Exception on CK-BL602-SWP1-01

[L4ky]

Hi, today i added 3 smart switch with energy monitoring (CK-BL602-SWP1-01) to my eWelink account. They've been updated to last firmware.

Reloaded the SonoffLAN component and it found 3 new entities.

They do not work since they raise an exception. Here is the exception, got from debug mode. No other relevant messages about SonoffLAN component.

I'm using SonoffLAN 3.5.1 in local mode.
