I'm looking for an Android developer to create an application that manages hardware devices via an existing MQTT broker. This app will be crucial for monitoring several devices, sending control commands, to many different devices and reading data back from the devices. Key App Functionalities: - Device Monitoring: The app will communicate using MQTT protocol with multiple devices (up to 20). Each device will provide several values which must be shown in specified fields. - Control Commands: Users of the app will be able to send specific commands to these devices. The user will be able to send configuration data to hardware devices by sending (publish) a fixed structure data type on a topic according the registered devices. - Data Logging: The app will collect and log data from these devices for analysis. The hardware devices will send data to MQTT server in fixed intervals (for example every 3minutes) and this interval value will be adjustable from a settings menu. User Interface: - The app should have a clean, intuitive Graphical User Interface (GUI). -I will provide the design structure so you will have already the component arrangements. - The user will be able to capture a picture from his phone's camera and use the picture as a reference of each device. Moreover, there must be a name field so that the user can give a name to every registered device. - The user will be able to register a new device in the app, using a unique UID number. The registration will be done either by manually enter the UID number or by scanning a QR code containing the UID number. - The user will be able to select a device from a list of all registered devices. The current selected device, must use it's UID to connect to the mqtt server and request data from a specific topic based on it's UID. - The app after requesting and receiving data from mqtt server, will obtain the data on the equivalent fields. - The app will receive data only from registered devices. Therefore a topic subscription is necessary for receiving data. The subscription will be based on the registered UID. - The app should use background service in order to handle push notifications and inform user in case of an error on the actual hardware. Platform Compatibility: - The application should be built for Android and if possible for IOS. Ideal Skills and Experience: - Extensive experience in Android development. - Familiarity with MQTT protocol and brokers. - Previous work with device management apps is a plus. - Strong skills in designing user-friendly GUI. - Experience in data logging and monitoring applications. DETAILS FOR THE DATA STRUCTURE AND COMMUNICATION COMMANDS WILL BE PROVIDED The application should be build with and accessible development environment and all the project files must be provided after the completion in case for further app development or future updates.

Hello, I understand you're looking for an Android developer to create an MQTT broker-based hardware manager app that can monitor and control multiple devices seamlessly. My approach will focus on implementing the MQTT protocol effectively to ensure reliable communication with up to 20 devices. I'll develop a clean and intuitive GUI based on the design structure you provide, making it easy for users to manage their devices, send commands, and log data efficiently. Also, integrating features like capturing device reference images and UID registration through QR scanning will enhance user experience. I will ensure that the app runs smoothly both on Android and potentially iOS, while also implementing a background service for notifications about hardware errors. What specific MQTT broker do you plan to use, and are there any particular security measures you want implemented for device communication? Thanks, Muhammad Awais

Hello, I understand you’re seeking an Android (and optionally iOS) app to manage multiple hardware devices via an MQTT broker, enabling real-time monitoring, control commands, and data logging. I have strong expertise in Android development, MQTT protocol integration, and IoT device management applications, ensuring secure, stable, and user-friendly solutions. I will develop the app with a clean GUI based on your provided design, allowing device registration by UID (manual or QR scan), assigning names, and attaching photos for reference. Each device will subscribe to its UID-specific topic, receiving data only from registered units. The app will display live values, allow fixed-structure command publishing, and adjust reporting intervals from settings. A background service will manage push notifications for error alerts, while periodic logging will store and organize readings for analysis. The solution will be optimized for handling up to 20 devices, with secure MQTT connections and efficient data handling. Deliverables will include all source files, full documentation, and a scalable architecture for future updates. My past work in IoT, MQTT-based control, and cross-platform systems ensures I can deliver a robust, maintainable application tailored to your hardware ecosystem. Best regards, Asif

✋ Hi there. I can develop your MQTT Broker-based Hardware Manager, ensuring seamless device communication and management. ✔️ I have extensive experience in building MQTT-based systems. For instance, I previously developed a custom MQTT device manager to monitor soil moisture and climate sensors for indoor plants. This project involved collecting, monitoring, alerting, and storing MQTT data submitted through a broker across multiple devices . ✔️ To develop this project, I will first analyze your hardware specifications and communication requirements. I will then design a system architecture that includes setting up an MQTT broker, configuring devices to publish and subscribe to relevant topics, and implementing a backend to manage device states and data storage. The system will be designed to handle multiple devices and ensure reliable message delivery. ✔️ Post-development, I will thoroughly test the system to ensure all devices communicate as expected. I will also provide documentation and training to your team, enabling them to manage and monitor the system effectively. Let's chat to discuss your specific requirements and how I can assist you in building this hardware manager. Looking forward to working with you! Best regards, Mykhaylo
