I am using modbus2tcp in home assistant to get data from solar inverter as well.
Would love it if this could work.

If it is modbus then the length field is a bit odd. This should be two bytes and it seems only the first byte is the length with the value of 0x53 in the second half.
The type 1/2 fields before the data would be a unit identifier and function code if it was modbus. This might make sense if using the harvi to communicate between devices. I'm tempted to buy the ethernet adapter for the zappi and have a go. If I can intercept and spoof spare energy going out to the grid then I could finally control the damn thing.

I don't have the knowledge needed for this, bu I think this is the only way to save the product. With current cloud-only approach it is really bad and I would love any progress in this field.

Update:
Myenergi has finally confirmed that they are planning to monetize their API and that local one is not coming, as it, obviously, conflicts with the monetizing part:

While I am already reconsidering my hardware options, I would still consider a reversed ethernet control. Any info on that?
Just note that I don't care about server side, I want to interface with the v2.1 zappi directly. As for cloud, I'd like to cut off internet access altogether.

@ajaxharg - you could spoof this by sending a signal of your choice in place of the grid CT.
I'm also really interested in intercepting the comms locally though - I need to brush up on this stuff, but it's on the do list.
