Three-phase bidirectional Zigbee energy meter 3.0 Tuya 80A
The three-phase energy meter (available under the names ZPC-OW-80A-EN, PC321-Z-TY, TS0601) is an advanced device for precise, bidirectional current measurement, ideal for photovoltaic systems. For proper operation, it requires a Zigbee 3.0 gateway compatible with the Tuya ecosystem. The module offers full control in the Tuya Smart app, and thanks to official support for Zigbee2MQTT, it integrates perfectly with the Home Assistant system.
Key features:
- Measurement bidirectional: precise monitoring of energy consumed and fed back into the grid (essential for PV installations).
- Connectivity Zigbee 3.0: stable and energy-efficient communication (requires a compatible Tuya gateway).
- Open ecosystem: seamless integration with Home Assistant via the project Zigbee2MQTT (TS0601 chip).
- Non-invasive installation: measurement performed using the included current transformers 80A without cutting wires.
- Advanced analytics: live data preview and extensive history of measurements stored in the app for 365 days.
Scenes and automations in a smart home
Thanks to precisely collected data, the meter provides an excellent basis for optimizing energy consumption. It allows for creating rules (e.g., automatically turning on a heat pump or heater when there is a large surplus from solar panels). You can use parameters separately for each phase to trigger scenes from the app:
- Grid supply voltage (less than, greater than, or equal to)
- Currently consumed or fed-back power
- Total energy consumed
- Total energy produced
- Power factor
