Overview
The SONOFF POW Ring is a Wi-Fi power meter that packs its switching, wireless and current-sensing parts into one compact unit. It shows how much electricity a circuit is using, so you can find out which appliances or rooms are driving your bills.
It works for home and small business use, and it also tracks solar generation and consumption, which makes it useful for households with solar panels.
