@MobiSSS Cloud Server and all Local Servers are completely independent from each other.
Once you have logged in to your own Local Server, you need to clone your projects to it (from your Cloud server account).
Then modify the devices with the new IP address, directing the device to your Local Server instead of the Cloud as well as the auth codes for each project, which are generated by the server you are logged into (See https://github.com/blynkkk/blynk-server#app-and-sketch-changes).
Then, in the Admin page (See https://github.com/blynkkk/blynk-server#administration-ui), you will see your device, connection and other data accumulate over time.
