Quick Decision Guide
Use Combined Vues when:
You have multiple 200A panels running in parallel
You need to monitor 17+ circuits in a single panel using multiple Vues
You have multiple independent panels that don't feed each other
Use Nesting when:
You have a main panel with a sub-panel
The sub-panel draws power through the main panel
You want to track sub-panel usage separately while preventing double-counting
What's the Difference?
Vue Nesting
Nesting is designed for hierarchical power relationships - when one panel (sub-panel) draws its power through another panel (main panel).
The sub-panel Vue is "nested" under the main panel Vue. The app shows the relationship between the two panels and prevents double-counting since sub-panel energy is already included in the main panel's mains reading.
Combined Vues
Combined Vues is designed for parallel or independent monitoring - when you need to aggregate energy data from multiple Vues that don't have a hierarchical relationship (usage in parallel).
Multiple Vues are linked into one unified view, with all circuits appearing in a single sorted (or customized sortable) list. Aggregated totals show combined totals (from mains sensors) in watts, kWh, cost, and net usage across all devices.
When to Use Each Feature
Main Panel + Sub-Panel → Use Nesting
Your Setup:
Main electrical panel with a Vue installed
Sub-panel that draws power from a breaker in the main panel
Vue installed on the sub-panel
Why Nesting: The sub-panel gets its power from the main panel, so its energy usage is already included in the main panel's mains reading. Nesting shows this relationship correctly and prevents double-counting.
Parallel Panels → Use Combined Vues
Your Setup:
Multiple 200A panels running in parallel
Each panel receives power independently from the meter
Vue installed on each panel
Why Combined Vues: Both panels are fed independently from the meter, so there's no hierarchical relationship. Combined Vues aggregates the readings from both panels to show your true whole-home energy usage.
Single Panel with 17+ Circuits → Use Combined Vues
Your Setup:
One large electrical panel with more than 16 circuits
Two Vues installed in the same panel to monitor all circuits
Why Combined Vues: Install the Primary Vue with 200A mains CTs plus up to 16 circuit CTs. Install the second Vue with only circuit CTs (no mains CTs). Combined Vues shows all circuits in one unified list with accurate whole-panel totals.
Important: Only install mains CTs on the Primary Vue in this scenario. If both Vues have mains CTs in the same panel, you'll measure total usage twice.
Key Takeaways
Nesting is for hierarchical relationships (main → sub-panel)
Combined Vues is for parallel or independent monitoring
Using the wrong feature can lead to inaccurate readings through double-counting
When in doubt about your electrical configuration, consult with a licensed electrician
