Hangzhou BroadLink Technology — 9 prefixes (MA-L); smart-home IoT, OUI = brand + OEM-module caveat

About this vendor.

Updated  ·  Confidence: High

BroadLink's IEEE registrant is "Hangzhou BroadLink Technology Co., Ltd," a Chinese smart-home company founded in 2013 and based in Binjiang District, Hangzhou, Zhejiang. It holds 9 MA-L blocks: eight registered to the Hangzhou entity (E8:70:72, 24:DF:A7, 34:8E:89, EC:0B:AE, 1C:D1:D7, E8:16:56, A0:43:B0, A8:DD:EC) and one — B4:43:0D — registered under the distinct legal name "Broadlink Pty Ltd" but at the same Hangzhou 310052 postcode, so it almost certainly belongs to the same group. These OUIs appear on BroadLink's Wi-Fi universal IR/RF remote hubs (the RM series), smart plugs and power strips (SP series), light switches, LED bulbs, environment sensors, and thermostats. The analyst caveat is the mirror image of a chipset-vendor lookup: BroadLink also ships its Wi-Fi modules, firmware, cloud, and app as a turn-key OEM package to other manufacturers, so a BroadLink OUI can surface on devices branded under entirely different names — and, conversely, some BroadLink-branded gear may present its chipset vendor's OUI. For triage, a BroadLink OUI indicates a BroadLink-platform device, but it does not by itself confirm the BroadLink consumer brand. The IEEE registry publishes no assignment dates, so none is stated here; any "date registered" on third-party MAC lookups is a database artifact, not an IEEE fact.

IEEE assignment
9 prefixes → "Hangzhou BroadLink Technology Co., Ltd" (E8:70:72, 24:DF:A7, 34:8E:89, EC:0B:AE, 1C:D1:D7, E8:16:56, A0:43:B0, A8:DD:EC) + B4:43:0D under "Broadlink Pty Ltd", all MA-L, Hangzhou, China [Confirmed] — IEEE MA-L (enrichment/registries/oui.csv lines 71, 1550, 7150, 8977, 15055, 24416, 27127, 33044, 39370)
Registry / block size
all MA-L (24-bit OUI); 9 blocks; no MA-M or MA-S assignments found [Confirmed] — IEEE oui.csv
Registrant name split
8 of 9 blocks read "Hangzhou BroadLink Technology Co., Ltd" (minor punctuation/casing variation across rows); B4:43:0D is registered as the separate legal name "Broadlink Pty Ltd" at the same 310052 postcode — treated as the same group, not independently confirmed as a subsidiary [Likely] — IEEE oui.csv line 27127
HQ / country
Room 101, 1/F, Unit C, Building 1, No. 57 Jiang'er Road, Changhe Street, Binjiang District, Hangzhou, Zhejiang 310052, China [Confirmed] — IEEE MA-L
Company status / founding
active; founded 2013; branded "BroadLink" [Confirmed] — ibroadlink.com, csa-iot.org member page
Device types
Wi-Fi IR/RF universal remote hubs (RM mini/RM4/RM pro/RM Max), smart plugs & power strips (SP/MP series), light switches, LED bulbs, environment/air-quality sensors, thermostats; also OEM Wi-Fi modules to third-party makers [Confirmed] — ibroadlink.com, home-assistant.io/integrations/broadlink, csa-iot.org
Notable products
RM-series universal IR/RF hubs; SP-series smart plugs
Registration date
IEEE publishes NO assignment/registration date (oui.csv columns are Registry, Assignment, Organization Name, Organization Address only); any "date registered" on third-party MAC tools is a database artifact, not an IEEE fact — so none is stated [Confirmed] — en.wikipedia.org/wiki/Organizationally_unique_identifier
Standards & ecosystems
Connectivity Standards Alliance (CSA/Matter) member; Amazon Alexa + Google Home integration; the RM Max hub was announced as Matter-certified in Jan 2026; proprietary FastCon BLE mesh [Confirmed] — csa-iot.org member page, homekitnews.com (2026-01-10)
OEM role
BroadLink supplies Wi-Fi modules, firmware, cloud, and app as a turn-key OEM package, so its OUI blocks may appear on devices branded under other names [Confirmed] — ibroadlink.com
Security context
2019 academic paper "Beware of the App!" (arXiv:1901.10062) found BroadLink companion apps used global broadcast discovery and sent device-state telemetry to servers in China; the open-source python-broadlink library shows the local UDP protocol requires an auth-key exchange but is otherwise proprietary; Home Assistant docs note cloud-"locked" devices stop accepting local connections [Likely] — arxiv.org/pdf/1901.10062, github.com/mjg59/python-broadlink, home-assistant.io/integrations/broadlink
CVE note
CVE-2023-50123 is attributed in aggregator summaries to a BroadLink alarm-bypass issue, but could not be independently confirmed from NVD during research — treat as unverified [Likely] — aggregator search summaries (not NVD-confirmed)
Investors
JD.com and Qihu 360 are reported as BroadLink investors; single-source, not independently corroborated [Likely] — ibroadlink.com
Related vendors
chipset suppliers (some BroadLink-branded Wi-Fi gear may surface under its module/chipset vendor's OUI); third-party OEM customers shipping BroadLink modules
Analyst note
A BroadLink OUI indicates a BroadLink-platform device, but because BroadLink ships OEM modules it does not by itself confirm the BroadLink consumer brand; conversely, absence of a BroadLink OUI doesn't rule out BroadLink, since some devices present their chipset vendor's OUI.
