HowTo: Send JSON Command
Hi,

I like to send JSON Command as HTTP POST to my Hyperion Server.
I tested the command with a simple HTTP rest tool. The JSON in the body is
`{"command":"componentstate","componentstate":{"component":"LEDDEVICE","state":false}}`

That works for me, but I am not sure if implemented it correctly. Can someone have a look at it, if this is correct?
Thank you very much!

This is my Config for the Switch, but nothing happens. I also get no error.

```json
{
    "accessory": "HTTP-SWITCH",
    "name": "HTTP-SWITCH",
    "switchType": "toggle",
    "onUrl": {
        "url": "http://192.168.178.128:8090/json-rpc",
        "method": "POST",
        "body": {
            "command": "componentstate",
            "componentstate": {
                "component": "LEDDEVICE",
                "state": true
            }
        },
        "headers": {
            "Content-Type": "application/json"
        }
    },
    "offUrl": {
        "url": "http://192.168.178.128:8090/json-rpc",
        "method": "POST",
        "body": {
            "command": "componentstate",
            "componentstate": {
                "component": "LEDDEVICE",
                "state": false
            }
        },
        "headers": {
            "Content-Type": "application/json"
        }
    }
}
```
