How to Control Multiple WiFi Smart Ball Valves Simultaneously? (Part2)

Programmatic Device Control Solution
While cloud platforms provide basic device management capabilities, our programmatic approach offers more flexible and direct control over your smart ball valves. This method is particularly useful for automation scenarios, custom integrations, and bypassing cloud latency.

Development Environment 
This demonstration utilizes Visual Studio Code for its excellent Python support and debugging capabilities. However, the program is platform-agnostic and can be deployed with:
PyCharm (recommended for Python-centric development)
Jupyter Notebooks (for experimental configurations)
Any Python 3.9+ compatible IDE

Note: Before using the program, you need to pre - download the Tuya database on the operating device.
# Install TinyTuya Library
python -m pip install tinytuya

Implementation Steps
1. Configuration Setup
 Locate and populate the following parameters in the designated configuration section (as shown in the video tutorial):
 API Region: Geographic zone of your cloud service (e.g., "CN", "EU", "US")
 API Key: Unique application identifier (64-bit hexadecimal)
 API Secret: Authentication token (256-bit encrypted string)
 Device ID(s): Comma-separated list of target devices (Minimum 1 required)

Note: Detailed parameter acquisition instructions are available in Part 1 of our technical blog series. Always store credentials in environment variables for production use.

2. Execution Protocol
   Initiate the control sequence using either:
   The ▶️ "Run and Debug" button (F5 shortcut)
   Terminal command: "python3 ballvalve_controller.py --auto"
   The system will automatically:
   Establish secure TLS 1.3 connections
   Validate credential permissions
   Initialize device communication channels

3. Stateful Control Logic  
   Our dynamic control engine implements:  
   python
   Pseudo-code of core logic
   def toggle_device(device):
       current_state = poll_status(device)
       new_state = not current_state
       send_command(device, new_state)
       verify_state_change(device, new_state)
   Key features:  
   Real-time status polling 
   Bidirectional state verification
   Automatic retry mechanism
   Graceful error handling 

Operational Scenarios 
This program enables:  
✅ Scheduled irrigation systems  
✅ Emergency shutdown protocols  
✅ Multi-device synchronization  
✅ Integration with SCADA systems  

Safety Considerations
Always test in staging environment first  
Maintain firmware version v2.3.8+  
Implement circuit breaker pattern for bulk operations  
Monitor API call quotas (max 60 RPM/default account)
