If you're looking for an Alexa skill to wake (and possibly shut down) your PC by voice, the 2026 landscape splits into three categories of solutions with different characteristics. Here we don't rank specific products feature-by-feature (individual tool details change over time), but we focus on when to choose one category over another and what realistic limits to expect.
Category 1 — Classic Wake-on-LAN skills
Alexa skills dedicated exclusively to powering on the PC via Wake-on-LAN magic packets. They've existed for several years, are widely available, and well documented in English-language guides.
How they work:
You manually configure the MAC address of your PC's network card on a developer web portal, enable the Alexa skill from your account, pair the PC inside the skill. You say "Alexa, turn on \
When it makes sense:
- You have a single PC, wired via Ethernet
- You only need wake and don't need shutdown/restart by voice
- You're fine copying the MAC address by hand from your PC to the developer portal
- You're willing to give up use from outside the home (or you're one of the rare users with a static public IP + a router with UDP broadcast port-forwarding enabled)
Realistic limitations:
- No voice shutdown (shutting down still requires a software channel inside the PC, which WoL doesn't provide)
- Manual MAC setup, to redo if you change PC or network card
- Fragile remote use: depends on the ISP, the router, and a port-forwarding chain often blocked behind CG-NAT
Cost: typically free. Implementations differ in web portal UX details and the number of PCs supported.
Category 2 — DIY integrations with IFTTT / TriggerCMD / Home Assistant
Composable solutions: combine Alexa + an intermediary service + an agent on the PC to cover all use cases (wake + shutdown + automations).
How they work:
Alexa hears a generic voice command, turns it into a webhook trigger to a service (IFTTT, Home Assistant, a home mini-server). The service contacts an agent on your PC (TriggerCMD, a Python script, an HA automation) that executes the requested action.
When it makes sense:
- You already have your own smart-home infrastructure (Raspberry Pi with Home Assistant, home Linux server, IFTTT Pro/Pro+ subscription)
- You enjoy fine-tuning behavior (complex automations, conditions, time-based logic)
- You're comfortable with webhooks, YAML, certificates, and network configuration
Realistic limitations:
- High technical bar: without prior experience, setup takes days of tutorials, trials, and config errors
- IFTTT is paid for more than 2 applets (Pro or Pro+ plan since 2020)
- More failure points: Alexa, IFTTT, agent, network. When something breaks, debugging isn't trivial
- The agent must always be running on the PC and reachable from the cloud service
Cost: from free (self-hosted Home Assistant) to tens of dollars/year (IFTTT Pro + hardware).
Category 3 — All-in-one skills with integrated Windows agent
Alexa skills that include in their own ecosystem a dedicated Windows client, covering both wake (magic packet) and shutdown (native Windows command from the client). SayBoot fits this category — it's built exactly on this model.
How they work:
You download a Windows agent from the Microsoft Store, do OAuth pairing with "Sign in with Amazon" (no MAC to copy), enable the Alexa skill. Pairing is automatic, the agent registers the PC in the provider's cloud, and Alexa sees the PC as a native smart-home device. You can say "turn on", "turn off", "restart", "suspend" — all commands handled by the same skill.
When it makes sense:
- You want to wake AND shut down by voice without intermediary tools
- You're looking for a simple setup that works in 5 minutes without specialized technical knowledge
- You need operation from outside the home without touching the router
- You want a signed agent from the Microsoft Store, no Windows security warnings
- You're fine with centralized management via webapp instead of dozens of config files
Realistic limitations:
- Requires installing an agent on the PC (it's not "Alexa-only")
- Free plans typically have a limit on the number of PCs (for SayBoot: 2 PCs free, forever)
- It doesn't offer the unlimited customization of Home Assistant-style setups
Cost: often free in the base plan, paid premium plans for advanced features (in SayBoot's case: the core use case — wake, shutdown, restart, sleep — stays free forever).
Decision in three questions
- Do you only need wake? -> Category 1 (classic WoL skill). Free, setup in 15-30 minutes if you can copy the MAC.
- Do you need full control (on + off + automations), have technical patience and a server already at home? -> Category 2 (DIY with Home Assistant or IFTTT).
- Do you want on + off in a single skill, with no complex setup, working away from home? -> Category 3 (all-in-one skill with Windows agent — SayBoot, a free Wake-on-LAN Alexa skill).
Most home / office users searching for "wake pc with alexa" fall into case 3: they want it to work fast, even from away, including shutdown, without learning a framework.
Frequently asked questions
Is there a free Alexa skill to turn on a PC?
Yes. Classic Wake-on-LAN skills are usually free, and all-in-one skills often have a free plan too: SayBoot is free for up to 2 PCs, including shutdown, restart and sleep.
Can Alexa also turn off my PC?
Not with Wake-on-LAN alone, which can only power a PC on. Shutting down needs a program on the PC that receives the command: an all-in-one skill with a Windows agent, or a DIY setup with IFTTT, TriggerCMD or Home Assistant.
Do I need port forwarding to wake my PC from outside the home?
With classic Wake-on-LAN skills, usually yes: a static public IP and port forwarding, which often fail behind CG-NAT. Skills that use a cloud relay and an agent on the home network need no router configuration.
Do I need Home Assistant or IFTTT?
No. They are worth it only if you already run a smart-home server or want custom automations. IFTTT is paid beyond 2 applets, and every extra service is one more point of failure.
Does waking the PC with Alexa work over Wi-Fi?
Turning on needs a wired Ethernet connection on the target PC, because the Wi-Fi card has no power when the PC is off. Shutdown, restart and sleep work over Wi-Fi too, since the agent receives the command over the internet.
Which solution should I choose?
To wake a single wired PC at home, a classic Wake-on-LAN skill is enough. For custom automations with a server you already own, go DIY. For on and off in one skill, working away from home without technical setup, choose an all-in-one skill with a Windows agent.
Things to keep in mind
- The market changes. Specific features of "classic" WoL skills and Windows agents evolve. If you're evaluating today, look at the individual product page on the Alexa store for the up-to-date feature list.
- Hands-on testing (install + try + uninstall if it doesn't work) is often more informative than reading comparisons. Free skills have no switching cost.
- Reliability depends more on the provider's cloud infrastructure than declared features. A product with fewer features and a stable cloud beats a feature-rich one with frequent outages.
