Bosch EVSE Network Connection

Got my Bosch EVSE installed and inspected so I decided it was time to go check out that RJ45 port in with the power connections. We know it's actually a Delta EVSE http://www.deltaww.com/Products/CategoryListT1.aspx?CID=0806&PID=289&hl=en-US&Name=Delta%20EV%20AC%20Charger and the MAC address printed on the side belongs to Delta.

SAFETY WARNING - the port is very close to the power connections, switch it off at the breaker before you plug and unplug it!

On powering on the EVSE it gets an IP address via DHCP but then doesn't output anything. I scanned it with nmap and it only has a web server on port 80. That web server only seems to have a default webpage showing it is an STMicro STM32F4 http://www.st.com/web/en/catalog/mmc/FM141/SC1169/SS1577?sc=stm32f4 running lwIP http://savannah.nongnu.org/projects/lwip/

I was hoping for metering of the power used based on the Delta product page and maybe wifi access to that to avoid the need for running a cable (after everything was setup), but it looks like it is not to be. I wonder if the hardware is all in there but they just put a base software load on it for Bosch.

I bought a used Bosch 30 amp EVSE and was considering modding it with a cheap CT with LCD readout (PZEM-006), so that I can view the energy consumption at the wall. I opened up the EVSE since the warranty was void the minute I bought it used. The mainboard is divided roughly into 4 sections for J1772 management, DC power, network, and what I think is signal processing. I could make out an ARM trademarked chip and a LAN filter on the network section, but no identifiable radio chip. There were also a couple of multi-pin connectors that didn't connect to anything, so wifi may be on an add-on daughter board like the "Stop" button and the status light. The processing also had a smaller ARM trademarked chip, and a CT loop and a 240V AC relay like the PZEM-006.

I'm pretty clueless about electronics, but my guess is that all the components needed for basic data processing and transmission is already there. Delta probably flashes each board to brand, model, destination, etc. Considering that there is no how-to instructions to custom flash the hardware, I think it will be lesser of a hassle (for me) to dremel a hole on the case for the PZEM-006.
