The devices can still be discovered on your network. You can check your router's status for the assigned IP and see which Shelly devices are present and their IP address.
Another way is to check the IP address of Shelly devices by using Shelly App. To do this, click on the "Discovered devices" section. There you will show all devices that are connected to the same network as your phone.
You can also use our desktop app called Shelly Device Finder, which you can download at: https://www.shelly.cloud/en-bg/support-knowledge/support
