Aidon Oy — 44:96:2B (MA-L)

Aidon Oy holds a single IEEE MA-L block, 44:96:2B, registered to the company at Piippukatu 11, Jyväskylä, Finland — the only OUI assignment found for this organization across the IEEE MA-L registry, the IEEE MA-M registry, and the IEEE MA-S registry, with no MA-M or MA-S blocks under the same name. Despite the single-prefix footprint, Aidon Oy is a substantive, identifiable company rather than a shell registrant: founded in 2004 and headquartered in Jyväskylä, it is an active Finnish advanced-metering-infrastructure (AMI) vendor with offices across Finland, Sweden, Norway, and Denmark, roughly 5 million metering points deployed across the Nordics, and named utility contracts including Hafslund Nett and Smart Strøm Østafjells. Aidon was acquired by Gridspertise on November 9, 2023. Its Energy Service Devices — the 6000/7000/8000-series smart electricity meters — pair with a separable communication/system module supporting RF, NB-IoT, LTE-M, and remote-provisioned eSIM connectivity; a non-vendor Home Assistant/ESPHome community thread independently corroborates real-world deployment, describing a physical Aidon 6534 meter paired with a 6442SE communication module read over M-Bus. No Aidon-specific CVE or security incident surfaced in this research pass. A third-party tool (maclookup.app) lists a "registered 17 November 2015" date for this OUI, but IEEE's public registry publishes no assignment date, so that figure is treated as a database artifact and is not recorded as fact.
