Information on retro engineering Silvercrest (Lidl) Smart Home Gateway

[Julien-soft]

Hello,
Thank you for your very detailed work.
I can confirm that this technique works on the "smarthome silvercrest 2021". 👍
I have some questions about the identification of the addresses where the keys are stored and the identification of the encryption algorithm (AES).
How did you identify the physical addresses?
how did you figure out that the data was encrypted with AES?
