Use this to retrive data packed captured by listen() function.
Data packet is ready when has_message() function returns true. This function can be called multiple times until stop() is called.

void esphome::opentherm::OpenTherm::listen | ( | ) |
Start listening for Opentherm data packet comming from line connected to given pin.
If data packet is received then has_message() function returns true and data packet can be retrieved by calling get_message() function. If timeout > 0 then this function waits for incomming data package for timeout millis and if no data packet is recevived, error state is indicated by is_error() function. If either data packet is received or timeout is reached listening is stopped.

void esphome::opentherm::OpenTherm::send | ( | OpenthermData & | data | ) |
Immediately send out Opentherm data packet to line connected on given pin.
Completed data transfer is indicated by is_sent() function. Error state is indicated by is_error() function.

void esphome::opentherm::OpenTherm::stop | ( | ) |
Stops listening for data packet or sending out data packet and resets internal state of this class.
Stops all timers and unattaches all interrupts.
