# NOTE: the inverter PROTOCOL (PI30 / SMG-Modbus / Voltronic / ...) is chosen by the Home
# Assistant integration at RUNTIME — it is NOT configured here. This file only sets the
# platform and the physical serial LINK (pins, transceiver, baud). The SAME firmware/config
# works for every protocol; for a different inverter you change wiring/baud, not a 'protocol'.

# BK72xx (Beken, e.g. BK7231N) board via ESPHome LibreTiny — virtual eybond
# collector bridge for a PI30/Voltronic inverter. Same component as the ESP8266/
# ESP32 builds; only the platform block differs.
#
# Pins: BK72xx software serial is chip-dependent in LibreTiny, so put the inverter
# UART on a HARDWARE UART. Adjust tx_pin/rx_pin to your board's free hardware UART
# (the logger/flash UART must stay separate). See LibreTiny's board pinout.
