Smart plugs are the easiest way to add intelligence to any device in your home. After testing over 20 different smart plugs with Home Assistant, I’ve found the best options for every use case and budget.

Why Smart Plugs Are Essential for Home Assistant

Smart plugs let you control “dumb” devices remotely, monitor energy usage, and create powerful automations. They’re perfect for lamps, fans, coffee makers, space heaters, and holiday decorations.

I have 12 of these throughout my house controlling lamps, fans, and holiday decorations. Check price on Amazon.

Best with Energy Monitoring: TP-Link Kasa Smart Plug HS110

For detailed energy monitoring, the TP-Link HS110 is unbeatable. It reports real-time power consumption, voltage, and current to Home Assistant.

Presence Detection: Turn off all smart plugs when everyone leaves home.
