While it’s not suggested to use BlueSmart mia without WiFi connection, you can still use certain functions of the product when you are not connected to WiFi as long as the product is set up successfully. The temperature alert, feeding reminder, angle alert, feeding duration, and feeding amount features will still function but they are limited. Besides the feeding amount (voice recognition feature), all other data will be saved while offline for up to 8 feedings. For the feeding amount, only the latest 2 voice inputs will be saved. This data will be uploaded to your smartphone app once your device is connected to WiFi.
