Inverter USB hidraw Interface #29

I wonder if somebody was able connecting the ESP8266 to the USB interface of the inverter. My PIP2424MSE doesn´t provide a RS232 port, even not internal. On Linux, the inverter port is discovered as a HID device.

Connecting a USB cable from a WEMOS D1 to the inverter didn´t work, at least no values are shown (only 0) on the Solar2MQTT.

Not sure if the onboard ESP-UART0 -> CH340 -> USB cable -> InverterPort could work at all?

Hey, i am not sure if a complete usb interface including a driver is needed for that but i would think so.

i think the inverter is doing something like this on the usb port: https://www.pjrc.com/teensy/rawhid.html
