There is only one way to make sure about the total number of devices in a project: open the 'Devices' panel by clicking Workplace>Open New Panel>Devices.
Principally speaking, every device entry that is shown under the 'Devices' panel, regardless of the amount of channels or functionality it has, is counted as one device.
- Example 1: one switching actuator with 8 channels is counted as one device.
- Example 2: one KNX/DALI gateway that can handle 64 DALI ballasts is counted as one device.
If there are 'parked' or 'unlinked' devices in a project, those are counted as well.
