Grouping devices

Go to the "Groups" tab in the commissioning interface.

The grouping function allows you to schematically organize the devices as they are connected to the electrical groups in your building as shown in the first figure.

You can compare this with the single-wire diagram of your building.

You need to do this so that the SmartgridOne Controller knows how everything is connected. It can for example take the maximum current of a group into account.

There are two configuration options:

1. Simple groups (default)
2. Advanced groups

Simple groups

Simple groups is the default option. With this option, the SmartgridOne Controller will automatically use the first energy meter you connect as the grid energy meter, and place all devices in one group. You can compare this to an installation with one energy meter and one distribution board.

Advanced groups

Advanced groups can be used for more complex installations. Here you have complete freedom to configure how the electrical installation is structured.

Advanced groups can also aggregate several physical energy meters that together represent one shared control boundary, or calculate the unmetered remainder below a real meter. See Virtual energy meters and meter aggregation before configuring these topologies.

Creating a new group

1. Choose "Create a new device group" from the dropdown menu.
2. Choose a group name and type. The following types are available:
   • Switchboard (distribution board): This corresponds to an electrical distribution board.
   • Solar installation (PV installation): This corresponds to a group of PV inverters, and is specifically intended for monitoring PV installations.

Assigning an energy meter to a group or device

1. Choose "Assign an energy meter to a device or a group" from the dropdown menu.
2. Choose the energy meter you want to assign.
3. Choose the group to which you want to assign it.
4. Click on "Assign energy meter".

Enable Add a virtual energy submeter only when you want the controller to calculate the part measured by the real parent meter that is not covered by its other known child branches.

Adding devices to a group

1. Choose "Manage existing groups" from the dropdown menu.
2. Choose the group to which you want to add devices.
3. Select the device you want to add.
4. Click on "Add member".

Adding a subgroup

1. Create a new group as described in "Creating a new group"
2. Choose "Manage existing groups" from the dropdown menu.
3. Select the group to which you want to add the subgroup.
4. Choose the subgroup you want to add.
5. Click on "Add member".
