SONOFF POW Elite is an ESP32-powered smart power meter switch that can handle up to 20A max load to monitor the power consumption of all appliances in a whole room.
The data can be visualized in real-time on the built-in LCD or via the eWelink app, up to six-month of hourly power consumption history can be saved, and the system can also be integrated with third-party solutions such as a Home Assistant, IFTTT, and Alexa Energy dashboard.

The eWelink app for iOS or Android is used not only to monitor the power consumption but since the device is also a switch, you can set schedules and scenes (e.g. turn off when power consumption > 20 kWh), and configure Amazon Alexa or Google Home to control the switch with voice commands. There’s also a LAN function so you’d even need access to the Internet to control the switch after the initial setup.
The power consumption data can also be exported to Excel or another spreadsheet for further processing. More details may be found in the documentation. SONOFF POW Elite is really new, and right now only the official eWelink app is supported, but there should also be support for the popular ESPHome and Tasmota open-source firmware given enough time.
The SONOFF POWR316D (16A) and POWR320D (20A) models are up for pre-order on ITEAD shop for $16.99 and $19.99 respectively with shipping scheduled to start on June 23, or less than one week from now.
