Use on mirror port (span port)

[Bård Dahlmo-Lerbæk]

I'm trying to figure out Grott can be set up get data from a mirror port that mirrors all traffic to and from the inverter. My plan is to have Grott run on its own interface (eth1 for example) and configure the switch to mirror all traffic to and from the ShineLan box to that port.
eth1 will need to be set up in promisq mode and the traffic will have the mac addresses of the default gw and the ShineLan box.
Is this something that can work?

I am not sure what you want to do. Seems a little bit complicated to me. Why not using the "normal" proxy mode of grott (listing at port 5279 and sending the data unchanged to the growatt server)?

The goal is to have as few dependencies as possible so that connection to the growatt server works even if the grott service fails.
