Tuya Smart Bidirectional Single‑Phase Wi‑Fi Energy Meter with 150 A Clamp Current Sensor Key benefits Measures energy flow in both directions: accurately records electricity drawn from the grid and electricity fed back to the grid. Ideal for systems with generation (for example rooftop solar) where you need separate tracking of consumption and export. Real-time remote monitoring via Wi‑Fi and integration with the Tuya Smart ecosystem allows you to check usage, production, and trends from your phone — helpful for reducing costs and optimizing consumption. Clamp‑on 150 A current sensor enables non-invasive installation on single‑phase mains without rewiring the conductor, supporting residential and small commercial single‑phase installations. What it does and why you need it Bidirectional measurement: distinguishes energy "from the grid" and "to the grid" so you can measure net usage and exported generation for billing, performance verification, or energy management. Continuous monitoring: shows instantaneous power and cumulative energy values so you can spot abnormal usage, evaluate the effect of appliances or generation changes, and make informed decisions. Remote access and basic automation: pair with the Tuya Smart app for remote monitoring, logging and simple automations within the Tuya ecosystem. Main features and attributes Function: Bidirectional energy metering for single‑phase systems (measures consumed and generated energy). Connectivity: Wi‑Fi enabled for remote monitoring via Tuya Smart. Sensor: Clamp (current transformer) type with 150 A rating for non-intrusive installation on single‑phase mains. Compatibility: Designed for single‑phase electrical systems and integrates with Tuya Smart platform for monitoring and basic smart‑home workflows. Installation: Clamp-on CT simplifies setup; suitable for main incoming conductors within the sensor’s current rating. Performance: Supports continuous bidirectional measurement and remote reporting through the Tuya Smart app. Practical use scenarios Residential solar system: Monitor how much solar energy your panels produce and how much you export to the grid versus self-consume, enabling better decisions about storage or load shifting. Home energy management: Track appliance-level behavior indirectly by watching whole-house consumption trends, helping you cut costs and identify unexpected increases in usage. EV charging and small commercial sites: Measure charging load or machinery consumption on a single‑phase supply and determine whether you are importing or exporting energy during operations. What to check before purchase Ensure your installation is single‑phase and that the main conductor carrying the current is within the 150 A clamp sensor rating. Confirm Wi‑Fi connectivity and compatibility with the Tuya Smart ecosystem in your region. This Tuya Smart bidirectional single‑phase Wi‑Fi energy meter with 150 A clamp current sensor provides clear, remote‑accessible measurement of both consumption and export, supporting practical energy management for homes and small installations.
