After a deeper study of the information available on the Internet, it seems that there is hope for the implementation of support for other sensors (as far as I understand, support for sensors with a method similar to ours is implemented in ESPHome). In addition to the already implemented work with LYWSDCGQ, I talk about:

• LYWSD02 (rectangular body, E-Ink) - dump received, work is done, supported since v0.4.0...

• HHCCJCY01 (MiFlora) - dump received, work is done, supported since v0.4.0...

• CGG1 (round body, E-Ink) - dump received, work is done, supported since v0.4.0...

• LYWSD03MMC ( square body, segment LCD) - dump received, need some help, start reading from this post.
  Collected tech.details summary.
  The decryption issue has been resolved, only the time for implementation is needed. Testing Released

ATTENTION! This topic discusses only questions regarding the operation of LYWSD03MMC sensors and methods for extracting encryption keys.

UPD. The dump didn’t help... Apparently, the advertisements are encrypted. But there is still hope!
