Thanks, I made a DIY cable, but lately I found this https://www.amazon.com/dp/B07JGRJR4V and I tested it and found working with Renogy Wanderer. Just that I had to use device id as 255, ie:
RenogyRover('/dev/tty.usbserial-D309XXXX', 255)

+1 please give more detail how you connected Pi to the the controller.
Appreciate

Based on this post on diysolarforum.com, following PINs are used:
- 1 - TX
- 2 - RX
- 3 - GND
I did not use USB, but instead used Pi's GPIO with max3232 RS232 to TTL converter.
Oh, and I connected to Renogy Wanderer.

just a clarification for anyone else following along, there are a few Renogy Rj12 TO DB9 connection images out there that are wrong. as you look at the RJ12 Plug and see the gold pins the numbering starts from left to right 1 - 6, pin 1 is the Renogy's TX pin, pin2 Is the Renogy's RX pin, pin 3 is ground. you should get about 5.6 V when you test TX and GND
Renogy TX 1 ==> DB9 Pin 2 RX
Renogy RX 2 ==> DB9 Pin3 TX
Renogy GND 3 ==> DB9 Pin 5 GND

Thanks for all the pinouts and information, those chips look great! If anybody needs a schematic rep i think i've compiled @jova1971 and @sashkab 's input, ill report back when i get the prototype and confirm :)

Just wanted to share a working pre-made cable you can buy on Amazon.. tested it out and worked great!
