How do I connect meters in the topology to create a parent-child hierarchy?

You create parent-child meter relationships in the topology view. A parent meter represents the total (e.g., building main electricity meter) and child meters represent sub-measurements (e.g., tenant meters, floor meters).

Canvas view — drag to connect

1. Go to Analytics → Formula Meters and select the Canvas view
2. Find the parent meter card (the main/total meter)
3. Drag from the cyan circle at the bottom of the parent card to the cyan circle at the top of the child card
4. Release — the system creates the parent-child relationship and draws an arrow
5. The child meter now shows its topology level (L1 if directly under a main meter)

Table view — dropdown to connect

1. Switch to Table view
2. Find the child meter row
3. Click the "Parent Meter" column — a dropdown appears with all available meters
4. Select the parent meter from the list
5. The system updates the relationship and recalculates the hierarchy

Removing a connection

• Canvas: Click the arrow/connection line, then confirm deletion in the popup
• Table: Click the parent cell and select "None" or clear the selection

Rules the system enforces

• A meter cannot be its own parent
• Circular references are blocked (if A is parent of B, B cannot be parent of A)
• Each meter can have only one parent (but a parent can have multiple children)
• Parent and child must belong to the same account

Where to access: Analytics → Formula Meters → Canvas or Table view.
