How do I check that my Koralia WiFi device is updated to the most recent version?

Go directly to the main menu of the Hydor app and press “Upgrading devices”. Here you will see a list of the devices you have paired. If you press “INFO” you can view all pump information, including the current firmware and the available one.
If the Koralia WiFi device requires a firmware update, in the “ Upgrading devices ” menu the button on the right will be yellow and the words “UPDATE REQUIRED” will appear.
