I have a Schneider EM6400 meter whose data I need to send to a web-service.
I dont know much about electronics so here it is-
How do I do it? My idea is to use an ESP8266.
But from what I know, the meter sends data from RS485. Hence direct connection is not possible.
Can I use RS485 to TTL bi-directional Converter?
Also, I think the output can be obtained from USB. So, Can I connect that USB to USB 2.0 to TTL UART Serial Converter or FT232RL 3.3V 5V FTDI USB to TTL Converter?
NOTE: I know the ESP programing part. Just need to know about the conversion.
