node-red-contrib-ikea-home-smart

Node-RED node to interface with IKEA smart home products as tradfri lights or blinds without any external binaries thanks to node-tradfri.

• All operations (brightness, color temperature, color, etc.) supported by the gateway are available.
• Support for observation (i.e. reporting on changes to the light).

Usage

There is one node to configure each accessory type (besides the config node). After the configuration has been successful -- either by providing an existing identity and PSK or by generating new ones by providing the security code from the gateway -- simply select which accessory or group to target and check if the node should observe the device as well.

Notice: After configuring the gateway, you must apply the settings by deploying your flow. Only then can you create and configure the accessories.

Controlling the node

Nodes can be programmatically controlled by sending a message with msg.payload set to one of the following strings:

• "status" The node will output the current status of its target accessory.

Controlling the blinds

A blind's position can be controled by sending an object with the following property as msg.payload to the node.

• "position": number - The position in percent [0..100%].
• "trigger": number - A trigger event to stop a moving blind [0.0].

Controlling the lights

Lightbulbs can be controlled by sending an object with one or more of the following properties as msg.payload to the node.

All of them support the most basic properties, which are

• "dimmer": number - The brightness in percent [0..100%].
• "onOff": boolean - If the lightbulb is on (true) or off (false)
• "transitionTime": number - The duration of state changes in seconds. Default 0.5s, not supported for on/off.

White spectrum lightbulbs also support

• "colorTemperature": number - The color temperature in percent, where 0% equals cold white and 100% equals warm white.

RGB lightbulbs have the following properties:

• "color": string - The 6 digit hex number representing the lightbulb's color. Don't use any prefixes like "#", only the hex number itself!
• "hue": number - The color's hue [0..360°].
• "saturation": number - The color's saturation [0..100%].

Controlling the plugs (Untested)

Control a plug by sending an object with the following property as msg.payload to the node.

• "onOff": boolean - If the plug is on (true) or off (false).

Controlling the groups

A group contains several devices, usually a remote control and either lightbulbs, plugs or blinds. To control the group send the following properties as msg.payload to the node:

For a group of lights

• "dimmer": number - The brightness in percent [0..100%].
• "onOff": boolean - If the lightbulb is on (true) or off (false)
• "transitionTime": number - The duration of state changes in seconds. Default 0.5s, not supported for on/off.

For a group of blinds

• "position": number - The position in percent [0..100%].

For a group of plugs

• "onOff": boolean - If the plug is on (true) or off (false)

Additionally, this property is also supported:

• "sceneId": number - Set this to the instanceId of a scene (or "mood" as IKEA calls them), to activate it.

Status node output

If a status request is send or a device's state is updated, the node will respond with a msg.payload containing its current properties.
