I have the inverter without wifi module so this project is perfect for me. Thanks for making it possible.

I have some issues. First I can't figure out witch of these wires of my inverter going to the "TTL to RS485" board. Screen Shot 2020-12-26 at 15 29 14

Second How should the LEDs on the TTL board blinks? My RX is steady and my TX flashes for every 10 seconds I think

Last: Which pins are the right ones on the NodeMCU boards? The label on the boards says D1 and D2 but I'm not sure. NodeMCU-V3-2

Sorry for all the noob questions but I don't know where else to go. Best regards Soren

I think you need pin 6 & 8 (RS485A). On the NodeMCU just follow the labeling on the board itself, so the pins top right that have the GPIO5 & GPIO4 labels in your image.

What issue do you exactly have, do you have a debuglog?

I moved to GoodWeUSB logger instead after a million failed attempts. It works for me now.

Best regards
