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?
IAMMETER WEM3080, IAMMETER WEM2067, IAMMETER WEM3050T, IAMMETER WEM3080T list Home Assistant support in the catalog. IAMMETER WEM3080, IAMMETER WEM2067, IAMMETER WEM3050T, IAMMETER WEM3080T 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.
