Hi thanks for the efforts putting this together.

On the first pair, i save the key to the config file and keys work successfully. On power off and immediate power on, the same key still works.

However after a couple of days, it no longer works resulting in the below error messages

Using config file: /data/samtvcli/samtvcli.yaml"
time="2020-07-14T21:31:09Z" level=error msg="Could not parse message: cannot decrypt response: invalid padding"
time="2020-07-14T21:31:13Z" level=error msg="Cannot send key 'send': no reply from TV"

Then it works again when i repair it.

Is this the expected experience?
