Get Power data on MQTT with Sonoff Pow or Pow r2

[pelinquin]

Hello Martin,

I'm new with esp_mqtt. Thanks to your framework and scripts...I succeed in few hours to toggle the relay on a Sonoff Pow r2 with one of your script example. However, I need to read energy consumption data for my application, using MQTT.
Should I have to configure the UART ? How ?
Do you have an example that could help me ?...using Sonoff Pow would be great.
The Sonoff Pow r2 use the CSE7766. That's all I know.
Best regards

Laurent from Paris
