Hi,
i was looking for a integration between ViewSonic projector and HA and i come across this code, can you tell me how to use/import it in HA?

I am very curious about including this too. I just got a viewsonic projector and would LOVE to make it work with my system.

No idea if this still works, my projector was from 2009 or so. I imagine it may have changed since then and I no longer have a projector at all.

Make a folder called custom_components inside your .homeassistant config folder (thu place where your YAML files are) and put it in there.

Thanks for your reply,
i think since then the structure of custom_component has changed a bit, it requires manifest file now:

i have tried this but didnt have much luck with it
