Homeassistant App: Syswatch

Docker container resource monitor for Home Assistant.

Real-time CPU, RAM, Network I/O, Disk I/O and PID counts for all Docker containers — including stopped HA add-ons — in a sortable, PWA-ready web interface with automatic refresh.

Features

Dashboard & Charts

• Sortable table: CPU %, RAM %, NET I/O, DISK I/O, PIDs per container — sort persists across reloads
• CPU sparkline: 30-measurement history per container in the table
• 24h history charts: click SYS CPU or SYS RAM card to open a canvas chart with the last 24 hours — stored in SQLite, survives restarts
• CPU temperature chart: click any temperature reading to open a 24h temperature history with threshold reference lines (60 / 75 / 90°C)
• HA Status card: Supervisor / Support / Health from Supervisor API — green / yellow / red

System Info

• SYS CPU / SYS RAM cards: color-coded progress bars (green ≤70 %, yellow ≤80 %, orange ≤90 %, red >90%) — clickable for 24h chart
• CPU temperature: from coretemp / k10temp hwmon — Package + per-core temps displayed below the CPU chart
• Footer versions: HA Core, Supervisor and OS version always visible

Container Management

• Container actions: Start, Stop, Restart, Kill (SIGKILL) — all with password confirmation
• Log viewer: last 200 lines with timestamps
• Port overview: all host-mapped ports, searchable and sortable — host ports are clickable links (http://<host-ip>:<port>)
• Stopped containers: shows stopped HA add-ons via Supervisor API

Telegram Notifications

• Unexpected container stop → 💥 alert with ▶ Starten inline button — start directly from Telegram
• Container restart detected → message updated to ✅, button removed
• CPU/RAM threshold alerts with Top 5 consumers (RAM: size + %)
• Configurable trigger and all-clear delays
• Startup notification with HA version, container count, host IP
• 📨 Test button in header (desktop) to verify bot setup
• Chat ID auto-detected on first /start message — no manual lookup needed
