The 5 Smart Home Gadgets That Aren't Worth It (2024)

TL;DR: Five popular smart home gadgets — smart light bulbs sold by the room, smart faucets, robot mowers, smart garbage cans, and app-controlled smart locks with weak batteries — cost $150 to $600 more than manual alternatives and rarely earn that back in convenience or savings. A $15 dimmer switch, a $40 timer, or a $200 quality deadbolt often does the job better and lasts longer without a subscription fee.

You've seen the ads: buy this gadget, save money, live smarter. Half of them end up in a drawer within a year, and the other half quietly bill your credit card every month for an app you barely open. Here are the five that tend to disappoint owner-operators, and what actually earns its keep instead.

Okoniq Property Hub helps you track which gadgets you've installed, when warranties expire, and whether a device is actually pulling its weight across your properties.

Are smart light bulbs worth the upgrade?

Rarely, once you tally the real cost. A single smart bulb runs $15 to $50, and outfitting one room with 6 to 8 bulbs easily hits $200 to $400 — for a feature a $15 smart dimmer switch or a $10 mechanical timer already covers for the whole room.

Most homeowners use maybe 10% of the app's features after the first month: change color, dim, schedule. A basic dimmer switch on the existing wiring does two of those three for a fraction of the price, with no app, no Wi-Fi dependency, and no risk of the bulb becoming unsupported when the manufacturer discontinues its app in three years (this has already happened with at least two major bulb brands since 2020).

If you rent units out, smart bulbs also complicate turnover — tenants either don't know how to use them or unpair them from your account, and you're buying replacements every lease cycle.

Do smart faucets actually save water or money?

Not enough to justify the price tag for most kitchens. A touchless or voice-activated faucet costs $250 to $500 installed, versus $80 to $150 for a standard high-quality faucet. The water savings from touchless activation are marginal — you're paying mostly for convenience, and the electronic components (batteries or hardwired sensors) are the first thing to fail, often within 3 to 5 years.

Repair costs for smart faucets run higher too, since most plumbers stock parts for standard fixtures, not proprietary sensor modules. If a fitting fails at 2am, you're looking at a full replacement rather than a $20 cartridge swap. For actual water savings, a low-flow aerator ($5) does more per dollar than any smart faucet on the market.

Are robot lawn mowers a good investment for landlords?

Only if your lawn is small, flat, and fenced — otherwise, no. Robot mowers cost $600 to $1,500 upfront plus a boundary wire installation that runs another $100 to $300. They struggle with slopes over 20 degrees, uneven yards, and anything larger than a quarter acre without a premium (often $2,000+) model.

Compare that to a $300 to $500 gas or electric push mower that a tenant or handyman can run in 30 minutes every two weeks. Robot mowers also get stolen — insurance claims for missing robot mowers have risen enough that some manufacturers now sell GPS tracking as a paid add-on. If you're managing rental properties where you don't control who's watching the yard, this is a gadget that adds risk without adding value.

| Feature | Robot Mower | Standard Push Mower | |---|---|---| | Upfront cost | $600–$1,500+ | $300–$500 | | Works on slopes | Limited (under 20°) | Yes | | Theft risk | Higher (outdoor, unattended) | Lower | | Maintenance | Blade + battery + app | Blade + oil/gas |

Are smart trash cans and smart locks worth the money?

Smart trash cans, rarely. Smart locks, sometimes — but only the right kind. A sensor-lid trash can that opens automatically costs $100 to $200 and mostly just adds a battery to replace and a motor to jam. It solves a problem — touching a lid — that a foot pedal can already solve for $20.

Smart locks are a mixed case. A cheap $80 to $120 smart lock with a weak battery and a flimsy internal mechanism will strand a tenant in the cold when the battery dies mid-winter, and swapping AA batteries every 3 to 6 months becomes a recurring landlord headache across multiple units. A $200+ mid-range smart lock with a physical key backup and a 12-month-plus battery life is a reasonable upgrade, especially for short-term rentals where remote code changes save you a trip. The gadget itself isn't the problem — buying the cheapest version of it is. If you're weighing electrical upgrades around entry points, it's also worth checking your panel capacity; see our breakdown on 100 vs 200 amp service before adding more connected devices to an older system.

What smart home gadgets are actually worth buying?

Leak sensors and smart thermostats are the two categories that consistently pay for themselves. A $30 to $50 water leak sensor placed near a water heater or under a slab-prone floor can catch a slow leak before it becomes a $3,000 repair — the kind of damage covered in our post on signs of a slab leak under your floor. Similarly, if you're already watching for water pooling under your water heater, a $25 sensor does that watching for you around the clock.

Smart thermostats ($130 to $250) genuinely cut heating and cooling costs 10% to 15% a year according to most manufacturer and utility studies, and they pair well with routine upkeep like the filter swaps covered in 1-inch vs 4-inch furnace filters. Humidity sensors are worth a mention too — cheap ($20 to $40) and useful for catching moisture problems early, similar to what we cover in signs your crawlspace vapor barrier has failed.

FAQ

What's the biggest mistake people make with smart home gadgets?

Buying the gadget before checking if a $15 to $50 mechanical alternative already solves the same problem. Most disappointment comes from paying $200+ for convenience that a switch, timer, or pedal delivers for a tenth of the cost.

Do smart home devices increase home resale value?

Not reliably. Appraisers rarely add value for smart bulbs, locks, or plugs, and buyers often see proprietary systems as clutter they'll have to reconfigure or remove, especially if the app requires an account transfer.

Are smart home subscriptions a hidden cost?

Yes, often. Video doorbells, some smart locks, and cloud-storage cameras can run $3 to $15 a month per device — across 4 or 5 devices in a rental portfolio, that's $150 to $900 a year in fees that never show up in the sticker price.

How long do smart home gadgets actually last?

Most connected devices last 3 to 5 years before the app is discontinued or the hardware fails, compared to 10 to 20 years for a standard mechanical switch, lock, or faucet.

Is a smart thermostat worth it for a rental property?

Usually yes if you self-manage heating costs, since a $150 to $250 thermostat can cut utility bills 10% to 15% annually and lets you monitor temperature remotely between tenants.
