Python module to interface with Tuya WiFi smart devices

Description

This python module controls and reads state of Tuya compatible WiFi Smart Devices (Plugs, Switches, Lights, Window Covers, etc.) using the local area network (LAN) or the cloud (TuyaCloud API). 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 way to poll status and issue commands to these devices. Starting with v1.3.0, TinyTuya can also connect to the Tuya Cloud to poll status and issue commands to Tuya devices.

TinyTuya Diagram

    # Example Usage of TinyTuya
    import tinytuya

    d = tinytuya.OutletDevice('DEVICE_ID_HERE', 'IP_ADDRESS_HERE', 'LOCAL_KEY_HERE')
    d.set_version(3.3)
    data = d.status() 
    print('Device status: %r' % data)

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

TinyTuya Setup

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

# Install PIP
 sudo apt-get install python-crypto python-pip  # for some RPi or Linux systems

 # Install TinyTuya
 python -m pip install tinytuya

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 required to access the Tuya 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.

python -m tinytuya scan

Setup Wizard - Getting Local Keys

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, including secret Local_Key and Name of your devices. Follow the steps below:

  1. PAIR - Download the Smart Life App or Tuya Smart 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).

  2. SCAN - Run the TinyTuya scan to get a list of Tuya devices on your network. It will show device Address, Device ID and Version number (3.1 or 3.3):

    python -m tinytuya scan

    NOTE: You will need to use one of the displayed Device IDs for step 4.

  3. TUYA ACCOUNT - Set up a Tuya Account (see PDF Instructions):

    • Create a Tuya Developer account on iot.tuya.com and log in. NOTE: Tuya makes changes to their portal and this process frequently so details may vary. Please create an issue or pull request with screenshots if we need to update these instructions.
    • Click on "Cloud" icon -> "Create Cloud Project"
      1. Remember the "Data Center" you select. This will be used by TinyTuya Wizard (screenshot).
      2. Skip the configuration wizard but remember the Authorization Key: API ID and Secret for below (screenshot).
    • Click on "Cloud" icon -> Select your project -> Devices -> Link Tuya App Account (see screenshot)
    • Click Add App Account (screenshot) 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.
    • NO DEVICES? If no devices show up after scanning the QR code, you will need to select a different data center and edit your project (or create a new one) until you see your paired devices from the Smart Life App show up. (screenshot). The data center may not be the most logical. As an example, some in the UK have reported needing to select "Central Europe" instead of "Western Europe".
    • SERVICE API: Under "Service API" ensure these APIs are listed: IoT Core, Authorization and Smart Home Scene Linkage. To be sure, click subscribe again on every service. Very important: disable popup blockers otherwise subscribing won't work without providing any indication of a failure. Make sure you authorize your Project to use those APIs:
      • Click "Service API" tab
      • Click "Go to Authorize" button
      • Select the API Groups from the dropdown and click Subscribe (screenshot)

  4. WIZARD - Run Setup Wizard:

    • Tuya has changed their data center regions. Make sure you are using the latest version of TinyTuya (v1.2.10 or newer).
    • From your Linux/Mac/Win PC run the TinyTuya Setup Wizard to fetch the Local_Keys for all of your registered devices: 
      python -m tinytuya wizard   # use -nocolor for non-ANSI-color terminals e.g. Windows cmd
    • The Wizard will prompt you for the API ID key, API Secret, API Region (cn, us, us-e, eu, eu-w, or in) from your Tuya IoT project as set in Step 3 above.
      • To find those again, go to iot.tuya.com, choose your project and click Overview
        • API Key: Access ID/Client ID
        • API Secret: Access Secret/Client Secret
    • 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 that TinyTuya will use to provide additional details for scan results from tinytuya.deviceScan() or when running python -m tinytuya scan. The wizard also creates a local file tuya-raw.json that contains the entire payload from Tuya Cloud.
    • The Wizard will ask if you want to poll all the devices. If you do, it will display the status of all devices on record and create a snapshot.json file with these 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

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:

    import tinytuya

    d = tinytuya.OutletDevice('DEVICE_ID_HERE', 'IP_ADDRESS_HERE', 'LOCAL_KEY_HERE')
    d.set_version(3.3)
    data = d.status() 
    print('set_status() result %r' % data)

