I’ll leave this thread open for others to vote on as well. We’ve had feedback that there’s too much information displayed on the weather tiles already, so we’ve been hesitant to add more to the tile.
A key part of how we prioritize what we work on is community feedback, so if enough people share the interest in adding pressure to the weather tile, that helps get it bumped up the list!
That being said, there’s a fairly straight forward way to accomplish this with Hero Attribute tiles as shown above.
A popular approach to weather is to use Media Tiles to integrate weather from your favorite sources. You can find more information in the Weather Tiles help article or by searching this community for ‘weather’ - for example, the Weather Sources thread is popular
It would be cool if the weather tile where like the hero tile that we could select what info we want to display. I agree on smaller tablets the tile gets busy if you try to match it to the other tiles.
