web-toothbrush

Yet another IoT JS library nobody asked for

Overview

This library is unofficial and I'm in no way associated with the manufacturers of these devices. Use at your own risk.

This is a simple JavaScript library that uses the Web Bluetooth API to connect a smart electric toothbrush that supports bluetooth.

Depending on the model allows you to read the current status during a session, modify settings or read data from previous sessions.

Usage

1. Install using NPM.

npm i web-toothbrush

2. Import the Toothbrush class.

import { Toothbrush } from 'web-toothbrush'

3. Connect to your device and receive a BluetoothRemoteGATTServer object.

// This displays a dialog to the user
const device = await navigator.bluetooth.requestDevice({
  acceptAllDevices: true,
  optionalServices: Toothbrush.services // contains list of GATT services used
})

// Connect to the GATT server
const server = await device.gatt.connect()

4. Make an instance of Toothbrush.

const toothbrush = new Toothbrush(server)

5. Query some properties.

const batteryLife = toothbrush.getProperty('batteryLevel')
if (!await batteryLife.isAvailable()) {
  // tough luck, we can't query that property
}
console.log(await batteryLife.readValue())

Simple version

In most cases, you can just use Toothbrush.connect() if you don't want to worry about all the bluetooth connection trouble:

import { Toothbrush } from 'web-toothbrush'

[...]

const toothbrush = await Toothbrush.connect()
const batteryLife = toothbrush.getProperty('batteryLevel')
[...]

Supported properties

The following properties can be accessed via the bluetooth API. Availability depends on the model of your device.

General information

All of these properties are read-only.

• handleId - the unique ID of the device
• deviceType - the type of the device
• userAccountId - ID of user account
• batteryLevel - current battery percent
• data - information about previous saved sessions

Current session

These properties are read only, but can be subscribed to and reflect the status of the current session in progress.

• brushingTime - how long the toothbrush has been on
• buttonState - whether a button is pressed and which
• mode - current brushing mode
• pressureSensor - whether a pressure sensor is currently triggered
• quadrantProperty - the quadrant currently in progress
• smiley - current "smiley" state
• state - current toothbrush state

Configuration

These properties can be read or modified to affect the toothbrush behavior.

• brushingModes - modes that can be triggered and used
• brushingTimer - how the user is notified about the timer state
• color - color of the LEDs
• command - used internally by other properties to send commands
• flightMode - used to enable or disable flight mode
• pressure - how the user if notified about the pressure sensor
• quadrantTimes - how much time is spent per quadrant
• rtc - current time
• timezone - current time zone / locale
• tongueTime - how much time is spent in tongue cleaning mode

Supported devices

The following toothbrushes are currently supported by this library:

• Oral-B Genius 9000
• Oral-B Genius 8000
• Oral-B Teen
• Oral-B SmartSeries 6500
• Oral-B Smart 5 5000N
