The retail price is normally around $250 and you could price match at Bunnings.
A good simple well-made smart lock, Bluetooth only but you can purchase a Wi-Fi bridge $99. I wouldn't bother with the bridge as the lock runs on AA batteries, really needs lithium like Eufe.
I have one and it's very simple to retrofit as it comes with all the hardware required.
