A timestamp representing the estimated time when the target temperature will be reached

Hello :slight_smile:

It would be great to be able to have a timestamp representing the estimated time when the target temperature for a sensor will be reached.

Use case example:
Given two temperature sensors (outdoor / indoor)
When estimated time, for the indoor sensor to reach target temperature (outdoor sensor), is less than X minutes, send a notification (open/close windows).

PS: If someone is willing to help me, I could try to implement this but Iā€™m a newbie.
