Multiple curl calls in a command_line

Configuration
1

I have the following command line…

- platform: command_line
  switches:
    garagedooricon:
      command_off: 'curl "http://192.168.0.110:8090/syslog?type=INFO&message=Garage_Closed&silent=true"'
      command_on: 'curl "http://192.168.0.110:8090/syslog?type=INFO&message=Garage_Open&silent=true"'

I wan to add more http curl calls to this like the following…

- platform: command_line
  switches:
    garagedooricon:
      command_off: 'curl "http://192.168.0.110:8090/syslog?type=INFO&message=Garage_Closed&silent=true"'
      command_off: 'curl "http://192.168.0.50:8090/syslog?type=INFO&message=Garage_Closed&silent=true"'
      command_on: 'curl "http://192.168.0.110:8090/syslog?type=INFO&message=Garage_Open&silent=true"' 
      command_on: 'curl "http://192.168.0.50:8090/syslog?type=INFO&message=Garage_Open&silent=true"'

But it will not call both on a “on” command, it only calls one item. How do I get it to call both?

Not directly to your question. That said, I have found good results by using the command_line sensor with bash scripts. Makes it a bit easier to debug, without having to start and stop HA as you revise. Example below sends parameter to bash script and returns results in a JSON string to HA. I have crammed several script commands on to a single line of a command_line command: argument, however, it gets messy quickly. Good hunting!

# network bandwidth

Like this:

command_off: 'curl "http://192.168.0.110:8090/syslog?type=INFO&message=Garage_Closed&silent=true" && curl "http://192.168.0.50:8090/syslog?type=INFO&message=Garage_Closed&silent=true"'

I found this thread having the same issue. Solved it like this as I supect HA only forwards whatever you write as command to the underlying linux OS and there you can run several commands in sequence by separating them with &&. So Commad1 && Command2 && Command3. From my testing it appears 2 will not be run before 1 is done. But not sure. Anyway. I can run several curl commands like this, with no issue

*I know this is an old thread, but maybe someone else can find it in search of answers :grinning_face_with_smiling_eyes:
