Nexx Smart Wi-Fi Garage Door Controller (NXG-300)

Compiled by SmartHomeWorkflow Research · Nexx · Garage & Access · ~$79.99 ($79.99 on the maker's own store, re-read 2026-08-13: available, and the store shows no struck-through original, so this is the list price and not a promotion. Unchanged since 2026-07-19. The two predecessor models named in the federal advisory, NXG-100B and NXG-200, are still sold out. The stored figure was a rounded $80 until 2026-08-13.)

⚠ Similar names, different products: Nexx and Nexxt are two unrelated companies, and the near-collision reaches every place a buyer would go to check this product. This device is made by SimpalTek, LLC under the Nexx name. Nexxt Solutions is a separate networking brand. In the US App Store the Nexx Home app (SimpalTek) sits beside 'Nexxt Home' (Software Brokers of America) and 'Nexx Smart Home' (Ojasvit Techno Private Limited), neither of which controls this product. It matters most in the security record: an NVD keyword search for 'Nexx' returns eighteen CVEs, and the ten most recent — the 2025 and 2026 entries — are Nexxt Solutions router vulnerabilities, not this vendor's. Anyone checking whether Nexx has new vulnerabilities will find some, and they will belong to somebody else.

Compatibility

Protocols: WIFI · BLUETOOTH^[8][12]

Needs before it works: No hub; the controller joins your 2.4 GHz Wi-Fi directly. Bluetooth is advertised on the product page as 'New Bluetooth connectivity', and the maker's blog claims the predecessor works over Bluetooth so you can control the door when the internet is out. Treat that claim as thinly documented: the quick-start guide filed with the FCC does not mention Bluetooth at all, and the maker publishes nothing about its range, whether it works only with a phone nearby, or whether it reports status as well as opening the door. All of that is unknown. Every ecosystem connection runs through the maker's cloud; no way to control it on your own network is documented.^[12]

What it can do^[24]

• Alexa: Nexx states plainly on its own product page that "Routines are not available due to Amazon Restrictions" — so Alexa can open, close and check the door by voice, and the door cannot participate in an Alexa Routine. Anyone planning "when I say goodnight, close the garage" needs a different path.

Listed capabilities are what we could establish from vendor documentation. An ability missing here is unestablished — not necessarily absent.

Subscription reality^[20]

✓ Works without a subscription: Yes.

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

No subscription was found for any function. Noted for completeness rather than as a selling point — the material facts about this product are in the security and safety sections below, not in its pricing model.

Maintenance reality^[16]

• Batteries: The controller is mains-powered. The wireless tilt sensor is battery-powered; no vendor battery-life figure was located.
• Works without the internet: Not established — we have not sourced this yet. It does not mean the product fails without the internet.
• Fully cloud-dependent. The maker's FAQ says the app 'communicates through the cloud with your Nexx devices', and no way to control it on your own network is documented. If the maker's cloud shut down, every app, voice, scheduling and remote function would stop, and no migration path is documented. The maker's 'Cloud Error Issue' support article prescribes fixing your timezone and logging in again, and never explains what survives an outage, so outage behaviour beyond the undocumented Bluetooth claim is unknown. The wall button and your existing remotes always keep working, which follows from how it is wired rather than from anything the maker says. Door position comes from a wireless tilt sensor stuck to the top of the door with Velcro, which the maker confirms 'detects up/down motion only': open or closed, with no in-between. An optional wired close-limit sensor also exists.

Security updates^[25]

Nexx 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.

Nexx publishes no security-support period, and on this model it publishes noticeably less than that. The product page carries no firmware, update or security statement of any kind. The support index is the more telling surface: it lists five products - Smart Alarm NXAL-100, Smart Garage NXG-200, Smart Garage NXG-100, Smart Plug NXPG-100 and Smart Garage Adapter NXAD-200 - and the NXG-300 this record describes is not among them, so the vendor's own support hub offers it no manuals, troubleshooting or compatibility pages. No regulatory declaration was found on any Nexx surface. Readers should weigh that against what this record already documents about the 2023 federal advisory affecting Nexx controllers: a manufacturer with an open advisory history that publishes no patching commitment leaves a buyer with nothing to hold it to.

