Heat pump aux heat indicator?

Is there any way to tell when the stat is calling for stage 2 or auxiliary heat? What about the differential for when it calls aux(usually it’s 2deg) ? It seems like I’m getting really warm air, which usually means aux heat is on, so curious if there’s a way to tell (my old stat had an indicator).
Thanks!

I would also like to know this. My aux heat is getting kicked off well within a schedule window. It stops running heat all together, the temp drops far enough for the aux heat to kick off instead of just having the compressor continue to run.

No replies to this?
I would like an Indicator and more control over Aux Heat.

I would also like this function. No idea when the system is using the secondary heating in a heat pump system.
