The Matter mini is cheaper, fits a double socket, and looks tidy on a patio table until rain hits an unrated indoor shell. This page settles outdoor HomeKit smart plug IP44 versus indoor mini plugs: when the meross outdoor block is the right buy, and when every mini in this comparison must stay inside. The [HomeKit socket comparison](/hub/sockets-and-extension-leads/homekit-socket) holds the rows from 20 October 2026. We used those listings and UK product-safety framing.

The indoor plugs have to stay inside
The meross MSS315 packs and the Amazon Basics Matter plug have no IP rating in these listings. The four-pack listing asks about outdoor use and does not answer. Treat that silence as a ban. The THIRDREALITY Zigbee four-pack is likewise unrated for weather. BG and Lightwave are fitted indoor faceplates, not porch blocks.
The only outdoor row is the meross outdoor plug, MSS620HK-UK, at about £39.99 with 4.2 from 474 reviews. It is a black twin Type G block, about 15 × 8 × 5 cm, 13 A at 240 V, with a two-year warranty on the listing. The protocol is HomeKit Wi-Fi, not Matter. Energy monitoring is not stated. Weight on file conflicts at 520 g and 429 g. A cheaper sibling outdoor listing in search is not this row.
What IP44 and the cover actually mean
IP44 here means splash protection with the socket covers closed, not immersion and not a jet wash. Cover a socket when it is not in use, avoid prolonged extreme weather, and unplug the appliance and close the cover if the block will sit idle. Reviewers report boxes marked IP64 while the unit says IP44. This comparison uses IP44. Do not upgrade the rating from the box.
The same listing bans pumps. UK reviews often distrust the flaps alone in direct rain and add further cover. Some call the mains lead too short. Any extension still has to suit the outdoor location. A dry indoor lead is not weatherproofing. Trailing the block from an indoor socket through an open window does not make that socket outdoor-rated. A new outdoor circuit, rather than a plug-in on an existing outdoor point, is electrician work under Part P in England and Wales.
Power and Wi-Fi at the garden socket
The outdoor block is rated 13 A. The listing does not print a watt figure. A rule of thumb for a UK plug is about 3,000 W at 230 V. Do not invent 3,120 W for this listing. One block is not several high-draw tools. Do not daisy-chain it for a heavy load. The listing examples include lamps and a grill. A patio heater above 13 A is out, and a pressure washer or pump sits outside the listing’s own ban.
Wi-Fi is 2.4 GHz only. A chipset line claims longer range than most rivals and does not state metres. If the shed socket is outside your 2.4 GHz footprint, the IP line will not make it reliable. This page does not name a mesh product as a fix. Test the signal at the socket before you automate lights you cannot reach in the rain.
HomeKit outside is still a home-hub job
The outdoor row is native HomeKit Wi-Fi. Remote control needs an extra Apple device. The line names an iPad, HomePod or Apple TV. Current Apple guidance no longer treats an iPad as a supported home hub. Prefer a HomePod, HomePod mini or Apple TV left powered at home. Pairing taps are on the HomeKit socket set-up page. Do not buy this block expecting a Matter QR multipack.
Buy it when you already have a suitable outdoor socket, the load is lights within 13 A, you can close the covers, and 2.4 GHz reaches the wall. Keep every mini indoors. If the signal or the load fails those checks, leave the garden job alone. The checklist before either form is on the HomeKit socket buying guide.
Common questions
Can the Amazon Basics or meross mini plug live in the garden?
No. The Amazon Basics plug and the meross minis have no IP rating in these listings. The four-pack listing asks about outdoor use and does not answer. Treat that silence as a ban. Use the meross IP44 outdoor block, or keep the load inside.
What does IP44 allow, and what must the cover do?
Splash protection with covers closed, not immersion and not a jet wash. Fit the cover whenever a socket is unused, and do not treat open flaps as weatherproof. Avoid prolonged extreme weather, and close the cover if the block will sit idle.
The box says IP64 and the unit says IP44. Which rating do we use?
IP44. Reviewers report boxes marked IP64 while the unit says IP44. This comparison follows the unit and the listing, not the packaging anecdote. Do not upgrade the rating from the box text. Splash protection still assumes the covers are closed.
Will the outdoor block reach a shed on 2.4 GHz?
Only if 2.4 GHz already reaches that socket. The listing claims stronger range and fewer drop-outs than most rivals, and it does not give metres. Test on site before you rely on automations for lights you cannot reach in the rain.
Is 13 A enough for a patio heater or a pressure washer, and why does the listing ban a pump?
Stay inside 13 A and the listing’s own exclusions. Pumps are banned on the page. A heater above that rating is out. The listing does not print a watt figure, so do not invent one. Do not daisy-chain the block for a heavy load.
Is this outdoor plug Matter, or native HomeKit Wi-Fi?
Native HomeKit Wi-Fi. It pairs with a HomeKit code, not a Matter QR, and energy monitoring is not stated. It is not the Matter multipack path used by the indoor MSS315 rows. Do not buy it expecting a Matter share story.
Do I still need a home hub outside?
For away-from-home control and automations, yes. Leave a supported Apple home hub powered indoors, such as a HomePod, HomePod mini or Apple TV. Local success on the patio does not prove remote control. Do not use an iPad as the hub.
Can I plug this block into an indoor socket and trail it out of a window?
That bypasses a proper outdoor supply. The block’s IP44 claim does not make the indoor socket or the cable run outdoor-rated. Prefer an existing outdoor-rated point, or call an electrician for a new circuit in England and Wales under Part P.