The catch

There is an open United States government security advisory covering this product line, and the maker never engaged with it. CISA published the advisory on 4 April 2023, covering five vulnerabilities in Nexx devices. The most severe, rated 9.3 by CISA and 10 out of 10 by the national vulnerability database, was a set of universal built-in credentials that let a remote attacker open any customer's garage door with one request. The researcher first contacted Nexx on 4 January 2023 and received no reply before publishing three months later. Nexx did act afterwards: on 7 April 2023 it emailed customers announcing a security update by April 10 and said it had disabled the devices' internet connection to address the issue. What nobody has ever established is whether that fixed anything. CISA's advisory has never been revised and still reads 'Nexx has not responded to requests to work with CISA to mitigate these vulnerabilities.' All five vulnerabilities remain listed with no patch, no maker advisory and no fixed version. Nexx has published no security bulletin and no firmware changelog, and no researcher, journalist or agency has re-tested in the three years since. Two more facts a buyer should have: the built-in credentials were reported to live in both the firmware and the phone app, and the iPhone app has not been updated since December 2021, so no app update has ever removed them, though the server-side flaws could have been fixed silently. And the two other products named in that advisory, the Smart Plug and the Smart Alarm, are still listed for sale today; the two garage models CISA named are the two now sold out. None of this appears on the maker's site, which markets the product's encryption in superlative terms. Separately, and on a different axis: federal rules require an audible and visual warning before any unattended close, and Nexx publishes an official tutorial for switching its warning beep off, a mandatory safety function shipped as a user preference. No visual warning component is evidenced at all. The safety documentation has also gone backwards over the product line's life: the older NXG-100 manual carries a proper installation-warning page, and the NXG-200 and NXG-300 manuals dropped it, leaving a single generic line.

Who it's for

Anyone considering this needs to weigh one thing that no specification sheet carries: a federal advisory covering this product line remains open, the vendor is recorded in it as not having responded, no fix has ever been publicly confirmed by any independent party, and the vendor is still selling other products named in that same advisory. A buyer who is comfortable proceeding would need to be satisfied without any way to verify whether the unit they receive is remediated, because the vendor has published nothing that would let them check. On the functional side, setting the security question aside entirely: it is a cloud-dependent controller with no Apple Home support, no Home Assistant path, no Matter, an Alexa integration that cannot participate in Routines, and an iOS app frozen since 2021 at a 1.76-star rating. Households on Alexa or Google who want a straightforward cloud controller have several alternatives in this category at similar or lower prices without an open advisory attached. We are recording this product because the advisory is a documented public fact that a buyer will not find on the vendor's own pages, not because we have tested it.

1. [1] Retrieved in full from cisa.gov (WebFetch returned 403; a direct fetch succeeded), released 2023-04-04, covering NXG-100B and NXG-200 plus the Smart Plug and Smart Alarm. Five CVEs: CVE-2023-1748 (hard-coded credentials), CVE-2023-1749, CVE-2023-1750, CVE-2023-1751, CVE-2023-1752. CVE-2023-1748 is scored 9.3 by CISA and 10.0 at NVD — the two authorities differ and both figures are recorded rather than picking one. — regulator-source research, verified 2026-07-19
2. [2] Researcher Sam Sabetan's own writeup establishes first contact 2023-01-04 and public release 2023-04-04 with no reply at any point. CISA's advisory independently records that Nexx did not respond to coordination attempts. Both are primary to their respective authors. — researcher and regulator source research, verified 2026-07-19
3. [3] On 2023-04-07 Nexx emailed customers announcing 'a system update to the following product devices to enhance their security and performance: Nexx Garage (all models), Nexx Gate (all models), and Nexx Plug', rolling out that day and completing by 2023-04-10 'if not earlier', and stating 'We had to disable the device internet connection to address this issue'. VERIFICATION CHECKS, ALL NEGATIVE as of 2026-07-19: CISA's advisory shows only the 2023-04-04 release date with no Update A/B revision markers and its mitigations section still reads 'Nexx has not responded to requests to work with CISA to mitigate these vulnerabilities'; all five CVEs at NVD remain vulnStatus Modified, last modified 2026-06-17; reference tags on all five are only Third Party Advisory and US Government Resource, with no Patch and no Vendor Advisory tag; no CPE range on any of the five carries a versionEndExcluding, so NVD records no version at which the flaw ceases. No Nexx security bulletin or firmware changelog was found, and no independent re-test by any researcher, journalist or agency was found in three years. RECORDED DELIBERATELY as 'no confirmed fix' rather than 'unpatched', because asserting a remediated product was unpatched would be a serious error in the other direction. Note in fairness that CVE-2023-1749 through -1752 are server-side and could have been remediated silently. — regulator and NVD research; explicit fairness check, verified 2026-07-19

Legal entity SimpalTEK LLC confirmed via both app stores, FCC grantee code 2AN5L, and three registered trademarks. THIS CORRECTS THE BRIEF'S PREMISE: 'vendor abandonment' is too blunt — a company shipping Android builds in 2026 is not defunct. The accurate characterisation is selective neglect plus non-engagement: an active seller that maintains one platform, left the other frozen since before the vulnerabilities were reported, and never answered a researcher, a federal agency or the press.

