Weather forecast using ambient temperature, humidity, barometric pressure and other datas

In my effort to make everything works offline, one of the component that I got stuck is weather forecast. At the moment, I am using Darksky. Like all other weather components, it relies on Internet and the availability of the third party service. It will not work if Internet is down or the service provider decided to end its service.

I wonder is it possible to do weather forecast if I can gather organic data such as outdoor temperature, humidity and barometric pressure using sensor such as Bosch BME280?

In days gone by, the house I grew up in and many others had a thermometer, hygrometer and barometer, for home weather prediction. You could replicate that with electronic weather sensors today.

There is a nice writeup on the history and how-to of barometric weather prediction here:

I suspect though, that much more accurate prediction is possible with the addition of weather radar and a network of weather stations, which would be less viable to do in isolation.

I have an Acurite 5 in 1 weather station that I send data to Weather Underground and then reuse that with the WU component by specifying my weather station code.

But you could instead get a box that intercepts the data and then reroutes it; to multiple services as well as locally in it’s own weather page interface. It’s very cool, and based on flashing a custom ROM to a select list of cheap small wifi routers or you can buy one as a hardware unit with the firmware installed.

It’s a really cool little project:

Acurite sounds like a good idea. But how do you send the data to HA?

You can plug the display into your PC and run a program, but I have mine connected wireless via their smartHUB.

That sends the data to MyAcuRite.com which forwards it to WU (Weather Underground).

Then I load the WU component and specify my weather station ID as the source.

Explained this in the previous post. You could also hook up meteobridge and grab the data directly.

This setup includes everything I have; currently at the same price I paid for just the 5in1 sensor when I bought it.

Hey @masterkenobi - in case you’re interested, Woot! (a part of Amazon) has this setup for $20 off the price above but they usually sell out in a day or two.

I have bought a BME280 sensor, is there a way to do it on HA?

I bought a weather station a week ago. The barometer stay the same 99% even there is thunderstorm outside. Its 29.74in -29.76in. Does it matter where i put the device ? It seems useless to me.

Did anyone get any were with this ?
