Best Smart Plug for a Dehumidifier in a Rented Flat
A dehumidifier that runs all day wastes power and fills its tank fast, and a renter cannot rewire the flat to fix that. A smart plug solves it from the socket: schedule the unit, cut it remotely, and keep the damp under control without touching the wiring. The five picks below cover budget multi-packs, a single-plug starter, and one model with energy monitoring. The overview table shows the short version; the reviews explain the fit.

1. Amazon Basics Smart Plug, 4-Pack
Type: Indoor smart plug, 4-pack
Voice Control: Alexa only
Connectivity: 2.4 GHz Wi-Fi
Hub Required: No
Design: Compact
Color: White
This four-pack is the value route into scheduled dehumidifier control. Each plug pairs over 2.4 GHz Wi-Fi with no hub, so a renter can drop one behind the unit in the bedroom and keep the spares for lamps or a bathroom fan. The compact body is sized to sit in a double socket without blocking the neighbour, which matters in small flats where outlets are scarce. Scheduling and remote app control handle the daily on-and-off cycle, and Alexa voice control covers the quick manual override.
The pack suits renters with more than one damp room, or anyone who wants to automate a few appliances at once rather than buy singles. It earns its place on price per plug and on the no-hub setup. The catch is the ecosystem: Alexa only means a Google Home or Apple household gets no voice control, and the app is basic next to the brand-name alternatives. The 2.4 GHz requirement is also a common trip-up on modern dual-band routers.
Trade-off: The low price per plug comes with Alexa-only voice control and a stripped-back app.
2. Kasa Smart Plug Ultra Mini 15A, EP10, 1-Pack
Type: Indoor smart plug, 1-pack
Voice Control: Alexa and Google Home
Connectivity: 2.4 GHz Wi-Fi
Hub Required: No
Rating: 15A
Design: Ultra mini
Color: White
Kasa Smart Plug Ultra Mini 15A, EP10, Smart Home Wi-Fi Outlet
The Ultra Mini is the single-plug answer for a flat with one dehumidifier and one awkward socket. Its ultra-mini shell leaves the second outlet usable, and the 15A rating covers the draw of a typical compressor dehumidifier without strain. Setup runs through the Kasa app over 2.4 GHz Wi-Fi with no hub, and the plug works with both Alexa and Google Home, so the household is not locked into one assistant. Scheduling, timers and remote toggling are all handled in the app.
This is the pick for a renter who wants one reliable plug and does not need spares. It earns its place on broad compatibility and a genuinely small footprint. The caution is simply that it is a single: buying four separately costs more than the multi-packs here, so a flat with several damp rooms should look at the four-pack instead.
Trade-off: Buying singles is the expensive way to cover more than one room.
3. Kasa Smart Plug HS103P4, 4-Pack
Type: Indoor smart plug, 4-pack
Voice Control: Alexa, Echo and Google Home
Connectivity: Wi-Fi
Hub Required: No
Rating: 15 Amp
Certification: UL certified
Control: Touch actuator
Color: White
This four-pack is the step up from the single Ultra Mini: same brand ecosystem, same 15A rating, but four plugs and a physical touch actuator on the body for manual switching without the app. UL certification is the reassurance a renter wants when an appliance runs unattended for hours in a bedroom. The plugs work with Alexa, Echo and Google Home over Wi-Fi with no hub, and the Kasa app handles schedules and away-from-home control.
It suits a renter running a dehumidifier plus a second unit, a fan or a heated airer across a small flat. It earns its place on certification and on the actuator, which is genuinely useful when the phone is elsewhere. The drawback is the older, chunkier body shape: it is not as slim as the Ultra Mini, so a tight double socket may lose its neighbour outlet.
Trade-off: The larger shell can block the second socket in a tight outlet.
