Dechiper JSON message from boiler

1

Hi,

Not sure where to post this, so I’ll try here first.

My boiler has the ability to send a message when it encounters an error. Its a pellet boiler and needs cleaning and refuelling regularally.

I get a message such as the one below, which I currently receive as a trigger into a Node-red flow,

I want to extract the msg field, and send a different push message or action depending upon the error.

Any suggestions how I would start?

Web socket - Windhager Error: POST /DynIP/OnAlarm HTTP/1.1
Content-Type: application/json; charset=UTF-8
Content-Length: 87
Connection: Keep-Alive
Accept-Encoding: gzip, deflate
Accept-Language: en,*
User-Agent: Mozilla/5.0
Host: 192.168.1.68:5432

{
“MAC”: “00-23-43-00-xx-xx”,
“id”: “(60) BioWIN 2”,
“msg”: “FMP 09 OK”
}

Thanks
Paul

Where do you get that.
Is it an object or string?

Sorry, I never got around to this. I receive it as a string through a tcp in node.
I want to send a different notification depending on the content of the msg field.
Any suggestions?
