Device not being discovered

[Gsy-mich]

Had a bit of a battle getting the integration installed and running, kept running into 'An unknown error occurred' message after clicking 'submit' when configuring the integration. I've now got the integration loaded, but I am now getting a 'Failed to setup: Check the logs' error. The error log is

Error setting up entry T-Smart Thermostat for t_smart

OSError: [Errno 98] Address in use

Note: I have had this integration installed and working fine previously, it randomly stopped working and I had to uninstall and reinstall recently. The thermostat is operational and responding as expected in the TSmart app
