That probably means the features mentioned on the zzh product page is related to the TI chip itself but probably not activated on the zzh! USB Stick firmware. I will continue to investigate…
While waiting to find the perfect solution, I dedicated an ESP32 board with ESPHome integration to manage Xiaomi Mi Thermometer 2. It works fine, but I have one more gateway hardware to “maintain” (but this is another topic )
Anyway, many thanks for your answer and the video link
Unfortunately not… after looking more deeper it seems the feature is on the TI microcontroller, but not implemented in zzh! stick firmware then no way to easily use it.
In my case, I’m still using ESP32 board as a Bluetooth gateway integrated with ESPHome.
It works like a charm in my 80sqm apartment, I’m able to manage my “Xiaomi Mi Thermometer” Bluetooth devices as well as as doing presence detection with device like smartphones and tablets.
