ethernet active mode: failed to parse message

[fredericve]

Hi,

I have an SE5000 inverter and would like to get some data about the optimizers in my setup.

I have my local dns servers pointing prod.solaredge.com and xprod.solaredge.com to a local server on my network and am running semonitor there while listening on ports 80, 22221 and 22222.

I first dumped the encryption key using sekey.py and passing that to semonitor.py now. So then I launch semonitor and getting this output:

./semonitor.py -t n -vvv -o output.json -k inverter.key -p 80,22221,22222

Anybody have a clue what I'm doing wrong?

Ah, I read in the updated readme that essentially the ethernet method no longer works, only RS485 will. But does RS485 include any data about the optimizers? That's really what I was looking for.

It should, if you configure it to use the SolarEdge protocol.
