Compatibility

EcosystemSupportThe catch
Apple HomeWorksWorks with this ecosystemNative HomeKit — a real accessory in the Home app with Siri and CarPlay, not a cloud bridge, and the clearest single answer to Chamberlain having removed HomeKit from myQ. BUT YOU CAN BUY THE WRONG BOX, and this is the most consequential purchasing trap in the record: Meross also makes a NON-HomeKit MSG100, sold on Amazon under a near-identical listing explicitly titled '(Non HomeKit Versions)'. Every SKU on Meross's own store carries an HK suffix, so buying direct is safe; buying on Amazon requires reading the variant title carefully. A buyer choosing this product specifically to escape myQ's HomeKit removal can end up with a box that has no HomeKit at all. Remote access additionally needs an Apple home hub, which is Apple's requirement rather than Meross's.
Amazon AlexaWorksWorks with this ecosystemWorks through Meross's servers talking to Amazon's. Two things to know. Amazon requires a spoken voice PIN to OPEN a garage door while closing is unrestricted — that is Alexa's rule for garage doors, not a Meross limitation, and it is a safety feature rather than a defect. And because the connection runs between two companies' servers, it stops working when your internet does.
Google HomeWorksWorks with this ecosystemWorks through cloud-to-cloud account linking. As with Alexa, Google requires secondary user verification — a PIN — before opening a garage door by voice, per Google's own developer documentation, while closing needs none. Cloud-routed, so it fails in an internet outage.
SmartThingsPartialPartial support — see the catchAn official cloud-to-cloud linked service exists, but state synchronisation is chronically unreliable and has been for years. If the door is moved by anything other than SmartThings — the wall button, a remote, the Meross app — SmartThings frequently fails to update, which silently breaks any automation keyed to door state. SmartThings support has attributed it to expired callback tokens, and the fix is to unlink and relink, which destroys your existing automations. Reports run from 2023 through February 2026 with no resolution. ALSO DO NOT GENERALISE ACROSS THE FAMILY: Meross claims SmartThings for the MSG100 but not in the MSG150's copy.
Home AssistantPartialPartial support — see the catch[8]There is NO official Home Assistant integration — the page one would live at does not exist, and 'meross' appears nowhere in Home Assistant's own code. Meross never mentions Home Assistant in its own materials either, so nothing here is a route the maker supports. The community option, krahabb's meross_lan, is well maintained and genuinely runs on your own network, presenting the MSG100 and MSG200 as a garage door. Two catches: even that local route needs a device key taken from your Meross account, so it is not server-free to set up; and the rival community project is server-only, with its own maintainer warning that Meross throttles heavy users. We call it partial because a well-supported community project is not a supported integration.

Protocols: WIFI[7]

Needs before it works: No hub or bridge — the device joins 2.4 GHz Wi-Fi directly (2.4 GHz only, no 5 GHz) and HomeKit pairing is native rather than cloud-bridged. ONE CAVEAT THAT IS APPLE'S RULE, NOT MEROSS'S: remote HomeKit access requires an Apple home hub (HomePod or Apple TV), which Meross states in its own FAQ — 'the Home app can NOT control your device remotely unless you set up a Home Hub in your home as required by Apple.' Note also that the genuinely local Home Assistant path still requires a device key extracted from your Meross cloud account, so 'no hub needed' is true while 'no cloud needed' is not.

Subscription reality

✓ Works without a subscription: Yes.

Vendor account required: Not established — we have not sourced this yet.

No subscription of any kind — Meross states plainly on its product pages, 'No monthly fee or any other subscription fee!' and no feature was found gated behind a paid tier. This is the core of the anti-myQ pitch and it holds up on inspection. The only money beyond the device is the RGR551C adapter, which Meross's support documentation says it will ship free on request with proof of purchase, but which it simultaneously sells for $13.99 — see the adapter note in theCatch.

Maintenance reality

Security updates[20]

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.

Verified absence. Meross publishes no security-update period, end-of-support policy or lifecycle statement on its security page, and its only update-related content announces one firmware release rather than a duration. This is a garage door opener, which is the category where that absence costs a buyer most: the device physically opens a door, and its maker states no horizon for patching it. We record it as a checked absence rather than an unanswered question so the page can say that plainly. One route we could not walk: Meross's shop refuses our reader, and is recorded as refusing.

