Barometric pressure monitoring and alerting, and heat index calculation

📐 Rule Machine®
1

Has anyone created any Rules which monitor and alert on barometric pressure or changes over time? For example, a fast drop in barometric pressure can indicate a strong storm approaching, or a tornado (although I've been in a tornado, and you'll notice that pressure drop with your ears when it happens).

Since I now have an Aqara temp/hum/pressure sensor outside, I thought that this might be kind of a cool thing to monitor and alert on.

Also, looking to create a virtual tile that lists Heat Index (Heat index - Wikipedia). Would I have to create an app for that?

APIXU doesn't offer an index per se. They offer "feels_like" in both F and C

Perhaps that's usable to you?

I doubt the "speed" of Free Website Data, since their data is coming in from reporting stations that may be distant from you or report rarely.

Is there any ability within HE to take values from a couple of sensors, do some math on them, and then have it write the result to a virtual device?
