node-red-contrib-philips-airjs

NodeRed node for Philips Air purifier in js.

What is AirJS ?

This is a node for Node-Red to view the status and send commands to Philips Air purifiers that use the COAP protocol (Encrypted). It is based on work by @biemond ( https://github.com/biemond/com.athom.philipsair.git ) and @betaboon ( https://github.com/betaboon/aioairctrl.git ).

There are other nodes in NodeRed for COAP based Philips Air purifiers but these use Python and bridge 'aioairctrl', so are not native JS implementations.

Configuration

In the IP/Host property of the node enter the IP address or Hostname of the air purifier.

Usage

The Node will observe and receive status message with all the current state information from the device. The output of these message is in JSON format with topic 'status', content will depend on your device type.

Commands

The input of the node accepts two type of commands.

Node control commands

'Observe' and 'Stop'. These will start and stop observing the device.

Device control commands

These are device specific commands.

Format: key value (example: pwr 0 switches the device off).

If succesful a message will be sent to the output with topic 'command' and payload {"status":"success"} (This means that the command has been received by the device, not that it is executed. An incompatible or not understood command can still have status of success). In case of failure the payload will be an error message.

Some commands (device specific):

Modes (Manual, Auto, Turbo, sleep)

mode M, mode AG, mode T, mode S

Fan speed

om 1, om 2

Power On/Off

pwr 1, pwr 0

Child lock On, Off

cl True, cl False

Buttons light: ON, Off

uil 1, uil 0

Other devices might have more and other commands. For some devices you first need to set the device to manual before adjusting fan speed.
