Yale Assure Keyed Digital Deadbolt YRD426NRSC is now on sale @ JB Hi-Fi for $263.
Previous OzB deals for $299+$50 cashback and $299.
This is the Bluetooth version with the key backup (I prefer this instead of having to use 9V battery backup). I bought mine about a month ago for $280 (OW price beat Bunnings). Reason for going with Yale was that it was straight replacement for existing Lockwood (owned and now rebranded by Yale) deadlock. It uses standard Australian key cylinder so it could be easily re-keyed to match other locks around the house (unlike Samsung).
Bluetooth function and Yale App are rubbish. Within a week I bought Z-Wave network module to replace Bluetooth one (unfortunately can't have both), and never looked back.
Lock is now integrated with Home Assistant and works great :)
Cheapest Z-Wave enabled lock I could find currently is $399 on sale. It is only $327 for Bluetooth Lock plus Network Module (Z-Wave or Zigbee) @ JB.
Price beat @ Bunnings or Officeworks to save even more :)
Great deal. Just wish I could find somewhere to buy the August module separately
