I found a similar issue with S2, theory at the time was it was an upstream problem, I haven't tried since then. Can you get some log output?

I use very verbose, logger

debug [05:42:19][D][internal_temperature:052]: Ignoring invalid temperature (success=0, value=nan)

May I ask how to debug in detail

Is there an issue with the upstream version of IDF,

I played with this on my C6 and found the ESP-IDF function call is returning the no data sentinel, so ESPHome correctly discards it.

The bug will have to be handled on the ESP-IDF side from what I can tell.
