The XDA piece on smart plugs as troubleshooting tools made a quiet point most owners miss: the plug is only as useful as the app it depends on. A router gets stuck, a Pi-hole hangs, a printer needs a hard restart — a smart plug fixes all of it from the couch, but only if the controlling app actually answers when you tap. We tested eight smart plug control apps for Android across budget Tuya plugs, TP-Link gear, Samsung’s SmartThings stack, and the self-hosted Home Assistant path that ducks the cloud entirely.
The list is built around the hardware most readers actually own and the workflows that hold up at 2 a.m. when a device needs to come back from a stuck state. Pricing, platform notes, and one real weakness per app are called out.
What to look for in a smart plug control app
Five things matter when the app has to be reliable rather than novel:
- Local control. Cloud-only apps fail when your internet is the thing you are trying to reboot
- Routine and schedule depth. Sunset / sunrise triggers, time-based rules, conditional logic
- Voice integration. Google Assistant, Alexa, or both — for hands-free triggers
- Energy monitoring. Watt-level visibility for plugs that report power draw
- Cross-platform shared access. Family members need to control the same plugs from their own accounts

The 8 best smart plug control apps for Android
1. Smart Life — best for budget Tuya plugs
Smart Life by Tuya is the app behind a huge share of budget-brand smart plugs sold on Amazon and AliExpress. If a plug ships with “Tuya” anywhere in the manual or pairs via the Tuya cloud, Smart Life controls it. The app covers scheduling, scenes (multi-device automations), energy reporting on plugs that support it, and Alexa / Google Assistant integration.
Where it falls short: Cloud-dependent by default; no native local control. Setup wizard occasionally fails to find devices and you have to retry. UI density can feel busy.
Pricing:
- Free: All core features
- Paid: None on the consumer app
Platforms: Android, iOS
Bottom line: Pick Smart Life when your plugs are budget-brand Tuya devices and you can live with cloud dependency.
2. TP-Link Tapo — best for TP-Link Tapo gear
TP-Link Tapo is the controller for the Tapo line (P100, P105, P110 power-monitoring plugs). The app is cleaner than Smart Life’s, the setup wizard is reliable, and the Tapo P110 model’s energy monitoring is the most accurate budget option for measuring real device draw.
Where it falls short: Locked to Tapo hardware (Kasa plugs use a separate app). Some older Tapo plugs lack energy reporting.
Pricing:
- Free: All features
- Paid: None on consumer app
Platforms: Android, iOS
Bottom line: Pick TP-Link Tapo when Tapo plugs are your hardware and accurate energy monitoring matters.
3. Kasa Smart — best for TP-Link Kasa gear
Kasa Smart is the Tapo app’s older sibling for TP-Link’s earlier Kasa-branded plug line. The HS103 and KP105 plugs run through Kasa Smart with reliable on-LAN control even when the cloud is unreachable, which makes it the most resilient option for “reset the router via smart plug” scenarios.
Where it falls short: TP-Link has been migrating new hardware to Tapo, so the Kasa app sees fewer product additions. Some routine logic is shallower than Tapo’s.
Pricing:
- Free: All features
- Paid: None
Platforms: Android, iOS
Bottom line: Pick Kasa Smart when older Kasa-branded TP-Link plugs are what you own and on-LAN reliability matters.
4. Google Home — best for routine-driven control
Google Home is the cleanest cross-brand controller if you live in the Google Assistant ecosystem. The routine editor (sunrise, sunset, time, presence triggers) is the best-in-class for plug automation, and the Matter / Works-with-Google compatibility list is broad enough that most modern plugs work out of the box.
Where it falls short: Single-brand apps (Tapo, Kasa) sometimes expose more device-specific options. Initial pairing for some off-brand plugs requires the manufacturer app first, then Google Home for routines.
Pricing:
- Free: All features
- Paid: None
Platforms: Android, iOS, Web
Bottom line: Pick Google Home when routine automation across multiple plug brands is the priority.
5. Amazon Alexa — best for voice-first control
Amazon Alexa is the strongest pick for households built around Echo devices. The Routines editor is comparable to Google Home’s, the voice-first model is the most polished, and the Skills ecosystem brings in plug brands that other multi-brand controllers miss.
Where it falls short: Without an Echo in the home, the value proposition narrows. Some plug brands require enabling a Skill before they appear in routines.
