Smart Home Statistics 2026: Adoption, Devices, Spending and Forecasts

Worldwide smart home device shipments reached 892.3 million units in 2024 and are forecast to grow 4.4% to 931.1 million units in 2025, according to IDC’s Worldwide Quarterly Smart Home Device Tracker. Household penetration is climbing in parallel: global smart home penetration will reach 82.1% in 2026 and is expected to hit 92.5% by 2029, with a revenue forecast of $225.7 billion by 2029 at an 8.82% CAGR.

The flip side of that growth is IoT Attacks Per Household: connected households now face nearly 30 IoT cyber-attacks every 24 hours across an average 22-device surface, per NETGEAR Bitdefender telemetry. The Device Count Plateau identified by Parks Associates is the other surprise: the average smart-home household has flattened at 6.2 connected devices, down from a pandemic-era peak of 8, even as the Matter Standard from Connectivity Standards Alliance finally adds cameras and energy management to the cross-vendor stack.

US Smart Home Adoption by Household

• 45% of US internet households own at least one core smart home device, excluding smart speakers, according to Parks Associates’ Smart Home Tracker.
• 20% of US internet households own a video doorbell, the breakout category of the past three years.
• By Q2 2025, nearly half of US internet households owned a home-security solution, a category that includes monitored systems, DIY hubs, and standalone cameras.
• The average smart-home household now sits at 6.2 devices, down from the pandemic-era peak of 8, a cohort Parks Associates frames as the new mainstream smart-home household.
• The US smart home market sits inside a broader technology adoption story driven by smartphone-led app ecosystems and home Wi-Fi penetration above 90%.

Why it matters: Parks Associates’ Daniel Holcomb frames the maturity inflection plainly: The smart home market has matured, expanding the need for better setup experiences and cross-vendor standards. Read alongside the 52% DIY setup-issue rate, the bottleneck is now experience, not awareness.

Average Number of Connected Devices per Household

Source: Parks Associates Smart Home Tracker Q2 2025; Parks Associates Smart Home and Security Market Tracker.

• The number of devices in the average US smart-home household peaked at 8 during the pandemic era and has since dropped to 6.2 as mainstream adopters enter the market with smaller starter setups.
• The long tail of single-device owners pulls the average down even as a smaller cohort of high-engagement households continues to expand its device footprint.
• The category mix inside a typical six-device household skews toward security (video doorbell at 20% household ownership) and entertainment (smart speakers, smart TVs).
• The same Parks Associates research shows 52% of DIY installers report setup or connectivity issues, the demand-side ceiling that holds the average at 6.2 even as new categories ship.
• The smart-home device surface overlaps the broader IoT installed base; not every IoT device is a “smart home” device, but most smart home devices are IoT.

The average US smart-home-owning household carries 6.2 connected devices, down from a pandemic peak of 8, according to Parks Associates’ Smart Home Tracker. New mainstream adopters enter with smaller setups of one or two devices and pull the average down even as high-engagement households continue adding devices on top of their existing footprint.

Smart Speaker and Voice Assistant Usage

• Roughly 45% of US internet households own at least one core smart home device when smart speakers are excluded, which sets a floor on how many also live with a voice assistant.
• Smart speakers and displays continue to anchor most multi-device smart homes; the Parks Associates research puts the average smart-home household at 6.2 devices, with speakers typically the entry point.
• Voice control still leans on the three-vendor stack of Amazon Alexa, Google Assistant, and Apple Siri, with adoption details tracked in our voice assistant usage statistics breakdown.
• The lighter-weight smart-speaker form factor (Echo Dot, Nest Mini, HomePod mini) drives most unit shipments, while smart displays account for a smaller share covered in our smart speaker statistics reference.
• Audio routing through smart speakers also pulls streaming usage upward; the Spotify subscriber base overlaps materially with US smart-speaker households that use voice to start playback.

Amazon leads the US smart home installed base when measured by single-vendor footprint, anchored by Echo speakers, Ring video doorbells, and the eero mesh Wi-Fi platform. On the camera side specifically, Amazon’s Ring accounts for 40% of US video doorbells in use, with Google’s Nest at 24%, per Strategy Analytics tracking that two brands together hold nearly two-thirds of the installed base.

Smart Home Security Camera and Video Doorbell Adoption

• Amazon’s Ring accounts for 40% of US video doorbells in use, followed by Google’s Nest with 24%, per Strategy Analytics tracking of the installed base.
• Video doorbells reached 20% of US internet households by 2023, up from 4% in 2017, a five-fold rise driven mainly by Ring’s product cycle.
• On the platform side, Arlo Technologies has shipped over 41.4 million smart connected devices since December 2014 and now supports approximately 11.8 million registered accounts and 5.4 million paid accounts as of September 28, 2025.
• The wireless camera form factor is now the default at retail; older wired-only doorbell systems still dominate the multi-family and retrofit segment.
• The video-doorbell category illustrates the smart-home conversion path most clearly: a single high-utility device becomes the entry point, and the household typically adds two or three other devices within the following year.

