Eve Energy (Matter)

The privacy pick. Eve Energy talks over Thread rather than Wi-Fi and needs no cloud account, so control stays local instead of depending on a company's servers, which is exactly what went wrong for Wemo owners. It is also made in US, UK, European and Australian versions, handy if a move crosses a border. It costs more than the Kasa plugs and needs a Thread border router, such as a HomePod or a fourth-generation Echo. Detailed power readings are in the Eve app, and it is at its best in an Apple Home setup.
