Is it possible to have several systems on the same wifi?

I am completely new to Home Assistant and are running your project on habits. In this connection, I need to log infomations from a number of users on the same network. My question is whether you can have more raspberrey pi’s with hassio on the same network without causing problems?

What does this mean?

It is a research study that are looking at human habits.

You can have more than one installation of HA on the same network. You just need to ensure they are using different IP’s (obviously). It may get hairy if they are trying to control the same device, tho.

Also they will all also auto discover items on your lan.
