SwitchBot (Woan Technology) — holds MA-L OUI B0:E9:FE; consumer smart-home, OUI = brand + chipset caveat

[ 01 ] — Context

About this vendor.

Updated  ·  Confidence: Medium

SwitchBot's IEEE registrant is "Woan Technology (Shenzhen) Co., Ltd." — the legal entity behind the SwitchBot brand — which holds the IEEE MA-L OUI B0:E9:FE (IEEE-verified). The entity is registered in Shenzhen, Guangdong, China (a Bao'an District industrial park per directories), while the global brand HQ is in Hong Kong with a U.S. entity (SwitchBot Inc., Delaware) and Tokyo operations. This OUI maps to SwitchBot consumer smart-home devices: hubs, smart switches and bots (button pushers), curtain and blind robots, smart locks, contact and motion sensors, plugs, cameras, and vacuums. The "SwitchBot" trademark is held by Woan Technology (filed 2017-03-07), with the corporate parent often cited as WonderLabs, Inc. The key analyst point is the chipset caveat — many SwitchBot devices are BLE-only or use third-party Wi-Fi/BLE chipsets, so some devices still surface under the chipset vendor's OUI (Espressif, Telink, Beken — all covered) rather than Woan's. For triage, a Woan Technology OUI (B0:E9:FE) maps to SwitchBot smart-home devices, but also expect SwitchBot gear under Espressif/Telink/Beken OUIs — confirm by device behavior, not OUI alone.

Verified prefix
B0:E9:FE (MA-L) [Confirmed] — IEEE MA-L registry
Special note
SwitchBot/Woan holds its own IEEE OUI (MA-L B0:E9:FE). But many SwitchBot devices are BLE-only or use third-party Wi-Fi/BLE chipsets, so some devices surface under the chipset vendor's OUI (Espressif/Telink/Beken) rather than Woan's. The IEEE registry publishes no assignment dates, so none is stated here. [Confirmed]
Related vendors
Espressif, Telink, Beken (Wi-Fi/BLE chipset vendors SwitchBot devices may surface under); WonderLabs (parent)
Analyst note
A Woan Technology OUI (B0:E9:FE) maps to SwitchBot smart-home devices. However, because SwitchBot uses third-party radios in some products, also expect SwitchBot gear to appear under Espressif/Telink/Beken OUIs — confirm by device behavior, not OUI alone.
