EventGhost: Ultimate Guide to Automating Your Windows PCEventGhost is a free, open-source automation tool for Windows that listens for events (like key presses, device input, network messages, scheduled timers, or application state changes) and reacts by running actions or scripts. It’s especially popular with home theater PC (HTPC) builders, hobbyists automating peripherals, and power users who want to reduce repetitive tasks. This guide covers everything from installation and core concepts to advanced setups, real-world examples, troubleshooting, and best practices.
What EventGhost does (quick facts)
- Event-driven automation for Windows: reacts to inputs and state changes by performing actions.
- Plugin-based: extendable with plugins for remotes, IR hardware, network protocols, and applications.
- Supports Python scripting: build complex logic with Python.
- Free and open source: community-driven, no licensing fees.
Getting started
Requirements
- Windows 7 or later (Windows ⁄11 recommended).
- .NET Framework (EventGhost includes required components).
- Optional: IR receivers, USB devices, network access, or other hardware depending on desired integrations.
Installation
- Download the latest EventGhost installer from the project page or a trusted mirror.
- Run the installer and follow the prompts. Choose the default options unless you have specific needs.
- Launch EventGhost. The main window is split into a tree (left) showing configured events and macros, and a log pane (right) showing incoming events and executed actions.
Core concepts
Events
Events are named triggers that EventGhost listens for. Examples:
- Keypresses from a remote control (e.g., Remote.Button.OK)
- Windows messages (e.g., a program opening)
- Network events (e.g., a webhook)
- Timer events (scheduled)
Events are hierarchical and can carry payload data (event.value).
Actions
Actions are the responses EventGhost can execute when an event occurs. Built-in actions include:
- Sending keypresses
- Running programs or batch files
- Controlling volume
- Sending HTTP requests
- Executing Python code
Macros
A macro is an event-to-action mapping. You create a macro by dragging an action into the tree and binding it to an event. Macros can contain sequences of actions and conditional logic.
Plugins
Plugins add event sources or actions. Popular plugins:
- LIRC / HID / MCE for remote controls
- Network plugins for TCP/UDP, HTTP server, or webhooks
- Window and process plugins to detect application states
- Media center plugins (e.g., Kodi, MediaPortal)
Basic example: Map a remote button to launch VLC
- Install and configure your IR receiver plugin (e.g., LIRC or HID).
- Press a button on your remote while watching the EventGhost log — an event name will appear.
- Create a new macro: right-click the event in the log and choose “Create Macro from Event.”
- In the action list, add “Execute” → “Start Application” and set the path to vlc.exe.
- Save. Press the button to test — VLC should open.
Intermediate: Conditional logic and variables
EventGhost supports Python scripting for logic that goes beyond simple actions.
Example: Only launch a media app if the screen is off (pseudo-workflow)
- Use a plugin or script to detect display state (some systems expose power status or you can query screensaver/processes).
- Create a Python action that checks the display state and returns True/False.
- In the macro, add a Conditional Action that runs the app only if the Python check passes.
Small Python snippet for a condition action (in EventGhost’s Python action block):
import ctypes def is_screen_on(): # Simple check via GetSystemMetrics for screensaver/monitor state is platform-limited; # for many systems, you can inspect monitor power via SendMessage or platform APIs. return True # Replace with real check as appropriate eg.result = is_screen_on()
Note: Replace placeholder with a platform-appropriate API call or plugin-based check.
Advanced topics
1. Using EventGhost as a network-triggered automation server
- Enable the HTTP Server or TCP/UDP plugin.
- Create macros that respond to HTTP requests or UDP packets.
- Secure your network: restrict binding interfaces, use local network only, and add token-based checks in Python actions.
Example use cases:
- Trigger dimming lights from a smartphone via a simple webhook.
- Start a movie and set the AV receiver to the right input when a streaming app starts.
2. Complex scripts and reusable libraries
- Organize recurring logic into Python modules inside EventGhost.
- Use the “Python Script” action to import and reuse functions.
- Example modules: device control wrappers, state machines, logging helpers.
3. Integrating with smart home systems
- Talk to Philips Hue, Home Assistant, MQTT, or other APIs using HTTP or MQTT plugins.
- Use EventGhost as a bridge: receive remote events or IR commands and publish MQTT messages, or vice versa.
4. Timers and scheduled tasks
- Use the Timer plugin to create repeatable schedules.
- Store state in persistent variables (EventGhost supports saving configurations and variables) to track last-run times or modes.
Example projects
-
HTPC “movie mode” macro:
- Event: Remote.Button.Play
- Actions: Dim lights via HTTP API → Set TV input via HDMI-CEC plugin → Launch Kodi → Set system volume → Start movie playlist
-
Presence-triggered automation:
- Event: Packet from phone on local network or MQTT presence message
- Actions: Unlock smart lock via API → Turn on hallway lights → Start welcome playlist
-
Automated backups:
- Event: Scheduled midnight timer
- Actions: Stop a service → Run backup script → Start service → Send completion email via SMTP plugin
Tips, best practices, and organization
- Name events and macros clearly and hierarchically (e.g., Remote.LivingRoom.Power).
- Keep macros small and reusable; use subfolders for related functionality.
- Use Python for complex logic, but prefer built-in actions for simple tasks (easier to debug).
- Add logging actions to critical macros to capture status and errors.
- Backup your EventGhost configuration regularly (it’s an XML file).
- Test macros step-by-step before chaining many actions together.
Troubleshooting
- Event not appearing: ensure plugin for the device is installed and properly configured; check device drivers.
- Action failing to run: try executing the action manually (e.g., run the program path directly) to verify permissions and paths.
- Delays or missed events: check for conflicting system processes, USB power settings, or thread saturation — consider adding small delays between actions.
- Python errors: inspect the log pane for stack traces; test code snippets in isolation.
Alternatives and complementary tools
- AutoHotkey — excellent for keyboard/mouse automation and GUI scripting.
- PowerShell scheduled tasks and scripts — powerful for system administration automation.
- Home Assistant or Node-RED — better for large, distributed smart home setups; use EventGhost as a local bridge when needed.
Tool | Strengths | When to choose |
---|---|---|
EventGhost | Event-driven, plugin-rich, local device control, Python extensibility | HTPC, local device/IR automation, lightweight server tasks |
AutoHotkey | Fine-grained GUI automation, hotkeys | Desktop automation focused on keyboard/mouse |
Home Assistant | Large smart-home ecosystem, integrations | Centralized smart home control across many cloud/local platforms |
Node-RED | Visual flow-based automation, IoT-focused | Networked device integration, MQTT-heavy setups |
Security considerations
- Beware exposing EventGhost’s network interfaces to the internet without authentication.
- Sanitize inputs used in Python actions if events originate from untrusted sources.
- Limit system commands and file access from automated scripts; run with least privilege necessary.
Resources and learning
- Official EventGhost documentation and plugin lists.
- Community forums and GitHub repositories for plugins and example configs.
- Python snippets and recipes for common automation tasks.
If you want, I can:
- Walk through configuring a specific plugin (e.g., LIRC or HTTP Server).
- Draft the exact EventGhost macro and Python code for a specific scenario (HTPC movie mode, smart-lighting scenes, MQTT bridge).
