Mercator AC fan controller model SSWF01G incorrectly reporting fan state

[Anhvariel]

What happened?

Mercator fan controller model SSWF01G regularly reports fan state as on when it is not. Both the "State" tab and "Exposes" tab show this incorrect fan_state value. Pressing the refresh button on the "Exposes" tab next to fan state will update the value and show it correctly. Also toggling the physical switch will update the value correctly. It seems as though the device regularly publishes an attribute report with fanmodesequence data which is being interpreted incorrectly as the fan being on. Se bolded log line below.

What did you expect to happen?

Fan state operating correctly.