The catch

If you own a yellow-learn-button Chamberlain, LiftMaster or Craftsman opener — Security+ 2.0, which is most of what those brands sold between 2011 and 2022, and therefore exactly the myQ-refugee population this product is aimed at — the MSG100 and MSG200 do not wire to your opener at all. Those openers use a digital serial protocol on the wall-button terminals, so shorting them does nothing, and Meross's compatibility checker responds to a yellow learn button with 'You need an accessory to continue configuration'. That accessory, the RGR551C, is described in Meross's own FAQ as 'a universal remote with an extra signal cable soldered on it' — you pair a remote to your opener and the Meross unit presses one of its buttons for you. That works, but it is a materially more fragile architecture than a wired connection, and none of it is surfaced at the point of sale. Two ways out: the MSG150 at $62.99 handles Security+ 2.0 natively with no adapter, and if your learn button is purple, red or orange you can use the MSG100 directly. If your learn button is WHITE — Security+ 3.0, from November 2025 — no Meross model works at all. The other soft spot is safety on paper: the audible alarm is optional and user-disableable, Meross's own setting describes it as sounding 'when door is closing' rather than before the door moves, no visual warning is documented anywhere, no UL 325 claim is made, and the manual contains no entrapment warning despite remote closing being the entire purpose of the product.

Who it's for

Apple Home households wanting native HomeKit garage control with no subscription — buy the HK SKU, and buy it from Meross rather than guessing on Amazon. The cleanest install is a purple, red or orange learn button, or any non-Chamberlain opener that passes Meross's terminal-short test, because those wire directly with no adapter. If you have a yellow-button Chamberlain, LiftMaster or Craftsman, the MSG150 at $62.99 is the model to buy — it skips the adapter and the sensor entirely. The MSG200HK covers up to three doors on one device. Home Assistant users get real local control through the community meross_lan integration, with the caveat that setup still touches the Meross cloud for a device key. It is the wrong buy for anyone with a white learn button, since no model works; for anyone who wants Matter, which none of these have; for anyone building SmartThings automations keyed to door state, given a three-year-old unresolved sync defect; for anyone who needs a documented audible-and-visual warning before an unattended close; and for anyone shopping Amazon without checking for the non-HomeKit variant, which defeats the whole reason to choose this over myQ.

Meross's own MSG150 copy positions it as brand-specific ('Works with Chamberlain, LiftMaster, and Craftsman. For other brands, please check out Meross MSG100HK'), which establishes coexistence rather than succession.

  3. [3] A non-HomeKit MSG100 is sold on Amazon under a listing whose title reads, verbatim on 2026-08-08: 'meross Smart WiFi Garage Door Opener Remote Work with Alexa and Google | Compatible with SmartThings, App and Voice Control, Auto Close, Easy to install, No Hub Needed, Non-HomeKit Version'. The listing body names the MSG100. Recorded prominently because the buyer most likely to choose this product is one escaping myQ's HomeKit removal, and that is precisely the buyer the near-identical listing harms. ⚠ CORRECTION 2026-08-08: this entry previously also asserted that 'Meross also lists an MSG100 (Non-HomeKit Version) on its own store'. THAT IS NOT SUPPORTED TODAY. Three differently-constructed searches, each with the instrument proven live: (1) a scan of all 57 products in shop.meross.com/products.json found MSG100 only as MSG100HK-US, MSG100HKNW-EU/UK/AU and an MSG100-S-UN sensor cable — no non-HK opener; (2) the store's own search endpoint returned 16 results for 'non-homekit' and rendered the garage collection, listing only 'Meross Smart Garage Door Opener, MSG100' at the HK SKU; (3) the MSG100 product page itself contains no occurrence of 'Non-HomeKit', 'Non HomeKit' or 'without HomeKit'. Meross's own store sells the HomeKit model only. The previous quotation of the listing title was also inexact ('(Non HomeKit Versions)') and is replaced above with the verbatim current title. 🔴 WHY THIS AMAZON CITATION IS KEPT RATHER THAN RE-SOURCED, which is BQ-110's closing finding: the claim is not a manufacturer fact that happens to be cited to a retailer — it is a fact ABOUT THE AMAZON LISTING ITSELF, namely that a near-identical non-HomeKit unit is sold there under a confusable name. Amazon is the primary source for what Amazon sells, and no manufacturer page, certification registry or CPSC record can substitute for it. Re-sourcing this elsewhere would not be an improvement; it would be a worse citation for the same claim. — retailer-page research with a controlled manufacturer-store absence check, verified 2026-08-08

