Sorry, 1st PR... :)
Better this way ?

I don't think you need this. switch.toggle works just fine, right?

[ikucuze]

I'll try to remove it to check that, but I think I tryed.
I think I couldn't have it displayed on GUI then, or that the GUI does not offer the "toggle" button. I might have miss something ?

[ikucuze]

As expected:
File "/mnt/d/git/home-assistant/homeassistant/helpers/entity.py", line 388, in turn_on
raise NotImplementedError()

The switch exposed on the GUI uses on/off function. It would probably possible to call toggle directly, but in order to have a more user friendly interface, I think it is better to keep the "turn_on" function.
