Hi all:

Again... no idea of how achieve this, so I need your help.

We have a small house near the beach, and we have installed an isolated solar system a few days ago.

This is the inverter we have:

It has:
- Integrated Bluetooth interface with Android App.
- Reserved communication port (RS-485, CAN-BUS or RS-232) for BMS.

It has a PC software, and you can connect throught RS-232 or USB to the PC. Installing a PC to see the data with teamviewer is not the best solution.
I have a ESP8266, from this thread, I think first think thing I'd need to start playing is a RS232->TTL converter? (the linked one, for example?)
It would be the ESP8266 enough to start watching the serial data and try to extract the values I'd like to see?

Thanks in advance.

Probably it works by polling. If you own a RS232 tester you could inspect protocol. I did for many years. Since 1975... A tester can be built around two RS232 ports. Good luck. Ask to the company for more info. Sometimes they help...
