  9. thanks for the quick reply @coulomb Do you also have problems with it hanging or is it only me? do you have a simple program for rs232 comms -- send qpigs and wait for answer ? @ nikkitto I use your program to read I cant see you hidraw -- do i have to login to that site to see it ( hibrido test)? thanks so far
  10. Hi All Sorry if this is not the right topic but please advise Complete new guy here needs some help with MECER 5kw comms I have it hooked up to Raspberry pi -- USB and am able to read QPIGS etc the communication is very erratic with the inverter it hang while waiting for QPIGS to send the 110 bytes It works most of the time but hangs after a period Is there another communication channel --Rs232 maybe I have even got a separate python program running the QPIGS and QMOD writing that to file and the web page reading the file, but it still hangs so I cant log consistent Data or display it on my page updated every few seconds Is there a trick to this some of you guys seem to have solved this Also is it normal for the inverter to go to grid when the solar power in is Zero even if it has not reached the setting bin program 12
