Best smart plugs with local control and energy monitoring
Local smart plugs with energy monitoring for Home Assistant: real local control over Wi-Fi, Z-Wave, or Thread, accurate power data, and no cloud account.
On this page
Smart plugs are where a lot of smart homes stop being theoretical and start being useful.
They’re cheap enough to deploy everywhere, practical enough to automate daily annoyances, and good enough to show whether your smart home stack handles local control and energy monitoring well.
The picks worth your time:
- Best overall for Home Assistant: Shelly Plug US Gen4
- Best for Apple Home with a cleaner local story: Eve Energy
- Best for Z-Wave / HA households: Zooz ZEN04 800LR Smart Plug
Quick verdict
If your home revolves around Home Assistant, the easiest smart plug recommendation here is still a Shelly, and the current US model is the Shelly Plug US Gen4.
If your house is much more Apple Home-centric and you want a smarter local-first compromise than the usual cloud Wi-Fi plug junk, Eve Energy is the better fit.
If you already have Z-Wave and want something that behaves like local infrastructure instead of a consumer gadget, Zooz ZEN04 is a very strong answer.
How we judge smart plugs
The right smart plug isn’t the one with the prettiest app. It’s the one that does these things well:
- Reliable local control
- Useful energy telemetry
- Strong Home Assistant reality
- Reasonable offline behavior
- Low drama at scale if you buy several
Best overall for most Home Assistant users: Shelly Plug US
Shelly wins because it’s one of the cleanest combinations of local control, energy monitoring, and Home Assistant friendliness.
Why it stands out:
- excellent HA fit
- useful plug-level energy monitoring
- low cloud dependence
- works well for practical automations instead of just novelty toggles
Buy the Shelly Plug US Gen4 if you are buying new. It handles 15 A / 1800 W, meters voltage, current, power and energy, and ships Matter-certified over Wi-Fi and Bluetooth, with Zigbee firmware available by pressing the device button five times. The older Plus Plug US in the product notes below is still a fine plug if you already own one, but it is Wi-Fi and MQTT only with no native Matter.
The main caution is that it’s a better product for Home Assistant people than for buyers who just want the slickest mainstream voice-assistant experience.
Best for Apple Home households: Eve Energy
Eve Energy makes the most sense when you want something that feels more native in the Apple world without falling straight into cloud-heavy plug territory.
Why it makes sense:
- excellent Apple Home fit
- stronger privacy and local-first posture than many ordinary Wi-Fi plugs
- Matter / Thread direction makes more sense than legacy app-dependent junk
The catch is that Matter and Thread are still not the cleanest path for every household. If your network and border-router story are messy, the experience can become less magical than the product pitch suggests.
Best for Z-Wave + Home Assistant households: Zooz ZEN04 800LR Smart Plug
Zooz is the least glamorous pick here, which is part of why I like it.
If you already use Z-Wave and Home Assistant, this kind of plug behaves more like infrastructure and less like a vendor account funnel.
Why it works:
- excellent HA support
- clean local behavior
- strong fit for buyers who care about dependable control more than app polish
The downside is obvious: it isn’t trying to be a universal mainstream ecosystem plug. If your goal is specifically watching a desktop’s draw, the best smart plugs for PC power monitoring covers plugs with the resolution to track idle-versus-load wattage.
What to avoid
Avoid buying smart plugs based only on marketplace ratings and “works with” badges.
That is how people end up with:
- cloud-dependent junk that flakes out during outages
- weak or inconsistent energy reporting
- products that technically connect to Home Assistant but feel annoying to live with
Compatibility notes
Home Assistant
The strongest Home Assistant choices here are the Shelly Plug US Gen4 and Zooz ZEN04. Eve Energy is viable, but it’s more ecosystem-sensitive.
Apple Home
Eve Energy is the cleanest Apple Home fit. The other two make more sense if Apple Home isn’t your center of gravity.
Google Home / Alexa
These plugs are less exciting as pure voice-assistant recommendations. This page is intentionally biased toward local-first quality, not just easy badge coverage.
Final recommendation
For most readers building around Home Assistant, buy the Shelly Plug US Gen4 first.
If you’re more Apple Home-first and still want a decent local-first story, buy Eve Energy.
If your stack already revolves around Z-Wave, buy Zooz ZEN04.
