⚠ Similar names, different products: Meross sells non-HomeKit variants of this outdoor plug under near-identical names, and only the HK-suffixed SKUs carry HomeKit. This page covers the MSS620BHK specifically — check for the HK in the model string, not the product title.
Exactly which product this is[1]
- Model number
- MSS620BHK (US/CA version; sold as MSS620BHK-US)
- Generation
- Not established
- Region this page covers
- US/CA
- Also sold or listed as
- Meross Outdoor Smart Plug MSS620 · MSS620BHK-US · Meross Outdoor Smart Plug with 2 Grounded Outlets
“Not established” means we have not sourced that detail yet — not that the product has no model number, generation or regional variant. We publish the gap rather than filling it.
Compatibility
| Ecosystem | Support | The catch |
|---|---|---|
| Apple Home | WorksWorks with this ecosystem[3] | Native HomeKit — a real accessory in the Home app with both sockets exposed individually, not a cloud bridge, and Meross states the product is listed on Apple's own HomeKit site. Remote access needs an Apple home hub, which is Apple's requirement. ⚠ BUY THE RIGHT BOX: Meross sells non-HomeKit variants of its plugs under near-identical names, and only the HK-suffixed SKUs carry HomeKit — this record covers MSS620BHK specifically. |
| Amazon Alexa | WorksWorks with this ecosystem[3] | Works through Meross's cloud-to-cloud skill, with each of the two sockets addressable by voice separately. Being cloud-routed, it stops working when your internet does — unlike the Apple Home path. |
| Google Home | WorksWorks with this ecosystem[3] | Cloud-to-cloud account linking, both sockets individually controllable. Same internet dependency as the Alexa cell. |
| SmartThings | InconclusiveWe researched this and the evidence doesn't settle it — the catch explains why[4] | Two Meross surfaces disagree and neither is decisive for this exact SKU, so this cell is left unknown rather than guessed. Meross's product site lists SmartThings among the ecosystems for the MSS620US variant; the US store's own MSS620BHK listing names Apple Siri, Amazon Alexa and Google Assistant and does NOT mention SmartThings. Our existing Meross record already documents that the company claims SmartThings for one model in a family and not another, so the family cannot be generalised across. |
| Home Assistant | PartialPartial support — see the catch[5] | There is NO official Home Assistant integration for Meross — home-assistant.io/integrations/meross_lan returns 404 and Meross never mentions Home Assistant in its own materials, so nothing here is a vendor-supported path. The community integration github.com/krahabb/meross_lan is well maintained and genuinely local, but even that route requires a device key extracted from your Meross cloud account, so it is not cloud-free to set up. Recorded as partial because a well-supported community integration is not a supported integration. |
? 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.
Protocols: WIFI[2]
Needs before it works: No hub or bridge — it joins 2.4 GHz Wi-Fi directly, and Meross states 'Works with the 2.4G Wi-Fi you already have. No hub required.' One caveat that is Apple's rule rather than Meross's: controlling it through Apple Home from outside the house needs an Apple home hub (HomePod or Apple TV), the same condition that applies to every HomeKit accessory.[2]
What it can do[10]
You can tell it to
- On/off
It reports
Not established — we could not confirm this from vendor documentation
Listed capabilities are what we could establish from vendor documentation. An ability missing here is unestablished — not necessarily absent.
Subscription reality[6]
✓ Works without a subscription: Yes.
Vendor account required: Not established — we have not sourced this yet.
Maintenance reality[1]
- Works without the internet: Partly — some of it keeps working and some of it does not. See the detail below.[3]
- IP44 — rated for rain and splashing, not immersion, and Meross names one exclusion explicitly: 'Do not use it for the pump.' Two grounded outlets, each switchable on its own. Certified FCC/ETL (control number 5012797) with a fire-retardant housing and overload protection. Cloud-dependent in normal use: Alexa and Google run cloud-to-cloud, and Meross states data is 'securely transmitted and stored using AWS and Apple servers in the US'. The Apple Home path is the local exception.
- 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.[9]
The catch
Wi-Fi only and largely cloud-routed: Apple Home is the one local path, while Alexa and Google go through Meross's cloud, so an internet outage takes voice control with it. And it was out of stock at Meross's own store when this page was researched.
Who it's for
For running two outdoor loads independently — Christmas lights on one socket, a patio lamp on the other — on a HomeKit-first setup, where the native Apple Home support and per-socket control are the real draw. Skip it if you want Matter or a local-first setup outside Apple Home, if you need better than IP44 (it is rain-rated, not submersible), or if you need it in hand this week.
