I am trying to install my Sonoff TH 16 with RCWL 0516 motion detection but am running into problems:

I can not call it “binary_sensor” because this is being called further up already.
how can I fix my issue?

You can’t just invent component names. binary_sensor let’s the code know it should use the binary sensor component. Adding 2 will cause it not to match.

Delete the binary_sensor2 line, cut everything which was below it & paste it immediately under the original binary_sensor line.

That should fix your error.
