Just updating the thread for locks.
Most people using SmartThings get Z wave locks, in part because then there’s no issue with Wi-Fi interference which allows you to boost Wi-Fi signal near the front door for cameras or Wi-Fi video doorbells without running into a problem. But most of the big lock companies also makes zigbee versions of their smart locks if you want one. As of this writing, February 2017, none of the Bluetooth locks are compatible with SmartThings.
There are two main kind of zwave smart locks for homes: keypad locks, which replace the existing deadbolt and have a keypad on the outside of the door where you can enter a code, and retrofit locks, where the exterior piece is the same as always, and there’s a piece that goes on the inside of the door and fits physically over the existing turn bolt so that it can be turned.
Keypad lock on the exterior side. It replaces the existing deadbolt
Keypad lock on the interior side
Interior with retrofit lock. It fits over the existing turnbolt. The exterior will look the same as always.
Both can be opened automatically or from your phone. The big difference is that the keypad lock enables someone, such as a child who lives in the home, to open the lock from the outside without needing either a phone or a key. But for those who live in apartments or subdivisions which require that all exterior door locks look the same, the retrofits are a good option. Also, some people just prefer them aesthetically.
You can get a keypad lock which just replaces the deadbolt, or one that has a built-in lever handle as well.
If you live in the UK, there are also some keypad locks that are much thinner and designed to fit European doors.
keypad lock features
There’s an FAQ for Z wave/zigbee keypad locks that covers different brand features , so I won’t repeat all that information here. Just follow this link:
2017 did see the release of the August pro, which is the only lock which can be used with both SmartThings and HomeKit, so if you’re looking for that particular combination, that’s another one to consider. It’s a retrofit lock so that there is a piece that fits over your existing deadbolt turn the key on the interior, and the exterior looks the same as it always did. No keypad unless you buy a separate accessory device. So it will be good for some use cases, but not others.
