Restarting My SkyConnect Zigbee Network: How to Prevent Automatic Device Reconnections?

Hi, today I tried to reset my SkyConnect Zigbee stick and delete my existing network. Every time I try, all devices reappear after reinstalling, but they are not reachable. I’ve already reinstalled the SkyConnect software from the website. I want to set up the entire network from scratch, got 33 device.

How can I do this without all devices automatically reconnecting?
