+name: HA Blue SSH access
+description: How to SSH into Home Assistant Blue — port 2222, user csader, not root
+type: reference
+---
+
+SSH to HA Blue: `ssh -p 2222 csader@192.168.86.36`
+
+- Port 2222 (SSH add-on)
+- User `csader` — root is blocked by AllowUsers
+- Key: `~/.ssh/id_ed25519` (ed25519, csader@chrissader.com)
+- Use `sudo` for privileged operations (e.g., HACS install)
+
+**How to apply:** When needing to run commands on HA Blue directly (install HACS, check custom_components, etc.), use this SSH path.
