Hello everyone!

I have a SVEN MC-30 acoustic system and I need to power on it using IR Remote Pronto command.

The command from remote control was read using Xiaomi Home Assistant "remote.xiaomi_miio_learn_command", but there was a RAW output command - nMwmUwlk0mk4mEsms1ADIAdpjN5iAhoA/gD+Bx4CHgEeAR4BHgEeAQUwBY8GnwEPAH8CjwEKBb8CF5hAAA==

Could you, please, help me to convert this RAW command into Pronto HEX command, how is it possible to do?

Thank's a lot and best regards!

This looks like an IP command in base 64. If so, there will not be a simple translation to IR.

It does indeed look like base64. The Broadlink system uses (optionally) such an encoding. I tried to decode as Broadlink (using the snapshot version of IrScrutinizer), but that failed, so it is not Broadlink either.

You are right, it's base64 string - [Link: mantikor.github.io]

The result of decoding from BASE64 to HEX is:
9ccc26530964d26938984b26b350032007698cde62021a00fe00fe071e021e011e011e011e011e010530058f069f010f007f028f010a05bf0217984000 (use this site [Link: cryptii.com]

What should I do next?

Here is another converter, still not very useful data. On byte by byte basis there are lots of possibilities. Such as: binary option key, an 8-bit length prefix, 16-bit length prefix (little or big endien), or an ASCII character or …

What should I do next?

I chose another popular way to read IR command. What do we need:

1. Arduino compatible microcontroller (UNO R3 MEGA328P)
2. IRemote library [Link: arduinolibraries.info]
3. IrScrutinizer - an IR signal free software
4. Miniaturized IR receiver module:

        - Vishay TSOP31238 (1738) - for 38kHz known signal
        - Vishay TSMP58000 - for 20 - 60 kHz unknown signal

Received IR signal: Protocol=NEC Address=0x2 Command=0x57 Raw-Data=0xA857FD02 32 bits LSB first

How to convert to Pronto HEX: [Link: community.home-assistant.io]

Converted IR signal in Pronto HEX format:
0000 006C 0022 0000 015B 00AD 0016 0016 0016 0041 0016 0016 0016 0016 0016 0016 0016 0016 0016 0016 0016 0016 0016 0041 0016 0016 0016 0041 0016 0041 0016 0041 0016 0041 0016 0041 0016 0041 0016 0041 0016 0041 0016 0041 0016 0016 0016 0041 0016 0016 0016 0041 0016 0016 0016 0016 0016 0016 0016 0016 0016 0041 0016 0016 0016 0041 0016 0016 0016 0041 0016 05F7

It works. Thank's to everyone and best regards!