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:

{ "Error":"Invalid JSON Payload", "Err":"900", "Payload":"{Tuya Message}" }

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
  • 908 (ERR_DEVTYPE) - Device22 Detected: Retry Command
  • 909 (ERR_CLOUDKEY) - Missing Tuya Cloud Key and Secret
  • 910 (ERR_CLOUDRESP) - Invalid JSON Response from Cloud
  • 911 (ERR_CLOUDTOKEN) - Unable to Get Cloud Token
  • 912 (ERR_PARAMS) - Missing Function Parameters
  • 913 (ERR_CLOUD) - Error Response from Tuya Cloud

Example Usage

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

    import tinytuya

    """
    OUTLET Device
    """
    d = tinytuya.OutletDevice('DEVICE_ID_HERE', 'IP_ADDRESS_HERE', 'LOCAL_KEY_HERE')
    d.set_version(3.3)
    data = d.status()  

    # Show status and state of first controlled switch on device
    print('Dictionary %r' % data)
    print('State (bool, true is ON) %r' % data['dps']['1'])  

    # Toggle switch state
    switch_state = data['dps']['1']
    data = d.set_status(not switch_state)  # This requires a valid key
    if data:
        print('set_status() result %r' % data)

    # On a switch that has 4 controllable ports, turn the fourth OFF (1 is the first)
    data = d.set_status(False, 4)
    if data:
        print('set_status() result %r' % data)
        print('set_status() extra %r' % data[20:-8])

    """
    RGB Bulb Device
    """
    d = tinytuya.BulbDevice('DEVICE_ID_HERE', 'IP_ADDRESS_HERE', 'LOCAL_KEY_HERE')
    d.set_version(3.3)  # IMPORTANT to set this regardless of version
    data = d.status()

    # Show status of first controlled switch on device
    print('Dictionary %r' % data)

    # Set to RED Color - set_colour(r, g, b):
    d.set_colour(255,0,0)  

    # Brightness: Type A devices range = 25-255 and Type B = 10-1000
    d.set_brightness(1000)

    # Set to White - set_white(brightness, colourtemp):
    #    colourtemp: Type A devices range = 0-255 and Type B = 0-1000
    d.set_white(1000,10)

    # Set Bulb to Scene Mode
    d.set_mode('scene')

    # Scene Example: Set Color Rotation Scene
    d.set_value(25, '07464602000003e803e800000000464602007803e803e80000000046460200f003e803e800000000464602003d03e803e80000000046460200ae03e803e800000000464602011303e803e800000000')

Example Device Monitor

You can set up a persistent connection to a device and then monitor the state changes with a continual loop. This is helpful for troubleshooting and discovering DPS values.

import tinytuya

d = tinytuya.OutletDevice('DEVICEID', 'DEVICEIP', 'DEVICEKEY')
d.set_version(3.3)
d.set_socketPersistent(True)

print(" > Send Request for Status < ")
payload = d.generate_payload(tinytuya.DP_QUERY)
d.send(payload)

print(" > Begin Monitor Loop <")
while(True):
    # See if any data is available
    data = d.receive()
    print('Received Payload: %r' % data)

    # Send keyalive heartbeat
    print(" > Send Heartbeat Ping < ")
    payload = d.generate_payload(tinytuya.HEART_BEAT)
    d.send(payload)

    # NOTE If you are not seeing updates, you can force them - uncomment:
    # print(" > Send Request for Status < ")
    # payload = d.generate_payload(tinytuya.DP_QUERY)
    # d.send(payload)

    # NOTE Some smart plugs require an UPDATEDPS command to update power data
    # print(" > Send DPS Update Request < ")
    # payload = d.generate_payload(tinytuya.UPDATEDPS)
    # d.send(payload)

Tuya Cloud Access

You can poll and manage Tuya devices using the Cloud class and functions.

import tinytuya

# Connect to Tuya Cloud
# c = tinytuya.Cloud()  # uses tinytuya.json 
c = tinytuya.Cloud(
        apiRegion="us", 
        apiKey="xxxxxxxxxxxxxxxxxxxx", 
        apiSecret="xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx", 
        apiDeviceID="xxxxxxxxxxxxxxxxxxID")

