Tech4home, Lda — 3 prefixes (MA-L)

A MAC address beginning with 80:F1:F1, 30:D9:7F, or 9C:7D:C0 belongs to Tech4home, Lda, a Portuguese manufacturer of remote controls (RCUs) for IPTV, cable, and pay-TV set-top boxes. Tech4home holds three MA-L blocks.

Tech4home (brand "t4h") is based in São João da Madeira, Aveiro, Portugal, and has operated for 20+ years as a B2B custom-hardware supplier to pay-TV operators. Its product lines — NOTUS, CASTER, MODU, YUBA, NOYO, SENIOR, KIDS, and Alva Programmable Buttons — are wireless remotes and accessories, not general-purpose network gear.

Trade press corroborates devices that actually carry these MAC prefixes: Bluetooth Low Energy (BLE) voice remote controls built for RDK- and Metrological-enabled set-top boxes, alongside broader remote-control hardware using BLE, RF4CE, Wi-Fi, and IR. This makes the vendor a legitimate, identifiable company rather than a bare single-OUI shell.

No IEEE assignment date exists for any block — IEEE's public OUI data (the IEEE MA-L registry) publishes only Registry, Assignment, and Organization fields, never a date, so no registration date is reported here.

Analyst note

all three prefixes (80:F1:F1, 30:D9:7F, 9C:7D:C0) are directly, dedicatedly registered to Tech4home, Lda — not sub-allocations of an IEEE shared base — so all three reliably identify Tech4home hardware.
