Tuya Smart WiFi Bi‑directional Single‑Phase Meter — concise product description and benefits What it does Measures energy flow in both directions (bi‑directional) for single‑phase systems: tracks both electricity consumed from the grid and electricity generated by a solar installation. Uses two current transformers (2 CT) to provide accurate measurement of generation and consumption. Connects to Tuya Smart WiFi for remote monitoring through the Tuya-compatible app. Built-in buzzer and overload alarm to alert on abnormal conditions and potential load problems. Key benefits — why you need it Accurate energy accounting: Separate measurement of generated and consumed energy helps validate solar production, optimize self-consumption, and support billing or reporting needs. Faster problem response: The onboard buzzer plus overload alarm provides immediate local notification of overload conditions, reducing risk to equipment and helping prevent downtime. Remote visibility and control: App monitoring gives convenient access to meter readings and status from anywhere, enabling proactive energy management without physical meter checks. Simple integration into existing single‑phase systems: Designed for use with single‑phase installations and the Tuya Smart ecosystem, so it fits common residential and small commercial setups. What makes it stand out Bi‑directional metering capability that distinguishes between export and import energy. Two CT inputs improve measurement fidelity for both generated and consumed energy. Combined local (buzzer/alarm) and remote (app) alerts for comprehensive monitoring and safety. Compatibility and function Intended for single‑phase electrical systems. Works with Tuya Smart WiFi infrastructure and Tuya‑compatible mobile app for monitoring and alerts. Requires use of the provided 2 CTs (current transformers) for accurate measurement of both directions of energy flow. Performance and reliability Dual CT arrangement reduces measurement error when tracking generation and consumption separately. Overload alarm and buzzer provide immediate audible/local warning to complement app notifications. Practical use scenarios 1) Residential rooftop solar: Install between the inverter and home distribution to measure how much solar energy you produce, how much you feed back to the grid, and how much you draw. Use the app to check generation trends and confirm correct inverter operation. 2) Solar plus battery or hybrid systems: Monitor exported energy and imported consumption to tune charge/discharge schedules, improve self‑consumption, and detect unusual loads or overloads quickly via alarm. 3) Small commercial single‑phase service: Track energy flows for cost allocation or simple energy audits, and receive audible/remote alerts when loads approach or exceed safe limits. Installation notes (practical considerations) Designed for single‑phase connections; ensure wiring and CT placement follow local electrical codes and installer guidance. Two CTs must be installed correctly to measure both generation and consumption as intended. Configure the Tuya app to receive remote readings and alarm notifications. What you get A Tuya Smart WiFi bi‑directional meter for single‑phase systems with 2 CT inputs, overload alarm, and buzzer, plus app-based monitoring for convenient access to measurements and alerts.
