Read full description

Merlin is the AI that lives in your building. Not in the cloud: a unit installed in your home, office or hotel that understands everything you already have (KNX, Loxone, ABB free@home, climate, lights, energy, cameras, access control) and controls it for you. This app is your way in. TALK TO YOUR BUILDING • Ask the way you would ask a person: "turn off the living room lights", "how much energy have I used today?", "warn me if the warehouse goes above 28 degrees". • The Merlin Avatar listens and answers by voice, hands-free: for when your hands are busy, for a reception desk, or for anyone who would rather not touch the screen. Accessible mode included. • Create automations and alerts by talking: "every day at 7 raise the blinds", "if the door opens at night, call me". EVERYTHING ON ONE SCREEN • The whole installation at a glance: consumption, outdoor weather, alarms, presence. • Climate, lighting, plugs, ventilation and media per room. • Energy and cost in real time, by hour, week and month. • Security: arm, disarm, check sensors and cameras. • Notifications when something needs your attention. • Sign in with Face ID or fingerprint. YOUR DATA STAYS HOME The app connects directly to your Merlin unit on the local network and, elsewhere, through an encrypted remote access. Your installation and its history live in your unit, not on a third-party server; what the AI needs is anonymised first. WHO IT IS FOR Homes, offices, hotels, agencies and industry with a Merlin unit installed. The app requires an active unit and the user credentials provided by the installer.
