Insurers are offering real discounts for smart locks, water sensors, and security systems in 2026 — but not every gadget earns its keep. Here's what's actually worth installing.
Homeowners and renters insurance premiums have climbed steadily over the past few years, and insurers have found a new lever to nudge costs down: smart-home devices. Install a water leak sensor, a smart smoke detector, or a monitored security system, and many carriers will knock a percentage off your premium. The catch is that discounts vary wildly by insurer and device type, and some popular smart-home gadgets don't move the needle on your premium at all, no matter how much they improve your daily life.
Insurance pricing is fundamentally about risk. A device that reduces the odds or severity of a claim, like water damage or theft, is worth a discount to the insurer because it lowers their expected payout. Devices that don't reduce claim risk, even genuinely useful ones like smart thermostats or robot vacuums, typically don't earn a discount because they don't change the insurer's math. That's the filter to run every smart-home purchase through if a premium discount is part of your motivation: does this device reduce the chance of fire, water damage, or theft, or does it just make life more convenient?
Water leak and freeze sensors are consistently among the highest-value additions. Water damage is one of the most common and expensive homeowners claims, and a sensor that shuts off your main water valve automatically when it detects a leak, not just one that sends an alert, tends to earn the biggest discounts — often in the 5 to 10% range for water-related coverage, depending on the carrier. Monitored smart smoke and carbon monoxide detectors that alert a monitoring service (not just your phone) also tend to qualify, since fire damage claims are severe and insurers reward faster response times.
Smart security systems with professional monitoring are the other major category. A doorbell camera alone usually isn't enough to trigger a discount, but a monitored system that includes entry sensors, motion detection, and a connection to a monitoring center can qualify for meaningful discounts, sometimes 5 to 15% depending on the insurer and your location's burglary rates. Some insurers also offer smaller discounts for smart locks, mainly because they reduce the chance of someone leaving a door unlocked, though this discount tends to be modest compared to leak sensors and full security systems.
Smart thermostats, smart lighting, robot vacuums, and voice assistants are genuinely nice to have, but they rarely affect your insurance premium because they don't reduce claim-worthy risks in the way insurers measure them. Some utility companies offer separate rebates for smart thermostats tied to energy efficiency, which is worth chasing for a different reason, but don't expect it to show up on your insurance bill. Video doorbells without a monitored alarm system attached also tend to fall into this category — useful for package theft and general peace of mind, but not typically discount-eligible on their own.
The device alone rarely triggers anything automatically. Most insurers require you to report the device, sometimes through a partner app that verifies installation, and some only offer discounts for specific brands they've partnered with. Before buying anything, it's worth calling your insurer or checking your policy portal to ask which specific devices and brands qualify, since a leak sensor from one manufacturer might qualify while an equally good one from another brand doesn't, purely because of which company your insurer has a data-sharing partnership with. If you're shopping for home insurance and comparing carriers, it's worth asking this question during the quote process rather than after you've already bought the hardware.
Omar and his wife Fatima were quoted $1,840 a year for homeowners insurance on their three-bedroom house. Their insurer offered a bundled smart-home discount program: installing a water sensor near their water heater and washing machine, plus enrolling their existing monitored security system in the insurer's partner app, dropped their premium to $1,646 a year, a savings of $194. The water sensor itself cost $140 upfront, so it paid for itself in under a year and kept paying every year after.
Their neighbor, Beatriz, went a different direction. She spent close to $600 on a full smart-lighting and smart-thermostat setup, expecting a similar insurance break, and was surprised to learn her insurer didn't offer any discount for either device. She still likes the lower energy bills the thermostat delivers, but it didn't touch her insurance premium the way she'd assumed it would.
The most common mistake is buying smart-home gadgets first and asking about insurance discounts second, which is backward — the discount programs and qualifying brands vary enough that it's worth checking before you spend. Another mistake is assuming any "smart" label automatically means insurer-approved; a basic app-connected leak alarm that only sends a phone notification is very different, in an insurer's eyes, from one that automatically shuts off your water main. People also frequently overlook that discounts often require ongoing enrollment in a monitoring app or data-sharing program, not just a one-time purchase, so read the fine print about what staying eligible requires. Finally, don't assume renters insurance offers the same discount menu as homeowners insurance; renters policies sometimes have a much narrower list of qualifying devices, if any.
Call your insurer or check your policy app before buying anything, and ask specifically which smart-home devices and brands qualify for a discount on your policy. Prioritize water leak sensors near appliances most likely to fail, like water heaters, washing machines, and dishwashers, since these tend to offer the best discount-to-cost ratio. If you already have a monitored security system, confirm it's properly registered with your insurer, since an unregistered system earns you nothing. And treat energy-focused smart devices like thermostats as a separate financial decision from insurance, evaluated on utility savings rather than premium reduction.
Smart-home devices can genuinely lower your insurance premium, but only the ones that measurably reduce the risk of a claim, mainly water damage and theft. The gadgets that make your house feel futuristic, lighting, voice assistants, robot vacuums, are worth buying for their own reasons, just not this one. A quick call to your insurer before you shop can be the difference between a device that pays for itself and one that's simply a nice convenience.
