Yes. Ato must remain plugged in to function properly and to always be available for the User.
The device does not include an internal battery, as it was designed to stay in a fixed place within the home and provide continuous support.
Why is it better for Ato to stay plugged in?
When Ato remains permanently connected to power:
It is ready to respond at any time
It can play reminders without interruption
It allows messages to be sent and received consistently
It remains available in case of any important situation
This provides greater peace of mind for both the User and their family, since Ato does not rely on someone remembering to charge it or checking battery levels.
Recommendation
Place Ato in a stable area of the home where it can remain plugged in and connected to a reliable Wi-Fi signal. This ensures it is always ready to support and respond when needed.
