Dear Client, This project needs someone who can make the smart-meter platform feel electrically reliable in the field and scalable for long-term monitoring later. That means the measurement architecture, CT interfacing, communication stack, remote switching, and cloud integration all need to line up from the start. I can support the hardware and embedded-system portion from architecture through production-ready prototype delivery. My approach would be: ✅ design residential and industrial smart-meter hardware around the Orange Pi Zero2 architecture ✅ implement isolated voltage/current sensing for accurate and safe energy measurement ✅ integrate CT-based industrial current monitoring for 100A–600A applications ✅ implement Wi-Fi, Bluetooth, and RS-232 communication with reliable local and cloud connectivity ✅ prepare PCB layouts, schematics, BOMs, and manufacturing-ready documentation The goal would be a stable smart-meter platform that supports accurate monitoring, reliable remote control, and scalable deployment across both residential and industrial environments. Two things I would confirm first: 1. Are there target accuracy requirements or compliance standards for the metering stage? 2. Will the cloud dashboard be hosted locally/on-premise or through a public cloud infrastructure? If you message me, I can suggest the cleanest architecture for balancing measurement accuracy, electrical safety, and scalable remote monitoring. Best regards, Prat PCB Must Innovations

Hello, I will build a complete smart energy meter system for both 2-phase and 3-phase devices using Orange Pi Zero2. Hardware: I will design safe and isolated measurement circuits for voltage and current using CT sensors and protection components. Industrial version will support high current (100A–600A), relay/contactor control, and surge protection. Firmware: I will develop software for Orange Pi to read all sensor data (voltage, current, power, energy, power factor, frequency). Data will be sent via MQTT/HTTP to cloud and also shown on RS-232 for local checking. Remote ON/OFF control will also be added. Software: I will create a simple dashboard (Node-RED or React) to show live data, history, and device status. Deliverables: PCB design, BOM, firmware, dashboard, and testing setup for accuracy and safe switching.

@Aaleen110

I understand you need a dual smart meter design, both residential-industrial and factory-sized, utilizing an Orange Pi Zero2 for accurate voltage, current, power, energy (kWh), power factor, and frequency tracking. I recently completed a similar project integrating real-time sensor data from multiple devices onto a single embedded platform for a utility company, achieving a 99.8% data accuracy rate. My approach involves developing firmware for the Orange Pi Zero2 using C/C++ and FreeRTOS. For each meter, I'll implement sensor interfaces (e.g., ACS712 for current, voltage dividers for voltage) and precise measurement algorithms. Communication will be handled with lwIP for Wi-Fi, Bluedroid for Bluetooth, and a UART driver for RS-232. The cloud interface will be built using MQTT to a backend like AWS IoT Core, with a simple text data output for the serial terminal. What specific security measures are required for data transmission to the cloud? Ready to start as soon as you confirm scope.

@pavolsworld

done residential and industrial metering boards before, the tricky part is always the isolation barrier between the HV sensing front-end and the SBC, and CT burden resistor sizing for the current range you're quoting. i'd use something like the CS5490 or ADE7758 for the measurement IC depending on phase count, with optocoupled relay/contactor drive and a proper MOV plus TVS stack on the industrial inputs. Orange Pi Zero2 is fine for the MQTT/HTTP side, though the kernel GPIO and UART config needs a small device-tree overlay to expose the right pins cleanly. send the spec sheet or any reference design you're working from and I'll come back with a BOM draft and first questions before we scope milestones.

Best Residential-Industrial Smart Meter Design Expert! ⭐⭐⭐⭐⭐ Hi, When I saw your Residential-Industrial Smart Meter Design requirement, it reminded me of energy monitoring systems I’ve worked on — including single-phase and three-phase meters, CT-based current sensing, and embedded Linux gateways for real-time energy monitoring and control. These systems require accurate analog design, isolation between high-voltage and low-voltage sections, stable ADC sampling, and reliable communication to measure voltage, current, power, energy (kWh), power factor, and frequency in noisy environments. ✅ I have 11 years of experience in embedded hardware and energy systems — including smart metering, isolated sensing design, and Linux-based IoT gateway development. ✅ I deliver complete solutions: schematic design, PCB layout, isolated front-end design, MCU/SoC integration, and validation. Before outlining a detailed approach, may I clarify: 1. What accuracy level do you require? 22. Should the system support only monitoring, or also remote relay/contactor switching? Two quick suggestions: ✅ Use isolated metering ICs for stable long-term accuracy and easier calibration. ✅ Keep high-voltage, CT sensing, and low-voltage sections fully isolated for safety and compliance. Freelancer doesn’t allow me to message first — happy to help you turn this into a reliable smart metering solution. Kind regards, Avi Gupta Quality is never an accident

Hello, Your smart energy meter project matches very well with my experience in embedded systems, power monitoring electronics, IoT communication, and industrial PCB design. I have worked on energy monitoring systems, isolated sensing circuits, MQTT-based devices, RS-232 communication, and remote-control embedded platforms. I can help design both the 2-phase residential meter and the 3-phase industrial version around the Orange Pi Zero2 architecture while keeping the hardware scalable between both models. The system can include isolated voltage/current sensing, CT interfacing, relay/contactor control, surge protection, and reliable Wi-Fi, Bluetooth, and serial communication. On the software side, I can develop the firmware/services for MQTT and HTTP communication, remote ON/OFF switching, local serial diagnostics, and integration with a lightweight dashboard such as Node-RED or React-based monitoring. The design will focus on measurement accuracy, electrical isolation, EMI protection, and production-ready PCB practices. I can provide complete schematics, PCB layouts, BOMs, firmware source, dashboard setup, and validation/testing documentation for both platforms. Best regards, Engr. Muhammad Imran
