Variables
static constexpr uint32_t	esphome::home_io_control::FREQ_CH1 = 868250000
	The protocol uses 3 frequency channels in the 868 MHz ISM band.
static constexpr uint32_t	esphome::home_io_control::FREQ_CH2 = 868950000
	Channel 2: 868.95 MHz (1W and 2W, TX channel).
static constexpr uint32_t	esphome::home_io_control::FREQ_CH3 = 869850000
	Channel 3: 869.85 MHz (2W only).
static constexpr uint16_t	esphome::home_io_control::LONG_PREAMBLE = 1024
	Preamble is a sequence of 0xAA bytes that precedes every frame.
static constexpr uint16_t	esphome::home_io_control::SHORT_PREAMBLE = 8
	8 bytes for response/continuation frames
static constexpr int32_t	esphome::home_io_control::HOP_TIME_US = 2700
	Timing constants for frequency hopping and response waiting.
static constexpr int32_t	esphome::home_io_control::RESPONSE_CHANNEL_WAIT_MS = 50
	Per-channel dwell while waiting for an exchange response.
static constexpr int32_t	esphome::home_io_control::RESPONSE_WAIT_MS = 500
	Wait for response to non-start frame.
static constexpr int32_t	esphome::home_io_control::RESPONSE_START_WAIT_MS = 1000
	Wait for a response to a start frame — the first frame of an exchange, and the one a sleeping device has just been woken by.
static constexpr int32_t	esphome::home_io_control::RESPONSE_AUTH_WAIT_MS
	Wait for final response after challenge response.
static constexpr int32_t	esphome::home_io_control::EXCHANGE_RETRY_DELAY_MS = 250
	Gap between retries within one HA command.
static constexpr uint8_t	esphome::home_io_control::EXCHANGE_RETRY_COUNT = 3
	Attempts per command before reporting failure.
static constexpr int16_t	esphome::home_io_control::LBT_RSSI_THRESHOLD_DBM = -90
	Listen-before-talk (LBT) parameters for ETSI EN 300 220 compliance.
static constexpr uint8_t	esphome::home_io_control::LBT_MAX_RETRIES = 5
	Max carrier-sense attempts before TX anyway.
static constexpr uint8_t	esphome::home_io_control::LBT_RETRY_DELAY_MS = 5
	Backoff between LBT checks (≥ 5ms per ETSI).
static constexpr uint16_t	esphome::home_io_control::PAIRING_DISCOVERY_WAIT_MS = 2000
	Canonical defaults for the chip-neutral runtime-tunable pairing/discovery parameters.
static constexpr uint16_t	esphome::home_io_control::PAIRING_DISCOVERY_INITIAL_DWELL_MS = 300
	Dwell on CH2 before discovery hopping begins.
static constexpr uint8_t	esphome::home_io_control::PAIRING_KEY_EXCHANGE_RETRIES = 3
	Retries for the authenticated key-exchange phase.
