Blynk.io

Blynk.io provides an IoT dashboard for devices with virtual pins.

The pelikhan/devicescript-blynk package uses the HTTPS REST API to send data from devices.

Getting started

• Create a new DeviceScript project
• Add the library to your DeviceScript project:

npm install --save pelikhan/devicescript-blynk

Configuration

• Add device settings to your project
• Add the device authentication token to your settings

# .env.local
BLYNK_TOKEN=your-token

Uploading data

Use updateDatastream to update multiple virtual pins at once.

import { Temperature, Humidity } from "@devicescript/core"
import { delay, millis } from "@devicescript/core"
import { updateDatastream } from "devicescript-blynk"

// connect sensors
const temperature = new Temperature()
const humidity = new Humidity()

while (true) {
    // read sensor values
    const t = await temperature.reading.read()
    const h = await humidity.reading.read()

    // send blynk.io data
    await updateDatastream({
        v1: t,
        v2: h,
    })

    // take a break
    await delay(10000)
}
