## What reviewers say

**Generac PWRview Home Energy Monitor W2HEM** — Only one whitelisted tester, NYT Wirecutter, covers the Generac PWRview W2 (W2HEM), and only qualitatively: it was a former pick now dropped for poor availability and never lab-measured. Wirecutter says it uses machine learning like Sense and suits homes already in Generac's solar and battery ecosystem. No hands-on measurements exist. (1 sourced review.)
