PC Boot — Wireless Power-On
Power on your computer wirelessly via an optional PCIe module. Supports BIOS-level wake, Home Assistant integration, and cross-platform compatibility (Windows / macOS). Even when your PC is fully powered off, UltraBARX remains in control of your desk.
Key Features
PC Boot adds a powerful new capability to your UltraBARX.
BIOS-Level Wake
Supports full S5 wake from complete shutdown. The PCIe module simulates a physical power button press.
Home Assistant Integration
Create automations in Home Assistant — detect presence with SenseCube, turn on lights, and power on your PC, all in one flow.
Cross-Platform Compatible
Works with Windows and macOS. No additional drivers required.
Works Even When PC Is Off
UltraBARX remains fully functional — control lights, music, and scenes even while your PC is powered down.
Installation Guide
Two steps: hardware installation + software configuration.
Install the PCIe Module
Insert the wireless power-on module into your computer's PCIe slot.
- Purchase the optional PC Boot Wireless Module (PCIe interface)
- Power off your computer and disconnect the power cable
- Open the case and insert the PCIe module into an available PCIe slot
- If your module includes a power LED cable, connect it to the motherboard's PWR_LED header (optional)
- Close the case and reconnect power
Configure in Ultra Workspace
After hardware installation, complete the pairing process via software.
- Make sure CoreBAR is powered on and connected to the same network
- Open Ultra Workspace on your computer
- Navigate to Settings → PC Boot
- Click Search for Modules — Ultra Workspace will scan for available PCIe modules
- When your module appears, click Pair and follow the on-screen instructions
- Once paired, a "Power On" button will appear on CoreBAR
Test Power-On
Verify that everything is working as expected.
- Shut down your computer (full shutdown, not sleep)
- On CoreBAR, locate the "Power On" button (can be added to any Profile)
- Tap the button — your computer should start up normally
- If the computer doesn't start, check the pairing status and Wi-Fi connectivity
Use Scenes
Where PC Boot makes the biggest difference.
Remote Wake
Start your computer from the living room, kitchen, or anywhere else — no need to get up.
Smart Automation
With Home Assistant: SenseCube detects presence → lights turn on → PC powers on automatically.
One-Touch Workspace
Add "Power On" to your UltraBARX Profile. One button starts your entire workspace.
Troubleshooting
Common issues and how to fix them.
Possible causes: PCIe slot not properly seated, insufficient power, or computer not powered on. Solution: Check the PCIe connection and confirm the computer is plugged in and powered on.
Possible causes: CoreBAR too far from the computer, or network latency. Solution: Ensure CoreBAR and the computer are on the same local network with good signal strength.
Possible causes: PC Boot entity not properly configured in HA. Solution: Check the PC Boot entity in the Home Assistant integrations page and verify your automations reference it correctly.
Possible causes: CoreBAR and computer on different networks. Solution: Connect both CoreBAR and your computer to the same Wi-Fi or LAN, then retry pairing.
