Homeassistant Samsung smart TV IR codes

Homeassistant IR codes for Samsung Smart TV

IR codes came from here

code was adapted from here

run:

python3 ir_codes.py ./samsung_tv_codes.csv

add the codes to you homeassistant/.storage/broadlink_...codes file.

in my case the file was named homeassistant/config/.storage/broadlink_remote_a04000000000_codes and looked like this:
