Fixed IP during Installation/Restore

Summary

Provide users with the ability to fix an IP address during the Selorabox installation or restore process. This ensures that Home Assistant and dependent services (like MQTT) retain their previous IP addresses, maintaining communication with existing devices and services without manual reconfiguration.

Value

• Consistency: Devices and integrations (MQTT, etc.) that rely on specific IP addresses continue to work seamlessly after a restore.
• Ease of Use: Eliminates the need for users to hunt down and update IP addresses across their smart home ecosystem following a system migration or recovery.

Scope

• UI/UX in the Selorabox installer and restore wizard to specify a static IP.
• Validation to ensure the chosen IP is available and within the correct subnet.
• Backend implementation to apply and persist the static IP configuration.
