Serial number mismatch.

[DrWhoop-73]

Hi,

First time posting a message on github, so forgive me if the information is incomplete.

I'm trying to get this Add-on working with my solarman wifi dongle, but I must be doing something wrong. When I start the Add-on I see this error message in the log:

Serial number mismatch. Expected 'my_serial_number', got ÿÿ� .

The mismatch seems to occur on the Serial number of the inverter. Then I noticed this discussion: #174 where there is mention that I don't need the inverter number, but instead just need to enter ''. Unfortunately this results in the same error:

Serial number mismatch. Expected “”, got ÿÿ�

Included: a screenshot of my Solar wifi dongle. Please let me know if more information is needed.

Cheers!
