 Ecowitt rolled out a new firmware update in 2025 that dynamically calculates SLP (sea level pressure) factoring in elevation, station pressure,temperature and humidity. This new update is a radical departure from the previous algorithm, where sea level pressures were somewhat crudely approximated using a simple fixed offset.
