Quick verdict
A 333 m3/h purifier that exposes full local push control of fan speed, mode and PM2.5 sensors over the encrypted CoAP protocol with no cloud account required. The CoAP custom component connects directly to the purifier on the LAN and receives pushed state, bypassing Philips' cloud entirely. Just note: CoAP local control can be unstable and some firmware disables it.
Standout: A 333 m3/h purifier that exposes full local push control of fan speed, mode and PM2.5 sensors over the encrypted CoAP protocol with no cloud account required.
