Example Flows

This section of the documentation includes example flows, you’re welcome to submit further flows either via a pull request on GitHub, via Slack or by contacting node-red@cb-net.co.uk.

Input Controller

This flow shows a simple Input Controller example for a Yamaha MusicCast AV Receiver (using Yamaha AVR Nodes as endpoint).

Note

There is no state supported by the InputController capability.

Flow code (copy and paste into Node-RED):

Tip

For this example to work you must install/ use the Yamaha AVR Node-RED nodes.

Playback Controller

This flow shows a simple Playback Controller example for a Kodi RPC endpoint (used as a Plex client).

Note

There is no state supported by the PlaybackController capability.

Flow code (copy and paste into Node-RED):

Tip

For this example to work you need to install the Kodi json-cec add-on, and setup fixed/ reserved IP addresses for your Kodi devices.

Motion Sensor

Note

Google Home does not currently support motion sensors, and as a result you cannot use these devices as triggers to perform other actions.

Use the flow below to send motion sensor updates to Amazon/ Alexa - useful if you want to be able to perform actions that may not be achievable locally via NBode-RED or MQTT (for example getting Alexa to speak or interact with other Alexa-connected smart home devices and services).

Function code needed to submit the state updates to the Node-RED Smart Home Control service, and in-turn Amazon:

// Motion State
if (msg.payload == "ON") {
    return { "payload" : { "state" : { "motion" : "DETECTED" } }, "acknowledge" : true };
}
else if (msg.payload == "OFF") {
    return { "payload" : { "state" : { "motion" : "NOT_DETECTED" } }, "acknowledge" : true };
}

Tip

In the majority of cases it will be more performant and more reliable to use your local Node-RED instance or MQTT server perform actions based upon motion sensor state changes.
