Xiaomi vacuum acces token format

Dear Collegues

I have a Xiaomi robo vacuum. I got access key using pocket sender.

token: “21 32 01 20 00 00 00 00 05 C5 EA 1B 00 10 C3 2D 48 57 46 77 69 4E 47 79 55 37 4F 49 61 3E 6B 40”
(I changed the numbers, the format is what I found)

It is not the correct format of token by log. What is the correct format?

It sounds like you need to do step 13 under the iOS section here https://www.home-assistant.io/components/vacuum.xiaomi_miio/

Open Terminal and execute this command: echo '0: <YOUR HEXADECIMAL STRING>' | xxd -r -p | openssl enc -d -aes-128-ecb -nopad -nosalt -K 00000000000000000000000000000000

Dear m841

Can you help me how to use this command? It gives me lots of non printable characters.
