This is a simple Prometheus metrics collection bridge for Philips' Wi-Fi connected air purifiers. It is based upon py-air-control, and Flask
Only CoAP purifiers are supported, and it is only tested with the AC2889/10. I made this as a quick hack for my own use. Status requests are sent to the purifier in response to Prometheus scrapes
Start it with the IP or hostname of your purifier and any required parameters, e.g.
$ airprom --listen "::0" 192.168.1.33
