Which To Choose
Start with the practical fit, then read the table.
Emporia Vue 3 Home Energy Monitor
Best fit when single-phase, split-phase, and 3-phase panel monitoring kits, solar import/export visibility, and panel-installed CT clamp whole-home and circuit monitor.
Emporia Vue 3 3-Phase Energy Monitor
Best fit when single-phase, split-phase, or 3-phase 4-wire Wye systems with neutral; not for 3-phase 3-wire delta, solar import/export visibility, and electrical-panel energy monitor with three 200 A main CTs and optional branch-circuit sensors.
Aeotec Home Energy Meter
Best fit when region-specific 1-phase, 2-phase / split-phase, and 3-phase ZW095 variants., solar import/export visibility, and local dashboards and Home Assistant.
Leviton Whole Home Energy Monitor
Best fit when north American split-phase load center systems, solar import/export visibility, and load-center-mounted monitor with mains CTs.
Use this comparison when the priority is whole-home visibility rather than classic DIN-rail metering, and the shortlist includes clamp-based monitors for North American homes or light commercial panels.

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.

FAQ
Common decision questions.
Which energy meter should I choose?
Choose the option that matches your installation constraints and data path first. For 4 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?
Aeotec Home Energy Meter list Home Assistant support in the catalog. Aeotec Home Energy Meter 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.
