Split-Phase Home Energy Monitor
See whole-home and selected-circuit usage with WattPanel-2X, then check service, panel, and CT fit before choosing a kit.
Start with fit. Then review current WattPanel-2X kits, live pricing, and the installation boundary before ordering.
Review product fit, support paths, and the right next step before making a purchase decision.
Confirm split-phase fit, then choose the product bundle.
Use the fit guide first when service type or panel context is unclear. Move to WattPanel-2X when the monitoring goal and electrical fit are understood.

Shopify provides the current variant and price status. Choose a bundle only after confirming split-phase service, panel access, CT scope, and installation requirements.
Check four things before you choose a kit.
Fit depends on the service type, available panel space, CT scope, connectivity, and installation responsibility.
Use visible labels, existing documents, and qualified guidance. Do not open a panel or handle wiring just to make a buying decision.
- Confirm a supported 120/240V split-phase service.
- Check panel space and the intended main or circuit CT scope.
- Plan Wi-Fi and antenna placement around the panel location.
- Confirm whether qualified installation and local rule review are required.
Understand where the measurements come from.
Main CTs provide the whole-home reference while circuit CT scope depends on the selected kit and intended panel layout.
The system provides visibility into usage patterns. It is not a switching device, a guaranteed bill-savings product, or a replacement for electrical diagnosis.
- Choose a kit for the monitoring scope you need.
- Use the app to review current and historical patterns.
- Use final product documentation for installation decisions.

Energy monitoring questions
What type of home energy monitor should I consider?
Start with the monitor that matches your visibility goal, supported service type, panel context, sensor requirements and installation boundary.
Is an energy monitor mainly for visibility or control?
It is mainly a visibility product unless final product documentation states specific control features. Do not treat monitoring as direct load control.
What should I check before buying a panel energy monitor?
Check service type, panel access, sensor requirements, app/connectivity support, manual status and whether qualified installation is needed.
Can Grus guarantee lower electricity bills?
No. Grus does not guarantee savings. Energy data can support decisions, but outcomes depend on the home and user actions.
