Calculate weather forecast through pressure?

[lons81 (Marcel)]

Hi

I want to build a weather station with ESPhome, mostley sensors are working fine.
But i also want a weather forecast without internet connection…
As pressure sensor i use a BME280.
How can i calculate the forecast with pressure?

Thanks,

I saw a post to do that the other day… Here it is:

Homeassistant 12h local weather forecast. ~94% accurate*

this homeassistant integration creates sensors to forecast local weather without the need for external services. Therefore it helps to get accurate weather data for the next 12h without the problem of changing services, API’s … Also only a barometer as a sensor is required (can also be pulled from online). But the forecast can be made more accurate with more sensors. . New Ecowitt integration! Plug’n’play use! new Ecowitt integration released! use GitHub - HAuser1234/HA_Ecowitt_Extended:…
