Florawise — A8:0C:03 (MA-L)

OUI A8:0C:03 (hex A80C03) is an IEEE MA-L (24-bit, large) block — roughly 16 million addresses — assigned to Florawise, a Turkish smart-building IoT and cloud-software company headquartered at İTÜ Arı Teknokent in the Sarıyer district of Istanbul (No:6, postal 34467). Florawise builds networked commercial building-management hardware under its "Modular" product line: HVAC optimization controllers, environmental sensors, connectivity gateways, IR blasters, thermostats, thermostatic valves, and energy analyzers (e.g. Modular Max, Modular Sense, Modular Connect, Modular IR Blaster, Modular Thermostat Mini, Modular Thermostatic Valve, Modular Energy Analyzer X12, Modular Analyzer X4). These pair with the Flora AI cloud BMS platform, which integrates with the Tridium Niagara framework. Devices connect to that cloud over Wi-Fi/LAN, which is why a globally-administered MA-L block was registered. The vendor and device-type identity are well corroborated across the company website and business directories — founded around 2013, roughly 11–50 employees, with customers including CarrefourSA and TEKNOSA. As with all OUI prefixes, IEEE publishes no registration date for A8:0C:03; third-party lookup tools show a 2022-07-08 "date registered," but that is a database artifact from those tools, not an IEEE-published fact, and is treated here as unverified. No CVEs, threat-intelligence hits, or public security advisories specific to OUI A8:0C:03 or to Florawise devices were found in this research pass; the risk profile is that of standard commercial building IoT/BMS hardware. Generic concerns apply (network-exposed BMS, default credentials, unencrypted internal protocols), and because some controllers ride on the Niagara framework — an ecosystem that has historically carried CVEs across multiple vendors' implementations — operators should verify patching posture independently.

Security context

No Florawise-specific or A8:0C:03-specific CVEs / advisories / threat-intel found as of June 2026. Generic commercial IoT/BMS attack surface applies (network-exposed BMS, default credentials, unencrypted internal protocols); some controllers are Niagara-framework-based, an ecosystem with historical CVEs in other vendors' implementations — verify patching independently. Risk profile not elevated.

Analyst note

A globally-administered A8:0C:03 address identifies genuine Florawise building-automation hardware; expect it on commercial BMS/HVAC/IoT network segments rather than consumer devices — useful for asset classification.