4. GE Cync Smart Plug, Matter Compatible
Type: Indoor smart outlet, 1-pack
Voice Control: Alexa and Google Home
Connectivity: Wi-Fi
Hub Required: No
Platform: Matter compatible
Feature: Energy monitoring
Color: White
GE Cync Smart Plug, WiFi Outlet, Matter Compatible, Works Alexa & Google
The Cync plug is the pick for anyone who wants to know what the dehumidifier actually costs to run. Energy monitoring in the app shows consumption over time, which turns a vague worry about damp-climate electricity bills into a real figure. Matter compatibility means it can join a wider smart-home setup rather than sitting in its own app, and it works with Alexa and Google Home over Wi-Fi with no hub. Voice and app control cover the usual scheduling and remote toggling.
It suits a renter in a metered flat, or one already building a Matter-based setup across other devices. It earns its place on monitoring and on future-proofing. The caution is price and volume: this is a single plug at a premium over the budget singles, and its popularity is modest next to the Kasa and Amazon Basics packs, so a multi-room renter pays a lot for the monitoring feature.
Trade-off: Energy monitoring is useful, but a single plug at this price is poor value for covering several rooms.
5. GHome Smart Plug
Type: Indoor smart outlet
Voice Control: Alexa and Google Home
Connectivity: 2.4 GHz Wi-Fi only
Hub Required: No
Certification: ETL and FCC listed
Feature: Timer
Color: White
GHome Smart Plug, WiFi Smart Plugs that Work with Alexa and Google Home
The GHome plug is the cheapest route to a timed dehumidifier cycle. It connects over 2.4 GHz Wi-Fi with no hub, works with Alexa and Google Home, and carries ETL and FCC listing, which is the baseline safety paperwork a renter should expect from a budget plug. The timer and app remote control cover the core job: run the unit for a set window each day and switch it off remotely if plans change.
It suits a renter on the tightest budget, or one who wants a cheap second plug for a spare room. It earns its place on price and on the safety listings, which many cheap plugs lack. The drawback is the app: budget-brand apps tend to be plainer and less polished than Kasa or Cync, and there is no energy monitoring or Matter support here.
Trade-off: The lowest price buys a basic app and no monitoring or Matter support.
Before You Buy
- Compatibility: Check the assistant in the flat — Alexa-only plugs lock out Google Home and Apple households.
- Wi-Fi band: Every plug here needs 2.4 GHz; a dual-band router may need the 2.4 GHz band split out during setup.
- Socket space: Compact and ultra-mini bodies keep the second outlet usable; larger shells can block it.
- Rating: A 15A plug comfortably covers a typical dehumidifier; check the unit’s label before pairing.
- Certification: UL, ETL or FCC listing matters for an appliance left running unattended.
- Extras: Energy monitoring and Matter support cost more; decide whether either is worth it before paying.
- Quantity: Multi-packs beat singles on price per plug for a flat with several damp rooms.
Frequently Asked Questions
-
Can a smart plug run a dehumidifier safely?
Yes, provided the plug is rated for the unit’s draw. A 15A plug covers a standard dehumidifier; check the appliance label first. -
Does a smart plug need a hub in a rented flat?
None of the picks here need a hub. They connect directly over 2.4 GHz Wi-Fi, which suits a renter who cannot install extra hardware. -
Will a smart plug work with a dehumidifier that has a mechanical dial?
Only if the dial is left in the on position. The plug controls power to the unit, not its internal settings. -
Which pick suits a Google Home household?
The Kasa plugs, the GE Cync and the GHome all work with Google Home. The Amazon Basics pack is Alexa only. -
Is energy monitoring worth it for one dehumidifier?
It is if the flat is metered and the bill matters. Otherwise a cheaper plug with a schedule does the same job. -
Can the plug be removed at the end of a tenancy?
Yes. All five are plug-in units with no wiring, so they lift out and move to the next flat.
Bottom Line
For most renters, the Kasa Smart Plug HS103P4 four-pack is the best smart plug for a dehumidifier in a rented flat: UL certified, 15A rated, works with Alexa and Google Home, and covers several damp rooms for less than buying singles. A one-dehumidifier flat can drop to the Ultra Mini, and anyone who wants to track running costs should pay the premium for the GE Cync.
