Nar the Yale / Lockwood deadlatch can be locked from the inside with a physical key. However the outside does not have a keyway, so entry is by an NFC tag, pin or via the app or home assistant.
Might? Be what your chasing. Think Bunnings stock the black one while JB have the silver.
Comes stock with a BT module, but you can purchase a Zigbee module for an exorbitant $70+
Darn, thanks anyway tho!
