Functions
uint8_t	esphome::home_io_control::decode_uart_probe (const uint8_t *raw, uint8_t raw_len, uint8_t bit_offset, uint8_t *decoded, uint8_t decoded_max_len)
	Decode a raw UART‑encoded bitstream into bytes.
bool	esphome::home_io_control::is_known_io_command (uint8_t cmd)
	This list missing CMD_GET_GENERAL_INFO3_RESP (0x59) is exactly what turned a real Q2 probe reply into a false "no reply" timeout on real hardware (2026-08-16); the same audit also found CMD_IDENTIFY and CMD_WRITE_PRIVATE/CMD_WRITE_PRIVATE_ACK missing, unrelated to that probe but affecting the already-shipped identify_device() action (and climate writes) on SX1262/LR1121.
static std::pair< uint8_t, uint8_t >	esphome::home_io_control::find_crc_valid_frame (const uint8_t *decoded, uint8_t decoded_len)
	Try to find a CRC-valid IO-Homecontrol frame within a decoded UART byte stream.
UartProbeResult	esphome::home_io_control::find_uart_probe (const uint8_t *raw, uint8_t raw_len)
	Search raw RX buffer for the best CRC-validated IO-Homecontrol frame.
uint8_t	esphome::home_io_control::soft_phy_raw_bytes_for_frame (uint8_t frame_len)
	Raw on-air bytes needed to carry a whole frame: frame_len protocol bytes plus the two trailing CRC bytes, each UART-packed into a 10-bit cell.
uint8_t	esphome::home_io_control::soft_phy_peek_frame_length (const uint8_t *raw, uint8_t raw_len)
	Recover a frame's total length from the very first UART cell of a reception.
uint8_t	esphome::home_io_control::uart_encode_packet (const uint8_t *data, uint8_t len, uint8_t *encoded, uint8_t encoded_max_len)
	UART-encode a buffer of bytes (start bit 0, 8 data bits LSB-first, stop bit 1).

Variables
static const uint8_t	esphome::home_io_control::UART_PROBE_MAX_BIT_OFFSET = 10
	Maximum bit offset to search for valid UART decode start position.
