fine-tuning of the sensor will optimize its performance at its particular location. Also, quality control alerts will proactively notify users in case there is some action they can take (such as relocating the Tempest away from sources of EMF) to further improve performance.
