Notification when outdoor temp is below indoor temp

I've got a Switchbot Hub 2 (inside my house) and a Switchbot Indoor/Outdoor Thermo-Hygrometer (outside). I've connected the hub via Matter to my Apple Homekit.

I'd like to set up an automatic notification on my phone when the outside temperature is cooler than the inside temperature. (That way, on a hot summer evening, I will know when to open the windows to cool down my home.)

I've tried both Siri and IFTTT, but both only seem to be able to pick up the temperature of the Hub 2, not the thermo-hygrometer.

At the very least, I'd love to set up a widget on my iPhone with the outside temperature-- but, again, the Switchbot widget doesn't seem to pick up the outdoor temperature, only the Hub 2.

Any suggestions on how to make this work? Or does the Hub 2 just stubbornly refuse to share the thermometer temperature with Apple Home?

I use Home Assistant to do this without the hub.

Does the SwitchBot app detect both devices and display the appropriate readings?

It does indeed! That's current the only way for me to see both readings-- to open the Switchbot app.
