It would be useful, if you just could swipe down to reload the showing entities, like most tableview-style apps.
And by the way the app doesn’t reload temperatures when you open it again.
This is somewhat unneeded since we update the states in real time thanks to the Home Assistant EventStream/Server Sent Events API, so what you see is always the latest states.
Okay if this works it is really unneeded.
