2021 Top 10 Smart Home Picks: Best Kickstarter Home Tech Products
Kickstarter's strongest smart-home campaigns of 2021 did more than add an app. They made complex household jobs easier to see and control: backup power, cooking, indoor growing, fitness, beauty routines, and wall-mounted controls all became clearer product systems.
BackerRock Signal
These ten campaigns reported about US$20.81 million in Kickstarter funding from 18,816 backers. The top three generated roughly 82.2% of reported USD funding, while the remaining projects showed demand spreading across smaller, task-specific home systems.
Eligibility requires a Kickstarter funding period that began in 2021. Rankings use Kickstarter's reported USD comparison value; project sections preserve original currency, backer count, dates, and a public-evidence check dated September 4, 2026.

What the Numbers Say About 2021 Smart Home
Home energy set the funding ceiling
EcoFlow and BLUETTI alone accounted for about US$15.30 million, or 73.5% of the list total. Buyers were willing to fund premium systems when capacity, output, recharge paths, and outage use were demonstrated clearly.
Backer volume was not limited to the biggest raise
Nimble and SONOFF together attracted 9,540 backers. Their totals show that focused household control can reach a wide audience even when the individual purchase is smaller than a home battery.
The smart home expanded beyond lights and locks
Kitchen systems, fitness equipment, indoor gardening, beauty robotics, and local-first entertainment control all qualified because connected intelligence was tied to a repeated household job.
BackerRock takeaway
The 2021 winners did not sell connectivity by itself; they sold a clearer way to control energy, time, space, or repeatable results at home.
