Can Smart Home Devices Lower Your Insurance? (2024)

TL;DR: Most major insurers, including State Farm, Allstate, and Nationwide, offer discounts of 2% to 15% for smart water sensors, monitored smoke detectors, and security systems. Water leak sensors have the fastest payback since water damage is the most common non-catastrophe claim, averaging over $11,000 per incident. Call your agent before buying anything; discounts and required devices vary by state and carrier.

You've seen the ads for smart smoke detectors and leak sensors that promise to shave money off your homeowners policy. The pitch is real, but the discount amount and which devices qualify depend entirely on your insurer, your state, and how you install the gear. Here's what actually moves the needle.

Okoniq Property Hub helps homeowners track which smart devices are installed, when they were tested, and whether they're linked to an insurance discount, so you have proof ready at renewal time.

Which smart devices actually qualify for a discount?

Water leak sensors, monitored smoke and carbon monoxide detectors, and professionally monitored security systems are the three device categories most insurers recognize. Some carriers, like Liberty Mutual and American Family, also credit smart thermostats and smart locks, though those discounts tend to be smaller, often under 2%.

Water sensors get the most attention right now because water damage and freezing account for roughly 24% of homeowners insurance claims nationally, and the average claim runs over $11,000, according to Insurance Information Institute data. Devices like Flo by Moen or Ting monitor for leaks or electrical fire risk continuously, and several insurers, including American Family, will knock 5% to 10% off a policy just for having one installed on the main water line.

If you've had water pooling near appliances before, pair a sensor with a fix at the source. Check 5 reasons water pools under your water heater if that's been an ongoing issue, since a sensor alerts you to a problem but doesn't solve a failing tank.

How much can you actually save?

Discounts typically range from 2% to 15% of your annual premium, and they rarely stack to the full amount if you install multiple device types. A monitored security system alone might get you 5% to 10% off, since it reduces burglary and vandalism risk. Add a water sensor and you might get another 2% to 5%, but insurers often cap total smart-device discounts around 15% to 20% combined.

On a $1,800 annual premium, a 10% discount saves $180 a year. That's real money, but it won't cover the cost of a full smart security system in year one. Ask your agent for the exact percentage in writing before you buy anything, since marketing materials from device manufacturers often overstate what carriers actually apply.

Does a monitored security system matter more than smoke detectors?

Yes, for discount size, but smoke and CO detectors matter more for safety and are sometimes required. Monitored security systems tend to carry the largest single discount because they address theft, vandalism, and fire response time simultaneously. A system with 24/7 professional monitoring, like ADT or SimpliSafe's monitored tier, typically qualifies for a bigger discount than a self-monitored camera setup, because the insurer is paying for faster emergency response, not just deterrence.

| Device Type | Typical Discount | What It Protects Against | |---|---|---| | Monitored security system | 5-10% | Theft, vandalism, fire response delay | | Water leak sensor | 2-10% | Water damage, freeze claims | | Smart smoke/CO detector | 1-5% | Fire, carbon monoxide | | Smart thermostat/lock | 0-2% | Minor risk reduction, rarely a standalone discount |

If your home still has an older electrical panel, a smart smoke detector won't offset the underlying risk. Homes with outdated wiring see higher fire claim rates, so it's worth checking 100 vs 200 amp service: do you have enough power? and 5 signs you still have knob-and-tube wiring before assuming a $50 detector solves a wiring problem.

What should you check before buying anything?

Call your insurance agent first and ask three specific questions: which devices qualify, what percentage discount applies, and whether the device needs professional installation or monitoring to count. Some insurers only credit systems installed by a licensed contractor with a service contract, not DIY kits from a big-box store.

Also confirm the discount isn't offset by a device-related exclusion. A few policies reduce water damage coverage if a sensor is present but not properly maintained, on the theory that you had warning and didn't act. Keep dated proof of installation, testing, and any alerts you responded to, since claims adjusters may ask for it.

Old electrical work is a common source of both fire risk and rejected discounts. If your outlets are still two-prong, that's often a red flag to an underwriter before a smart device discount even comes up. See 2-prong vs 3-prong outlets: how to upgrade safely if that applies to your home.

FAQ

Do smart home devices lower insurance for renters too?

Yes, renters insurance discounts follow similar rules, though the percentage is usually smaller, often 2% to 5%, since dwelling coverage isn't part of a renter's policy.

Will a smart thermostat lower my insurance premium?

Rarely by itself. Most carriers treat smart thermostats as a minor factor worth 0% to 2%, since they reduce freeze-related pipe bursts but don't address major claim categories like theft or fire.

Do I need professional monitoring to get the discount?

Often yes for security systems. Many insurers require 24/7 professional monitoring, not just a self-monitored app alert, to qualify for the full 5% to 10% discount.

How long does it take to see the discount on my bill?

Most insurers apply it at your next renewal after you report the device, typically within 30 to 60 days of notifying your agent, though some require photo or receipt documentation first.

Can installing a water sensor void part of my coverage instead of helping?

In rare cases, yes, if the policy has language requiring you to act on sensor alerts. Read your policy's water damage clause carefully or ask your agent directly before assuming the sensor only helps.
