Its home insurance product is intended to lean on sensor tech and wireless connectivity to reduce home-related risks — like fire and water damage, break-ins and burglary — by having customers install a range of largely third-party internet-connected sensors inside their home, included in the price of the insurance product. So it’s a smart home via the insured backdoor, as it were. Customers also get an app to manage the various sensors so they can monitor and even control some of the connected components, which can include motion sensors, cameras and smoke detectors. The Neos app is also designed to alert users to potentially problematic events — like the front door being left open or water starting to leak under their kitchen sink — the associated risk of which a little timely intervention might well mitigate.
