Arest switch for Arduino Ethernet

Hi Guys , hope some one can help.
Im sure its a config error but i just cant figure it out.
Im trying to setup a arest switch after my comand line switch’s but HA says it cant find the component switch ?

17-02-06 20:35:00 homeassistant.loader: Unable to find component -switch

I can send a Cmd to the switch with “http://192.168.1.133/digital/11/1” so the sketch is working.

my code below 

switch 0:
- platform: command_line
  switches:
    bar_audio:
      command_on: start c:\RelayBoard.exe 1 1 -simple
      command_off: start c:\RelayBoard.exe 1 0 -simple

    pool_audio:
      command_on: start c:\RelayBoard.exe 2 1 -simple
      command_off: start c:\RelayBoard.exe 2 0 -simple
      
    bedroom_audio:
      command_on: start c:\RelayBoard.exe 3 1 -simple
      command_off: start c:\RelayBoard.exe 3 0 -simple

    kitchen_audio:
      command_on: start c:\RelayBoard.exe 4 1 -simple
      command_off: start c:\RelayBoard.exe 4 0 -simple

    lounge_left:
      command_on: start c:\RelayBoard.exe 5 1 -simple
      command_off: start c:\RelayBoard.exe 5 0 -simple
      
    lounge_right:
      command_on: start c:\RelayBoard.exe 6 1 -simple
      command_off: start c:\RelayBoard.exe 6 0 -simple

    fish_tank:
      command_on: start c:\RelayBoard.exe 7 1 -simple
      command_off: start c:\RelayBoard.exe 7 0 -simple

    gatesw:
      command_on: start c:\RelayBoard.exe 8 1 -simple
      command_off: start c:\RelayBoard.exe 8 0 -simple
      
switch 1:
  - platform: arest
    resource: 192.168.1.133
    pins:
      11:
        name: pump 

I have never used arest, but just comparing your configuration with the documentation, I think you need an http:// in front of the IP address in the resource line.

Thanks for the reply , I have tired with and with out - for the moment im not even that worried about it functioning as im sure it will but just getting it to display. I have been playing around with the indention a lot as well in the hope that ill get it right but nothing yet.

Please try this syntax:

  command_on: "start c:\RelayBoard.exe 1 1 -simple"
  command_off: "start c:\RelayBoard.exe 1 0 -simple"

Thanks for the reply Mihai
Unfortunately it breaks the build with quotes .

This works for me.
