Meross Smart Wi-Fi Surge Protector Power Strip (MSS425FHK)
Compiled by SmartHomeWorkflow Research · Meross · Plugs & Outlets · ~$37.99 (At the time we researched it — read from Meross's own store data rather than from the page as it renders, shown as $37.99 against a $48.99 was-price, SKU MSS425FHK-US. Never treated as a live price. We did not read stock state from that source and deliberately claim nothing about it here.)
⚠ Similar names, different products: Meross ships this power strip in HomeKit and non-HomeKit variants whose product titles read almost identically, and the letters at the end of the model are the only reliable tell — this record covers the HK-suffixed MSS425FHK, and it is the HK that carries Apple HomeKit. The same family also varies by outlet and USB count across regions. Check the model string on the box rather than the listing title, which is the same mistake this catalogue already documents on the Meross MSS620 outdoor plug.
Compatibility at a glance
Does it work with your platform?
Choose your platform to see its setup and functions. Your choice carries across product pages.
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 or bridge is needed to use it — Meross states 'Works with any 2.4GHz or Dual Band WiFi router. No hub required.' The one condition is Apple's rather than Meross's, and Meross spells it out: 'To enable HomeKit remote control, a HomePod, an Apple TV 4K or Apple TV HD or an iPad is needed as a Homekit bridge to connect it to your home WiFi network.' Without one, Apple Home control works at home and not from away — and Meross names its own app as the alternative for that case.[1]

This shows the connection route, not every network cable or a shopping list. One device may provide several roles, including a Matter controller and a Thread border router. Only a Thread connection needs the Thread role. Read the equipment cards for all recorded requirements.

Native HomeKit rather than a cloud bridge, and Meross states the version floor itself: 'Compatible With Apple HomeKit(iOS 13 or above), Siri'. Each of the four AC outlets is individually controlled, so they appear as separate accessories; the four USB ports are group-controlled and are not four separate things in the Home app. Remote access needs an Apple home hub — Meross names 'a HomePod, an Apple TV 4K or Apple TV HD or an iPad' — which is Apple's requirement, not a Meross limitation. ⚠ Buy the HK model: Meross sells non-HomeKit variants of this strip under near-identical titles.[1]

Named directly by Meross in its voice-control line and reached by account linking through Meross's cloud, with each outlet addressable separately by voice. Being cloud-routed it stops working when your internet does — unlike the Apple Home path on the same device, which is the sharpest practical difference between the two on this product.[1]

Matter controller
Not a Matter device — this entry records the Apple home hub requirement, which is the only hub-shaped thing in the path. Meross names the qualifying devices itself: 'a HomePod, an Apple TV 4K or Apple TV HD or an iPad'. It is needed for Apple Home control from outside the house, not for local control and not for the Meross app.[1]
One device can provide more than one role. These are setup requirements, not a shopping list of separate purchases.

?InconclusiveWe researched this and the evidence doesn't settle it — the catch explains why[15][18]
Not established. Home Assistant ships no Meross integration and Meross names Home Assistant nowhere. A community project, meross_lan, lists the MSS425 and runs on your own network, but it needs a device key taken from your Meross account, and neither Meross nor Home Assistant stands behind it.
? Inconclusive means we researched that ecosystem and the evidence doesn’t settle it — the catch says why, and the sources are listed below. It is a statement about the available evidence, never a verdict on the product. A Setup Check researches your exact setup where the official sources don’t answer.
Vendor account required: Not established — we have not sourced this yet.
No plan, paid tier or recurring charge is named anywhere in Meross's own listing for this product, including around the scheduling, timer and sunrise/sunset features that would be the obvious things to gate. We record no subscription on that basis; the honest limit is that this is the absence of paywall language on the maker's own listing rather than an explicit 'no subscription' statement. A Meross account is needed for the Meross app, which is a different thing from a subscription and is recorded separately.
Works without the internet: Inconclusive — we read the vendor's own material and it does not answer this either way. It does not mean the product fails without the internet.
Four AC outlets and four USB ports, and the control granularity is uneven in a way that matters: '4 individually controlled Outlets and 4 group controlled USB ports' — so each socket is its own switch, while the USB ports move together as one. USB output is 'Up to 4.0A for four USB ports' shared. Electrical and safety as published: 'made of flame retardant PC material and has been approved for safety and quality assurance (ETL and FCC certificate) and it supports any home device up to 15A'. Cord length is in the listing title as a 1.8 m extension cord. Radio: 'Works with any 2.4GHz or Dual Band WiFi router' — the dual-band phrasing describes the router, not the device, and Meross's Wi-Fi devices in this family join 2.4 GHz. Regional fit is stated by the maker: 'Suitable for use in the USA, Canada, Mexico and other countries that use US-type plugs.' Scheduling includes sunrise and sunset triggers. It depends on Meross's servers, with the Apple path as the exception — the same shape we already recorded on the Meross outdoor plug: Alexa and Google run between Meross's service and theirs, and the Meross app's away-from-home control is explicitly a remote feature ('control home devices from anywhere anytime. No distance limitation'), while HomeKit control on your own network is not.
Security updates: Meross publishes no security-update support date for this model. That is a gap in what the manufacturer has published, not evidence either way — some makers declare a support period and some say nothing at all.[4][20]
The catch
The four AC outlets are individually switched and the four USB ports are not — they move as one group — so if the point of buying it is controlling a phone charger separately from a tablet charger, that is not what this does. It is Wi-Fi and largely cloud-routed: Apple Home is the one local path, while Alexa and Google Home run through Meross's cloud, so an internet outage takes both with them, and Meross does not say how SmartThings connects. Home Assistant has no official integration at all; the community route is real and local but needs a device key pulled out of a Meross cloud account first. And the model letters decide what you get — the HK suffix is what carries HomeKit, on a listing whose title looks the same either way. On the other side of the ledger: per-outlet control at this price, ETL and FCC certification, a 15 A rating, surge protection, and native HomeKit rather than a bridge.
Who it's for
A desk, media wall or bench where four things need switching independently — and especially an Apple Home household, since HomeKit is the one path on this strip that keeps working without the internet. It also suits a household that wants scheduling with sunrise and sunset triggers on individual sockets. Look elsewhere if you need the USB ports controlled separately from each other, if you want Matter, if you want a local-first setup outside Apple Home, or if you are on Home Assistant and unwilling to run a community integration that starts with extracting a key from the vendor's cloud.
