What you need to wake your PC with Alexa

To wake your PC with Alexa you only need four things:

No extra hardware purchase, no paid plan, no hidden subscriptions. With SayBoot the Alexa skill and the Windows agent are both free for up to 2 PCs and distributed via the Amazon Alexa Skills Store and Microsoft Store respectively — so signed and verified by the platforms.

How Wake-on-LAN with Alexa works

The end-to-end flow is very simple but involves multiple steps behind the scenes:

Your voice -> Echo -> Amazon Alexa cloud -> SayBoot skill -> SayBoot server -> Windows agent (or Lambda with UDP magic packet) -> network card -> PC powers on.

Typical total time from the last word of the command to the LED lighting up: 1-3 seconds.

The technical core is Wake-on-LAN, a standard protocol that has existed for over 20 years: the network card of the powered-off PC stays in a low-power state and listens on the network segment for a specific packet (the "magic packet") containing its MAC address. When it receives it, it sends the power-on signal to the chipset. SayBoot adds the modern part: the voice front-end, OAuth onboarding without manual configuration, and a cloud relay to make it work from outside the home as well.

Step 1: Enable Wake-on-LAN in the BIOS and Windows 11

Wake-on-LAN must be enabled in two distinct places: BIOS and Windows. Skipping one means WoL won't fire.

BIOS

On the next PC reboot enter the BIOS (Del / F2 / F10 / F12 key depending on the manufacturer — you'll see it printed during boot). Look for one of these entries and set it to Enabled:

Save and exit (usually F10).

Windows 11 (and Windows 10)

Open Device Manager (Win+X -> Device Manager) -> Network adapters -> right-click your Ethernet card -> Properties -> Power Management tab. Enable both:

Then in the Advanced tab, find Wake on Magic Packet and set it to Enabled.

Watch out for Fast Startup: Windows 10 and 11 have "Fast Startup" enabled by default, which simulates a shutdown but is actually a partial hibernation and silently breaks Wake-on-LAN. Go to Control Panel -> Power Options -> Choose what the power buttons do -> Change settings that are currently unavailable, and disable Turn on fast startup. This is the #1 reason WoL "doesn't fire" even when everything else looks right.

Step 2: Install the SayBoot agent on your PC

Go to sayboot.com/app, click "Sign in with Amazon", and you'll land on the dashboard. Since you don't have any devices yet, the dashboard guides you through a three-step path. The first is "Install SayBoot on your PC" — click it, the Microsoft Store opens in the next tab, click Install.

The app is signed by Microsoft, zero SmartScreen warnings. After installation the agent starts automatically and opens the browser on the authorization page: one click on "Authorize", and the PC is paired. The browser tab automatically returns you to the dashboard after 1-2 seconds — the PC name is the Windows hostname (you can rename it any time at /app/devices, e.g. PC-Office or PC-Home).

No codes to copy, no manual MAC address setup. A typical user gets the PC registered in under a minute.

Step 3: Enable the SayBoot skill on Alexa

As soon as the agent is paired, the dashboard shows you an amber banner saying "Enable SayBoot on Alexa" with a large QR code on the left. Scan it with your phone: it opens the SayBoot skill page directly on your Amazon store. Tap "Enable to Use" -> tap "Link Account" -> confirm with "Allow". Done.

The dashboard banner automatically detects the linking (it reloads itself within 3 seconds) and disappears, replaced by the green "All set!" card with the example voice command.

Manual alternative if you prefer: on your phone open the Alexa app -> Skills & Games -> search for SayBoot -> Enable to Use -> Link Account -> "Allow". Same result, a couple more taps.

Using voice commands with Alexa

Say "Alexa, turn on \" (if you didn't rename it, it's the Windows hostname, like PC-Office or DESKTOP-AB12CD3). Echo replies "Ok", and within 1-3 seconds the PC powers on.

SayBoot stands out from traditional Wake-on-LAN skills because it also supports:

The action tied to "turn off" is configurable per device from the sayboot.com/app webapp (shutdown default for desktops, sleep recommended for laptops). You can create mixed groups where the desktop shuts down and the laptop sleeps, callable with a single command.

