Dreo Smart Humidifier 524S

Compiled by SmartHomeWorkflow Research · Dreo · Indoor Air & Comfort · ~$69.99 ($69.99 in Dreo's own US storefront product data on 2026-09-21, and the colour no longer changes what you pay. ⚠ THIS MOVED, AND IT MOVED IN BOTH THE FIGURE AND THE SHAPE. In August the Black variant was $62.99 while White, Blue and Grey were all $69.99, so the headline was the cheapest buyable swatch and choosing White cost $7.00 more for the same machine. Today all four variants — Black 10-16004-101, White 10-16004-111, Blue 10-16004-153 and Grey 10-16004-182 — are priced at $69.99 with no comparison price on any of them. Black has gone up $7.00 and the per-colour spread is gone: there is now one price for the product. Black and White are marked available; Blue and Grey are marked unavailable, as they already were in August, so two of the four colours are still not buyable. Recorded from the storefront's own machine-readable product record rather than the rendered page, because the rendered page shows one price at a time depending on the selected swatch. ⚠ A stale-fact catch worth keeping on the record, because it has now happened twice on this product: this catalogue's own research note from 2026-08-03 banked '$69.99 sale', the 2026-08-06 read found $62.99 on one variant and $69.99 on another, and the 2026-09-21 read finds $69.99 flat. The number on this listing has moved three times in seven weeks. It is re-verified every time rather than trusted, which is the only reason the record has been right each time.)

Before you buy

What do you need to make it work?

No hub for the device alone

Choose a platform above for its connection. A hub can be optional for the device itself and required for a platform or automation.

No hub. Dreo names none, and the control story on its own page is a direct one: the machine joins your Wi-Fi, the DREO app controls it, and Amazon Alexa and Google Home are reached from there. There is no Dreo bridge, gateway or base station in the product line at all, so there is nothing extra to buy. ⚠ The one thing Dreo does not tell you is the band. The page's specification block carries the entry 'Standard: Smart WiFi', which is the only place the radio is named anywhere on the page — it is a label, not a specification, and it states no frequency. Nearly every appliance in this class is 2.4 GHz only, and a household running a single merged Wi-Fi network with 5 GHz preferred sometimes has to split the band or use a guest network to get such a device onto the network at all. Dreo publishes nothing on this point, and this record does not guess at it.[2][11]

One device can provide more than one role. These are setup requirements, not a shopping list of separate purchases.

Setup and sources

Apple Home

Unknown, and the reason is a silence rather than a refusal. Dreo's product page names exactly two smart-home platforms, Alexa and Google Home, and Apple Home, HomeKit, Siri and Matter appear nowhere on it. That is not the same as Dreo publishing a platform list that excludes Apple, which is the bar we set before recording a firm no — the sentence reads like marketing copy naming the two biggest assistants, not like a complete statement of support. ⚠ Worth stating because it is a trap we have now hit twice in one week: 'Apple' DOES appear on this page, in the checkout badge row as Apple Pay, sitting beside Google Pay. A payment badge is not a smart-home integration, and we rated nothing here from one. We found no Apple-side documentation naming this machine, and Dreo seeks no Matter certification, so there is no standards route to inherit either.[2]

Google Home

Dreo lists Google Home beside its own app for this humidifier. It does not say how the humidifier connects to Google Home or what Google Home can do with it, so even on/off is unconfirmed there. Dreo describes its Auto Mode, which holds humidity within ±5%, as a feature of the machine and the app.[2][10][11][17]

Alexa

Dreo lists Amazon Alexa beside its own app for this humidifier. It does not say how the humidifier connects to Alexa or what Alexa can do with it, so even on/off is unconfirmed there. Dreo describes its Auto Mode, which holds humidity within ±5%, as a feature of the machine and the app.[2][10][11][17]

SmartThings

Unknown. SmartThings appears nowhere on Dreo's page, and no Samsung-side documentation naming this machine was located. The same reasoning as the Apple cell applies: a two-platform marketing sentence is not a published platform list, so silence here is genuinely silence rather than evidence of absence. A cloud-to-cloud route would be the only plausible shape given the machine has no radio but Wi-Fi and no Matter certification, and nobody on either side has published that one exists.[2]

Home Assistant

Unknown, because Home Assistant itself has not published an answer: it lists no Dreo integration, and the page one would live at did not exist when we checked on 2026-10-03. Dreo does publish its own Home Assistant add-on, linked from its support site as 'Official Home Assistant plugins on GitHub' and maintained by Dreo's engineering team, but its lists of supported and tested models do not name the 524S or the HM524S. The one humidifier it names is the Evaporative Cooler 712S. The add-on also says nearly every Dreo model has been integrated and that its tables are not exhaustive, which is not the same as naming this one, so it does not settle anything for this humidifier. It is added to Home Assistant by hand, signs in with your Dreo account and works through Dreo's cloud.[3][13]

Plans and ongoing costs[2][10][11]

✓ Works without a subscription: Yes.

