“Save 45%” on a smart home device sounds straightforward until you check what it’s actually being compared against. Black Friday and Prime Day pricing in this category is measured against a list price that was quietly inflated beforehand specifically to make the eventual “sale” look bigger, not against what the device has actually sold for the rest of the year.
Here’s when these sales actually happen, how to tell a genuine discount from an inflated one, and which smart home categories are actually worth waiting for.
When the Sales Actually Happen (and Why There Are Three of Them Now)

Smart home shopping events aren’t a single day anymore. They’re a stretch of the calendar with three real windows. Amazon Prime Day, traditionally a mid-July event, has been joined by a second fall event, often called Prime Big Deal Days or October Prime Day, that’s become a genuine preview of Black Friday pricing.
Black Friday and Cyber Monday then close out the year in late November, running as a single extended window rather than a single Friday. Most years the discounts start landing in the weeks before the actual date and continue through the following Monday.
The practical effect of three windows instead of one is that “wait for Black Friday” isn’t always the right advice anymore. Some categories, smart speakers and streaming devices in particular, now see their deepest discounts of the year during the October event rather than in November, since Amazon uses it to clear inventory ahead of the holiday rush.
Check the price history rather than assuming November is automatically cheapest. It’s worth doing before waiting.
The Fake-Discount Problem: Why the Percentage on the Tag Doesn’t Mean Much

This is the single most important thing to understand before shopping any smart home sale. Retailers, including Amazon itself and many third-party smart home brands, commonly display a “was” price that reflects an inflated list price the device rarely or never actually sold at, then compare the sale price against that inflated number to advertise a bigger discount than actually happened.
A device with a genuine year-round street price of around $43 might display a “was $60, now $40” banner during a sale, a real savings of about $3, dressed up to look like a 33% discount instead of the roughly 7% it actually is.
This isn’t a rare edge case. People who track these sales professionally describe this as standard practice across Black Friday and Prime Day pricing, specifically in this category. It doesn’t mean every advertised discount is fake. Some genuinely are the lowest price of the year, but it means the percentage on the badge tells you almost nothing on its own.
How to Check Whether a “Deal” Is Actually a Deal

Free browser extensions built specifically for this (Keepa and CamelCamelCamel are the two most established) show a price history graph for almost any product on Amazon, letting you see what a device has actually sold for over the past several months or years, not just the inflated reference price sitting next to today’s sale tag.
Installing one before a sale event, not during it, means you can check a device’s real baseline in seconds instead of taking a discount percentage at face value in the moment.
Another thing worth checking is whether a device’s price has actually dropped at all recently outside of a labeled “sale.” Some smart home products cycle through frequent flash discounts throughout the year that land close to or at the same price as the big November event, which means “wait for Black Friday” saves nothing if the device already hit that price in March.
A five-minute price-history check before buying, comparing today’s number against the actual trend line rather than the manufacturer’s list price, catches both problems at once.
Which Smart Home Categories Actually Get Deep Discounts

Not every category benefits equally from sale season, and it’s worth budgeting attention accordingly. Security cameras, video doorbells, robot vacuums, and smart locks tend to see the deepest cuts in real dollar terms, both because they’re the highest-priced categories to begin with and because competition between brands in those categories is fierce enough to push genuine price wars during major sale events.
If a lock or a doorbell is on your list, these are the windows actually worth waiting for; our guides to whether smart locks are actually safer and what a video doorbell is really paying for are worth reading before you shortlist a specific model.
Smart plugs, bulbs, and sensors are the opposite case. They’re cheap year-round, so even a large-looking percentage discount translates to a small dollar amount, a few dollars off an already-inexpensive device.
That doesn’t mean skip them entirely. A $10 plug for $6 is still worth grabbing if you need one anyway, but it means there’s little reason to wait for a sale event to buy this category. Our breakdown of what smart plugs actually do is worth reading any time of year.
Smart thermostats fall somewhere in the middle: real savings show up during sale season, but a utility rebate, covered in our smart thermostat guide, can sometimes beat a Black Friday discount outright and is available year-round.
A Simple Pre-Sale Shortlist Strategy

The best Black Friday and Prime Day prices tend to last hours, not days, which makes real-time comparison shopping during the event itself impractical. The better approach: shortlist the two or three specific devices you actually want in the weeks before the sale starts, check each one’s price history so you already know its real baseline, and set a personal target price based on that history rather than whatever badge shows up on the day.
This matters more for a full smart home build than a single device, since it’s easy to get pulled into buying whatever’s discounted that day rather than what actually fits your setup.
If you’re building out a starter kit around sale season, our budget starter kit guide covers a sensible buying order that holds up whether or not everything on the list happens to be discounted at the same time, and our full cost breakdown is useful for setting a realistic total budget before the sale event tempts you past it.
What Not to Buy Just Because It’s On Sale

A steep discount is a bad reason to buy a device that doesn’t fit your ecosystem, your existing wiring, or your actual needs. A heavily discounted smart thermostat that turns out to need a C-wire your house doesn’t have, or a doorbell tied to a voice assistant you don’t use, isn’t a good deal at any price.
It’s a return waiting to happen, and returns are exactly what sale-season impulse buying produces at a higher rate than normal. Confirm compatibility and actual need before checking the price, not after.
It’s also worth being skeptical of bundle deals that pair a device you want with two or three you don’t, priced to look like a better overall discount than buying the one item alone. Check whether the individual item’s discount alone beats the bundle price before assuming more included items means better value.
And if you’re shopping for someone else during this stretch of the calendar, our smart home gift guide covers the recipient-side considerations, ecosystem, subscriptions, and setup complexity that a discount badge won’t tell you anything about.
Frequently Asked Questions
Is Black Friday actually the cheapest time to buy smart home devices?
Often, but not always. Security cameras, doorbells, locks, and robot vacuums do tend to hit genuine yearly lows during Black Friday and Cyber Monday. Smart speakers and some Amazon-brand devices frequently hit an equal or better price during the October Prime Day event instead. Checking a price-history tool before assuming November is automatically the best time is worth the five minutes it takes.
How can I tell if a discount percentage is real?
Use a free price-history tool like Keepa or CamelCamelCamel, both available as browser extensions, to see what a device has actually sold for over recent months rather than trusting the “was” price shown next to the sale. Inflating the reference price to exaggerate the advertised discount is common practice in this category, so a badge claiming 40% off might reflect a real savings closer to 10% once compared against the actual historical price.
Which smart home categories are actually worth waiting for a sale?
Higher-priced, competitive categories: security cameras, video doorbells, smart locks, and robot vacuums see the deepest real-dollar discounts, since brands compete hard on price during major sale events. Cheap year-round items like plugs, bulbs, and sensors see smaller absolute savings even when the percentage looks larger, so there’s less reason to hold out for a sale on those.
Should I buy a smart home bundle deal or individual items?
Check the math before assuming a bundle is the better deal. Bundles often pair a genuinely discounted item with one or two you don’t actually need, priced to look like a bigger combined savings than buying just the item you want on its own. Comparing the standalone item’s sale price against the per-item bundle price takes a minute and often changes the answer.
What’s the best way to shop these sales without overspending?
Shortlist two or three specific devices you actually want before the sale starts, check each one’s real price history so you know your target price in advance, and set a total budget beforehand. Deep discounts on things you weren’t planning to buy are the main way sale-season budgets get blown, not the planned purchases.
