The Nexia kit includes a ZWave base station -- a requirement to interface to the internet. I chose the Schlage deadbolt kit because it was less expensive than the door handle. However, the deadbolt provides less functionality -- a person must turn the deadbolt within 30 seconds of the unlock command in order to open it. If you need better functionality, the door handle can be locked or unlocked at will, without a human on site.
We've had mixed experience with ZWave door latches and deadbolts. We have two deadbolts and four latches, and I think we're probably not going to purchase any more ZWave devices nor Schlage electrical locks. Batteries run out every 6 months, or sooner in one case. Our identical devices were indistinguishable from one another at set-up, and this required a significant amount of extra labor to sort out which device was being mapped to which label. Our Vera II ZWave controller is sufficiently unintuitive that it's a brand new learning experience every time we touch it, considering that we touch it only at annual intervals intervals or so. Finally, our devices must be fully disassembled to change batteries, which is nearly the same level of effort as reinstalling the door latch each time the batteries die. Recently this resulted in a broken wire, taking one of the devices out of service ($250 original cost, lost to changing batteries). The device routes a wire to the two pieces, one on each side of the door, and the wire is stressed each time the batteries are changed.
Still, the customer might be satisfied at this price point and functionality.
