WattPanel-2X 120/240V split-phase homes Whole-home reference plus selected-circuit visibility You want a residential panel view with flexible CT bundle options. Service type, panel access, main and circuit CT scope WattPanel-3X Three-phase panels Panel and multi-circuit energy visibility You need a broader three-phase panel monitoring path. Three-phase service, CT scope, panel space, installation WattNet-1 Single-phase metering Compact energy-flow visibility A compact single-phase meter format matches the project. Service type, conductor and CT fit, mounting context WattNet-3 Three-phase metering Phase and energy data with CT options You need three-phase meter data rather than a larger panel monitor. Three-phase context, CT selection, antenna and installation WattNet-3R DIN-rail relay and metering Energy monitoring with a reviewed relay-control boundary The installation calls for DIN-rail metering and switching review. DIN space, relay load, CT size, wiring and control responsibility Application paths
Start with the place and task you need to monitor.
Product format follows the electrical context. A residential panel, three-phase panel, compact meter, and relay application do not use the same decision path.
Residential panels
See whole-home use and selected circuits.
WattPanel-2X is the starting point for supported 120/240V split-phase homes when the goal is a whole-home reference plus selected-circuit visibility.

Compact and DIN-rail formats
Match the form factor to the metering task.
WattNet-1 covers a compact single-phase path. WattNet-3R adds a DIN-rail relay format where load, wiring, and control responsibility require closer review.

Choose by electrical fit, not feature count.
A product can have the right app experience and still be wrong for the service, panel, conductor, CT, load, or installation location.
- 01Identify the electrical context.
Confirm split-phase, single-phase, or three-phase service from reliable documentation.
- 02Define the monitoring scope.
Decide whether you need whole-home, selected-circuit, phase, meter, or relay information.
- 03Check the physical fit.
Review panel or DIN space, conductor size, CT range, antenna placement, and installation access.
- 04Confirm the installation boundary.
Use final documentation and qualified guidance for wiring, load, local requirements, and safe installation.
Compatible accessories
Match CT clamps to the monitor and conductor.
CT clamps are accessories, not standalone energy products. Select them only after confirming the compatible monitor, conductor, current range, available space, and monitoring scope.

Energy monitoring questions
Which Grus monitor is the starting point for a typical 120/240V home?
Start with WattPanel-2X when the home uses a supported 120/240V split-phase service and the goal is whole-home plus selected-circuit visibility. Confirm the service, panel, and CT scope before ordering.
What is the difference between a panel monitor and a meter monitor?
Panel monitors are organized around panel-level and multi-circuit visibility. Compact meter products use a different form factor and installation context. Choose by electrical service, monitoring scope, CT fit, and installation plan rather than appearance.
Does every energy monitor control electrical loads?
No. Most products on this page are for energy visibility. WattNet-3R includes a relay path, but its load, wiring, switching purpose, and control responsibility must be reviewed before use.
Are CT clamps the same for every monitor and conductor?
No. CT selection depends on the compatible monitor, conductor, current range, available space, and intended monitoring scope. Review the selected product option and CT accessory guidance before ordering.
Can I use this category page as installation instructions?
No. This page supports product comparison. Use the final product manual and qualified electrical guidance for installation decisions and local requirements.
