Each Vue energy monitor supports up to 16 branch circuit sensors and up to 3 main line sensors. If your home has more circuits than one Vue can cover — or if you need to monitor both a main panel and a sub-panel — multiple Vues work together to give you a single unified view of your whole electrical system. This article covers the scenarios where a second Vue makes sense and which features in the Emporia app tie them together.

You have more than 16 branch circuits to monitor in one panel. Each Vue supports 16 branch circuits. Adding a second Vue in the same panel gives you 32 circuits total.

You have a main panel and a sub-panel. Each panel gets its own Vue. The app then understands the relationship between them so whole-home totals and sub-panel usage are calculated correctly.

You want to combine a Vue with a Vue Utility Connect. The Vue gives you circuit-level detail while the Utility Connect syncs directly with your utility meter for authoritative whole-home measurements.

You want to monitor Smart Plugs or EV Chargers alongside a Vue. Emporia Smart Plugs and EV Chargers have their own built-in monitoring. When paired with a Vue, the app can nest them under the Vue for a unified breakdown of home energy use.

The Emporia app has two related features for combining devices. Choosing the right one matters — using the wrong one will result in double-counted usage.

Combined Vues. Use this when two Vue devices are installed side by side in the same panel, monitoring independent circuits. Both devices contribute their circuit readings to a single unified view.

Nesting. Use this when one Vue monitors a main panel and another monitors a sub-panel fed by that main panel. The sub-panel Vue is "nested" under the main panel Vue so the app correctly attributes sub-panel consumption and avoids double-counting.

Nesting also works across device types: a Vue: Gen 3 can be nested with a Vue: Gen 2, a Utility Connect, a Smart Plug, or an EV Charger. The only requirement is that the devices are monitoring the same hierarchy of your system (upstream/downstream), not circuits or panels in parallel.

For a side-by-side comparison and a quick decision guide, see Combined Vues vs. Nesting: Which Feature to Use in the App section.

Each Vue in your setup needs its own kit with the following considerations:

Each Vue requires its own Wi-Fi connection and its own wire harness — these are not shared between devices.

Yes. Combined Vues and Nesting both work across generations. You can add a Vue: Gen 3 to a home already running a Vue: Gen 2, or nest one under the other if you have a main/sub-panel setup.

For either scenario, install each Vue device according to the standard installation guide, get both devices online in the Emporia app, then link them together using the Combined Vues or Nesting feature. For the full hardware install pattern, see Monitoring More Than 16 Circuits in the Setup and Installation section.
