The IoT Portal gives you reliable access to your Home Assistant installation — even in setups where classic port forwarding is not an option (for example behind carrier‑grade NAT / CGNAT on mobile networks).
In practice, Home Assistant stays in your local network. For remote access we use an outbound connection and expose it cleanly through the portal.
How it works
On site (vehicle / boat / remote location) you typically have a 4G/5G router. Home Assistant is connected via LAN. On the device, ZeroTier runs as a client and establishes an outbound connection to our endpoint — no inbound ports required.
Encryption & security
We want remote access to be both convenient and properly secured:
- HTTPS (TLS/SSL): Access to the portal is served via HTTPS, encrypting traffic between your browser and the portal.
- ZeroTier tunnel: The connection between your on‑site installation and our endpoint runs inside the encrypted ZeroTier tunnel (outbound, no open inbound ports).
That means traffic is encrypted end‑to‑end along the path (browser ↔ portal via HTTPS and portal ↔ installation via the ZeroTier tunnel).
What you get
You’ll get a dedicated portal URL (for example wunschname.mobile-iot.net) and login‑based access to your Home Assistant UI. Depending on your package we can also add health checks, status reports, and alerting.
Onboarding
We set this up with you once: connect router and Home Assistant, join the ZeroTier network, and then we provision portal access and your URL. After that it’s just “log in and go” — from anywhere.
