BACnetUnconfirmedServiceChoice ::= ENUMERATED {
...
who-Am-I (13), 
you-Are (14)

The packet structures are:

Who-Am-I-Request ::= SEQUENCE {
 vendorID Unsigned, 
 modelName CharacterString, 
 serialNumber CharacterString
}

You-Are-Request ::= SEQUENCE {
 vendorID Unsigned, 
 modelName CharacterString, 
 serialNumber CharacterString
 deviceIdentifier BACnetObjectIdentifier  OPTIONAL,
 deviceMACAddress OctetString OPTIONAL 
}

These are so new, in PROTOCOL REVISION 22 (currently the latest) as Addendum 135-2016bz , approved by ASHRAE and by the American National Standards Institute on November 18, 2019 that there hasn't been time for the industry to decide whether to embrace or ignore these. In some niche scenarios, I expect adoption. And for completeness (because they cause the equivalent of a DHCP operation) they merit coverage.
