'Hide Light Switch' on iFan03 Not Working?
Hi, and thanks for this great plugin!

I have it running my Sonoff iFan03. I set it up on HOOBS with the default configuration (i.e. exposing the light switch), but then changed the configuration page to 'Hide Light Switch' under 'Fan Devices'. However, the light switch still showed in Apple Home. Thinking this might be a HomeKit artefact, I deleted the entire bridge from Home, checked the fan and light had gone from Home, and then re-added the bridge. However, once I'd 'split' the combined fan device in Home, it still shows as the Fan and Light, i.e. I still can't hide the light switch. I'm trying to hide the light switch as I've installed Hue bulbs so want them permanently switched on so they're controllable.

Looking at the HOOBS logs, the plugin seems to be throwing an error which I'd guess is linked to this (4th line):
