Hi,

probably the Powerbars will work correctly, but you need to configure the start numbering first. Therefore, select a Powerbar and click on configure (GCC) or click on the gear icon (App). By default, all Powerbars start with switch channel 1.

We will investigate the problem with the serial number. Do you have any other PAB devices connected? Do they have different serial numbers? And is the serial number of the Powerbar 6Es also the same, if you connect them separately?
