v1.2.11 - Updated Scan and Wizard Retry Logic

  • PyPi Version 1.2.11

# Explicit value set via command line
python3 -m tinytuya wizard 50   # Set retry to 50 
python3 -m tinytuya scan 50     

# Use automatic computed value
python3 -m tinytuya wizard      # Compute a default
python3 -m tinytuya scan        

# Example output
TinyTuya (Tuya device scanner) [1.2.11]

[Loaded devices.json - 32 devices]

  • Added Bulb type C and manual setting function set_bulb_type(type) (PR #54)
  • Wizard creates tuya-raw.json to record raw response from Tuya IoT Platform
  • Fixed device22 bug on retry - Now returns ERR_DEVTYPE error, status() includes auto-retry (#56)

v1.2.6 - Improved Error Handling

  • PyPi Version 1.2.6
  • Added wizard handling to capture and display Tuya API server error responses (PR #45)

v1.2.5 - Send and Receive Functions

  • PyPi Version 1.2.5
  • Added raw mode send() and receive() function to allow direct control of payload transfers. Useful to monitor constant state changes via threads or continuous loops. This example opens a Tuya device and watches for state changes (e.g. switch going on and off):
import tinytuya

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

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

while(True):
    # See if any data is available
    data = d.receive()
    print('Received Payload: %r' % data)

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

v1.2.4 - DPS Detection and Bug Fixes

  • PyPi Version 1.2.4
  • Added detect_available_dps() function
  • Fixed bug in json_error() function
  • Updated instruction for using Tuya iot.tuya.com to run Wizard
  • Added option to disable deviceScan() automatic device polling
  • Added better error handling processing Tuya messages (responses) Issue #39
  • Fixed display bug in Wizard device polling to show correct On/Off state

v1.2.3 - Dimmer and Brightness Functions

  • PyPi Version 1.2.3
  • Added set_dimmer() to OutletDevice class.
  • Added set_hsv() to BulbDevice class.
  • Updated set_brightness() in BulbDevice to handle white and colour modes. Issue #30
  • BulbDevice determines features of device and presents boolean variables has_colour, has_brightness and has_colourtemp to ignore requests that do not exist (returns error).

v1.2.2 - Bug Fix for Bulb Functions

  • PyPi Version 1.2.2
  • Fix bug in set_white_percentage(): added missing self. PR #32
  • Fixed set_white_percentage: colour temp was incorrectly computed for B type Bulbs. PR #33
  • Moved setup Wizard out of module init to standalone import to save import load.

Command line mode is still the same:

python3 -m tinytuya wizard

Import now requires additional import to run Wizard programmatically:

import tinytuya
import tinytuya.wizard

tinytuya.wizard.wizard()

v1.2.1 - Bug Fix for Command 0x12 UpdateDPS

  • PyPi Version 1.2.1
  • Fixed header for 0x12 Update DPS Command (see issue #8)

v1.2.0 - Error Handling and Bug Fixes

  • PyPi Version 1.2.0
  • Now decrypting all TuyaMessage responses (not just status)
  • Fixed set_colour(r, g, b) to work with python2
  • Fixed set_debug() to toggle on debug logging (with color)
  • Added handler for device22 to automatically detect and set_dpsUsed() with available DPS values.
  • Added set_socketTimeout(s) for adjustable connection timeout setting (defaults to 5s)
  • Added set_sendWait(s) for adjustable wait time after sending device commands
  • Improved and added additional error handling and retry logic
  • Instead of Exceptions, tinytuya responds with Error response codes (potential breaking change):

Example

import tinytuya

tinytuya.set_debug(toggle=False, color=True)

d = tinytuya.OutletDevice('<ID>','<IP>','<KEY>')
d.set_version(3.3)
d.status()

{u'Payload': None, u'Err': u'905', u'Error': u'Network Error: Device Unreachable'}

v1.1.4 - Update DPS (Command 18)

