Best Smart Plugs for Home Assistant in 2026: Zigbee, Z-Wave, and Wi-Fi Options Compared
Smart plugs are the easiest entry point into home automation. No wiring required, no electrician needed — plug them into any outlet, connect them to Home Assistant, and you can control any device plugged into them with automations, schedules, and voice commands.
But not all smart plugs work equally well with Home Assistant. Some require cloud connections that break your local automations. Some use proprietary protocols that lock you into one ecosystem. And some simply don’t report energy usage — one of the most useful features a smart plug can have.
This guide covers the best smart plugs for Home Assistant in 2026 across every protocol — Zigbee, Z-Wave, and Wi-Fi — so you can pick the right one for your setup.
What to Look For in a Smart Home Plug
Before we get to recommendations, here’s what actually matters when choosing a smart plug for Home Assistant:
Local control. The plug should work without a cloud connection. If the manufacturer’s servers go down, your automations should still work. Zigbee and Z-Wave plugs are always local. Wi-Fi plugs vary — some require cloud, some support local control.
Energy monitoring. The best smart plugs report real-time power consumption — watts, amps, voltage. This lets you build automations based on device state (your washing machine automation fires when power drops to near zero, meaning the cycle is done) and track your electricity usage.
Home Assistant compatibility. Not all smart plugs integrate cleanly with Home Assistant. We only recommend plugs with native integrations or proven community support.
Build quality. A smart plug lives in your wall outlet potentially forever. Cheap plugs run hot, have unreliable radios, and fail within a year. The plugs below are all proven reliable over extended use.
Best Zigbee Smart Plugs
Zigbee smart plugs are our first recommendation for most Home Assistant users. They’re local by default, affordable, and extend your Zigbee mesh network — every mains-powered Zigbee device makes your whole network stronger.
You’ll need a Zigbee USB dongle to use these — see our guide on Zigbee vs Z-Wave for Home Assistant for recommendations. The SONOFF Zigbee 3.0 USB Dongle Plus is a great place to start.
1. SONOFF S31 Zigbee — Best Overall
Price: ~$15–18 each
The SONOFF S31 Zigbee is the smart plug we reach for first. It has everything you need — reliable Zigbee connectivity, energy monitoring, compact design that doesn’t block the second outlet, and rock-solid Home Assistant support through ZHA or Zigbee2MQTT.
The energy monitoring is genuinely useful. Once you have a few of these around your home you start to see exactly where your electricity goes — the gaming PC on standby drawing 40 watts, the old TV that never fully powers off, the coffee maker that uses more power than you’d think.
Setup in Home Assistant takes under two minutes: put the plug in pairing mode, open ZHA in Home Assistant, click Add Device, and it pairs automatically. From that point it shows up as a switch with power, voltage, and current sensors.
Best for: General use, energy monitoring, extending your Zigbee mesh
2. Aqara Smart Plug — Best for Apple HomeKit Users
Price: ~$25–30 each
The Aqara smart plug is a premium Zigbee option that works natively with both Home Assistant and Apple HomeKit. If you have an iPhone and want your smart plugs to work in the Apple Home app as well as Home Assistant, the Aqara is the cleanest solution.
Build quality is noticeably better than budget options — it feels solid, runs cool, and has a satisfying physical button. Energy monitoring is included. The Aqara integration in Home Assistant is well maintained and reliable.
The higher price per plug makes it less ideal for large deployments but it’s worth it if HomeKit compatibility matters to you.
Best for: Apple ecosystem users, premium build quality, dual Home Assistant + HomeKit setups
Best Z-Wave Smart Plugs
Z-Wave plugs operate on the interference-free 900MHz frequency band — ideal for apartments or homes with congested 2.4GHz environments. They cost more than Zigbee equivalents but offer guaranteed cross-brand compatibility and exceptional reliability.
3. Zooz Z-Wave Plus Plug ZEN15 — Best Z-Wave Option
Price: ~$35–40 each
The Zooz ZEN15 is the Z-Wave smart plug with the strongest reputation in the Home Assistant community. It handles high-wattage devices — up to 15 amps — making it suitable for appliances like washing machines, dishwashers, and space heaters that would damage lower-rated plugs.
Energy monitoring is comprehensive — power, energy, voltage, and current are all reported to Home Assistant. The ZEN15 is particularly popular for laundry automation: Home Assistant watches the power draw and sends a notification when the washing machine finishes its cycle.
Zooz is a US-based company with excellent customer support and active participation in the Home Assistant community — a meaningful differentiator in a space full of anonymous manufacturers.
Best for: High-wattage appliances, laundry automation, Z-Wave setups, reliability-focused users
Best Wi-Fi Smart Plugs
Wi-Fi smart plugs connect directly to your router without a hub or dongle. The tradeoff is that most require cloud connections — but there are exceptions worth knowing about.
4. Kasa Smart Plug EP25 — Best Wi-Fi Option
Price: ~$15–20 each (often cheaper in multipacks)
The Kasa EP25 is the Wi-Fi smart plug with the best Home Assistant integration. Unlike most Wi-Fi smart home devices, Kasa plugs support local control — Home Assistant communicates with them directly over your local network without going through TP-Link’s cloud servers.
Energy monitoring is included and works reliably in Home Assistant. The Kasa integration is officially supported and actively maintained. Setup is straightforward — add your Kasa credentials to Home Assistant and all your Kasa devices appear automatically.
The main advantage over Zigbee: no dongle required. If you’re not ready to commit to a Zigbee setup yet, Kasa plugs let you start building automations immediately with hardware you already have — a Wi-Fi router.
Best for: Beginners not yet running Zigbee, multipack value, no-hub setups

Smart Plug Automations Worth Setting Up
Once your smart plugs are in Home Assistant, here are the automations that make them genuinely useful:
Laundry done notification: Monitor the power draw on your washing machine with a Zooz ZEN15 or SONOFF S31. When power drops below 5 watts after being above 400 watts, send a notification to your phone. Never forget wet laundry in the machine again.
Standby power elimination: Schedule your TV, gaming console, and entertainment system to cut power completely between midnight and 6am. Most entertainment devices draw 5–20 watts on standby indefinitely — eliminating this can save $50–100/year in electricity.
Coffee maker schedule: Turn on your coffee maker at 6:45am Monday through Friday so coffee is ready when you wake up. Turn it off automatically after 2 hours so you don’t come home to a burnt pot.
Away mode: When everyone leaves the house — detected via phone GPS — automatically turn off all smart plugs. No more worrying about whether you left something on.
Sunrise/sunset lighting: Turn floor lamps on at sunset and off at a set bedtime automatically every day without touching a schedule.
Our Recommendation
For most Home Assistant users starting out: buy a 4-pack of SONOFF S31 Zigbee plugs.
At around $15–18 each they’re the best value in the category. Energy monitoring, reliable Zigbee connectivity, clean Home Assistant integration, and compact design that doesn’t hog the second outlet. Four plugs covers your most-used devices and meaningfully extends your Zigbee mesh network at the same time.
If you’re not running Zigbee yet and want to start immediately: grab a Kasa EP25 multipack while you sort out your Zigbee dongle. They work locally, integrate cleanly with Home Assistant, and you can always repurpose them once you go full Zigbee.
