Java PoC: Tuya Smart-Lock API

@flance9

Hello, I hope you're having a great day. I have delivered multiple projects that integrate with vendor cloud APIs and produce clear console logs for debugging. For example, I built a command-line Java PoC that authenticated to a cloud thermostat API, pushed a temporary setpoint, retrieved current schedules to confirm the change, and then revoked the setpoint—all with plain-text request/response logging. My approach: a small Maven Java 21 app using the JDK HttpClient (or Apache HttpComponents if you prefer), environment variables for keys and device ID, explicit request/response logging, and clear README and build/run steps. I would like to request your time to discuss the details. Thank you for considering this. Inderdeep Singh

Hi there, I will build your Java CLI proof-of-concept that authenticates with Tuya Cloud, creates a time-bound temporary password on your Wi-Fi smart lock, lists all existing temporary passwords for confirmation, and then deletes the created password with full removal verification. Every HTTP request and response will be logged in readable plain text directly to the console so you can trace the entire flow. For the Tuya Cloud API integration, I will implement proper HMAC-SHA256 request signing and handle automatic token refresh since Tuya access tokens expire every two hours. Without this, a test session that runs past the token window will fail silently. I will structure the project with Maven and JDK 21, keeping dependencies minimal - likely just Apache HttpClient for cleaner HTTP handling. Each operation (auth, create, list, delete) will be its own separate method so you can easily extend the PoC later. Questions: 1) Which Tuya Cloud data center region are you using (US, EU, China, or India)? This determines the base API URL and cannot be changed after setup. 2) Should the one-hour temporary password be a purely numeric PIN or an alphanumeric code? 3) Do you have a preference between Maven and Gradle, or are you fine with either? Looking forward to your response. Best regards, Kamran

Hi, I can build this PoC exactly as described using clean, minimal Java (JDK 21) with clear request/response logging for full transparency. I’ve worked with REST APIs that require HMAC-style authentication and timestamp-based signatures, so handling Tuya’s cloud auth flow won’t be an issue. The program will authenticate, create a one-hour temporary password, fetch and print the password list for verification, then delete it and confirm removal — all sequentially from the command line. Every HTTP request and raw JSON response will be logged in plain text so you can see exactly what’s happening. I’ll deliver a well-structured Maven project, plus a simple README covering build steps and required environment variables. No heavy frameworks — just lightweight, maintainable code. Once you share API credentials and device details, I can get started immediately.

Hi, I understand you need a clean, command-line Java PoC that authenticates with Tuya Cloud, creates a 1-hour temporary password, verifies it via list retrieval, then deletes it—with every REST request and response logged in plain text for full visibility. I can build this in Java 21 using a lightweight HTTP client (pure JDK or Apache HttpComponents), structured cleanly with clear logging, proper signature handling, and a simple Maven/Gradle setup. You’ll receive complete source code plus a concise README covering environment variables, build steps, and exactly how the create/list/delete flow works against your virtual lock. Looking forward for your positive response in the chatbox. Best Regards, Arbaz T

@billybryan98

Hello, I hope you are doing well. I'm an independent Java developer with a strong focus on clean, testable code and robust REST integrations. I’ll build a small Java 21 CLI app that authenticates to Tuya Cloud, creates a one-hour temporary password on a specified lock, lists passwords, and then deletes the one I created, logging every request and response in plain text for full visibility. The solution will compile with Maven or Gradle and run from the command line without a UI. In similar PoCs, I’ve implemented end-to-end REST flows with thorough error handling and transparent logging using standard JDK HttpClient or lightweight libraries. I’ll keep the code modular, document environment variables (keys, device IDs), and provide a README with build/run steps. I can deliver a clean, working PoC with a concise README within the requested budget, and I’ll ensure each REST call and response is captured in the console. I’ll start once you confirm the API endpoints and test credentials. Please feel free to contact me so we can discuss more details. I am looking forward to the chance of working together. Best regards, Billy Bryan

@fighter6869

Hi, I can build a clean command line Java proof of concept that talks directly to Tuya Cloud API and drives the full temporary password lifecycle on your Wi-Fi lock with plain text logging for every request and response. I have shipped multiple API driven command line tools in Java and I will implement Tuya auth, create a one hour temporary password, list and print all existing codes to confirm it, then delete the same code and verify it is gone. You will get well structured Java 21 source, a minimal Maven or Gradle build, and a short README covering environment variables like access key, secret, device ID, plus exact run commands. I will also include clear console logs that make it easy to trace signatures, headers, payloads, and responses end to end for debugging. If you share the device ID and confirm whether you want pure JDK HttpClient or Apache HttpComponents, I can start immediately and deliver the working create list delete flow against your virtual device. Thanks.