Pricing:
- Free: All features
- Paid: None
Platforms: Android, iOS, Echo devices
Bottom line: Pick Amazon Alexa when Echo devices are in the home and voice control is the primary trigger.
6. SmartThings — best for multi-brand control
SmartThings by Samsung is the most ambitious multi-brand hub. The 2024 Matter integration brought direct support for a long list of smart plugs, the routines layer reads from sensors (motion, temperature, presence) for conditional automation, and the SmartThings hub adds Zigbee / Z-Wave plugs to the supported list.
Where it falls short: UI has been redesigned several times and discovery can feel inconsistent. Some advanced routines require the Routines (Beta) section.
Pricing:
- Free: All features
- Paid: None
Platforms: Android, iOS
Bottom line: Pick SmartThings when multi-protocol plug support (Matter, Zigbee, Z-Wave) and sensor-driven routines are the priorities.
7. Home Assistant Companion — best for self-hosted control
Home Assistant Companion is the Android client for the open-source Home Assistant smart-home platform. Combined with a Home Assistant server (Raspberry Pi, NUC, NAS), it gives every plug local control that ignores the cloud entirely, plus the most powerful automation engine on this list. Custom scripts, conditional rules, and dashboards all run from your own hardware.
Where it falls short: Requires a Home Assistant server before the app does anything useful. Initial setup has a learning curve. Some plug brands need community integrations rather than first-party.
Pricing:
- Free: App and server are both open-source
- Paid: Optional Home Assistant Cloud subscription ($6.50/mo) for remote access without port forwarding
Platforms: Android, iOS
Bottom line: Pick Home Assistant Companion when local control, custom automation, and cloud-free operation matter most.
8. WiZ Connected — best for Signify WiZ gear
WiZ Connected is the controller for Signify’s WiZ-branded plugs and bulbs. The line is one of the cheaper Matter-compatible options, and the app handles scenes, schedules, and room-based grouping without the Tuya cloud’s complications.
Where it falls short: Locked to WiZ hardware. Setup needs a working 2.4 GHz Wi-Fi network on the same SSID as your phone during pairing.
Pricing:
- Free: All features
- Paid: None
Platforms: Android, iOS
Bottom line: Pick WiZ Connected when Signify’s budget Matter plugs are the hardware in the home.
How to pick the right one
If your plugs are budget Tuya devices from Amazon or AliExpress, install Smart Life. It is the only app most of those plugs ever pair with.
If you bought TP-Link gear, use TP-Link Tapo for newer Tapo plugs or Kasa Smart for older Kasa models — the apps are not interchangeable.
If you want routines that cross brands and live in the Google ecosystem, Google Home is the best multi-brand controller. If your home is Echo-first, Amazon Alexa runs the same job from the Alexa side.
If sensor-driven automation and Matter / Zigbee / Z-Wave compatibility matter, SmartThings is the most ambitious hub app. If you want local control with no cloud dependency, Home Assistant Companion plus a Pi-based server is the strongest path.
If you bought Signify’s budget Matter plugs, WiZ Connected is the only app you need.
FAQ
What is the best free smart plug control app?
Every app on this list is free to install and use. Home Assistant Companion is the only one that ships with no monetization model at all because the entire platform is open-source.
Can I control multiple plug brands from one app?
Yes, via Google Home, Amazon Alexa, SmartThings, or Home Assistant. These apps integrate across brands once each plug has been paired through the manufacturer app first. Matter-compatible plugs can often skip the manufacturer app entirely.
Do smart plug apps work without internet?
Most cloud-first apps (Smart Life, Tapo, Google Home, Alexa) lose remote control when your internet drops, though many keep on-LAN control through your local Wi-Fi. Home Assistant Companion paired with a local server is the only fully cloud-free option on this list.
What is the most reliable smart plug app for rebooting a router?
Kasa Smart with a Kasa plug is the most resilient pairing because it keeps on-LAN control even when the cloud is unreachable. Home Assistant with a locally-flashed Tasmota or ESPHome plug is the most cloud-independent option overall.
Does Google Home work with all smart plugs?
Google Home supports any plug certified as Works with Google Home or compatible with Matter. The list is broad but not universal. Check the plug’s box for the Works with Google Home logo, or pair it via the manufacturer app and look for it in Google Home’s device list afterward.