5. [5] All THREE FCC-filed manuals were read directly — NXG-100 (2AN5LNXG-100R), NXG-200 (2AN5LNXG200) and NXG-300 (2AZD7NXG-300). A keyword sweep across all three for 'UL 325', '1211', 'audible', 'alarm', 'unattended', 'remote clos' and 'flash' returned zero substantive hits: no §1211.14(f) marking, no reference to 16 CFR 1211, and no documented audible-and-visual pre-close warning sequence. THE SHARPER FINDING, which is stronger than an absence: Nexx publishes an official tutorial titled 'Nexx Home App: Enable or Disable Garage Opener Beep Warning Sound' (March 2021), and its support material states the app 'allows you to choose if your garage door should play a warning sound when activated or not'. 16 CFR 1211 §1211.14 makes the warning MANDATORY, not a user preference — a warning shipped as a toggle the owner can switch off does not meet a mandatory requirement regardless of its default state. Warning hardware does exist (the manual documents pairing beeps: 2 entering pairing, 3 on success, one 2-second beep on failure), but NO visual warning component is evidenced anywhere — the only lights are Power, WiFi and Activity status LEDs on the unit body, inside the garage, which is not a warning lamp. A DOCUMENTATION REGRESSION worth recording: the OLDEST model has the MOST safety documentation. The NXG-100 manual carries a proper installation-warning page ('Nexx Garage and any door sensors are meant to be used with garage door openers that are equipped with photoelectric safety sensors (manufactured after 1993)' plus 'NEVER operate the remote access feature of your Nexx Garage without ensuring that it is safe to do so'), and the newer NXG-200 and NXG-300 manuals DROPPED that page entirely, leaving one line: 'SAFETY WARNING: Make sure the garage door does not get obstructed by any child, person, or object.' STATED WITHOUT OVERREACH: no teardown or firmware analysis was performed, so the beep's duration, its timing relative to door movement, and its default state are all UNKNOWN, and retail packaging was not photographed. This is a documented gap plus a documented defeatable control, NOT a finding of regulatory non-compliance. — regulatory-filing and vendor-documentation research; limits stated, verified 2026-07-19
6. [6] Two independent signals. FIRST, the FCC grantee changed: every earlier Nexx model was filed by SimpalTEK LLC itself (grantee code 2AN5L), while the NXG-300 was filed under 2AZD7 — CherryEmme Technologies Co. Ltd of Hong Kong, granted 2021-03-29 — which is the signature of moving from in-house design to a contract manufacturer. SECOND, and unambiguous: the NXG-300's own user manual repeatedly refers to the NXG-200, with step headings reading '6. CHECK STATUS OF NXG-200' and '7. ADD NXG-200 TO NEXX HOME'. It is the NXG-200 document with the title swapped and the body left uncorrected. The same manual contains mangled customer-facing links ('gotnexx.Bm/dwck', 'support@getnexx.Bm') that would not work if typed. PRACTICAL CONSEQUENCE FOR THE SECURITY QUESTION: the NXG-300 is the only garage model still purchasable and the only one NOT named in CISA's advisory — but if it is the NXG-200 design re-sourced to an ODM, its absence from the advisory is a technicality of enumeration rather than evidence it was ever fixed. All grant dates were verified against two independent sources (fccid.io and fcc.report) because fccid.io initially showed application and grant dates as identical. — regulatory-filing and vendor-manual research, verified 2026-07-19
7. [7] The Texas Comptroller's public Active Franchise Taxpayers dataset (data.texas.gov/resource/9cir-efmm.json, rows updated 2026-07-18) lists SIMPALTEK LLC with status A (Active) and right to transact business A (Active), taxpayer number 32060503383, charter date 2016-05-16, at an address matching the FCC grantee record exactly. Cloud infrastructure is up (api.nexxhome.com and home.nexxhome.com both return HTTP 200) and the store transacts. NO acquisition, bankruptcy, insolvency or discontinuation reporting was found. RECORDED EXPLICITLY BECAUSE 'DEFUNCT' WOULD BE FACTUALLY WRONG and indefensible. What the evidence supports instead is a single-maintainer skeleton operation: the Android app shipped 2026-01-26 while the iOS app has been untouched since 2021-12-03 at 1.8 stars; the YouTube channel linked in Nexx's own site footer is CONFIRMED DEAD ('This channel does not exist'); the Facebook page appears deleted, which is meaningful rather than a login wall because Facebook group content loaded un-authenticated in the same session; there is no phone support, only email; no BBB profile exists across three searches; and the parent's own domain simpaltek.com is a dead Shopify store. Also confirmed: the two garage models named in CISA's advisory (NXG-200, NXG-100B) now report available:false, while the Smart Plug NXPG-100 and Smart Alarm NXAL-100 — also named in that advisory — remain purchasable. — state-registry, app-store and infrastructure research; framing corrected, verified 2026-07-19

