What does hotspot generated by the Gateway mean? Why is the app asking me to access the Gateway’s Wi-Fi network?

If connectivity is not available, the Gateway automatically generates a hotspot network (its own Wi-Fi network). This network is not connected to the Caleffi cloud, but is a local network that acts as a means of communication between the app and the Gateway if the internet network is not available. When accessing the Gateway’s hotspot network, not all of the app’s features are available, so we recommend restoring the internet connection as soon as possible. The Gateway will connect to the network automatically when connectivity is restored.
