node-red-contrib-arduino-cloud

This module implements node-red nodes for interacting with Arduino IoT Cloud. Multi Arduino Account are allowed.

Installation

• Install node-red-contrib-arduino-cloud: npm install -g https://github.com/bcmi-labs/node-red-contrib-arduino-cloud.git

Configuration

1. Obtain from an Arduino Cloud account the Client ID and Client Secret
2. Select Arduino nodes from the pallete and drag to a flow
3. Double click
   • set a new connection
     • select 'Add new arduino-connection...' in the field 'Connection'
     • Click edit (Pencil button)
     • Insert a connection name, Client ID and Client Secret (collected at point 1)
     • Click Add
   • Select a thing
   • Select a Property
   • Set a name
4. Connect Arduino property input node to other nodes to consume data coming from a thing property.
5. Send a payload to the Arduino property output node to change the value of a thing property.

Nodes

property In

This node injects in the flow the changed value of a specific Arduino IoT Cloud property.

property Out

This node update a specific Arduino IoT Cloud property with the value received in input

historic

This node injects in the flow a set of values of an Arduino Cloud Property based on the node configuration.

Node parameter:

• Time Filter: defines time range for historical values

periodic

This node injects in the flow the value of an Arduino Cloud Property with a periodicity based on the node configuration.

Node parameter:

• Poll Every: defines polling time interval (seconds, minutes, hours, days, weeks)

inject

This node injects in the flow the value of an Arduino Cloud Property after receiving an input event.
