Hi @geekydrewbie,
I’m sure you have searched the forum for other Victron threads, and found
which states it might e possible to decrypt encrypted encoded BLE advertising broadcasts with Theengs Gateway, if the encryption key is known, OR use OpenMQTTGateway’s connection READ functionality to read GATT service/char from the devices if enabled, as stated in the last post.
Let us know how you get on.
