can't access entity (i dont know how to call it

[lavish bough]

hi. i added the library from the link
https://github.com/thecode/ha-rpi_gpio
added this entry to configuratiuon.yamp

  - platform: rpi_gpio
    switches:
      - port: 11
        name: "Chlodzenie raspberry"```
but when adding a tile on my dashboard there isn't the `chlodzenie raspberry` option
