Before You Decide
Checks that matter before price.
- Confirm your supply type first: single-phase, split-phase, or three-phase.
- Decide whether DIN-rail wiring, CT clamps, or utility-meter access fits your switchboard.
- Choose between cloud convenience and local data access before comparing prices.
- For solar homes, make sure import, export, and load readings are measured at the right point.

Verdict
Choose by phase count first, then by whether built-in Wi-Fi convenience matters more than the simpler kWh-only metering path.
FAQ
Common decision questions.
Which energy meter should I choose?
Choose the option that matches your installation constraints and data path first. For 3 energy meter options, the full table is most useful after you know whether local data access, cloud convenience, backup behavior, solar visibility, or expansion matters most.
What should I check before comparing prices?
Check installation fit, required accessories, official documentation, monitoring platform support, and any unknown fields in the source-checked table. Price is only useful once those constraints are clear.
Can these devices work with local dashboards or Home Assistant?
HomeWizard kWh Meter 3-Phase, HomeWizard Wi-Fi kWh Meter 1-Phase, HomeWizard Wi-Fi kWh Meter 3-Phase list Home Assistant support in the catalog. HomeWizard kWh Meter 3-Phase, HomeWizard Wi-Fi kWh Meter 1-Phase, HomeWizard Wi-Fi kWh Meter 3-Phase are marked with local API support. Confirm firmware, region, and integration maturity before treating this as a final compatibility guarantee.
Are unknown fields a reason to avoid a device?
Not always. Unknown means the field was not confirmed from the reviewed source data. Treat it as a question for the installer, reseller, or manufacturer before making a purchase decision.
Does the verdict replace the specification table?
No. The verdict is a practical shortcut. Use the table to confirm the exact constraints that matter for your home, especially installation, monitoring, and support details.
