I need a fully-working prototype that can pick up wMBus S, T and C-mode frames from household utility meters, decode the consumption values only, and push them straight into my Tuya account so they show up in the standard Tuya Smart / Smart-Life app on both Android and iOS. Hardware I want to stick with: • ESP8266 or ESP32 for Wi-Fi and Tuya connectivity • CC1101 (868 MHz) as the RF front end for wMBus Your job is to design the firmware and, if necessary, a minimal reference schematic so I can have the board assembled locally. The device has to stay OTA-upgradable through Tuya, publish the consumption data at user-defined intervals, and appear as a normal energy-type device inside the existing Tuya app—no custom mobile development required. Deliverables 1. Source code for ESP8266/32 and CC1101 showing clean separation between wMBus decoding and Tuya IoT SDK calls. 2. Pinout / BOM and a one-page wiring diagram suitable for a quick PCB spin. 3. Instructions for flashing, pairing with Tuya, and verifying that live consumption values update in the app. 4. Confirmation test report based on at least two real wMBus meters. Acceptance will be based on my ability to compile, flash, pair and read accurate consumption figures in the Tuya app without additional tools.

Hello, I understand you need a fully working ESP8266/ESP32-based meter reader that captures wMBus S, T and C frames with a CC1101 868 MHz front end, decodes only the consumption values, and sends them into your Tuya account so they appear in the Tuya Smart/Smart-Life app on Android and iOS. I will build a clean firmware with a clear separation between wMBus decoding and Tuya IoT SDK calls, plus a minimal reference schematic for a quick board build. The solution will support OTA updates via Tuya, publish at user-defined intervals, and present as a standard energy device in the Tuya app. Deliverables: 1) source code for ESP8266/32 and CC1101 with modular, maintainable structure; 2) pinout, BOM and a one-page wiring diagram for a quick PCB spin; 3) flashing/pairing instructions and verification steps; 4) a test report based on at least two real wMBus meters. I will keep the code straightforward, portable, and well-documented, with practical testing guidance to reproduce live readings. Which Tuya account region and device type should we target, and is there a preferred interval for publishing live consumption values?

⭐⭐⭐⭐⭐ Hello Valuable Client, CnELIndia, led by Raman Ladhani, can deliver this end-to-end wMBus–to–Tuya prototype exactly as specified. We will design robust ESP8266/ESP32 firmware interfacing with the CC1101 at 868 MHz to reliably receive wMBus S, T, and C-mode frames, decode only validated consumption values, and map them to standard Tuya energy datapoints so they appear natively in the Tuya Smart / Smart-Life apps on Android and iOS. Execution approach: Architecture & RF layer: Configure CC1101 for multi-mode wMBus reception, implement frame handling and CRC validation, and build a clean decoder module isolated from cloud logic. Firmware & Tuya integration: Integrate Tuya IoT SDK with OTA support, user-defined publish intervals, and energy-type device modeling—no custom app work required. Hardware reference: Provide a minimal, production-ready schematic, pinout, and BOM optimized for local PCB assembly. Validation: Test with at least two real household wMBus meters and document accuracy and stability. Handover: Clear flashing, pairing, and verification instructions plus a concise confirmation test report. This ensures you can compile, flash, pair, and read accurate consumption data in Tuya—smoothly and reliably.

Hello, I’m an embedded systems and IoT developer with 8+ years of experience building Wi-Fi–connected metering and RF data acquisition devices, and I’ve carefully reviewed your Tuya wMBus meter reader requirements end to end. I’ve delivered 15+ ESP8266/ESP32 firmware projects, including 6 RF-based integrations using sub-GHz transceivers (CC1101 / SX127x) to decode real-world utility and sensor data. For this project, I’ll design a cleanly layered firmware architecture separating wMBus S/T/C-mode decoding from Tuya IoT SDK communication, ensuring OTA updates and long-term maintainability. I’ve previously implemented wMBus frame parsing and payload extraction with verified accuracy against physical meters, focusing strictly on consumption values to keep processing efficient and reliable. I will provide a minimal, production-ready schematic (pinout + BOM) suitable for a 1–2 layer PCB, and firmware tested on at least two real household meters before delivery. Data publishing intervals will be user-configurable, and the device will appear as a standard Tuya energy-type device inside the Smart Life app—no custom mobile work needed. You’ll receive compilable source code, flashing and pairing instructions, and a concise validation report, so you can reproduce results independently. If helpful, please confirm whether your Tuya account is already set up for custom MCU SDK access or if device PID creation is still needed on your side.
