I have not said it’s a switch. The name of the entity contains “switch”.

as far ask I can see in the original post

@Hellis81

I have earlier got the following working with some help.

switch.sonoff_1000000000:

so for HA it is a switch.

@Hellis81

But that doesn’t matter since it’s not the script that it reads the state of, it reads the state of the HDMI_state state.

It does matter as if you don’t clearly ask what you need it’s impossible to help.
As per this post.
