-Since the Pi is headless, use an SSH tunnel:
+Replace `user@gateway-host` with your Pi username and hostname or IP address.
+
+On your computer, ask the Pi to print a fresh dashboard URL:
 
 ```bash
-# From your laptop/desktop
-ssh -L 18789:localhost:18789 user@gateway-host
-
-# Then open in browser
-open http://localhost:18789
+ssh user@gateway-host 'openclaw dashboard --no-open'
 ```
 
-Or use Tailscale for always-on access:
+The command prints `Dashboard URL:`. Depending on how `gateway.auth.token`
+is configured, the URL may be a plain `http://127.0.0.1:18789/` link or one
+that includes `#token=...`.
+
+In another terminal on your computer, create the SSH tunnel:
 
 ```bash
-# On the Pi
-curl -fsSL https://tailscale.com/install.sh | sh
-sudo tailscale up
-
-# Update config
-openclaw config set gateway.bind tailnet
-sudo systemctl restart openclaw
+ssh -N -L 18789:127.0.0.1:18789 user@gateway-host
 ```
 
+Then open the printed Dashboard URL in your local browser.
+
+If the UI asks for auth, paste the token from `gateway.auth.token`
+(or `OPENCLAW_GATEWAY_TOKEN`) into Control UI settings.
+
+For always-on remote access, see [Tailscale](/gateway/tailscale).
