Philips 2000i Series AC2889/40

Quick verdict

Discontinued by Philips, so treat it as an existing-owner or old-stock pick rather than something to buy new. It is 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. If you want the same local CoAP route on a model Philips still sells, the 1000i (AC1715) and 800i (AC0850) series are covered by the same integration.

Compatibility snapshot

Why it stands out

• Local push integration via CoAP, no Philips cloud account needed
• Exposes numeric PM2.5, allergen index and filter wear as HA sensors
• Strong HEPA + active carbon filtration

Reasons to hesitate

• CoAP local control can be unstable and some firmware disables it
• Community/HACS integration only, no official HA support
• Discontinued: Philips' own US product page for the AC2889/40 now carries a Discontinued ribbon, so new units are remaining stock only

Best for

• Existing owners, and privacy-focused buyers who find remaining stock and want local CoAP control with detailed air-quality sensors

Avoid if

• you are buying new today - this model is discontinued; look at the Philips 1000i (AC1715) or 800i (AC0850), which the same CoAP integration supports

Privacy and local-control notes

The CoAP custom component connects directly to the purifier on the LAN and receives pushed state, bypassing Philips' cloud entirely.

Buying reality check

Price notes: Was around $300 while it was current. Now discontinued, so pricing depends on whatever third-party stock is left.
