Five Years Later: We Checked the Resale Price of Yesterday's Smart Home Gear (and Found Out What's Basically E-Waste)

The Smart Home Garage Sale Nobody Talks About

Every smart home owner eventually has The Drawer. You know the one — stuffed with the first-gen bulb that stopped pairing, the hub from a brand that got acquired (and then gutted), and the motion sensor that only works if you believe hard enough.

We got curious: what's all that gear actually worth on the secondhand market? So we spent a month tracking sold listings on eBay and Facebook Marketplace for a mix of discontinued hubs, out-of-date bulbs, and sensors whose parent ecosystems no longer exist. The results were humbling — and occasionally surprising.

The Winners: Gear That Actually Holds Value

Lutron Caséta dimmers and switches. Hardwired devices that replace dumb switches are the closest thing smart home gear has to a blue-chip stock. Even five-year-old Caséta units routinely sell for 40–60% of retail because they're wired into your walls — nobody wants to rewire to upgrade, so buyers hunt for used ones.

Yale and Schlage smart locks. Locks from major brands with replaceable cylinders and swappable modules keep a chunk of their value. A 2019 Schlage Encode in decent shape still pulls $50–70.

Big-name hubs with active ecosystems. A used SmartThings hub (the Samsung-era ones) still sells, because the platform lives on. Same with HomePod minis and Echo devices — cheap new, but they move fast used because buyers know Alexa and HomeKit aren't going anywhere.

The Losers: The Drawer-of-Doom Tier

Cloud-dependent hubs from dead companies. Remember Insteon's 2022 server scare? Or Wink's subscription flip-flops? When the cloud dies, the hardware becomes a paperweight overnight. Used listings for orphaned hubs exist, but they sell for parts — literally.

Proprietary-protocol bulbs. Older Wi-Fi bulbs from no-name brands are functionally worthless used. Even first-gen Hue color bulbs, once the crown jewel, now sell for $5–10 a pop because new ones got so cheap.

Single-ecosystem sensors. That SmartThings multi-sensor from 2018? Worth a few bucks, max. Sensors are the fast-depreciating sedans of the smart home world.

What This Means When You're Buying

Here's the practical takeaway: hardwired and standards-agnostic gear ages well; cloud-tethered and proprietary gear doesn't. A $30 smart switch that works locally via Matter or Z-Wave will likely still have a functioning home in 2030. A $25 Wi-Fi bulb that depends on someone's app servers probably won't.

Before you grab the cheapest option, ask: does this work without the vendor's cloud? Is it on Matter or Thread? Does the company have a track record of supporting old gear? Paying $10 more now can mean the difference between reselling it later and tossing it.

Wiping Your Gear Before You Sell (Yes, It Matters)

Smart locks remember codes. Cameras store clips. Hubs know your Wi-Fi password and, often, your schedule. Before you box anything up:

1. Factory reset everything — check the manufacturer's site; the reset procedure is rarely intuitive (often it's a paperclip held for 10 seconds).
2. Remove the device from your app first. Unclaimed devices are easier for buyers to onboard, and it severs the device's link to your account.
3. For locks, delete all user codes and rekey or replace the cylinder if it was installed on an exterior door.
4. For cameras, check for local storage — SD cards should be wiped or pulled.
5. Include the original QR codes or pairing info if you have them; it genuinely boosts resale.

Donate or Dump?

Working gear that won't sell — those $5 bulbs, the extra sensor — still has life in it. Goodwill and local charities take functioning smart devices, and programs like Seattle's RePC or regional e-waste recycles handle the truly dead ones. What you shouldn't do is trash it: smart plugs and hubs contain batteries and circuit boards that don't belong in a landfill.

The Bottom Line

The smart home resale market rewards boring, durable, standards-based gear and punishes shiny, cloud-dependent gadgets. Buy with the drawer in mind: every device you bring home is either a future listing or future e-waste. Choose accordingly.
