Tuya Zigbee Single-Phase Energy Monitor with CT Clamp

Clips onto your existing mains cable at the consumer unit and reports your whole-home electricity consumption in real time — no electrician needed, no rewiring. The 80A CT clamp fits around a single-phase live cable and feeds live watt, voltage, current, and cumulative kWh data to your Zigbee hub every few seconds.

Reviewed positively on SmartHomeScene and well-supported in Zigbee2MQTT and ZHA. A practical first step for anyone wanting to track standby draw, spot energy hogs, or trigger automations based on whole-home load.

• Protocol: Zigbee 3.0
• CT clamp: 80A (suitable for most UK single-phase homes)
• Measures: Real-time watts, voltage, current, cumulative kWh
• Power: 5V USB (adapter included)
• Hub required: Any Zigbee 3.0 hub (sold separately)

Important: The CT clamp clips around the cable without breaking the circuit — this is a monitoring device, not a switch. Installation is straightforward but involves proximity to live mains cables; if in doubt, ask an electrician to clip it on.
