DONT WORRY, found link in your blog :)

Awesome! Have been looking for example like this! Thank you so much for posting.

Could you please tell me what the model of your rs232<->rs485 converter with automatic flow direction control unit is please?

Many thanks! Paul

Hi At low bitrates (up to 9600baud) shouldn't the ESP8266 alone be enough to read an RS485 without a converter? https://github.com/plieningerweb/esp8266-software-uart https://github.com/peninquen/Modbus-Energy-Monitor-Arduino
