Tuya-lib

Tuya-lib is an EXPERIMENTAL JVM library to control smart devices with Tuya firmware.

EXPERIMENTAL status means that this library is in incubating state - I'm lurking around, trying things and breaking them up. Library API and structure will be changed without additional notices. However, published maven artifacts will not be removed.

Features

WARNING: Only devices with firmware version 3.3 are supported for now.

Turn on a Bulb.
Turn off a Bulb.
Check if a Bulb is turned on.

Installation

Library is distributed via MavenCentral. Ensure that you have it enabled in build.gradle.kts:

repositories {
    // ...
    mavenCentral()
}

For snapshots

repositories {
    // ...
    maven("https://maven.pkg.jetbrains.space/dector/p/tuya-lib/mvn")
}

Add tuya-lib to your dependencies:

dependencies {
    // ...
    implementation("space.dector.tuyalib:library:0.1.0")
}

For snapshots

repositories {
    // ...
    implementation("space.dector.tuyalib:library:0.1.1-SNAPSHOT")
}

Sync your project with Gradle and you are done.

Usage

Controlling a bulb

You can check sample/ directory for minimalistic library usage example.

Simple android app example is available in another repository.

WARNING: Only bulb with firmware version 3.3 is supported for now.

WARNING: Your bulb need to be activated (instructions will be provided later).

val bulb = Bulb(
    // bulb IP in local network
    ip = "192.168.0.17",

    // device ID in Tuya system
    deviceId = "1ca7b0eb833a56fcf449",

    // local AES key for device
    localKey = "3e3de0d819e34753",
)

bulb.turnOn()

Use small delay between executing operations. Devices are slow and might skip your commands if you are sending them too fast.
