You need device with working ESPhome and RS-485 Transceivers.

Example configuration:

# Generic ESPHome configuration example:

safe_mode:
  num_attempts: 3

rtl87xx:
  board: generic-rtl8710bn-2mb-468k

# Enable logging
logger:
  level: DEBUG
  # baud_rate: 0 # You may have to disable logger via serial.

# Enable Home Assistant API
api:
  password: "insert password here"

ota:
  - platform: esphome
    password: "insert password here"

wifi:
  ssid: "insert ssid here"
  password: "insert password here"

  # Enable fallback hotspot (captive portal) in case wifi connection fails
  ap:
    ssid: "AC Fallback Hotspot"
    password: "insert password here"
