Kelley told me the sensor doesn't currently tie into any type of Wi-Fi valve that could shut off the water supply, but being aware of a leak should give you an opportunity to act to prevent significant water damage.
The MyDlink Wi-Fi Siren (model DCH-S220, $50) is the last new product in D-Link's Connected Home Platform. A siren is an important component to have in any security system, but it's doubly important in one like this that isn't monitored by a central office. If it's loud enough, a siren could scare a burglar away, because the last thing they want is attention.
The DCH-S220 can be triggered by other D-Link devices, such as the motion and open/close sensors, and it can interact with other devices, such as the Wi-Fi Smart Plug. It can also send push notifications of its own. It uses Wi-Fi, so it must be plugged into an AC outlet.
D-Link expects to ship its Connected Home Hub and all of the sensors discussed in this story in the second quarter of 2015. We'll review them as soon as D-Link can provide evaluation samples.
