Python Plugin: SMA Inverters ModbusTCPIP

[doki]

Hello!

Plugin works with SMA Sunny Tripower inverter, 8 parameters are mapped:

• Solar Production

• DC Voltage

• Active Power AC

• Active Power DC

• DC Current

• Active Power L1

• Active Power L2

• Active Power L3

Added to my domoitcz setup, use for sunnyboy.
TCP and UDP modbus is activated on my SMA port 502.
Should I use device ID 3?

ID 3 is correct for SMA inverters.
Please send me number of registers and description.
for example solar production - 30529
PS test your connection using program: http://en.radzio.dxp.pl/modbus-master-simulator/
how to use is it explained on this page:

Hi doki,

Installed and working. Great work! I'm just wondering each parameter's meaning. I think Active Power AC is instant power generated and totalizes Active Power L1, L2 and L3 (one for each phase). But I'm not sure how to understand the rest of parameters (beside Solar Production that is total production since beginning of installation). In fact, I'd like to know daily, monthly and year production, and instant compsumption from public network (information that I can see in weconnect tool).

Thanks for your great job and for your answer.
