I'm able to read that data via script on my Shelly Plus Plug S but that data are encrypted. 🔐

The encryption is done using a AES-CTR operation

Shelly scripting environment is very limited and I'm unsuccessful with decrypting that data yet.

Thank you

any ideas how to re-implement AES-CTR in limited JS subset compatible in Shelly scripting environment) ?

[t0urista]

Same problem for the encrypted BThome protocole implemented by the Shelly BLU devices, once encryption enabled, scripts cannot get data anymore. we need a way to decrypt AES encrypted data in shelly scripting language

It seems possible to do that, ist't wifi using similar? Ist there already a support by shelly für using encryption in scripts?
