The exact $9 plug and the problem it solved are not identified in the available account, so there is no verified model or price to recommend. Here is how to choose a plug and configure the relevant Home Assistant features without treating outlet switching as a substitute for a proper shutdown.
What a smart plug can tell you about a laptop server
A smart plug sits between the outlet and the laptop’s power adapter. If its Home Assistant integration provides energy readings, it can report the electricity flowing to the connected device. Home Assistant documents Zigbee, Z-Wave, and Wi-Fi as smart-plug protocol categories; the specific device and integration determine what data and controls are available. Home Assistant explains individual device energy monitoring.

Energy data is useful for observing server consumption and spotting changes over time. It does not, by itself, explain why consumption changed, prove that the laptop is performing well, or control the laptop’s operating system. A plug that only exposes an on/off switch is not automatically an energy monitor.
Choose a plug that fits your Home Assistant setup
Check the specific model’s integration and exposed entities before buying. Protocol support alone does not establish that a plug will report energy in your installation.

- Protocol fit: Confirm whether the device uses Zigbee, Z-Wave, or Wi-Fi and that it works with the coordinator, hub, or network you already use.
- Energy readings: Verify that the Home Assistant integration exposes power or energy measurements, not just outlet switching.
- Network behavior: Check whether its control and reporting behavior suits your local network and reliability needs.
- Price and identity: Treat the $9 figure as unverified: there is no confirmed model, purchase date, or market attached to it.
Home Assistant does not rank brands or models in the cited documentation. A product should not be represented as the plug from the account unless its identity is confirmed.
Send energy readings to the Energy dashboard
An integrated energy monitor can be added as a source for Home Assistant’s Energy dashboard. The dashboard expects energy data; if an integration supplies instantaneous power instead, Home Assistant documents using the Riemann sum integral integration to derive energy from that power sensor. Review the sensor’s units and behavior before using it, since an unsuitable or incorrectly configured entity can produce misleading totals. See Home Assistant’s energy management documentation.

- COMPACT DESIGN: The plug fits perfectly into 1 socket, leaving remaining sockets and outlets free for use; ideal for multiple appliances like holiday lighting, heaters, fans, lamps, water kettles, coffee makers, and more
- CUSTOMIZE ROUTINES: Schedule your smart plug to turn on/off either at designated times, with a voice command, or even at sunrise and sunset
- NO 3RD PARTY APPS OR HUBS REQUIRED: Set up and manage connected devices directly in the Alexa app; no need for additional smart hubs or 3rd party apps
Wake the laptop with Wake on LAN
Wake on LAN sends a network “magic packet” to a device that supports Wake on LAN and is configured to accept it. The target’s MAC address is required. Home Assistant’s documented action uses broadcast port 9 by default; waking a device across subnets may require router support and may not be possible. Consult the Wake on LAN integration documentation and magic-packet action reference for the fields and network constraints.
Wake on LAN is not a general-purpose remote shutdown feature. A Home Assistant Wake on LAN switch can monitor state, but its turn-off behavior must be configured separately. Whether a particular laptop can be woken this way depends on its hardware, firmware, operating-system settings, and network arrangement.

Configure shutdown separately—and avoid routine hard power cuts
For a clean remote shutdown, use an operating-system-level method that is deliberately configured and secured. Home Assistant documents a command-line switch example for issuing a power-off command, but it is configuration-dependent rather than a universal laptop-server recipe. The example approach may involve remote shell access; permissions, credentials, and network exposure need to be considered before adopting it. Read the command-line integration documentation and adapt the setup to the target system rather than copying a command without understanding its effects.
Turning off a smart plug cuts power at the outlet; it does not ask the operating system to shut down cleanly. The cited Home Assistant documentation does not establish that cutting power to a running server is safe as a routine shutdown method, so use a configured shutdown action first.

Can switching the plug back on boot the laptop?
Only if the laptop’s firmware and power configuration support starting when AC power returns. The available documentation does not establish that behavior for any particular laptop. Check the machine’s firmware settings, then test on that hardware before relying on plug switching for recovery. A plug that restores power cannot guarantee the computer will boot.
