aioairctrl

Python library and CLI for controlling Philips air purifiers over the local network using the encrypted CoAP protocol.

Overview

Philips air purifiers (AC series) expose a CoAP endpoint on port 5683 of your local network. This library communicates with that endpoint using an AES-128/CBC encryption scheme reverse-engineered from the Philips app. No cloud connection or account is required.

Supported operations:

• Read the current device status (all sensor readings and settings)
• Observe live status updates as the device pushes them
• Send control commands to change settings

Home Assistant integration If you want to control your Philips air purifier from Home Assistant, see the companion integration: kongo09/philips_airpurifier_coap. It is built on top of this library.

Requirements

• Python 3.12 or newer
• The air purifier must be on the same local network (or otherwise reachable by IP)

Installation

pip install aioairctrl

Command-line usage

All commands require the -H/--host flag with the IP address of your purifier. Find it in your router's DHCP table or the Philips app.

Get current status

aioairctrl -H 192.168.1.100 status

Add --json to get machine-readable output:

aioairctrl -H 192.168.1.100 status --json

Watch for live updates

Stays connected and prints a new line each time the device reports a change (e.g. sensor readings, mode changes):

aioairctrl -H 192.168.1.100 status-observe
aioairctrl -H 192.168.1.100 status-observe --json

Press Ctrl+C to stop.

Set a value

String values:

aioairctrl -H 192.168.1.100 set mode=AG

Boolean values (true/false are handled automatically):

aioairctrl -H 192.168.1.100 set pwr=true
aioairctrl -H 192.168.1.100 set pwr=false

Integer values (use -I/--int):

aioairctrl -H 192.168.1.100 set -I om=2

Multiple values at once:

aioairctrl -H 192.168.1.100 set -I pwr=true om=2

Debug output

Add -D/--debug to any command to see the raw CoAP traffic:

aioairctrl -H 192.168.1.100 --debug status

Python API

import asyncio
from aioairctrl import CoAPClient

async def main():
    client = await CoAPClient.create(host="192.168.1.100")
    try:
        # Read status once
        status, max_age = await client.get_status()
        print(status)

        # Stream live updates
        async for status in client.observe_status():
            print(status)
            break  # stop after first update

        # Send a command
        await client.set_control_value("pwr", True)

        # Send multiple values at once
        await client.set_control_values({"om": 2, "rhset": 50})
    finally:
        await client.shutdown()

asyncio.run(main())
