OOnna
Onna is a Spanish manufacturer of KNX home and building automation hardware and software, developing 5"/7" touchscreen control panels, room controllers (ONNA T), servers (ONNA S), an iOS/Android app and ONNA Living, a cloud platform for residential building managers, plus integrations with Alexa, Sonos, Nuki, Airzone and Ajax. It operates under the legal entity Opendomo Things SL, incorporated in Galar (Navarra) in October 2018, with commercial headquarters at Paseo de la Castellana 200, Madrid, and roughly 11-50 employees. It is a bootstrapped/privately financed hardware manufacturer rather than a VC-backed startup; its identified backing is a €50,000 participatory loan from Sodena (the Navarre regional development company) plus Navarre Government/ERDF grants. David Alvira Iraizoz is board president, with Ander Gabilondo Areta, Joaquín Ros Felis (secretary), Alberto Salvo Arbiol and Fernando Sánchez Carrascal as board members.
