Your home, calmly
connected.
Your home shouldn't need an app store to turn on a light. ÆtherCasa runs on top of Home Assistant — the open-source project you already trust — and gives it the polish it deserves on every device you own.
Your home. Private. Unified.
Your data stays on your network. We don't see device states. Our cloud is a thin relay — if it disappeared tomorrow, your house still works.
Simple, not simplified.
Powerful enough for the people who run Home Assistant on a NUC. Intuitive enough for the people who live with them.
Built on open standards.
Home Assistant, Matter, Z-Wave, Zigbee, Hue, HomeKit. Your locks and lights are yours — we're just the surface they come together on.
Your home runs
the automation.
We just carry the message.
A thin bridge runs on your Home Assistant. It opens an outbound tunnel to our cloud. Clients connect to the cloud. Nothing inbound to your home. Ever.

Carries the message.
Same interface.
The security posture,
plain and short.
We read the security page so you don't have to. But you can — it's on /security, and it's not in lawyer voice.
No passwords to leak.
We cannot read your payloads.
Bridge and clients, inspectable.
Ever. Not as a pledge — as a policy.
"We don't store your device states. Your home runs the automation, our cloud just carries the message. If we disappear tomorrow, your house still works. That's the point."
