EVB202 data loger

Post by pancio »

Hi,

This is my first post on this subforum. I've EnverBridge EVB202 as devices which communicate between micro-inverters and envertecportal.com to collect data... but i don't like send anything to china cloud so I'm looking for other possibility to read data from PLCC... I disassembled EVB202 looking for some kind of serial interface like RS232 or RS485 but i found only diagnostic socket - probably JTAG for LCP microcontroller. Of course I tried to communicate with him by TTL serial but it doesn't work on any signal pin (TTL 3V3 logic). Probably I need to have special plug and converter for JTAG programmer in order to communicate. I drop this idea for a while...

I tried to listen TCP transmission on ethernet port, I dumped packages and analysed them in Wireshark. EVB202 got IP from DHCP serwer and start communicate with www.envertecportal.com by sending owm ID. Next, EVB sending many shortly packages just only like heart bit - probably waiting for data from micro-inverters (PLCC). And finally one bigger (982 bytes of data + headers) package is sending to cloud, it contains all ours micro-inverter IDs (MIs) and some data (probably measurement variables). The question is how to guess/calculate which one is e.g power, temp etc. I need to add this data logger to my Home Assistant...

I suppose that is possible to decode data, and using own DNS cheat EVB202 and read data directly from device avoiding china cloud...

If anybody is interesting in topic, please let me know.

pancio

The gaps between micro-inverters are probably that they aren't ready or on installed on other phase...

Edit 1.
Based on easy12's 4th post (https://forum.fhem.de/index.php/topic,61867.4.html) I tried to decode data. I found 4 kind of packages witch data:

1. sending by EVB short packet (contains only valid data for one MI,
2. ACK for packet above (contains some data - probably timestamp)
3. sending by EVB long packet which conains data from all MIs
4. ACK for packet above (very short)

Code: Select all

AC/64
FREQ/265
TEMP/256
PWR_TOT/8192
PWR/64
DC/512
