INA3221 - Power meter logger

This is a 3 channel power logger. It is based on the INA3221 and as firmware i am using ESPeasy with this plugin: https://github.com/letscontrolit/ESPEasy/pull/4011

Hardware:

- INA3221 module

- Wemos D1 mini

- OLED SSD136 (optional)

- SD card module (optional)

- Switch

ESPeasy makes it possible to send the measurments to the OLED and MQTT without programming. And then you will have pretty graphs like these using InfluxDB and Grafana :)