# Display list of devices
devices = c.getdevices()
print("Device List: %r" % devices)

# Select a Device ID to Test
id = "xxxxxxxxxxxxxxxxxxID"

# Display Properties of Device
result = c.getproperties(id)
print("Properties of device:\n", result)

# Display Status of Device
result = c.getstatus(id)
print("Status of device:\n", result)

# Send Command - Turn on switch
commands = {
	'commands': [{
		'code': 'switch_1',
		'value': True
	}, {
		'code': 'countdown_1',
		'value': 0
	}]
}
print("Sending command...")
result = c.sendcommand(id,commands)
print("Results\n:", result)

Encryption notes

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

  1. PyCryptodome (recommended)
  2. PyCrypto
  3. pyaes (note Python 2.x support requires ricmoo/pyaes#13)

Command Line

    python -m tinytuya [command] [<max_retry>] [-nocolor] [-h]

      command = scan        Scan local network for Tuya devices.
      command = wizard      Launch Setup Wizard to get Tuya Local KEYs.
      max_retry             Maximum number of retries to find Tuya devices [Default=15]
      -nocolor              Disable color text output.
      -h                    Show usage.

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.deviceScan() function returns all found devices and their stats (via dictionary result).

You can run the scanner from the command line using this:

python -m tinytuya

By default, the scan functions will retry 15 times to find new devices. If you are not seeing all your devices, you can increase max_retries by passing an optional arguments (eg. 50 retries):

# command line
python -m tinytuya 50
# invoke verbose interactive scan
tinytuya.scan(50)

# return payload of devices
devices = tinytuya.deviceScan(false, 50)

Troubleshooting

  • Tuya devices only allow one TCP connection at a time. Make sure you close the TuyaSmart or SmartLife app before using TinyTuya to connect.
  • Some devices ship with older firmware that may not work with TinyTuya. If you're experiencing issues, please try updating the device's firmware in the official app.
  • The LOCAL KEY for Tuya devices will change every time a device is removed and re-added to the TuyaSmart app. If you're getting decrypt errors, try getting the key again as it might have changed.
  • Devices running protocol version 3.1 (e.g. below Firmware 1.0.5) do not 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.
  • Some devices with 22 character IDs will require additional setting to poll correctly - here is an example: 
      a = tinytuya.OutletDevice('here_is_my_key', '192.168.x.x', 'secret_key_here', 'device22')
  a.set_version(3.3)
  a.set_dpsUsed({"1": None})  # This needs to be a datapoint available on the device
  data =  a.status()
  print(data)
  • Windows 10 Users - TinyTuya wizard and scan interactive tools use ANSI color. This will work correctly in PowerShell but will show cryptic escape codes when run in Windows CMD. You can fix this by using the -nocolor option on tinytuya, or by changing the Windows CMD console registry to process ANSI escape codes by doing something like this: 
    reg add HKEY_CURRENT_USER\Console /v VirtualTerminalLevel /t REG_DWORD /d 0x00000001 /f

Tuya Data Points - DPS Table

The Tuya devices send back data points (DPS) also called device function points, in a json string. The DPS attributes define the state of the device. Each key in the DPS dictionary refers to key value pair, the key is the DP ID and its value is the dpValue. You can refer to the Tuya developer platform for definition of function points for the products.

The following table represents several of the standard Tuya DPS values and their properties. It represents data compiled from Tuya documentation and self-discovery. Devices may vary. Feedback or additional data would would be appreciated. Please submit a Issue or Pull Request if you have additional data that would be helpful for others.

DPS Read and Set Example:

# Read Value of DPS 25
data = d.status()  
print("Value of DPS 25 is ", data['dps']['25'])

# Set Value of DPS 25
d.set_value(25, '010e0d0000000000000003e803e8')

Important Note: Battery-powered Tuya sensors are usually designed to stay in sleep mode until a state change (eg.open or close alert). This means you will not be able to poll these devices except in the brief moment they awake, connect to the WiFi and send their state update payload the the Tuya Cloud. Keep in mind that if you manage to poll the device enough to keep it awake, you will likely quickly drain the battery.
