ATM90E32 Energy Monitor Integration

@elect2eng

I can write program for wemos to read the data from energy monitoring IC. Please let me know how do you want to select the menu, Is it using 3 buttons or something else. UP/down/enter. please provide me all information to start the project. This quotation is for the fist phase. after this we will discuss about the second phase.

Hello, I can interface ESP8266 (Wemos Mini) with ATM90E32 for accurate energy data with 20x4 LCD multi-menu display. I have experience in metering ICs, SPI communication, and noise-robust embedded design. For Phase 2, I’ll design a compact, reliable PCB with proper isolation and layout practices to ensure measurement accuracy and safety. Estimated timeline: 5-7 days. Ready to start immediately.

Hi, We have extensive experience in embedded development and firmware engineering, which makes us a strong fit for both phases of this project. We’ll interface the Wemos Mini with the ATM90E32 over SPI, pull all key parameters — voltage, current, power, power factor — and build a clean multi-menu navigation system on the 20x4 LCD with stable and accurate readings. For the PCB phase we’ll design a compact board with proper isolation between the high-voltage measurement side and the logic side, ensuring layout accuracy and clean manufacture-ready output files. Happy to discuss timeline once you share the PCB tool preference and any specific parameters or menu structure you have in mind. Send over the details and we can get started.

I have hands-on experience with ESP8266/ESP32 firmware, SPI-based sensor integration, and real-time data display — including a deployed cold storage monitoring system with multi-channel sensor acquisition, real-time parameter display, and threshold-based control logic. Reading metering IC registers over SPI and presenting clean, navigable data on an LCD is work I've done before. I have ESP8266 Wemos Mini, 20x4 LCD modules, and relay components in stock — ready to build and test on real hardware immediately. Phase 1 I will deliver: • Stable SPI driver for ATM90E32 — correct calibration register initialisation, line frequency config, and gain settings • Accurate readings for Voltage, Current, Active/Reactive Power, PF, Energy — validated against a known load • 20x4 LCD multi-menu navigation (button-driven or encoder) with clean screen layouts per parameter group • Clean, commented Arduino/C++ codebase ready for Phase 2 PCB integration Phase 2: compact KiCad PCB with proper isolation between HV measurement side and logic side, layout optimised for measurement accuracy. Delivery in 4 days for Phase 1. Once tested and verified on hardware, I will ship the working prototype to you. Are you using CTs for current sensing or direct shunt measurement, and is this single-phase or 3-phase?

Hi, This is a very interesting project — I have hands-on experience with IoT systems, PCB design, and embedded hardware, including energy monitoring and ESP-based solutions. I can support both phases of your project: Phase 1 – Communication & Data Acquisition Interface ESP8266 (Wemos D1 Mini) with ATM90E32 via SPI Reliable reading of voltage, current, power, power factor, and energy parameters Implementation of a structured multi-menu system for a 20x4 LCD Focus on stable communication and accurate measurements Phase 2 – PCB Design Compact and manufacturable PCB design Proper isolation between high and low voltage sections Clean layout for signal integrity and measurement accuracy I focus on delivering working, production-ready solutions, not just prototypes. I’d be happy to discuss your requirements in more detail and suggest the best approach for a scalable system. Best regards,

Hi there, I have extensive experience in embedded systems and PCB layout, specifically working with ESP32/ESP8266 environments and various energy metering ICs. I can deliver a robust, scalable solution for your ATM90E32 project. My approach for your requirements: Phase 1: I will implement a stable SPI interface between the Wemos Mini and ATM90E32, handling the calibration registers for precision. I’ll develop a non-blocking multi-menu system for the 20x4 LCD to ensure the UI remains responsive while data is polled. Phase 2: For the PCB, I focus on signal integrity and safety. I will implement proper high-voltage isolation, optimized ground planes for the analog front-end, and a compact form factor suitable for enclosures.(this will be charged separately) I am proficient in Arduino/C++ and KiCad for professional-grade hardware design. Let’s discuss your specific accuracy requirements and sensor scaling!