Vendor account required: Not established — we have not sourced this yet.

No subscription and no paywall of any kind appears on the product page or anywhere in Dreo's own navigation for this machine. Recorded as an absence rather than a positive 'none', because Dreo nowhere states in writing that the app is free — the same standard applied to the SwitchBot humidifier in this subcategory. ⚠ Two things in Dreo's site navigation should not be mistaken for a subscription on this product: a 'Membership Program' with its own terms page, and a 'Manage Subscription' style account area. Neither is attached to the humidifier's function, and nothing on the product page gates a feature behind either. The only recurring cost that is genuinely attached to the machine is a consumable — Dreo sells 'Mineral Absorption Pads for Humidifiers - 16-Pack' at $9.99, listed on this product's own page.

Maintenance and offline use[2][3]

The catch

The first thing to know is that the price on this listing moves, and it has moved three times in seven weeks. On 2026-09-21 all four colours are $69.99 — Black and White buyable, Blue and Grey listed but unavailable — so the colour no longer changes what you pay. That is a change: the previous read on 2026-08-06 had Black at $62.99 against $69.99 for the others, a $7.00 difference for the same machine. Whichever way it sits when you look, check the price on the variant you actually intend to buy rather than the headline figure. Second, the platform story is short and it is worth reading literally. Dreo names two ecosystems, in one sentence, once: 'Compatible with DREO app, Google Home, and Amazon Alexa.' Apple Home, HomeKit, Siri, SmartThings, Matter and Home Assistant appear nowhere on the page. If you are an Apple Home household this is the sentence that matters, and Dreo has not written the one you want. Third, and this is the general trap in this whole category rather than a Dreo failing: 'compatible with Alexa' tells you a connection exists and nothing about what travels over it. A humidifier's genuinely useful remote controls are a humidity target, a live humidity reading and a tank-empty warning, and no vendor in this subcategory publishes which of those reach a voice assistant. The feature Dreo leads with — an Auto Mode it says holds humidity within ±5% — is described as a machine and app capability, never as something you can set by voice. Fourth, the radio is named but not specified. The spec block says 'Smart WiFi' and stops there; no band is stated. Appliances in this class are almost always 2.4 GHz only, and if your router merges both bands under one name you may have to split them to get the machine online. Dreo publishes nothing on this, so plan for the possibility rather than assuming it away. Finally, the ordinary stuff is good for the money: a 6 L tank, up to 60 hours between refills, 28 dB at its quietest, 500 square feet of stated coverage, top-fill, an aroma diffuser, and a humidity indicator light that changes colour with the room. The consumable is a mineral absorption pad at $9.99 for sixteen — cheap, and with no published replacement interval to tell you how long sixteen lasts.

Who it's for

This suits an Alexa or Google Home household that wants a large-tank humidifier for a bedroom or a living room and does not need the ecosystem to do anything clever with it — turn it on, turn it off, and otherwise let its Auto Mode hold the humidity while the DREO app handles the settings. At $69.99 — one price across all four colours as of 2026-09-21, up from the $62.99 the Black variant carried in August — it is still among the cheapest machines in this subcategory, and the 6 L tank and 60-hour runtime are the numbers you are paying for: fewer refills than almost anything near the price. Think carefully if you are an Apple Home household. Dreo names Alexa and Google Home and names nothing else, so there is no published Apple route, no Matter certification to fall back on, and no HomeKit bridge in the product line. Think carefully too if you run Home Assistant and expect local control: there is no official integration, so nothing here is documented as working locally, and the machine's remote control is a vendor cloud by every published account. And if the reason you want a smart humidifier is to say 'set humidity to 45%' out loud, understand that no vendor in this subcategory — Dreo included — publishes whether that specific instruction survives the trip into a voice assistant.
