Greetings.
after a couple of days of tinkering I found a partial solution, at least as far as the app is concerned. the problem was the wrong "PN" number... using the wifi ?ssid it worked... I don't know why the number on the label was wrong.
the problem of the serial remains (which is the one I need to interface the inverter with home automation (openhab).
the problem that arises is that the watchpower software does not detect the inverter... by querying with a terminal (at 2400 8n1 ) the inverter replies "NAKss" and this is normal given that the crc has not been inserted, but the test I needed to see if the 232 was operational...
I have no idea of the type of protocol used by this inverter if it is the same as that of a VM III that I already have running (commands with the "Q" qpiri, qmod, etc.
Does anyone have any idea what I can do to try something?
Thank you
Joseph
