Sia NAS Manager

About

Sia NAS Manager is an independent Android app for keeping an eye on — and safely operating — several NAS units and Linux home servers from a single console. It is deliberately not a file manager: instead of browsing shares or moving files, it focuses on status, monitoring, diagnostics, and safe day-to-day operations such as service control, reboot, shutdown, Wake-on-LAN, and an SSH terminal. Built with Kotlin, Jetpack Compose, Material 3, Room, DataStore, and WorkManager, it works without a Sia Makerlab account and without any relay or middleman server.

Serverless, direct connection. The app talks directly from your device to the servers you configure — over SSH for Generic Linux, over the DSM Web API for Synology, and over the REST API for TrueNAS SCALE. There is no Sia Makerlab server in the path, so your server addresses, accounts, keys, and logs are never collected by us. Credentials are encrypted at rest with the Android Keystore (AES-GCM), and Room stores only a credential reference — never plaintext secrets.

Provider-neutral by design. Rather than hard-coding vendor screens, the app is organized around capabilities a server reports — system info, storage pools, SMART, services, terminal, reboot, and more — so each menu appears only when the connected device actually supports it. The first release targets Generic Linux (SSH), Synology DSM, and TrueNAS SCALE, plus a Demo mode that simulates healthy, low-space, degraded-RAID, overheating-disk, and offline scenarios without a real NAS. The provider-core architecture is built so additional systems (QNAP, Unraid, OpenMediaVault, and others) can be added later without changing the shared app code.

Safe operations. Self-signed certificates and SSH host keys are pinned on first use (TOFU); if a fingerprint later changes, the app blocks the connection and asks you to re-confirm rather than trusting it silently. Destructive actions such as reboot and shutdown are guarded with confirmation and optional biometric authentication, and sensitive values — IP addresses, hostnames, tokens, API keys, SSH fingerprints, and paths — are masked in any logs.

Features

• Unified dashboard for multiple NAS and Linux servers — online state, CPU, memory, and storage usage at a glance
• Health summary per server (healthy / caution / warning / critical / unknown) with icons and text, not color alone
• Storage pools, volumes, disks, SMART status, temperature, and network interfaces where the provider supports them
• Service status with start, stop, and restart where your permissions and the provider allow
• Log viewer (journalctl / dmesg, DSM Log Center, TrueNAS logs) with sensitive data masked
• Built-in SSH terminal for Generic Linux (and for DSM / TrueNAS when SSH is enabled) with helper keys and paste confirmation
• Power management: Wake-on-LAN, reboot, and shutdown, guarded by confirmation and optional biometric authentication
• Background light checks via WorkManager with local notifications for offline, low-space, and pool/disk problems
• Demo mode with healthy, low-space, degraded-RAID, overheating-disk, and offline scenarios — no real NAS required
• Serverless and account-free: direct device-to-server connection, credentials encrypted with the Android Keystore (AES-GCM)
• Self-signed certificate and SSH host-key fingerprint pinning (TOFU) that blocks silent identity changes
• Adaptive UI for phones, tablets, and foldables, in English and Korean
