• Proxmox / Ceph dashboards in ioBroker with HTML/CSS
• UniFi Network dashboards (clients, APs, switches, traffic, VLANs)
• Heating & energy (Viessmann + Oilfox) with live and history views
• Backup & device watcher dashboards for hosts, backups, status & errors
• Script monitor dashboard for heartbeat states and script health
• Shown on wallboards / TVs via MinuVis and custom Default-1 themed layouts

A dedicated script monitor / heartbeat setup keeps track of all major ioBroker scripts:

• Each script reports a heartbeat state (alive, timestamp, last error).
• A central monitor aggregates the states and
  • marks unhealthy or stalled scripts,
  • raises warnings if heartbeats are missing,
  • can trigger Discord/Telegram notifications for script failures.
• Common conventions:
  • Heartbeat states under 0_userdata.0.*.Scripts.*
  • Unified naming for easier dashboard integration.
• Dashboards show at a glance:
  • Which scripts are running,
  • Last execution time,
  • Error counters and status badges.