  • PyPi Version 1.1.4
  • Added updatedps() command 18 function to request device to update DPS values (Issue #8)
  • Added set_debug() function to activate debug logging “`python import tinytuya import time

tinytuya.set_debug(True)

d = tinytuya.OutletDevice(‘DEVICEID’, ‘IP’, ‘LOCALKEY’) d.set_version(3.3)

print(” > Fetch Status < “) data = d.status() time.sleep(5)

print(” > Request Update for DPS indexes 18, 19 and 20 < “) result = d.updatedps([18, 19, 20])

print(” > Fetch Status Again < “) data2 = d.status()

print(“Before %r” % data) print(“After %r” % data2)


## v1.1.3 - Automatic IP Lookup

* PyPi Version 1.1.3
* Updated device read retry logic for minimum response payload (28 characters) (Issue #17)
* Feature added to do automatic IP address lookup via network scan if _None_ or '0.0.0.0' is specified.  Example:
```python
    import tinytuya
    ID = "01234567890123456789"
    IP = None
    KEY = "0123456789012345"
    d = tinytuya.OutletDevice(ID,IP,KEY)
    d.status()

v1.1.2 - Bug Fix or 3.1 Devices

  • PyPi Version 1.1.2
  • Bug Fix for 3.1 Devices using CONTROL command - updated to hexdigest[8:][:16]
  • See Issue: #11

v1.1.1 - BulbDevice Class Update

  • PyPi Version 1.1.1
  • Updated BulbDevice Class to support two types of bulbs with different DPS mappings and functions: - Type A - Uses DPS index 1-5 and represents color with RGB+HSV - Type B - Uses DPS index 20-27 (no index 1)
  • Updated Colour Support - Index (DPS_INDEX_COLOUR) is assumed to be in the format: - (Type A) Index: 5 in hex format: rrggbb0hhhssvv - (Type B) Index: 24 in hex format: hhhhssssvvvv
  • New Functions to help abstract Bulb Type: - set_white_percentage(brightness=100, colourtemp=0): - set_brightness_percentage(brightness=100): - set_colourtemp_percentage(colourtemp=100): - set_mode(mode='white'): # white, colour, scene, music
  • Example Script https://github.com/jasonacox/tinytuya/blob/master/examples/bulb.py

v1.1.0 - Setup Wizard

  • PyPi Version 1.1.0
  • Added TinyTuya Setup Wizard to help users grab device LOCAL_KEY from the Tuya Platform.
  • Added formatted terminal color output (optionally disabled with -nocolor) for interactive Wizard and Scan functions.
python3 -m tinytuya wizard

v1.0.5 - Persistent Socket Connections

  • PyPi Version 1.0.5
  • Updated cipher json payload to mirror TuyAPI - hexdigest from [8:][:16] to [8:][:24]
  • Added optional persistent socket connection, NODELAY and configurable retry limit (@elfman03) #5 #6 #7 python set_socketPersistent(False/True) # False [default] or True set_socketNODELAY(False/True) # False or True [default] set_socketRetryLimit(integer) # retry count limit [default 5] * Add some “scenes” supported by color bulbs (@elfman03) python set_scene(scene): # 1=nature, 3=rave, 4=rainbow

v1.0.4 - Network Scanner

  • PyPi Version 1.0.4
  • Added scan() function to get a list of Tuya devices on your network along with their device IP, ID and VERSION number (3.1 or 3.3): python3 -m tinytuya

v1.0.3 - Device22 Fix

  • PyPi Version 1.0.3
  • Removed automatic device22 type selection. The assumption that 22 character ID meant it needed dev_type device22 was discovered to be incorrect and there are Tuya devices with 22 character ID’s that behave similar to default devices. Device22 type is now available via a dev_type specification on initialization: OutletDevice(dev_id, address, local_key=None, dev_type='default') CoverDevice(dev_id, address, local_key=None, dev_type='default') BulbDevice(dev_id, address, local_key=None, dev_type='default')
  • Added Tuya Command Types framework to definitions and payload dictionary per device type.
  • Bug fixes (1.0.2):
    • Update SET to CONTROL command
    • Fixed BulbDevice() __init__

v1.0.0 - Initial Release

  • PyPi Version 1.0.0
