Barf, have you seen this format of learned signals before? (I added line breaks)

Power:

I got them from the following site:
https://community.home-assistant.io/t/l ... zon/144607

These are the same signals as those discussed here:

{38.5k,497,msb}<1,-1|1,-3>(9,-9,A:16,1,-9,B:20,1,-52.0m)
Power 1 {A=$0C54,B=$5024F} {A=0b0000110001010100,B=0b01010000001001001111}
CH+ 23 {A=$0C54,B=$5C5F1} {A=0b0000110001010100,B=0b01011100010111110001}
CH- 23 {A=$0C54,B=$52571} {A=0b0000110001010100,B=0b01010010010101110001}

Rob,
These signals are written in Base64 encoding.
https://cryptii.com/pipes/base64-to-hex
Paste into the left hand box and the hex is displayed on the right box.
Power then decodes to After the first 4 bytes, 8a 96 0d 14 is the 9,-9 leading and the first signal 0. Each pair of bytes encodes either 1,-1 (e.g. 0e 12) or 1,-3 (e.g. 0e 33). I'm not sure about the initial 4 bytes or the trailing bytes. The midframe burst in this example is 0C 96

Thanks Dave

Dave has already explained the encoding. Actually, IrScrutinzer can already export in Home assistant/base64 format (see this). So it remains to implement the import direction Stay tuned...
