Your whole home, in one beautiful app. O-DOMO brings your lights, shutters, heating, scenes, alarm and cameras together in one elegant app — whatever technology they speak. Wired KNX and wireless Zigbee, Matter and Wi-Fi devices live side by side, and it is so simple you can set it up yourself: no programming, no ETS, no technician required. SO EASY, ANYONE CAN DO IT • Plug it in — the O-DOMO server is a simple program you run on a spare tablet or a small mini PC. Connect it to your home network and it finds your gateways automatically. • Add your devices — a guided wizard learns each one as you use it: flip a switch, walk past a sensor. Wireless devices are recognised as you pair them. No technical skills needed. • Enjoy your smart home — control everything from the app, at home or anywhere. Prefer a hand? A certified installer can set it up for you. WORKS WITH WHAT YOU ALREADY OWN • KNX — the wired standard for lights, shutters, dimmers, thermostats and sensors. • Zigbee — add wireless sensors, plugs, bulbs and buttons with a simple USB coordinator. • Matter — bring compatible devices on your own network into the same home. • Wi-Fi — Shelly, Tasmota and Sonoff devices join directly. • NUKI smart locks, plus gates and portals. EVERYTHING YOUR HOME CAN DO • Lights & shutters — dim lights, set scenes and move every shutter or blind with a tap, or automatically. • Scenes & automation — Good night, Leaving home, sunrise and sunset: your house responds on its own. • Heating & climate — thermostats, temperature and humidity readings, with history charts. • Alarm module — turn your existing sensors into a full intrusion alarm with exit/entry delays, siren support, 24-hour smoke and water-leak zones and instant push alerts. Optional add-on. • Camera module — see every camera live, at home or away, in the same app; cameras with person detection can trip the alarm. Optional add-on. • Remote control module — replace the remotes for your TV, streaming box, projector, screen or air conditioning. Optional add-on. • Wall tablet mode — turn a spare tablet into an always-on control panel for the whole family. PRIVATE BY DESIGN Your home data lives on your own server, inside your home — not in the cloud. Remote access works without opening any ports on your router; the cloud only relays encrypted commands and notifications and stores no home data. FOR THE WHOLE FAMILY Owner, admin and guest roles with PIN-protected administration. O-DOMO speaks your language: English, Spanish, French, Catalan, Dutch, German and Italian. Note: O-DOMO is the free companion app for the O-DOMO home server. It requires the O-DOMO home server running on a device (a tablet or mini PC) connected to your home network and your installation.