Smart Thermostat Energy Savings

• ENERGY STAR-certified smart thermostats save households approximately 8% of heating and cooling bills, or about $50 per year on average.
• Certified models must demonstrate approximately a heating runtime reduction of at least 8% (lower 95% confidence limit) and a cooling runtime reduction of at least 10% using EPA-supplied analysis software.
• The ENERGY STAR specification for smart thermostats became effective in December 2016, with seven certified models from Nest, Ecobee, and Carrier achieving certification by mid-2017.
• ENERGY STAR-certified thermostats also have to maintain static temperature accuracy of plus or minus 2.0 degrees Fahrenheit and draw no more than 3.0 watts during network standby.
• Smart thermostats are the only smart-home category with an EPA-led, real-world savings test built into certification, which is why the savings claim survives YMYL scrutiny that other “smart home saves energy” marketing does not.

ENERGY STAR estimates average annual heating and cooling savings of approximately 8%, or about $50 per year, per typical US household. The figure comes from EPA-provided software analyzing real-world data across a large sample of homes, not lab tests, so it reflects actual usage patterns across climate zones, occupancy schedules, and HVAC equipment types.

Matter Standard Adoption and Interoperability

• The Matter working group formed in December 2019 with founding members Amazon, Apple, Google, Samsung SmartThings, and the Zigbee Alliance, now operating under the Connectivity Standards Alliance.
• Matter version 1.0 was published on 4 October 2022, turning a multi-year cross-vendor project into a shipping standard.
• Version 1.5 was published on 20 November 2025 and added cameras, soil moisture sensors, and energy management features, the most expansive single update since launch.
• CSA followed with Matter version 1.6 in June 2026, extending coverage further into appliances and energy management.
• Camera support in Matter 1.5 matters because cameras are the highest-revenue smart-home category, and bringing them under a cross-platform standard removes the largest ecosystem-lock-in friction for households shopping across Apple Home, Alexa, Google Home, and SmartThings.

Matter adoption ramped sharply from 2024 to 2026. Founding members Amazon, Apple, Google, and Samsung have all shipped Matter support across their hub and speaker lines, and subsequent Connectivity Standards Alliance members include IKEA, Huawei, Heiman, and Schneider. The November 2025 1.5 release added cameras and energy management, the two categories that had previously kept multi-vendor smart homes fragmented.

Smart Home Cybersecurity and Privacy Risks

• A connected household now faces nearly 30 cyber-attacks every 24 hours across an average 22-device IoT surface, according to NETGEAR and Bitdefender’s 2025 IoT Threat Report.
• The same report analyzed telemetry from 6.1 million households and 13.6 billion IoT attacks to produce the per-household attack rate.
• Common entry points include smart door locks, IP cameras, alarm systems, and thermostats, where weak passwords, firmware vulnerabilities, and weak network controls remain the primary attack surfaces.
• Smart-home devices remain vulnerable due to weak defaults, long device lifecycles, and limited firmware update support across the manufacturer landscape.
• Enabling per-device strong passwords, network segmentation (a separate IoT VLAN), and automatic firmware updates helps reduce the practical attack surface even before vendor patches arrive.

Worth noting: The 29-attacks-per-day figure is drawn from passive telemetry across 6.1 million households and 13.6 billion IoT attacks and reflects automated scans, login attempts, and exploit probes, not successful breaches. The metric is a load measure of the threat landscape per household, not an outcome metric. Successful compromise rates run far lower but rise sharply on unpatched devices.

Regional Smart Home Market: Asia-Pacific and China

• China generates $40.2 billion in 2026 smart-home revenue, the largest single-country contribution to the global market.
• The worldwide market is forecast to reach $225.7 billion by 2029 at an 8.82% CAGR from 2026.
• Average revenue per installed smart home worldwide stands at $22.16, a figure pulled down by mass-adoption emerging markets and pulled up by high-spend North American and Western European households.
• IDC notes North America and Western Europe are forecast to decline while Asia/Pacific and Latin America still have room to grow, the structural reason worldwide shipment growth is now driven by emerging markets.
• China’s contribution and the lower global ARPU together explain why headline market-size figures vary so widely between vendor reports.

Smart Lighting Market and Adoption

Source: Vendor product documentation and CES 2026 announcements; positioning verified against current product lines.

• Smart lighting sits inside the broader connected-device mix, alongside the over a quarter share of total smart-home shipment volume that home monitoring and security categories hold combined in IDC’s forecast.
• Matter 1.5 added expanded support for additional device categories on 20 November 2025, with lighting one of the earliest categories to ship Matter-compatible firmware across vendors.
• Wearables overlap the smart-lighting trigger pattern (sleep tracking on smartwatches drives “wake-up light” routines), tying lighting use into the broader connected-device data stack.
• Lighting is the least-talked-about smart-home category but the most-bought entry product: a single smart bulb or strip is often the first connected device a household installs, well before a speaker or doorbell.
• For the cross-category technology adoption context, see our broader technology growth statistics coverage.

Conclusion

Worldwide smart home shipments climbed from 892.3 million units in 2024 to a forecast 931.1 million units in 2025, and household penetration is on track from 82.1% in 2026 to 92.5% by 2029. The average US smart-home household now carries 6.2 connected devices across security, lighting, audio, and HVAC categories, with Matter standardization closing the cross-vendor gaps that previously capped multi-ecosystem installs.

The next phase belongs to households entering with smaller, more interoperable setups. Brands that win the next cycle will solve the 52% DIY setup-issue rate and harden devices against the 29-attack-per-day baseline.
