Meross Outdoor Smart Plug (2 Sockets) Review: Durable, HomeKit-Friendly Outdoor Control With a Fiddly 2.4GHz Setup
This IP44 outdoor plug with two independently controllable outlets is reliable, survives harsh winters and works locally with HomeKit, Alexa, Google and SmartThings, but pairing is 2.4GHz-only and can be fiddly, and it's rain-resistant rather than fully waterproof.
The Meross Outdoor Smart Plug (MSS620) provides two independently controllable outlets in a weatherproof (IP44) WiFi housing, and owners rate it well (a 4.4-star average). The strengths are consistent: solid integration with Apple HomeKit, Alexa, Google Home and SmartThings (Alexa commands run reliably within a couple of seconds), dependable performance over one to two years for many, and genuine durability, owners run it through Massachusetts winters and even -45C Canadian cold for outdoor Christmas lights. You get two separately nameable outlets (controllable individually or together), good WiFi range (one owner reaches it 150 feet away through several walls), and timers, schedules, countdowns and sun-based automations. HomeKit fans especially like that it can run fully locally through an Apple TV hub with no internet, even on an isolated VLAN, a privacy plus. The app is well made (with a widget, an option to disable the LEDs, and a direct link to the manual), and customer support is praised (they'll even recover a lost HomeKit code). The main drawbacks: setup is 2.4GHz WiFi only and can be fiddly, you often must temporarily disable your router's 5GHz/6GHz bands to pair, and the setup sequence matters (add to HomeKit first, then the Meross app). It's rain-resistant rather than fully waterproof, so it should be somewhat sheltered, the cord is short (around 3 inches), and HomeKit occasionally needs a re-pair (a power cycle fixes it). It has no Matter support or energy monitoring. For reliable, well-supported outdoor control, especially on HomeKit, it's a strong pick once you get past setup.
- Outdoor Christmas/holiday and yard lighting

- Cold-weather, long-range outdoor use
- Controlling two outdoor loads independently
Pros
- Reliable and durable (works through harsh winters); good WiFi range
- Strong HomeKit/Alexa/Google/SmartThings integration, including local no-internet HomeKit use
- Two independently controllable outlets; timers, schedules and sun-based automations
- Well-made app and excellent customer support
Cons
- 2.4GHz-only, fiddly setup (must temporarily disable 5GHz; sequence matters)

- No Matter support and no energy monitoring
Who is the Meross Outdoor Smart Plug (2 Sockets) for?
This is a weatherproof (IP44) outdoor WiFi plug with two independently controllable outlets, rated up to 1800W on 2.4GHz WiFi. It works with Apple HomeKit, Siri, Alexa, Google Assistant and SmartThings (no Matter), and has no energy monitoring. It's ideal for controlling outdoor lights and devices, holiday lighting, garden lights, water features, on schedules or by voice, and it's a particularly good fit for HomeKit users who want local (even internet-free) control. It's not for you if you need Matter, energy monitoring, a 5GHz connection, or a fully submersible/high-IP waterproof plug.
What buyers love
Reliability and integration lead. Owners run it dependably for one to two years, through harsh winters (Massachusetts snow, -45C Canadian cold), for outdoor Christmas lights and yard devices, and praise strong WiFi range (150 feet through walls for one owner). It works well across HomeKit, Alexa, Google and SmartThings, with fast, reliable voice control, and offers timers, schedules, countdowns and sun-based automations. HomeKit users especially value that it can be configured and run fully locally via an Apple TV hub, no internet required, even on an isolated VLAN, which appeals to the privacy-minded. The two outlets can be named and controlled independently or together, the app is well designed (widget, LED disable, manual link), the rubber caps and cable feel sturdy, and customer support is repeatedly praised (including recovering a lost HomeKit pairing code).
What to know before you buy
Setup is the main friction point. It's 2.4GHz WiFi only, so on modern mixed-band or mesh routers you typically must temporarily disable the 5GHz (and 6GHz) bands so your phone and the plug are on 2.4GHz during pairing. The setup sequence also matters, HomeKit users report success only when adding it to HomeKit first, then installing the Meross app, and those with isolated IoT VLANs need firewall rules to allow automations to reach the plug. Beyond setup: it's IP44 rain-resistant rather than fully waterproof, so keep it under a porch or otherwise sheltered from direct heavy weather; the cord is short (around 3 inches); and HomeKit may occasionally require a re-pair (roughly twice a year for one owner), which a quick power cycle resolves. A few units didn't work well with certain routers, some versions are rated lower (around 1250W/10A) than the listed 1800W, and there's no Matter support or energy monitoring.
Is the Meross Outdoor Smart Plug (2 Sockets) worth it?
Yes, for reliable outdoor smart control, particularly on HomeKit. It's durable (proven in extreme cold), integrates well with HomeKit, Alexa, Google and SmartThings, supports local internet-free operation, and is backed by good support and a solid app, earning its 4.4-star average. The reasons to be patient are the fiddly 2.4GHz-only setup (temporarily disabling 5GHz, following the right sequence), its rain-resistant (not fully waterproof) rating, the short cord, and no Matter or energy monitoring. If you want dependable, well-supported control of outdoor lights and devices and can push through setup, it's an easy recommendation, especially for Apple Home users; if you need Matter, energy data, or full waterproofing, look elsewhere.
Frequently asked questions
Why is setup tricky?
It connects to 2.4GHz WiFi only, so on modern mixed-band or mesh routers you usually have to temporarily disable the 5GHz (and 6GHz) bands so your phone and the plug are both on 2.4GHz during pairing. The sequence also matters, HomeKit users report adding it to HomeKit first, then the Meross app, works best. Once set up, it runs fine.
Is it fully waterproof?
It's IP44 rain-resistant, not fully waterproof or submersible. Owners run it outdoors successfully (including through snow and extreme cold), but recommend keeping it somewhat sheltered, under a porch or eave, rather than fully exposed to heavy driving rain. The rubber outlet caps help, but it's designed for splash/rain protection, not immersion.
Does it work with Apple HomeKit locally, without internet?
Yes, and HomeKit users specifically praise this. It can be configured and run entirely through an Apple TV hub without an internet connection, even on an isolated, restricted VLAN, which appeals to privacy-conscious owners. It also works with Alexa, Google Assistant and SmartThings, though not Matter.
Can I control each outlet separately?
Yes. The two outlets can be named and controlled independently, or grouped and controlled together as one device. Owners use names that sound distinctly different (for voice control) and set separate schedules, for example front-yard and back-yard lights on the same plug.
Is it reliable long-term?
Generally yes. Many owners report one to two years of dependable use, including through harsh winters, and some run multiple units nearly flawlessly. The occasional issue is a HomeKit connection that needs re-pairing (about twice a year for one owner), which a quick power cycle resolves. Customer support is also well regarded if you run into trouble.
