Python module to interface with Tuya WiFi smart devices

Project description

Python module to interface with Tuya WiFi smart devices

Description

This python module controls and monitors Tuya compatible WiFi Smart Devices (Plugs, Switches, Lights, Window Covers, etc.) using the local area network (LAN). This is a compatible replacement for the pytuya PyPi module.

Tuya devices are designed to communicate with the TuyaCloud but most also expose a local area network API, allowing us to directly control the devices without using the cloud. This python module provides a socket based way to poll status and issue commands to these devices.

NOTE: This module requires the devices to have already been activated by Smart Life App (or similar).

TinyTuya Setup

Install pip and python modules if you haven't already.

The PyPI module will attempt to install pycryptodome if you don't have it. The modules pycrypto, Crypto or pyaes could be used instead.

Tuya Device Preparation

Controlling and monitoring Tuya devices on your network requires the following:

Address - The network address (IPv4) of the device e.g. 10.0.1.100
Device ID - The unique identifier for the Tuya device
Version - The Tuya protocol version used (3.1 or 3.3)
Local_Key - The security key created to encrypt and decrypt communication. Devices running the latest protocol version 3.3 (e.g. Firmware 1.0.5 or above) will require a device Local_Key to read the status. Both 3.1 and 3.3 devices will require a device Local_Key to control the device.

Network Scanner

TinyTuya has a built in network scanner that can be used to find Tuya Devices on your local network. It will show Address, Device ID and Version for each device.

Setup Wizard

TinyTuya has a built in setup Wizard that uses the Tuya IoT Cloud Platform to generate a JSON list (devices.json) of all your registered devices. This includes the secret Local_Key as well as the Name of each device.

Follow the instructions below to get the Local_Key:

Download the 'Smart Life' App, available for iPhone or Android. Pair all of your Tuya devices (this is important as you cannot access a device that has not been paired).
Run the TinyTuya scan to get a list of Tuya devices on your network along with their device Address, Device ID and Version number (3.1 or 3.3):
NOTE: You will need to use one of the displayed Device IDs for step 4.
Set up a Tuya Account:
- Create a Tuya Developer account on iot.tuya.com and log in.
- Click on 'Cloud' icon -> Create a project (remember the Authorization Key: API ID and Secret for below)
- Click on 'Cloud' icon -> select your project -> Project Overview -> Linked Device -> Link devices by App Account (tab)
- Click 'Add App Account' and it will display a QR code. Scan the QR code with the Smart Life app on your Phone (see step 1 above) by going to the 'Me' tab in the Smart Life app and clicking on the QR code button [..] in the upper right hand corner of the app. When you scan the QR code, it will link all of the devices registered in your 'Smart Life' app into your Tuya IoT project.
- IMPORTANT Under 'API Management' -> 'API Products' and ensure the API groups have status 'Subscribed': Smart Home Devices Management, Authorization and Smart Home Family Management (see screenshot here) - Make sure you authorize your Project to use these 3 API groups:
  - Click each of the API boxes
  - Click 'Projects' tab
  - Click 'New Authorization' button
  - Select your Project from the dropdown and click OK (see screenshot here)
Run Setup Wizard:
- From your Linux/Mac/Win PC run the TinyTuya Setup Wizard to fetch the Local_Keys for all of your registered devices:
- The Wizard will prompt you for the API ID key, API Secret, API Region (us, eu, cn or in) from your Tuya IoT project noted above. It will also ask for a sample Device ID. Use one from step 2 above or found in the Device List on your Tuya IoT project.
- The Wizard will poll the Tuya IoT Cloud Platform and print a JSON list of all your registered devices with the 'name', 'id' and 'key' of your registered device(s). The 'key's in this list are the Devices' Local_Key you will use to access your device.
- In addition to displaying the list of devices, Wizard will create a local file devices.json. TinyTuya will use this file to provide additional details to scan results from tinytuya.scanDevices() or when running python -m tinytuya to scan your local network.
- The Wizard will ask if you want to poll all the devices. If you do, it will display the status of all devices on records and create a snapshot.json file with the results.

Notes:

If you ever reset or re-pair your smart devices, the Local_Key will be reset and you will need to repeat the steps above.
The TinyTuya Wizard was inspired by the TuyAPI CLI which is an alternative way to fetch the Local_Keys: npm i @tuyapi/cli -g and run tuya-cli wizard
For a helpful video walk-through of getting the Local_Keys you can also watch this great Tech With Eddie YouTube tutorial: https://youtu.be/oq0JL_wicKg.

Programming with TinyTuya

After importing tinytuya, you create a device handle for the device you want to read or control. Here is an example for a Tuya smart switch or plug:

TinyTuya Module Classes and Functions

TinyTuya Error Codes

Starting with v1.2.0 TinyTuya functions will return error details in the JSON data responses instead of raising exceptions. The format for this response:

The 'Err' number will be one of these:

900 (ERR_JSON) - Invalid JSON Response from Device
901 (ERR_CONNECT) - Network Error: Unable to Connect
902 (ERR_TIMEOUT) - Timeout Waiting for Device
903 (ERR_RANGE) - Specified Value Out of Range
904 (ERR_PAYLOAD) - Unexpected Payload from Device
905 (ERR_OFFLINE) - Network Error: Device Unreachable
906 (ERR_STATE) - Device in Unknown State
907 (ERR_FUNCTION) - Function Not Supported by Device

Example Usage

See the sample python script test.py for an OutletDevice example or look in the examples directory for other scripts.

Encryption notes

These devices uses AES encryption which is not available in the Python standard library. There are three options:

PyCryptodome (recommended)
PyCrypto
pyaes (note Python 2.x support requires https://github.com/ricmoo/pyaes/pull/13)

Scan Tool

The function tinytuya.scan() will listen to your local network (UDP 6666 and 6667) and identify Tuya devices broadcasting their Address, Device ID, Product ID and Version and will print that and their stats to stdout. This can help you get a list of compatible devices on your network. The tinytuya.deviceS
