Hi there, I understand you want an automated ON/OFF scheduling system for the Pro Aqua NTS air cleaning device that works through a backend, without modifying the device firmware or the official app. I will analyze the current communication between the device and the app, map the API and network flows, and design a backend solution that triggers the device’s power cycle on a schedule. I will propose a clean architecture, build a working prototype, and prepare deployment-ready docs. The plan includes optional smart home integration (Google Home, Alexa, Home Assistant), remote control, and a simple web or lightweight mobile UI if needed. The placeholder What is the exact Pro Aqua NTS model and firmware version in use? Which mobile app and backend endpoints are currently used to turn the device on/off, and what is the expected response format? Do you have any existing network capture data (Wireshark/MITM) or logs to help map the API? Are there any constraints on reverse engineering or legal considerations we must respect? What hosting or cloud preferences do you have for the backend (AWS/GCP/Azure or self-hosted)? Which smart home ecosystems do you want prioritized (Google Home, Alexa, Home Assistant) and any regional limitations? What authentication and security requirements should the backend meet (OAuth, API keys, TLS)? What is the expected scale (devices, users) and uptime requirements for the service? Do you want a simple web UI or a lightweight mobile UI,

Hello! I can help you design a backend-driven automation layer for the Pro Aqua NTS that enables scheduled ON/OFF control without modifying firmware or the official app, while keeping the solution stable and maintainable. Here’s how I’d approach it: • Phase 1 – Feasibility & Protocol Analysis Capture and analyze device ↔ app traffic (TLS inspection where legally permissible, DNS tracing, endpoint mapping) Identify whether control happens via cloud API or local LAN protocol Determine authentication model (token-based, device ID, session keys) Produce a documented control-flow diagram • Phase 2 – Architecture Proposal Depending on findings: Cloud API bridge (if device talks to vendor servers) Local LAN controller (if device exposes local endpoints) Middleware service (Node.js or Python) handling auth refresh, scheduling logic, and retry handling MQTT layer for smart home interoperability Optional Google Home / Home Assistant integration • Phase 3 – Automation Layer Cron-based scheduler with timezone safety Idempotent ON/OFF commands Health monitoring and fallback logic Optional lightweight web dashboard If software control proves impossible, I can propose a hardware fallback (smart relay/plug with power-state awareness), but that would be secondary to API-level control. Let’s open the chat and confirm whether the device communicates locally or strictly via vendor cloud, as that determines the cleanest automation path. Best regards, Jasmin

Hi, I’ve carefully reviewed your requirement. Since firmware modification is off the table, the project clearly revolves around protocol analysis and building a clean middleware automation layer — not hardware hacking. I’m Sanyam, CEO of Eplanet Soft. Our team has experience in IoT integrations, API reverse engineering, and automation bridges for closed ecosystems using Node.js and Python-based middleware. Proposed approach: Phase 1 – Feasibility & Analysis • Network traffic inspection (MITM/Wireshark) to analyze app-device communication • Identify authentication flow, endpoints, and control payloads • Validate whether local or cloud-based API control exists Phase 2 – Architecture • Build a secure middleware service (Node.js/Python) • Implement timer-based scheduler (cron-based or event-driven) • Optional MQTT bridge for Home Assistant / Google integration • REST layer for remote control Phase 3 – Delivery • Working prototype • Deployment-ready backend • Documentation (setup, maintenance, scalability) If API-level control is blocked, we can evaluate a smart-relay fallback as a controlled hardware alternative. Before proceeding: Is the device cloud-dependent or locally networked? iOS, Android, or both? Do you have access to multiple test units? Happy to discuss feasibility before commitment. Best regards, Sanyam

Hey, I will intercept the app's traffic with mitmproxy, map the auth flow and ON/OFF command payloads, then build a Python backend that replays those commands on a timer. If the app uses certificate pinning, I will decompile the APK and patch it out first. The feasibility analysis comes first whether the device talks to a cloud API or over local WiFi determines the whole architecture. Cloud means a middleware replaying API calls on schedule; local opens the door to Home Assistant with MQTT directly. Questions: 1) Cloud-controlled or local WiFi between app and device? 2) Can you share the app name or Play Store link for early APK analysis? Looking forward to discussing further.

Hi, this is an interesting project and I’d be glad to help. I have 5+ years of experience in full-stack and mobile development (PHP, Android, iOS) and solid hands-on work with API analysis, network inspection, and backend automation systems. For your Pro Aqua NTS device, my approach would start with a technical feasibility study: analyzing the mobile app traffic, identifying the communication protocol, and reverse engineering the API flow (using MITM/Wireshark where applicable). Based on findings, I would design a secure middleware service to enable timer-based ON/OFF scheduling, remote control, and optional smart home integration (Google Home / Home Assistant / MQTT). If direct software control is limited, I can also propose a reliable hardware fallback (smart plug/relay) while keeping the system automation-ready. You will receive a working prototype, clean architecture, deployment setup, and clear documentation for maintenance and scalability. I focus on practical, stable solutions and clear communication. I can share similar automation/backend work once we connect and would be happy to discuss the device details to validate feasibility quickly. Best, Bhargav

Your Pro Aqua NTS project will fail if the device uses certificate pinning or encrypted payloads - most modern IoT manufacturers implement these to block exactly what you're trying to do. Before investing in development, we need to confirm the app's traffic is interceptable and the API endpoints accept unauthenticated requests. Quick question - have you already captured any network traffic from the official app using a proxy tool like Charles or mitmproxy? And does the device communicate directly with a cloud server or does it use local Bluetooth/WiFi first? These two factors determine whether we build a cloud API bridge or a local MQTT gateway. Here's the architectural approach: - REVERSE ENGINEERING: Use Frida to hook into the Android app's SSL layer and bypass certificate pinning, then capture the authentication flow and command structure with Wireshark. This reveals whether they're using REST, WebSockets, or proprietary protocols. - BACKEND AUTOMATION: Build a Python-based middleware service that mimics the official app's authentication headers and replicates the ON/OFF commands. Deploy on a Raspberry Pi or AWS Lambda with cron jobs for scheduling. - API DEVELOPMENT: Create a REST API wrapper around the reverse-engineered endpoints so you can trigger device control from any platform - web dashboard, Home Assistant, or Google Home via webhook integration. - SMART HOME BRIDGE: Implement an MQTT broker that translates your REST commands into Home Assistant-compatible entities, enabling voice control and automation rules without touching the device firmware. - FALLBACK HARDWARE: If the protocol proves too locked down, integrate a Shelly relay on the device's power supply with local API control - not elegant but guarantees scheduling works. I've reverse engineered 8 closed IoT ecosystems including Tuya-based devices and proprietary air purifiers. The success rate depends entirely on their security implementation. Let's schedule a 20-minute technical call to analyze the app's network behavior before committing to a build - I don't take projects where the protocol might be unbreakable.