  4. [4] Meross's compatibility checker at meross.com/en-gc/mTerminal/compatibility-check/garage-door-opener was driven programmatically; selecting the YELLOW learn button returns verbatim 'You need an accessory to continue configuration, please Tap Here to Claim the Accessory'. Meross FAQ 257 and FAQ 405 describe the RGR551C accessory as 'a universal remote with an extra signal cable soldered on it', with instructions to 'Press the yellow learn button on your ceiling opener once' and noting 'The wires connect to the bottom right button, so only this button is working'. So on Security+ 2.0 the device does not communicate with the opener at all — it actuates a paired remote. COUNTERPARTY CONFIRMATION that yellow means Security+ 2.0: support.chamberlaingroup.com/s/article/Determine-the-Color-of-the-Learn-Button-on-Your-Garage-Door-Opener gives Yellow (round) = 'Security+ 2.0 (Rolling Code)', 310/315/390 MHz, 2011–2022. — vendor-tool and counterparty-source research, verified 2026-07-19
  5. [5] Meross support text says it will ship the proper accessory free on request, requiring an order number or receipt plus opener brand, model, learn-button colour and delivery address. But FAQ 405 itself does not state it is free, and Meross simultaneously sells RGR551C-ACCESSORY for $13.99 in its own accessories store (available:true, verified 2026-07-19). Recorded as: free on claim with proof of purchase per support docs, $13.99 if bought outright. — vendor-page research, verified 2026-07-19

  7. [7] csa-iot.org/csa-iot_products/?p_keywords=meross was driven in a real browser and paginated through all 6 pages, extracting every result row: 69 certificates across exactly 3 products — Smart Roller Shutter Switch (17), Smart Power Strip (25), Smart Plug Mini (27). Zero garage products, zero MSG-series products. The keyword matches the company field 'Chengdu Meross Technology Co., Ltd.', so this captures the full Matter portfolio. An initial filtered query was correctly distrusted and re-run unfiltered. STRUCTURAL CORROBORATION: the registry's own Device Type filter list was read in full and contains Door Lock, Door Lock Controller, Window Covering, Window Covering Controller and Shade Controller, but NO garage door device type — so at the time of this sweep a Matter-certified garage controller from any vendor had nowhere to certify to under the device types this registry exposes.

  8. [8] home-assistant.io/integrations/meross/ returns HTTP 404, and 'meross' is absent from all components in the home-assistant/core source tree — a stronger check than reading the rendered integrations index, which is client-side. The community option github.com/krahabb/meross_lan (728 stars, v5.8.0 February 2026) declares iot_class local_polling and exposes MSG100/MSG200 as a cover with DeviceClass.GARAGE. The alternative github.com/albertogeniola/meross-homeassistant (849 stars) is cloud-only and its maintainer warns that Meross throttles high-rate API users and imposes MQTT limits above roughly 10 devices; its fully-local broker addon has been dormant since December 2024.

  10. [10] Meross's Advanced Settings expose a toggle labelled verbatim 'Closing alarm: Sound alarm when door is closing' — concurrent with motion rather than before it, with no documented warning period or duration, and user-disableable. Whether it defaults on or off is UNKNOWN, and whether it fires on a TIMER-triggered auto-close is NOT documented, which is a real gap for an unattended operation. No visual or flashing warning is documented anywhere: the manual's LED table assigns every LED state to connectivity or sensor events and none to a closing warning, which is meaningful negative evidence. Certifications claimed are 'FCC, IC, ETL, CE, RoHS, WEEE' — ETL is Intertek's general product-safety mark and must not be read as UL 325 unattended-operation compliance. There is NO UL mark and no UL 325 claim, and the manual's safety text is generic electrical boilerplate with no warning about remote or unattended closing and no entrapment warning. — vendor-documentation research; explicit negatives recorded, verified 2026-07-19
  11. [11] shengrikuaile.com and mgahv.in both assert that the MSG200HK 'does not meet UL 325 standards for unattended operation'. Both were rejected as sources: they are wholesale scraped republications of Wirecutter content on unrelated domains, carrying identical URL slugs that confirm a common scrape. The underlying claim may well be true, but it is not citable from these, and the defensible primary-sourced fact is recorded instead — that Meross makes no UL 325 claim, documents no visual alarm, and documents no pre-motion warning period. Recorded explicitly so a later pass does not re-litigate it or mistake the scraped version for a source. — source-quality audit, verified 2026-07-19

  13. [13] The MSG200HK page markets 'The built-in sound alarm makes closing the door safer, especially for families with children and pets' while the documented feature is an optional, disableable toggle sounding concurrent with motion, with no visual component — the sharpest marketing-versus-documentation gap in the line. The alarm is promoted on the MSG200HK page, absent from the MSG100 page despite the MSG100 manual documenting it, and unmentioned for the MSG150. SmartThings is claimed for the MSG100 but absent from MSG150 copy while Meross's corporate 'Our Story' makes a blanket company-level SmartThings claim. Offline capability is claimed in marketing and absent from the manual. And 'Broader Compatibility' on the MSG150 in fact means narrower — three brands only. — vendor-page research, verified 2026-07-19
