Hello Fabaff,

Please I am new to home assistant and having a problem I have been unable to fix for days as regards the restful switch.

I have added the switch to my configuration file, but it doesn't show up on the UI and this shows on the status "ERROR (MainThread) [homeassistant.components.switch.rest] Got non-ok response from resource: 404".

Please anyway to solve this?

Regards
