🔌 Best Local Control Wi-Fi Smart Plugs for Home Assistant
14 Wi-Fi plugs that talk to Home Assistant over your LAN, from Tasmota and ESPHome flash targets to local-API plugs with real-time energy monitoring.
✅ 14 Plugs Reviewed
✅ ESPHome & Tasmota
✅ Local API & Matter
✅ Energy Monitoring
Most cheap Wi-Fi smart plugs send every on/off command through a vendor cloud. When the internet drops, or the company changes its app, your automations stop. A local control plug instead accepts commands directly on your network, either through custom firmware such as Tasmota or ESPHome, through a documented local API (Shelly, TP-Link Kasa), or through Matter over Wi-Fi, which is local by design. Home Assistant can then switch it in milliseconds and log its power readings without any cloud account in the loop.
This guide also covers the energy-monitoring side: most picks below report watts, and several report voltage and current, which is perfect for detecting when a washer finishes or tracking a server rack. If you are still choosing a controller, start with our Home Assistant hardware guide, and for whole-home metering see our home energy monitors guide.
💡 Reality check before you buy: Reflashing is never guaranteed. Manufacturers quietly change chips and lock firmware, so a plug that was an easy Tasmota or ESPHome target last year may ship with a different module today, and OTA tools like tuya-convert no longer work on most new stock. Treat “flashable” as a bonus, not a promise, unless the plug ships pre-flashed. Vendor firmware updates can also change local protocols (TP-Link did this in the past), so keep Home Assistant updated and consider blocking plugs from the internet once they work. All picks here are US 120 V plugs; never open a plug while it is plugged in, and do not run space heaters or other continuous high loads on a plug near its 15 A limit.

🔍 How to Choose a Local Control Smart Plug
🏠
Pick a Local Path First
Decide how the plug will reach Home Assistant: custom firmware (Tasmota, ESPHome), a vendor local API (Shelly, Kasa), or Matter over Wi-Fi. All three avoid the cloud for daily switching.
🧰
Flashable vs Pre-Flashed
Flashing usually means opening the case and soldering to a serial header. If you want Tasmota without the work, buy a plug that ships with it, like the Martin Jerry pack.
📈
Energy Monitoring Depth
Watts are enough for “washer done” alerts. Voltage and current (SONOFF S31, S40) help diagnose loads. The HS300 meters each of its six outlets separately.
📐
Size and Placement
Mini plugs like the Kasa EP10 leave the second outlet free. Outdoor use needs a weather-rated plug such as the IP64 Kasa KP401.
📶
2.4 GHz Wi-Fi Health
Every plug here uses 2.4 GHz Wi-Fi. Twenty plugs on a weak consumer router is asking for drop-outs, so give them a dedicated IoT SSID and reserve their IP addresses.

🎯 Verdict: Buy it if you want to run your own ESPHome YAML on a mains plug.
🧩 PRE-FLASHED TASMOTA · ⭐ 3.4/54. Martin Jerry Tasmota Mini Smart Plug (4-Pack)
39 ratings · Sold as Tasmota, no hub required
Buy Here →
Martin Jerry is one of the few brands selling plugs branded as Tasmota on Amazon, so there is no soldering and no cloud app: you join the plug’s setup access point, enter your Wi-Fi, then point it at your MQTT broker or let Home Assistant’s Tasmota integration discover it. The listing does not mention energy monitoring, so treat these as simple on/off plugs. The rating is low and based on only 39 reviews, so check recent feedback first.
✅ Pros: Tasmota out of the box; 4-pack.
❌ Cons: 3.4 stars; no stated metering.
🎯 Verdict: The shortcut to cloud-free plugs if you already run MQTT.
🟦 BEST MATTER PLUG · ⭐ 4.3/55. Kasa KP125M Matter Smart Plug (4-Pack)
2,303 ratings · Matter LAN control with energy monitoring
Buy Here →
Matter is local by design: once commissioned, Home Assistant’s Matter server controls the plug directly over your LAN. The KP125M listing calls out Matter LAN control, compatibility with Apple Home, Alexa, Google Home and SmartThings, and energy tracking over time. Matter lets you share one plug with several ecosystems at once, which is handy in mixed households.
✅ Pros: Matter local control; energy data.
❌ Cons: Energy data via Matter depends on HA version.
🎯 Verdict: The best standards-based plug pack for multi-platform homes.
🔋 BEST POWER STRIP · ⭐ 4.6/56. Kasa HS300 Smart Power Strip
9,481 ratings · 6 outlets, 3 USB, surge protection
Buy Here →
The HS300 gives you six independently controlled outlets, three USB charging ports and ETL-certified surge protection, with energy monitoring for the connected devices. In Home Assistant each outlet appears as its own switch, which makes it ideal for a network rack, a 3D printer bench or an AV cabinet where you want to power-cycle one device and watch what each one draws.
✅ Pros: Six switched outlets; surge protection.
❌ Cons: USB ports are not individually switched.
🎯 Verdict: One device that replaces six plugs on a homelab bench.
💲 BEST BUDGET ON/OFF · ⭐ 4.5/57. Kasa EP10 Ultra Mini Smart Plug (4-Pack)
40,912 ratings · Compact 15 A plug
Buy Here →
If you just need lamps and fans on schedules, the EP10 is the cheapest way to get many plugs into the Kasa local ecosystem. The listing covers scheduling, countdown timers and Alexa or Google voice control over 2.4 GHz Wi-Fi. There is no energy monitoring, so pick the KP115 or KP125M for anything you want to meter.
✅ Pros: Tiny; massive review base.
❌ Cons: No power metering.
🎯 Verdict: The bulk-buy plug for simple lamp automations.

❓ Frequently Asked Questions
Can I flash any Wi-Fi smart plug with Tasmota or ESPHome?
No. Custom firmware needs an ESP8266 or ESP32 based module, and many current plugs use other chips (for example Beken or Realtek modules). Some of those can be converted with community tools such as OpenBeken or LibreTiny, but support varies by exact hardware revision. Check a device database and recent reports before buying a plug to flash.
Is Matter really local?
Yes. After commissioning, Matter devices are controlled over your local IP network. Home Assistant uses its Matter server add-on for this. Firmware updates and some extra features may still come through the vendor app. Compare more Matter plugs in our Matter smart plugs guide.
Should I block my smart plugs from the internet?
Many Home Assistant users put plugs on an isolated IoT VLAN with no internet access once they are set up. That stops surprise firmware updates. Matter, Shelly and Tasmota devices keep working fine; some vendor apps lose remote access, which is the point.
Wi-Fi or Zigbee plugs for Home Assistant?
Zigbee plugs are also local and strengthen your Zigbee mesh as routers, but need a coordinator dongle. Wi-Fi plugs need no extra hardware but load your router. See our Zigbee smart plugs guide to compare.
How accurate is smart plug energy monitoring?
Good enough for trends, standby loads and “appliance finished” detection, but not a calibrated meter. Plugs can be less accurate at very low loads of a few watts. For whole-home or billing-grade data use a dedicated meter from our energy monitor guide.
