Electrical meter IEC62056 (rs385) reading using esphome?

ESPHome

Hi, i’m trying to read electrical meter using esphome so for now i connected wemos D1 mini with reading head that should just convert serial from the optical interface to the seral rx tx, but i do not see any traffic on the serial port

this is my config just for test:

esphomeyaml:
  name: test
  platform: ESP8266
  board: d1_mini

wifi:
  ssid: nyancat
  password: isalsolong
  use_address: 192.168.50.45

api:

ota:

captive_portal:

web_server:
  version: 2

logger:
  baud_rate: 0
  level: DEBUG

uart:
  tx_pin: 1
  rx_pin: 3
  baud_rate: 9600
  debug:

meter should use rs485 / IEC62056 for communication

from my past, very limited experience, rs485 devices broadcast their status, do i need to wake up the meter by sending it something first?

I tried calling service provider if maybe the interface is disabled on the meter, but the guy on the line did not know anything. Kinda expected.

Hi,
I’m going to realize the same interface in the same way.
Have you found the way to achieve this? Can you share it?

Many thanx
