Live Data Hub

Display live MQTT and REST API data directly inside your Obsidian notes.

Turn any note into a live dashboard: room temperatures from your smart home, server status from a REST endpoint, the current Bitcoin price — all updating in real time, right where you read them.

Features

  • MQTT over WebSockets (ws:// / wss://) — works on desktop and mobile.
  • MQTT over TCP (mqtt:// / mqtts://) — desktop only.
  • REST API polling with configurable interval, caching, retries.
  • Unified livedata code block with source: mqtt | rest discriminator.
  • Display variants: number, text, badge, toggle (more in roadmap).
  • Subscription pooling: one MQTT subscribe per topic, fan-out to all widgets.
  • Status indicator: live / stale / offline with configurable thresholds.
  • Relative timestamp with absolute hover tooltip.
  • Insert Wizard: command-palette modal to compose blocks visually.
  • Migration command: convert legacy mqtt / rest / api / live-data blocks to the new syntax.
  • Sidebar overview: all active data points at a glance.
  • Credentials in OS keychain (Electron safeStorage) on desktop, session-only on mobile.

Quick start

```livedata
source: mqtt
topic: home/livingroom/temperature
display: number
label: Living room
unit: °C
path: value
```

```livedata
source: rest
url: https://api.example.com/status.json
display: badge
label: API
path: data.status
interval: 30
```

Settings

  • Broker host, port, TLS, path
  • Auto-connect, default QoS
  • REST defaults (interval, caching, retries)
  • Credential storage (OS keychain on desktop, session-only on mobile)
  • Debug mode

Commands

  • Live Data Hub: Insert Widget — visual wizard
  • Live Data Hub: Migrate old blocks — convert legacy syntax
  • Live Data Hub: Open Overview — sidebar panel
  • Live Data Hub: Connect / Disconnect — manual MQTT control
  • Live Data Hub: Refresh All REST API Blocks
