Alarms that do not fail
Heartbeats, offline detection, delivery confirmation, and idempotent arm/disarm. The one thing that must work, works.
Home safety, on your terms
Argus turns the Home Assistant you already run into a reliable, AI-verified alarm — multi-home, private by design, and a fraction of the cost of a traditional alarm service.
Built for the moment that matters
When the alarm is armed and something happens, the right person gets a fast, accurate alert — every time.
AI-verified PhotoCheck
Motion events are verified against a camera frame so you get real alerts, not false alarms at 3am.
Your Home Assistant stays private
The add-on talks outbound only over an encrypted WebSocket. Nothing about your home is exposed to the internet.
Every home, one app
Cabin, apartment, parents’ house — add as many homes as you like and switch between them in a tap.
A fraction of the cost
Professional-grade safety layered on hardware you already own, at a fraction of the monthly cost.
Safety, end to end
Intrusion today; fire, water, freeze, glass-break, and door-lock control on the roadmap. Not general automation — just safety.
How to connect your home
About ten minutes, start to armed. No ports to open, nothing exposed to the internet.

Armed dashboard
Your Home Assistant only ever connects out to Argus over an encrypted WebSocket — Argus never reaches in. The install token is the single per-home secret, and you can rotate or revoke it from the app at any time.
