HomeWizard Energy Socket

Quick verdict

A smart plug that earns its place by doing energy monitoring really well. Plug in an appliance, and you get accurate real-time power data flowing into Home Assistant through a local API. Setup runs through the HomeWizard app, where you switch on Local API, and no cloud sits in the path after that. Perfect for tracking how much your dryer, fridge, or EV charger actually costs. The HomeWizard Energy integration is one of the best-rated in Home Assistant, and this socket is a big reason why. EU socket only, but for European users it is hard to beat.

Standout: Wi-Fi smart plug with accurate built-in energy monitoring and a fully local API.

Compatibility snapshot

Why it stands out

• built-in energy monitoring with accurate per-device consumption tracking
• excellent local API integrates smoothly with Home Assistant's energy dashboard
• runs entirely on your local network once Local API is switched on, and the cloud connection can be turned off for good

Reasons to hesitate

• EU socket type only, not available for US or UK outlets
• Wi-Fi-based, so it depends on wireless network stability
• no Zigbee or Thread, does not contribute to a mesh network

Best for

• EU-based Home Assistant users who want per-device energy monitoring
• users tracking individual appliance consumption for Home Assistant's energy dashboard

Avoid if

• you are outside the EU and need a different socket type
• you prefer Zigbee or Thread devices for mesh network benefits

Privacy and local-control notes

Local Wi-Fi device with a local API you switch on in the HomeWizard Energy app. After that Home Assistant polls the socket locally and the energy data stays on your network. You can switch the cloud connection off entirely, but the app and firmware updates stop working when you do.

Buying reality check

Price notes: Mid-range for a smart plug, but the energy monitoring capability adds significant value over basic on/off plugs.
