def hex2bytes(data: str)

Parse hexstring to bytes.

Module tuyaface.tuyaclient {#tuyaface.tuyaclient}

Helper to maintain a connection to and serialize access to a Tuya device.

Classes

Class TuyaClient {#tuyaface.tuyaclient.TuyaClient}

class TuyaClient(device: dict, on_status: <built-in function callable> = None, on_connection: <built-in function callable> = None)

Helper class to maintain a connection to and serialize access to a Tuya device.

Initialize the Tuya client.

Ancestors (in MRO)

• threading.Thread

Methods

Method run {#tuyaface.tuyaclient.TuyaClient.run}

def run(self)

Tuya client main loop.

Method set_state {#tuyaface.tuyaclient.TuyaClient.set_state}

def set_state(self, value, idx: int = 1)

Set state.

Method status {#tuyaface.tuyaclient.TuyaClient.status}

def status(self)

Request status.

Method stop_client {#tuyaface.tuyaclient.TuyaClient.stop_client}

def stop_client(self)

Close the connection and stop the worker thread.

example

from tuyaface.tuyaclient import TuyaClient

def on_status(data: dict):
    print(data)

def on_connection(value: bool):
    print(value)

device = {
    'protocol': '3.3', # 3.1 | 3.3
    'deviceid': '34280100600194d17c96',
    'localkey': 'e7e9339aa82abe61',
    'ip': '192.168.1.101',            
}

client = TuyaClient(device, on_status, on_connection)
client.start()

data = client.status()
client.set_state(!data['dps']['1'], 1) #toggle
client.stop_client()

Data structure

Device dict

device = {
    'protocol': '3.3', # 3.1 | 3.3
    'deviceid': '34280100600194d17c96',
    'localkey': 'e7e9339aa82abe61',
    'ip': '192.168.1.101',
    'pref_status_cmd': 10 #optional, default 10
}

TuyaFace will automatically add tuyaface dict to the device with data to support implementations without the TuyaClient class.

tuyaface = {
    "sequence_nr": 0, # Request counter
    "connection": None, # Holds the connection 
    "availability": False, # If the device could be reached
    "pref_status_cmd": 10, # Preferred status command 
    "status": None, # Reply to the last status request
}

DPS dict

dps = {
    '1': True,
    '2': False,
    '101': 255,
    '102': 128,
    ...etc...
}
