Hi, Have had my open energy mon setup for years, but recently I have gone a bit further and realised my solar inverter is a Modbus slave. I have managed to write a program to extract the data and am ready to post it to my emoncms.org account.
When posting the current power during the day everything is fine but at night when the inverter is off/ not responding and producing 0 power how often do I need to s post a zero value to emoncms. Is once enough and then when it starts generating in the morning I send the current values or do I need to send 0 at intervals during the night .
Thanks Paul
