To control a smart bulb using ACS we will implement a python component using the Component Generator tool.
Install dependencies
python -m pip install tinytuya
Create component's YML template
The component generation tool uses a template in YML to create the component's IDL and implementation.
working_dir: ~/workspace prefix: ACSIOT module: acsiot component_name: TuyaBulb functions: - 'void turnOn(in string api_region, in string api_key, in string api_secret, in string device_id)' - 'void turnOff(in string api_region, in string api_key, in string api_secret, in string device_id)'
The "working_dir" is where the component's IDL and implementation directories will be created, the rest is kind of self explanatory 
.
Generate component's IDL and boilerplate code
In short, the component generator tool works as follows:
> python create_acs_component.py --help
Usage: create_acs_component.py [OPTIONS] COMPONENT_YAML_PATH
Creates an ACS component from a YAML definition.
Options:
-l, --language [python|cpp|java]
Component's implementation language.
[default: python]
--version Show the version and exit.
--help Show this message and exit.
So in our case we will run:
> python create_acs_component.py -l python path/to/tuya_bulb.yml
If everything is ok the generator will create the component's IDL and implementation directories and files. Also it will add the component to the CDB. The output will be something like:
Implement component
In order to have a working component in valid python we will have to modify the boilerplate code as follows:
# Client stubs and definitions, such as structs, enums, etc.
import acsiot
# Skeleton infrastructure for server implementation
import acsiot__POA
# Base component implementation
from Acspy.Servants.ACSComponent import ACSComponent
# Services provided by the container to the component
from Acspy.Servants.ContainerServices import ContainerServices
# Basic component lifecycle (initialize, execute, cleanUp and aboutToAbort methods)
from Acspy.Servants.ComponentLifecycle import ComponentLifecycle
import tinytuya
tinytuya.set_debug(True)
class TuyaBulbImpl(acsiot__POA.TuyaBulb, ACSComponent, ContainerServices, ComponentLifecycle):
def __init__(self):
ACSComponent.__init__(self)
ContainerServices.__init__(self)
self._logger = self.getLogger()
def turnOn(self, api_region, api_key, api_secret, device_id):
# raise NotImplementedError("This function should do something")
client = tinytuya.Cloud(
apiRegion=api_region,
apiKey=api_key,
apiSecret=api_secret
)
commands = {
'commands': [{
'code': 'switch_led',
'value': True
}]
}
print("Sending command...")
result = client.sendcommand(device_id, commands)
print("Results\n:", result)
def turnOff(self, api_region, api_key, api_secret, device_id):
# raise NotImplementedError("This function should do something")
client = tinytuya.Cloud(
apiRegion=api_region,
apiKey=api_key,
apiSecret=api_secret
)
commands = {
'commands': [{
'code': 'switch_led',
'value': False
}]
}
print("Sending command...")
result = client.sendcommand(device_id, commands)
print("Results\n:", result)
Build and install IDL
cd idlTuyaBulb/src make all make install
Build and install component
cd pyTuyaBulb/src make all install
Run component
In one terminal run:
acsStop acsStart
In a second terminal run:
acsStartContainer -py aragornContainer
And in a third terminal run:
from Acspy.Clients.SimpleClient import PySimpleClient api_region = 'my_region' api_key = 'my_api_key' api_secret = 'my_api_secret' device_id = 'my_device_id' client = PySimpleClient() bulb = client.getComponent("TuyaBulbPython") bulb.turnOn(api_region, api_key, api_secret, device_id) bulb.turnOff(api_region, api_key, api_secret, device_id)- If everything is ok you should have witnessed how the smart bulb lit on and off using ACS.
