Linux: https://github.com/Advantech-IIoT/Platform-SDK/tree/master/linux/bin

Install

Use npm command to install this package locally in the Node-RED modules directory

npm install node-red-contrib-atbrightness

or install it globally with the command

npm install node-red-contrib-atbrightness -g

Nodes included in the package

Brightness-data-get : Get information for devices.

Brightness-data-set : Set information for devices, e.g. Brightness Value.

---

Example

[Brightness-data-get]

Demo Flow: Brightness_Data_Get_Demo_Flow.json

It will output all of the information after deployment for once.

Output is a json format object:

• Min : Minimum Value of brightness
• Max : Maximum Value of brightness
• Value : Current Value of brightness
• Auto : Auto Brightness Status of brightness. [0: Manual, 1: Auto].

---

If the device does not support Auto Brightness, the output object:

{
    Min: 1,
    Max: 9,
    Value: 1,
    Auto: "Not Support"
}

You can write following example in the function node. It will output the same result.

msg.payload = {
    Min: 1,
    Max: 1,
    Value: 1,
    Auto: 1
};
return msg;

If you just want to get specific information, eg. Current Value of brightness: (number and boolean are valid value.)

msg.payload = {
    Value: 1
    // Or Value: true
};
return msg;

---

[Brightness-data-set]

Demo Flow: Brightness_Data_Set_Demo_Flow.json

This node can only receive a value for one time.

All you have to do is sending a format like msg.payload, type is number or boolean.

Set Current Brightness Value to specified value

If you send a number is not between Minimum and Maximum, you will get Not Support.

Set Auto Brightness

You can configure the payload True or False.
