Costco has quietly become a reliable source for practical smart-home gear, and this round-up identifies five widely available items that deliver measurable value. In recent years interest in smart home technology has surged—about seven in 10 people say they are interested and over 90% now own at least one smart device—while the market is forecast to approach $400 billion over the next decade. We evaluated the highest-rated, best-reviewed smart-home products sold at Costco (online and in warehouse) and selected five that address common household problems and offer clear performance or savings benefits. Each pick preserves broad compatibility and strong member value without counting novelty gadgets.
Key Takeaways
- Smart-home demand is high: roughly 70% of people express interest and more than 90% already own at least one device, with the market projected near $400 billion over the next decade.
- The ecobee Smart Thermostat Premium Plus Pack (two SmartSensors) posts a 4.6-star rating on Costco with 700+ reviews and is available for $229.99, claiming up to 26% in HVAC savings.
- Sonos Era 100 two-pack is rated 4.5 stars by 600+ reviewers at Costco and is on sale for $334.99 (currently $75 off until Feb. 16), offering strong stereo imaging and multiroom Wi‑Fi streaming.
- TP-Link Deco X60 Wi‑Fi 6 AX3000 mesh (3-pack) has a 4.4-star rating from 3,300+ reviewers, advertises coverage up to 7,000 sq ft and aggregate speeds to 3 Gbps, and lists for $139.99 at Costco.
- The 13-piece SimpliSafe package (two 1080p outdoor cameras) holds a 4.5-star rating from 94 reviews, is priced at $349.99, and includes battery backup plus dual cellular/Wi‑Fi connectivity for resilience.
- Rachio 3 WiFi Smart Sprinkler Controller is rated 4.7 with 4,300+ reviews on Costco and costs $199.99; Rachio states the controller can cut water use by up to 50% through weather-aware scheduling.
- Selection criteria: every item here has a Costco rating of at least 4.4 stars and a review count judged meaningful for the rating; we limited one representative product per subcategory to avoid overlaps.
Background
Adoption of connected devices has accelerated but remains uneven across categories. Consumers commonly seek convenience, cost savings and safety, yet the range of available products—from low-cost single-purpose gadgets to more integrated systems—creates confusion at the point of purchase. Big-box retailers like Costco increasingly curate bundles and branded packs that reduce setup complexity and offer a price premium for membership customers, especially on staple categories such as thermostats, speakers, mesh Wi‑Fi, security systems and irrigation controllers.
Manufacturers have responded by emphasizing interoperability, cloud features and subscription options—choices that affect long-term cost and privacy. Meanwhile, network reliability and local environmental data (for things like sprinklers and thermostats) have become central to real-world performance. For many households, a limited number of reliable, well-reviewed devices delivers more practical benefit than an overabundance of gimmicks.
Main Event
Ecobee’s Smart Thermostat Premium Plus Pack is a full-featured thermostat that bundles two SmartSensors to reduce room-to-room temperature variance. Costco’s listing shows a 4.6-star average from over 700 reviews and a member price of $229.99. Ecobee promotes automated schedules, occupancy-based adjustments and built-in air-quality and smoke alerts, which together target both comfort and utility-bill reductions.
Sonos supplies a two-unit Era 100 set aimed at users who want immediate multiroom audio via Wi‑Fi without the hassles of wired speakers. Costco reviewers (4.5 stars, 600+ reviews) praise the unit’s stereo separation and bass for its size; the set is offered for $334.99 while a $75 discount runs through Feb. 16. Native support for AirPlay and Alexa makes it straightforward to integrate with existing smart ecosystems.
TP‑Link’s Deco X60 mesh kit addresses a different but foundational problem: connectivity. With Wi‑Fi 6, a claimed top speed to 3 Gbps and coverage up to 7,000 sq ft for a three‑pack, the Deco X60 is presented as the backbone that enables reliable device operation across large or multi‑story homes. Costco’s price of $139.99 for the set and user ratings (4.4 stars, 3,300+ reviews) suggest strong adoption among members.
SimpliSafe’s 13-piece security bundle includes a base station, keypad, eight entry sensors, a motion sensor and two Series 2 1080p outdoor cameras. The package, rated 4.5 by 94 Costco reviewers, emphasizes ease of installation, wireless components, battery backup and both cellular and Wi‑Fi failover to maintain monitoring during outages—an important resilience factor for home safety systems.
Finally, the Rachio 3 smart sprinkler controller converts traditional dial systems into a weather-aware, 12‑zone controller. With a 4.7-star Costco rating from 4,300+ reviewers and a $199.99 price, Rachio leans on hyperlocal weather inputs—rain, wind and freeze skips—to optimize watering and reduce waste, claiming potential water reductions up to 50% under ideal conditions.
Analysis & Implications
These five products exemplify how targeted upgrades can produce measurable benefits: energy savings from smarter HVAC control, lower water use from an adaptive irrigation hub, fewer network dropouts from modern mesh Wi‑Fi, clearer audio via Wi‑Fi speakers, and more resilient security coverage. Economically, the combined upfront cost for well-selected devices can be amortized through utility and resource savings or avoided replacement/repair costs associated with poor performance.
Retail bundling at Costco changes the purchase calculus for many consumers by reducing friction: prepackaged sensor counts, paired accessories and member pricing simplify decision-making and can improve the value proposition versus piecing components together from different vendors. However, membership-only discounts mean the full benefit is limited to warehouse members.
Privacy, subscription models and product longevity remain open considerations. Many smart devices rely on cloud services for advanced features; buyers should weigh subscription fees and the vendor’s update policy. Additionally, the increasing reliance on a home network elevates the importance of secure router configurations and firmware maintenance to protect connected devices from compromise.

The table summarizes Costco ratings, review counts and advertised benefits. Review counts vary widely—from dozens to thousands—so the confidence in average ratings differs by product. Higher review volumes (TP‑Link, Rachio) strengthen the reliability of the star average, while lower review counts (SimpliSafe) still reflect positive reception but with wider statistical uncertainty.

Unconfirmed
- Individual savings figures (up to 26% HVAC, up to 50% water) are manufacturer-stated estimates; actual savings will vary by home size, climate and user behavior.
- Local Costco inventory and promotional pricing may differ by warehouse and can change after the publication date; availability is not guaranteed.
- Long-term software support and subscription costs for advanced features vary by vendor and are not fully reflected in Costco listings.
Bottom Line
For most households seeking practical improvement, these five Costco-available items represent high-impact upgrades across energy, water, safety and connectivity. They combine strong member pricing with meaningful, review-supported performance in their categories, but buyers should check compatibility (HVAC wiring standards, sprinkler zone counts, home network requirements) before purchase.
When prioritizing upgrades, start with network reliability and a bracketed plan for either climate control or security—the two areas most likely to yield recurring savings or risk reduction. Finally, treat manufacturer savings claims as directional: expect benefits, but validate them in your own home and account for potential subscription or update costs when calculating long-term value.
