statusPattern not working as expected

[mbotalend]

Describe the bug

I'm not sure this is being a bug.
More likely a support request to setup a working statusPattern...

I've got this endpoint http://hyperhdr.local/json-rpc?xxxx
It returns me the following JSON body (truncated version):

{
    "command": "serverinfo",
    "info": {
        "videomodehdr": 0
    },
    "success": true,
    "tan": 0
}

I would like to use the videomodehdr property to get the state of my stateful switch:

• "videomodehdr": 0 => Switch OFF
• "videomodehdr": 1 => Switch ON

To do so I set up the statusPattern property as following:
"statusPattern": "/.*\"videomodehdr\": 1.*/gms"

But the switch status is aways being detected as OFF.

Expected behavior
The statusPattern/RegEx "statusPattern": "/.*\"videomodehdr\": 1.*/gms" to correctly set my switch status.

Version (output of npm list -g homebridge homebridge-http-switch)

• homebridge: 1.4.0
• homebridge-http-switch: 0.5.35

Hey @mbotalend, i had a similar issue and found out i need to "skip" whitespaces, beause the get striped out by the plugin. I guess the Phrasing of the Return-Body is the issue here.

However, if you enable debug mode and just copy the Logged status-Body, you'll see there are no whitespaces or returns. So, you'll need to test your regex with this "truncaded" response body.

In my Case, this is the response from the API (Postman):

                }
            ]
        }
    }
}

This is processed by the Plugin (copied from Terminal viewing the hb-log):

I guess, in your case, this whitespace here is the /.*"videomodehdr": ← Problem

By the way, it took me only 2 Hours to find this out 🤯 😁
