Shenzhen Intellirocks Tech. Co. Ltd. — 2 prefixes (MA-L); Govee IEEE registrant, remaining blocks

A MAC address starting 5C:E7:53 or E0:2A:25 belongs to Shenzhen Intellirocks Tech. Co. Ltd., the IEEE-registered manufacturer behind the Govee consumer smart-home brand. These are two of the four MA-L blocks the company holds; the other two, D4:13:68 and D4:AD:FC, are already documented under the separate, already-published vendor-govee entry.

Shenzhen Intellirocks Tech. Co. Ltd. is registered at No. 3301, Block C, Section 1, Chuangzhi Yuncheng Building, Liuxian Avenue, Xili Community, Xili Street, Nanshan District, Shenzhen, Guangdong, China. It is a substantive, identifiable registrant rather than a bare single-OUI shell — 86 trademarks on file and multiple FCC equipment-authorization filings tie it to consumer electronics manufacturing.

No source ties a specific device model directly to 5C:E7:53 or E0:2A:25 individually. Bloomberg's company profile lists air-detection equipment and kitchen/small appliances under the parent company alongside Govee's better-known lighting and sensor lines, but that listing is not prefix-specific, so device assignment for these two blocks stays Likely rather than Confirmed.

The same chipset caveat documented for vendor-govee applies here: many Govee-branded Wi-Fi devices ship under their Wi-Fi/BLE chipset vendor's OUI (for example Espressif) rather than an Intellirocks-owned block, so the absence of 5C:E7:53 or E0:2A:25 does not rule out a Govee/Intellirocks device. IEEE's public OUI registry publishes no assignment or registration date for either prefix; a third-party "date registered" figure, such as maclookup.app's June 2025 date for 5C:E7:53, is a database artifact, not an IEEE fact.

IEEE assignment

2 of 4 prefixes (this entry) → Shenzhen Intellirocks Tech. Co. Ltd., registered Shenzhen, Guangdong, CN [Confirmed] — the IEEE MA-L registry (IEEE-sourced)

Registry / block size

MA-L (24-bit OUI); registrant holds 4 MA-L blocks total, 2 scoped to this entry (5C:E7:53, E0:2A:25); the other 2 (D4:13:68, D4:AD:FC) are the separate DONE vendor-govee entry [Confirmed] — the IEEE MA-L registry, /mac/vendor/govee/

HQ / country

No. 3301, Block C, Section 1, Chuangzhi Yuncheng Building, Liuxian Avenue, Xili Community, Xili Street, Nanshan District, Shenzhen, Guangdong 518000, CN [Confirmed] — the IEEE MA-L registry, https://hwaddress.com/company/shenzhen-intellirocks-tech-coltd/

Company status

active; substantive registrant (86 trademarks on file, multiple FCC equipment-authorization filings), not a bare single-OUI shell [Confirmed] — https://www.trademarkia.com/owners/shenzhen-intellirocks-tech-co-ltd, https://fcc.report/company/Shenzhen-Intellirocks-Tech-Co-L-T-D

Device types

Govee-brand smart-home electronics generally (smart LED lighting, smart plugs, recessed downlights, temperature/humidity sensors, meat thermometers); Bloomberg additionally lists air-detection and kitchen/small appliances under the parent company, but no source ties a device type specifically to 5C:E7:53 or E0:2A:25

[Likely] — https://www.bloomberg.com/profile/company/1875750D:CH, /mac/vendor/govee/

Notable products

Govee-branded smart-home device line (brand tie confirmed at the registrant level; not prefix-specific for this entry's two blocks) [Likely] — https://www.bloomberg.com/profile/company/1875750D:CH

Verified prefixes (this entry, both MA-L, same registrant)

5C:E7:53, E0:2A:25 [Confirmed] — the IEEE MA-L registry

Registration date

Unknown — IEEE's public OUI registry publishes no assignment/registration dates; maclookup.app's "07 June 2025" date for 5C:E7:53 is a third-party database artifact, not an IEEE fact [Confirmed] — https://maclookup.app/macaddress/5ce753

Special note

Same registrant as the DONE vendor-govee entry (D4:13:68, D4:AD:FC). Many Govee Wi-Fi devices ship under a chipset vendor's OUI (e.g. Espressif) rather than an Intellirocks-owned block, so absence of 5C:E7:53 or E0:2A:25 does not rule out a Govee/Intellirocks device [Likely, carried from vendor-govee's confirmed chipset caveat] — /mac/vendor/govee/

Related vendors

Govee (vendor-govee — same registrant, remaining 2 prefixes); Espressif (likely chipset supplier on some Govee Wi-Fi devices) [Confirmed relationship; Espressif tie is Likely] — /mac/vendor/govee/

Analyst note

A 5C:E7:53 or E0:2A:25 MAC identifies a Shenzhen Intellirocks Tech (Govee-family) device; triage alongside vendor-govee and chipset-vendor OUIs for full Govee/Intellirocks device coverage.
