Apr 27, 2023$35 SONOFF POW ring smart power meter (POWCT) safely supports up to 100A - CNX Software
Oct 16, 2024SONOFF POW Ring smart power meter is the first CT clamp-based WiFi power meter from ITEAD. It is designed for installation in an electric cabinet to measure whole-house power consumption with up to 100A current.
The power meter relies on an ESP32 microcontroller for control and wireless connectivity with a range of up to 130 meters thanks to an external high-gain antenna. It is supported by the usual eWelink mobile app that also enables integration with Google Home, Amazon Alexa, and IFTTT services, and ITEAD also mentions integration with the Home Assistant open-source framework.
SONOFF POW Ring (POWCT) specifications:
The SONOFF POWCT smart power meter ships with a 1-meter-long CT clamp, a WiFi antenna with a 30cm cable, a silicon seal ring, two screws, a mounting base, and a quick guide which you can also find along with a more detailed user manual on the SONOFF website.
Once the SONOFF POW Ring is connected to the eWelink app, you can check real-time, daily, monthly, and yearly power consumption in the Android/iOS mobile app, and also set timers, power consumption goals, configure voice control (Google Assistant and Amazon Alexa), Home Assistant, and automations through IFTTT.
ITEAD is selling the SONOFF Pow Ring smart power meter for just $34.90 on their online store, and as usual, you can also use the CNXSOFTSONOFF coupon to get a 10% discount on the device or any other item from the ITEAD shop. It’s not the first CT clamp smart power meter we’ve covered this year, but others are more expensive as they support more than one CT clamp to monitor multiple appliances. This includes the ESPHome-compatible “Smart Powermeter” with 6CT clamps and the Emporia Vue Gen 2 energy monitor with 16 CT clamps and support for both single and triple-phase power.
