Are there any recommendations regarding Wi-Fi configurations?

Currently a DEVIreg™ Smart Thermostat/Switch can only store one Wi-Fi configuration (SSID+PASSWORD). In order to prevent that the installer must re-configure all DEVIreg™ Smart thermostats/switches when the Wi-Fi password change, the DEVIreg™ Smart thermostat/switch needs to be able to store a list of up to 5 Wi-Fi configurations. If the DEVIreg™ Smart thermostat/switch fails to connect to one Wi-Fi (both SSID and password required to make it unique), it should try the next.
