Hi all,
I went through a lot of Amazon Black Friday and Cyber Monday smart home deals, checking every major brand I could think of. I compiled everything into tables for comparison, including the original price, the Black Friday deal price, and the discount percentage.
You can check it out here:
Just like every year (and for those who aren't aware), the discounts appear bigger than they actually are. First, because brands like to calculate based on the original recommended price and not the usual price a device sells for. And second, because they slowly raise prices in the months leading up to the sale (prime day included) to make the discounts appear bigger.
From all that data I gathered, the real number floats around 15-20% across all brands. It's still a discount, just not as big as most make it out to be. Robot vacuums have the biggest price drops, perhaps cause it’s a competitive segment and a good chance for brands to clear stock. From the other smart home brands, I think ThirdReality and Sonoff have the most honest discounts. They aren’t huge, but they’re the least manipulated. Lutron Caseta and Eve have the worst (and fakest) discounts, with most products actually priced higher than last year’s sale.
The easiest way to check how real a discount is, is to use a price history tool like Keepa. It adds a price graph directly onto each Amazon product page, showing the true historical price rather than the inflated deal price. CamelCamelCamel is another useful alternative to Keepa, but from my tests it appears to have less data on smart home products compared to Keepa.
