Description of problem:

1. Command learning works fine, that's all.
2. While trying send command with json { "entity_id": "remote.miir","command":"ac28"} , it failed.
   with or without "raw:" at the beginning of the learned command.
   If the command is beginning with "raw" or ending with ":38400" , it will fail with exception: {'code': -5008, 'message': 'magic error'}.
   If the command doesn't have either of beginning "raw:" and endding ":38400", the remote controller will die! The light will go off and network connection also lost.

[syssi]

Please try to update the learned commands. I assume they are improper.

[xcray]

after upgraded to 0.72.1, retried as @syssi advised, and succeed. I don't know if it's because of the versions's difference.

re-enable ir remote in configuration.yaml, restart HA, learn the commands again and edit configuration again (add blank after "- raw:", which is not correct), and restart HA again. then failed again while trying send command:

remove the blank after "raw:" and restart HA, it succeed!
Thank you @syssi , so the commands I put into the configuration file last time (on 0.71.0) maybe have some problems.
