I am trying to get a RPi Z to talk to my ME3000SP unit but not getting anywhere. Do you need to have the inverter in Passive mode for 485 communications to work correctly? Looking to control unit so that I can take advantage of negative electricity prices. Currently have other systems to switch over with pricing but battery inverter currently isn't controlled remotely. Any assistance is greatly appreciated.

Just got hold of a new cable as the previous only the connector didn't look perfect (could have not been connecting in the port correctly) so anyway, after making up a new cable and buzzing through the cables from end (as done with previous cable), I am still not getting anywhere. I connected as you suggest using 1200bps 8N1 but got no reply for either enter or any other command I have sent. I know this COM port works as I use it all the time and buzzing out the cable means the cable is working correctly. What else can I try? (see settings below).

Click "Intro"? I am missing something with this mystery button that I don't have? Might need the basics on here as clearly I something is wrong? Cable has been buzzzed out and works fine but never had a reply from batttery. I followed instructions from Plyontech youtube video regarding broadcasting battery information over JSON but that didn't work so now trying directly with serial cable directly to laptop but still cannot get any comms (which would explain why the first attempt didn't get comms either). Any assistance is greatly appreciated. Screenshots would be appreciated... for example, do you type "Data: 7E 32 30 30 31 34 36 38 32 43 30 30 34 38 35 32 30 46 43 43 33 0D" when sending that information or is there another mode to switch to within Termite? I work with RS232 all the time at work and generally it works or it doesn't so a little confused about why it is not working? to

I downloaded termite but I'm not getting anywhere. I've created a cable with the correct pins (2, 3 & 5 for RS232) communications and have attempted to send the commands but just getting nothing in return. The instructions are pretty clear so no sure what I am doing wrong? Any guidance is appreciated.
