## 1. Product summary

**Name:** HA Cloud
**Domain:** https://ha-cloud.cz (marketing) · https://portal.ha-cloud.cz (SaaS portal)
**Category:** Software-as-a-Service (SaaS) — secure remote access platform
**Target use case:** Remote access to self-hosted [Home Assistant](https://www.home-assistant.io) instances over the public internet, without port forwarding, dynamic-DNS hacks, or third-party tunneling tools.
**Operator:** Czech provider; service hosted in the EU; GDPR-compliant.
**Operating language:** Czech (primary), English (secondary).

## 2. Problem solved

Home Assistant runs locally on a user's home network. To reach it from outside that network (mobile app while traveling, sharing access with family, remote troubleshooting by an installer), the user normally has to:

- open a router port and expose the HA instance directly (security risk),
- buy a static IP from their ISP (often not available on residential plans),
- run a self-hosted VPN such as WireGuard or Tailscale and maintain it,
- or subscribe to Nabu Casa (the official paid service from the Home Assistant team).

HA Cloud removes those requirements by:

1. Installing a small **Home Assistant add-on** inside the user's existing HA instance.
2. The add-on opens an **outbound WireGuard tunnel** to an HA Cloud edge node.
3. HA Cloud's reverse proxy terminates HTTPS (automatic Let's Encrypt certificate) and forwards traffic into the tunnel.
4. The user accesses their HA via a public URL — either a subdomain `*.ha-cloud.cz` (free) or their own custom domain (paid plans).

No router configuration, no public IP, no manual cert management.

## 3. How it works (technical architecture)

- **Client side:** Home Assistant add-on (Docker container) running on the user's HA host. Source is published as a public Home Assistant add-on repository.
- **Tunnel:** WireGuard (modern, fast, audited). Each device gets its own keypair; private key never leaves the device.
- **Edge:** Managed edge nodes running Traefik (reverse proxy) and the HA Cloud agent. Edge nodes are geographically distributed and load-balanced.
- **Control plane:** Flask-based SaaS portal (https://portal.ha-cloud.cz) where users manage devices, domains, plans, and billing.
- **Certificates:** Automatic via Let's Encrypt (DNS-01 challenge). Renewal is fully managed.
- **Database:** YugabyteDB (PostgreSQL-compatible distributed DB) for high availability.
- **Authentication on the user end:** The user still authenticates to Home Assistant itself; HA Cloud is purely the transport. Optional access policies (allowlist by source IP, basic auth, etc.) can be layered on at the edge.

## 4. Features

### Connectivity
- Outbound-only connection — no inbound ports opened on the user's router.
- WireGuard tunnel, end-to-end encrypted between HA add-on and HA Cloud edge.

## 6. Comparison with alternatives

| Alternative | Setup | Custom domain | Cost | Notes |
|-------------|-------|----------------|------|-------|
| **HA Cloud** | 5 min add-on install | Yes (paid plans) | from 19 CZK / €0.79 per month | EU-hosted, Czech provider, multi-device per account |
| **Nabu Casa** | 5 min built-in | No | $7.50 / month | Official; funds HA core dev; US-routed |
| **Port forward + Dynamic DNS** | Hours, requires router skill | Yes | Free | Security risk, exposes HA directly |
| **Cloudflare Tunnel** | ~30 min CLI setup | Yes | Free for personal | Powerful, but DIY config and policy maintenance |
| **Tailscale** | ~10 min app install | No (Magic DNS only) | Free for personal | Requires Tailscale client on every accessing device |
| **WireGuard self-hosted** | Hours, ongoing maintenance | DIY | Free | Highest control, highest effort |

## 7. Security & privacy

- All traffic between the HA add-on and HA Cloud edge is WireGuard-encrypted.
- Edge terminates HTTPS to local network — same trust model as port-forwarding to the user's own home, minus the open port.
- HA Cloud does **not** decrypt the user's Home Assistant data; HTTPS termination happens at the edge but is forwarded into the WireGuard tunnel.
- WireGuard private keys are generated on the user's device and never transmitted.
- GDPR: user data minimization, EU hosting, account export / deletion via portal.
- DKIM-signed transactional email via dedicated postfix sidecar (no third-party email forwarder).

## 8. Who is this for

- **Home users** who want safe remote access to their Home Assistant from a phone/laptop while away from home.
- **Smart-home installers** managing client deployments — central portal, per-client device list, separate billing.
- **Families and shared homes** — one account, multi-device, role separation.
- **Self-hosters** who don't want to maintain their own VPN.

## 9. Languages

- UI and emails are sent in the user's chosen website language.
- Czech and Slovak users receive Czech (`cs`/`cz`/`sk` → Czech template).
- All other languages receive English (default).

## 10. Frequently asked questions

**Q: Do I need to open a port on my router?**
