Smart home technology and insurers

Insurers are partnering with smart-device makers because a few kinds of loss, mainly water and fire, are costly and often preventable. They give away or discount sensors, shutoff valves and fire detectors, sometimes add a premium credit, and in return get fewer large claims and, in some programs, data. As a homeowner you gain a device and an early warning. Whether you also give up privacy depends on the program, and the terms are worth reading before you pair anything.

For the list of credits by device and company, see security systems, smart devices and discounts. This guide covers the insurer's side of the arrangement and what it means for you.

Why insurers want connected homes

Insurers' interest is mostly in severity. A slow undetected leak or a failed supply line can turn a small repair into a full gutting, and the water often runs while no one is home. Amica says one in 60 of its policyholders has a non-weather water loss each year, with an average claim of more than $21,000 (Insurance Journal, Oct. 9, 2026). Chubb calls interior water leaks and burst pipes "a #1 source of property damage" (Chubb). Those are the insurers' own statements, but the broader industry data agree on direction: water damage and freezing is the second most frequent homeowners claim after wind and hail (water leak sensors and shutoff valves: discounts and value has the Triple-I figures).

A device that shortens the time between failure and shutoff cuts the biggest part of a water loss. The same logic applies to electrical fire sensors, smoke and heat detectors, and, to a lesser degree, burglar alarms.

How the programs are built

Specifics from published program pages:

• Nationwide offers a free or discounted water leak detector and electrical fire sensor from named vendors, says participation may earn a discount on the fire, theft and water parts of the premium, requires activation within 55 days of enrollment or the discount is removed, and says the program is not available in Alaska, Hawaii, Louisiana, New York or Oklahoma (and the page also lists Washington). On data, it says the information is available to the customer through the device app and that "the data collected will not be used to deny a claim." The page does not say whether data can affect underwriting or rates (Nationwide).
• Amica Mutual Insurance announced a no-cost Flume Smart Home Water Monitor with three years of service for policyholders in three states, and a discounted device elsewhere. Flume's claim of a 60% reduction in water damage claim frequency comes from the vendor and was not independently verified. The article contained no Amica statement on how policyholder water data is collected or shared (Insurance Journal).
• Chubb says clients may get a discount on recommended devices and may be eligible for a policy discount, and notes that devices outside its network are the policyholder's responsibility to buy, install and troubleshoot (Chubb).

Programs open and close, and a state-specific filing decides whether a credit exists where you live.

What the insurer gets

• Fewer and smaller claims, which is the point.
• A reason to keep you. A customer with an activated device and an app has a relationship beyond the annual renewal bill.
• Data, in some programs. What that data is differs. A leak sensor can report only alarm events; a whole-house flow monitor reports water use over time, which can imply when the house is occupied.
• Marketing and brand value. Free devices are a sign-on incentive in a competitive market, especially for insurtech companies; see insurtech home insurers: what they changed.

What you get, and what you risk

The upside is concrete. A sensor that alerts you to a leak under a sink in the first hours turns a possible full-room claim into a wiped floor and a towel. The claim you do not file also keeps your history clean (will a claim raise your homeowners premium?).

The risks are mostly about information and expectations.

1. Data use. State regulators are still weighing the benefits and harms of insurers' use of technology and consumer data, according to the NAIC, which says the privacy model law every state adopted for Gramm-Leach-Bliley compliance is outdated and is being redrafted (NAIC). A program may promise not to use data to deny a claim, as Nationwide does, and still leave open other uses, such as at renewal. Ask directly.
2. Who holds the data. Often the vendor, not the insurer, holds it, under its own privacy policy. Read both documents. your data and your home insurer: privacy rules covers your rights.
3. A discount that can disappear. An unplugged or unpaired device, a lapsed subscription or a missed activation window can remove the credit.
4. False confidence. A sensor warns but does not stop water, and a shutoff valve does not replace maintenance. Neither changes what the policy covers. A leak that ran for weeks before anyone noticed can still fall under a gradual damage exclusion (sudden vs gradual water damage: where insurers draw the line).
5. Reliability. Batteries die, Wi-Fi drops and apps stop updating. Test devices twice a year.

Questions to ask before connecting a device

1. What is the credit, and does it apply to the whole premium or only the water, fire or theft portion?
2. Is any data shared with the insurer? What kinds, how often, and for how long is it kept?
3. Can the insurer use it for underwriting, nonrenewal or pricing decisions? Is that stated in writing?
4. Who owns the device and the data if I cancel the policy or the subscription?
5. What proof is required, and when must I activate?
6. What happens to the credit if the device fails or I replace it?
7. Is the device on the insurer's approved list for my state?

If the agent cannot answer, ask the insurer in writing, and keep the reply.

A hypothetical comparison

Say two options are on the table for a home with a $2,400 premium. A free leak sensor from your insurer earns no rate credit and shares no data. An $800 professionally installed shutoff valve earns a 5% credit on the water portion of the premium, say $30 a year, and has a subscription of $0 for the first three years. The credit will not repay the valve in any plausible time. The decision turns on the loss the valve avoids, and on whether the data terms of the program are acceptable.

Other smart-home links to insurance

• Home sharing and short-term rentals. Noise and occupancy sensors are a host's tool, not an insurer's; see Insuring an Airbnb or other short-term rental.
• Security cameras and liability. Cameras generally do not change coverage, though a recorded event can support a theft or liability claim.
• Equipment breakdown. Smart devices that fail may be covered under equipment breakdown coverage: what it pays and who needs it if you have it, not under the base policy.
• Home batteries and EV chargers. These add connected equipment with their own insurance questions; see EV chargers and home batteries: insurance questions.

Key takeaways

• Insurers favor devices that prevent water and fire losses because those claims are costly and often preventable with early warning.
• Programs range from free devices to policy discounts to monitored services; terms differ by insurer and state.
• Data terms matter as much as the discount: ask what is collected, who holds it and whether it can affect underwriting.
• Nationwide says its collected data will not be used to deny a claim; vendor claims about reduced losses, such as Flume's, are not independently verified.
• A device changes how large a loss becomes, not what your policy covers.
