Tuya ESP WMBus Meter Reader

@AwaisChaudhry

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, I have reviewed your requirements and understand the full scope of building a Tuya-compatible wMBus meter reader using ESP8266/ESP32 + CC1101. With 10+ years of embedded and IoT development experience, I can deliver a working prototype with clean firmware architecture, reliable wMBus S/T/C decoding, and seamless Tuya IoT integration so the device appears as a standard energy meter in Tuya Smart / Smart Life. I will provide the full source code, pinout/BOM, wiring diagram, and step-by-step flashing and pairing instructions. The device will support OTA updates through Tuya, configurable reporting intervals, and accurate consumption publishing. I will also validate with at least two real meters and provide a confirmation test report. I WILL PROVIDE 2 YEAR FREE ONGING SUPPORT AND COMPLETE SOURC CODE, WE WILL WORK WITH AGILE METHODOLOGY AND WILL GIVE YOU ASSISTANCE FROM ZERO TO PUBLISHING ON STOIRES. I eagerly await your positive response. Thanks

@OutsourceMan

⭐⭐⭐⭐⭐ 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.

@SMBelectronics

Hey there, This is a very specific and practical build, and I like that you’ve kept the scope focused. wMBus decoding plus Tuya integration is not generic IoT work — the tricky part is cleanly separating RF decoding from the Tuya device model so OTA and app behavior stay intact. I’ve worked on ESP8266/ESP32 devices using sub-GHz radios (including CC1101-class parts), protocol decoding, and pushing structured data into cloud platforms without custom apps. I’m comfortable handling wMBus S/T/C modes, consumption-only parsing, and mapping that cleanly into Tuya’s energy device model. I can deliver firmware that’s structured, OTA-safe, and easy to extend, plus a minimal reference schematic/pinout so you can spin a quick board locally. Rather than guessing details, I’d like to confirm which Tuya SDK path you’re using and what meters you already have access to on a quick chat. If this sounds aligned, message me using the chat button. P.S. Visit my profile to see similar RF + ESP32 + cloud-connected device work I’ve done.

From my extensive experience in Website and Mobile App development (including with Java, PHP, Android and iOS), I believe I would be a perfect fit for your Tuya ESP WMBus Meter Reader project. Not only have I garnered over 9 years of hands-on experience in the field, but I am also skilled in firmware design, giving me the competency to meet your hardware needs using ESP8266 or ESP32 for Wi-Fi and Tuya connectivity along with CC1101 (868 MHz) as the RF front end for wMBus. I have successfully developed numerous apps that integrate seamless connectivity and well-tailored IoT setups such as this. My firm's emphasis on clean code separation aligns directly with your requirement for a clear distinction between wMBus decoding and Tuya IoT SDK calls. In addition to providing a one-page wiring diagram suitable for quick PCB spin, pinout / BOM, source code for ESP8266/32 and CC1101 (with OTA-upgradability) and thorough instructions, my extra services of cost-effective solution, compatibility assurance and post-delivery support can provide further value. Finally, based on my strong skill set in mobile app testing among other proficiencies like SEO Services and Logo Design that might enhance your project’s completion, I am confident that my proposed designs will not only compile and flash excellently but also update live consumption data accurately giving you no need for additional tools to verify these figures through utmost efficien

@Feriver

Hello, I understand you’re looking for a fully working prototype that reads wMBus S, T, and C-mode frames from household utility meters, decodes consumption values, and publishes them directly into the Tuya ecosystem as a standard energy-type device. I have experience with ESP8266/ESP32 firmware, CC1101 RF integration at 868 MHz, and cleanly structured embedded code that separates protocol decoding from cloud/SDK communication. I will deliver firmware that reliably captures and parses wMBus frames, extracts only the required consumption data, and pushes updates to Tuya at configurable intervals while remaining OTA-upgradable through Tuya’s platform. Alongside the code, I will provide a minimal reference schematic, BOM, and wiring diagram suitable for local PCB assembly, plus clear instructions for flashing, pairing, and verification in the Tuya Smart / Smart Life app. The focus is a reproducible, stable build that you can compile, deploy, and validate independently.

@julianm260

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.
