Product Description
Zemismart 120A Zigbee WiFi Din-rail Energy Meter 3 Phase Power Monitor Work with Tuya Withdrawable Split-core CTs 120V 240V
Note Before Order:
- The default data reporting time for Zigbee Version SDM01 is 600 seconds, and for WiFi Version is 300 seconds.
- This product cannot be directly connected to ZHA, and can only be paired with Home Assistant through the Zigbee2mqtt dongle.
- It can only measure the total energy and cannot measure the energy of each phase separately.
- The bidirectional monitoring function can only be viewed on Home Assistant and cannot be displayed on the Tuya app.
- This 3-phase energy meter has two versions, WiFi and Zigbee. Please check carefully which version you need before placing an order.
Product Description:
*SDM01 smart energy monitor is a monitoring device that consists of a 18mm-width (1MW) monitor installed at DIN rail and three split-core current transformers (CTs). lt can work like a professional 3-phase energy meter that measuresvarious types ot electrical data - such as voltage, current, power and energy- at real-time.
Feature:
- WiFi Version: No need hub or gateway, works with WiFi 2.4Gh, Tuya App/ Smart Life App control.
- Zigbee Version: support Tuya Zigbee Hub control/Home Assistant control via Zigbee2mqtt dongle( For details, please refer to this link: //www.home-assistant.io/integrations/tuya/)
- Electrical Measurement: High-Accuracy metering (class 1)/Real-time Measurement/Bi-directional Monitoring/Three Phase & Individual Phase Monitoring/Different CT size up to 120A Meaurement.
- Bi-directional Measurement: Bi-directional measurement of power and energy flow. (NOTE: This feature only allows the Zigbee version of 3-phase meter to view specific values and charts on Home Assistant through Zigbee2mqtt, which is not supported on the Tuya app.)
- Unbalanced-load Alarm: when the load is unbalanced, it is necessary to check the electrical box in time to prevent short circuit and protect the safety of household electricity.
- Easy installation: Monitoring module reguiring only 1MW at DIN rail and associating with compact split-core CTs/Withdrawable connector for CT connection/Withdrawable connector for voltage take-offs connection.
- Safety: Abnormal usage Alarm/ Over-consumption, Overload Alarm, Over/Under voltage Alarm.