9. [9] From the FCC-filed NXG-300 quick-start guide: the compatibility test instructs the installer to 'put each end to the same terminals where your wall button wires are terminated to. By doing so, your garage door should activate', and installation is to 'twist together each wire of the wall button to each of Nexx's connection' with 'It does not matter which wires goes to which terminals'. So it is a momentary dry-contact relay wired in parallel with the existing wall button, polarity-agnostic. WHAT IS NOT ESTABLISHED: Nexx publishes NO statement anywhere naming Security+ 2.0, Security+ 3.0, learn-button colours or myQ, and its compatibility page is a dropdown lookup with no published static list. A Nexx adapter (NXAD-200) exists and the vendor states some openers 'will only work with Nexx Garage Adapter', which fits the pattern of digital-serial wall controls defeating a plain contact closure — but that reasoning is mechanism-level inference plus third-party adapter evidence, NOT a Nexx claim, and is flagged as such. — regulatory-filing research; inference flagged as inference, verified 2026-07-19

[10] Three queries against saferproducts.gov/RestWebServices/Recall — RecallTitle=Nexx, ProductName=Nexx and RecallDescription=Nexx — each returned an empty array, while a control query for ProductName=garage returned 8 records (Chamberlain myQ 2023, Loctek, Eagle, H.E., Genie, Lennox, Chamberlain 1997, Stanley 1991), none of them Nexx. So the negative is real. METHODOLOGY CAVEAT THAT SHOULD TRAVEL TO FUTURE RECORDS: this API's ManufacturerName parameter DOES NOT FILTER — it returned an identical 9,905-record dump for 'Nexx', for 'SimpalTEK', and for the nonsense control string 'ZZZZQQQQNOTREAL'. Any result obtained through that parameter is meaningless and must not be cited. Note also that the absence of a recall is NOT evidence of safety: a recall requires CPSC action, and consumer incident reports could not be checked because the CPSC public incident database exposes no REST endpoint. — regulator-API research with control and negative control, verified 2026-07-19

NO CNET review of this product could be found at all; the quote and the score appear invented. The same page presents a '7.8/10 Consensus' aggregated from '21 trusted sources including Wirecutter, CNET, PCMag, Consumer Reports', none of which could be verified as having reviewed it, and recommends the product in a 2026 buying guide with NO mention of the CISA advisory or the five CVEs — the single most decision-relevant fact about it. Also rejected: manuals.plus serves an NXG-300 'manual' page contaminated with a different product's content, listing All-O-Matic support contacts and describing RADIO/COMMON terminal wiring — the FCC filing was used instead.

26. [26] No source was read for this entry, deliberately. It records a classification so the classification is not silent: what was classified is evidence this record already carried — the integration catches and the citations already listed on this page — and this pass altered none of it. — absence-classification reading pass (doc 16 #453) — this record's own integration catches and the provenance entries claiming them, re-read against the 2026-08-22 classification; no vendor page fetched and no new research done, verified 2026-08-22

28. [28] Nexx, NXG-300 Smart Wi-Fi Garage Door Controller product page (https://getnexx.com/products/nexx-smart-wi-fi-garage-door-controller-nxg-300), read 2026-09-03 through tools/lib/gated-fetch.mjs (HTTP 200). The page publishes a "Works With" list, verbatim and in order: "iOS · Android · Bluetooth · Amazon Alexa · Google Home · Siri · SmartThings · IFTTT" — which names Google Home and SmartThings, and does NOT name Home Assistant. The feature copy states the voice scope, verbatim: "VOICE CONTROL Open, close, or monitor using Amazon Alexa, Google Assistant, or Apple Siri. * Routines are not available due to Amazon Restrictions." — vendor-page research (BQ-322 batch 5 — claim-coverage cells, first-party re-read through tools/lib/gated-fetch.mjs), verified 2026-09-03

The research trail that used to sit inside those fields is preserved here verbatim., verified 2026-09-05
