More than 8 GB received in one day, is this normal?

My hassio says it receives about 8 GB of data through the ethernet port in one day, is this ok?

Do you have IP cameras?

I do but my cameras are connected but hidden in the UI of HA, so they are not really streaming anything during the day… maybe…

I think that HA is connecting to the cameras and receiving the stream even if they are not displayed in the UI.

I see… maybe could be also the Google Assistant addon and component constantly listening? Who knows…
