I have a wifi based PM2.5 device from 352 air company, and i found its homebridge plug-in from GitHub - mckelvin/homebridge-352air: Homebridge plugin for 352Air PM2.5 Sensor (352 PM2.5空气检测仪 http://www.352air.com/jianceyi1/index.html ), which is not supported HA. So I am wondering anyone can help to make it work in HA or any advise to go through with this. As far as i know, you can get most of code information from here homebridge-352air/index.js at 292bf2046354b734e5dfe8b91dbd1c7e1cf7cfab · mckelvin/homebridge-352air · GitHub

Look like a Node Red flow is a good way to integrate this device to HA, and I can not find any UDP server integration in HA to listen udp message. Anyone know how to do this?
