 """
 Support for The Shelly Wifi switch.

 Save this file inside ".homeassistant/custom_components/switch" (create the folders if not present) and restart HASS.

 usage example:

 switch:
  - platform: shelly
    switches:
      shelly_switch:
        path: /relay/0 (optional, defaults to /relay/0)
        host: 10.0.0.219
        username: admin
        password: admin
        
 Path is optional and defaults to '/relay/0'. If you have the 2-relay Shelly for the second one use /relay/1.
 Username & Password are optional. Use only if you have enabled authentication from the shelly web interface.
