Article description:

WiFi Smart Power Meter with CT clamp and antenna

Already flashed with the latest Tasmota firmware.

Split-Core Current Transformer Clamp - Transformer current detection up to 100 A. No physical contact with live wires, eliminating the risk of electric shock. You can simply release or close the latches on the side of the sensor to open and close the CT sensor.

Energy Monitor - Install the device in your home's electrical circuit panel to monitor the power consumption of household appliances or rooms.

6-Month Historical Data Retention - Automatically saves your power usage data when you remove devices or there is a power outage. The data can be stored for up to 6 months and exported to a file for viewing.

Contactor Control Support - The POWCT has a floating relay with a rated current output of 2A, which is used with a contactor to realize load control.

Safe and Reliable - Undergoes various rigorous tests, including lightning and surge tests, short circuit tests, drop tests, salt spray tests, extremely harsh environment tests, etc. Products you can trust 100%.

Variant with Tasmota Firmware - The SONOFF POWCT can be easily integrated with Tasmota and MQTT into smart home systems, such as Home Assistant, ioBroker and many others that support an MQTT interface.

Power consumption meter 100A WiFi POW Ring SONOFF POWCT (current probe) - The SONOFF POWCT is an innovative power consumption meter that combines modern technology with safety and convenience. It is equipped with a current probe that allows a detection range of up to 100A, allowing precise monitoring of household electricity consumption without physical contact with live wires, thus eliminating the risk of electric shock. The accompanying mobile app offers an intuitive interface that allows you to check your energy consumption in real time, receive detailed daily, monthly and annual reports, and export data to a file to better understand your habits and optimize costs. This makes the SONOFF POWCT the ideal solution for safe and efficient energy management in your home.

Precise monitoring of energy consumption - The SONOFF POWCT allows you to easily monitor the power consumption of various devices or entire rooms in your home. By installing the meter in your electrical box, you can keep an eye on your energy consumption in real time and optimize your costs. Thanks to the historical data storage function, the device automatically saves consumption data for up to 6 months, so you can export and analyze it at any time. This is an ideal tool for those who want to better manage their energy consumption and reduce their electricity bills.

Safe and Reliable Construction - The POWCT was designed with safety and reliability in mind. It has passed a series of rigorous tests, including lightning, over-voltage, short circuit, drop tests and operation in extreme environmental conditions. The robust PC plastic housing and the ability to operate in a wide temperature range (-40°C to 50°C) and humidity from 5% to 95% RH (non-condensing) ensure long-term reliability and safe use.

Additional features and connectivity - The SONOFF POWCT supports the function of remote control of contactors via a built-in relay with a current output of 2A, which enables load control in a domestic electrical system. IEEE 802.11 b/g/n Wi-Fi connectivity at 2.4 GHz and SMA antenna port ensure a stable connection and the ability to remotely monitor and control via a mobile app. In addition, the meter works with Google Home, IFTTT and Alexa, meaning you can successfully integrate it into your smart home and operate it with simple commands. The device is easy to install and configure, making it a perfect solution for home use.

Advanced features with Tasmota - The SONOFF POWCT can be easily flashed with Tasmota firmware to expand its functionality and optimize integration into smart home systems. Tasmota enables the use of MQTT, so you can seamlessly integrate the device with platforms such as Home Assistant, ioBroker and many others. In addition, the SONOFF POWCT is Matter compatible, ensuring even broader interoperability with other smart home devices. A key advantage of Tasmota is its cloud-free use, which means no data is sent to external servers. This guarantees that your information remains private and does not fall into the hands of third parties. With Tasmota you have control over firmware updates and can customize the device to your specific needs.
