Overview

HomeWizard kWh Meter 3-Phase is a practical fit for households that want to monitor a three-phase solar circuit, EV charger, heat pump, or whole mains feed without moving into a heavier installer-only monitoring ecosystem.

Why it stands out

  • HomeWizard positions it as a Wi-Fi DIN-rail kWh meter for both consumption and production monitoring.
  • The official product page states it supports live bidirectional import and export measurement.
  • HomeWizard also documents a local API and an official Home Assistant integration, which gives it more long-term flexibility than many app-only consumer monitors.
  • The official phase guidance says the 3-phase model supports up to 100 A continuous load per phase and can also be used in 3P3W installations without a neutral wire when applicable.

Best fit

This meter makes the most sense when:

  • the home or monitored circuit is three-phase,
  • you want a clearer homeowner app experience than many DIN-rail Modbus meters provide,
  • solar production or EV/heat-pump tracking matters,
  • and local integrations may matter later.

What to know before buying

  • It is stronger for households and light-commercial style monitoring than for open industrial control workflows.
  • The local API is available, but some longer-history and per-phase app features are tied to HomeWizard's Energy+ layer.
  • Installation is still breaker-box work and HomeWizard explicitly warns that it should only be installed by someone familiar with electrical installations and the risks involved.