Using Alexa Routines for automatic wake-up

Once the PC is registered as a smart home device, Alexa treats it like any other light bulb or smart plug — so you can put it inside a Routine.

From the Alexa app: More -> Routines -> + -> pick a trigger (time, voice command, device). As the action add Smart Home -> PC-Office -> Turn On. So you can:

Routines are free and part of the Alexa client — no extra configuration needed from SayBoot.

Waking the PC remotely (away from home)

This is where SayBoot clearly differs from classic Wake-on-LAN solutions: it works away from home without opening ports on the router.

"Pure" Wake-on-LAN requires the magic packet to reach the local network segment of the PC. If you're traveling, you need a static public IP on the router + UDP 9 port-forwarding + possibly DynDNS. Fragile setup, often blocked by ISP routers (double NAT).

SayBoot avoids all of that with a cloud relay: the command leaves Alexa, reaches the SayBoot server, which forwards it to your Windows agent (if it's online on the home dispatcher PC) or directly generates the UDP magic packet on the LAN where the target PC sits. Deep dive on remote operation.

The only requirement is that at least one PC on your network is powered on (or in sleep with WoL enabled) to act as a dispatcher. If you only have one PC and it is off, the relay has nobody to forward to — this is one of the few physical limits of WoL.

Frequently asked questions

Does it work with Wi-Fi?

Wake-on-LAN strictly speaking requires a wired Ethernet connection on the target PC (the powered-off PC receives the magic packet through its standby network card). However SayBoot also supports the Wi-Fi scenario when there is a second PC powered on in the network acting as a dispatcher for wireless PCs.

Do I need a specific Echo?

No. Any Amazon Echo device works: Echo Dot, Echo, Echo Show, Echo Pop, Echo Flex. It just needs to be linked to the Amazon account where the SayBoot skill is enabled.

Does it work on Windows 10?

Yes. The SayBoot agent is certified for Windows 10 (version 1809 or higher) and Windows 11. The setup flow is identical.

Is it free?

Yes, forever. The core features (wake, shutdown, restart, sleep) are and will remain free for up to 2 PCs. A Premium version with advanced features will come later, but the basic use case stays free for everyone.

Can I wake the PC from outside my home?

Yes. SayBoot uses a cloud relay that forwards the command to your LAN without requiring port-forwarding on your router. The PC just needs Ethernet and to be plugged in.

Can I also shut down the PC with Alexa?

Yes, this is a differentiator versus traditional Alexa Wake-on-LAN skills: SayBoot natively supports shutdown, restart, sleep, and hibernate via the Windows agent, with no IFTTT or TriggerCMD required.

Quick troubleshooting

The PC doesn't power on after the voice command:

  1. Check on sayboot.com/app/devices that your PC shows as Online (green dot next to the name). If it's Offline, the agent isn't talking to the server — restart SayBoot from the Windows Start menu or check that the wmp.exe process is running (tray icon).
  2. Make sure Fast Startup is disabled (see Step 1 above).
  3. On the next shutdown, check that the network card LED stays on (or green) even with the PC powered off — if it's completely off, the card isn't powered and WoL can't work. Usually it's a BIOS EuP Ready / ErP Ready setting that needs to be disabled.

Alexa doesn't find the device on first try:

Discovery is normally automatic within a few seconds of account linking. If the device doesn't show up: from the Alexa app go to Devices -> + -> Add device -> Other -> Discover. If even after that the device is missing, check on sayboot.com/app/devices that pairing succeeded. If it's present in the webapp but not in Alexa, disable the skill from "Skills & Games -> SayBoot -> Disable Skill" and re-enable it — re-linking forces a clean discovery.

What makes SayBoot different

There are several solutions to wake your PC with Alexa — classic Wake-on-LAN skills, IFTTT integrations, Home Assistant setups. They all work within certain limits, but they share recurring shortcomings: manual MAC address setup, no shutdown support, no channel for use outside the local network without port-forwarding.

SayBoot covers the entire end-to-end flow in a single skill + agent:
