If there's nothing to check in output, you can use function "self.dut.send_command(timeout=time)".
And 180 seconds is too long, what is waiting for?

Function "get_session_output" just return all output after timeout. Normally we will use default value, why enlarge time out value to 60 seconds?

Pep issue here, please modify it.

A bit tricky here, why double "statistics" here?
