// *_LIST macros will be generated in defines.h if at least one sensor from each platform is used.
// These lists will look like this:
// #define OPENTHERM_BINARY_SENSOR_LIST(F, sep) F(sensor_1) sep F(sensor_2)
// These lists will be used in hub.h to define sensor fields (passing macros like OPENTHERM_DECLARE_SENSOR as F)
// and setters (passing macros like OPENTHERM_SET_SENSOR as F) (see below)
// In order for things not to break, we define empty lists here in case some platforms are not used in config.

// *_MESSAGE_HANDLERS are generated in defines.h and look like this:
// OPENTHERM_NUMBER_MESSAGE_HANDLERS(MESSAGE, ENTITY, entity_sep, postscript, msg_sep) MESSAGE(COOLING_CONTROL)
// ENTITY(cooling_control_number, f88) postscript msg_sep They contain placeholders for message part and entities parts,
// since one message can contain multiple entities. MESSAGE part is substituted with OPENTHERM_MESSAGE_WRITE_MESSAGE,
// OPENTHERM_MESSAGE_READ_MESSAGE or OPENTHERM_MESSAGE_RESPONSE_MESSAGE. ENTITY part is substituted with
// OPENTHERM_MESSAGE_WRITE_ENTITY or OPENTHERM_MESSAGE_RESPONSE_ENTITY. OPENTHERM_IGNORE is used for sensor read
// requests since no data needs to be sent or processed, just the data id.

// In order for things not to break, we define empty lists here in case some platforms are not used in config.
