A private application for
principals with more than one address

Every house you own, awake and accounted for.

Few people ever face it: residences on different continents, each with its own automation, alarm, and network stack: different apps, different logins, different people to call. You do not want another dashboard. You want a quiet glance that everything is all right, and the handful of numbers that matter. Patrimony Collection puts each house on a single card in your pocket, reading the systems already commissioned at the property, so the question never has to become a conversation.

How it works

Three steps, then it looks after itself.

01

Add the residence

Name it, place it, and it becomes a card: the villa, the flat in town, the lodge, the boat.

02

Connect the house

Link the automation already installed and Patrimony reads from it. Your estate manager or integrator can do this for you in one sitting: the path for the next house.

03

Keep an eye, lightly

Open the app and every house reports in a glance. If something needs you, it says so; if nothing does, it stays quiet.

The application

One card for each house you love.

Cards sit as a wallet holds them: the house, its weather, its status, and whoever looks after it. Tap through for detail; put it away when the answer is nothing to worry about.

What you see

The four things you would otherwise telephone about.

Connectivity The house is online Internet and network status per residence, with the last time each was reachable, so a dark camera feed has an explanation before you call anyone.
Security Armed, closed, quiet Alarm state, doors and gates, and who arrived or left. Notifications only for what you have asked to be told about.
Climate Conditions inside Temperature and humidity room by room, plus the places that matter most: the cellar, the gallery, the pool house, the plant room.
Environment Water, power, weather Leak and power alerts, generator and battery state, and the local forecast when a storm is heading for one of your coasts.
Integrations

It speaks to the systems already in the house.

We chose Home Assistant as the secure endpoint at each residence: a private interface that stays on the house, with no vendor cloud in the path between the systems you already trust and the card on your phone. Live state never leaves the property to be stored elsewhere; Patrimony only reads what that house chooses to present.

Home Assistant already speaks to the automation, alarm, network, and security systems most residences run. Where those systems are already commissioned, the integrator wires them into Home Assistant; Patrimony then reads what Home Assistant exposes. Existing equipment stays in place. Unusual setups are handled house by house through that same bridge.

Optional

PQ Shield

Optional post-quantum (PQ) encryption between your phone and that house (further security beyond standard SSL/TLS). Keys stay on the phone and the house. Requires iOS 26+.

House chat

Each house has its own private chat for the people you share it with. Messages and photos go directly between the house's own Home Assistant and your paired phones. There is no Patrimony chat server. Chat travels over standard SSL/TLS between your phone and the house.

The next house

Your people can add it. You do not need to be there.

Once the first residence is live, the same sitting repeats at every other house. Your estate manager or integrator follows a short path (secure tunnel, Home Assistant, a pairing code on your phone), and the new card appears beside the others. Live state stays on that property. You never have to brief a new app for each address.
