You have different options to have several Wi-Fi Networks with your mesh units: 
• You can set up your mesh unit as access points instead of mesh nodes.
• You can deactivate the band steering option of your device that creates a single Wi-Fi Network for the 2.4G or 5G bands. 
• You can also configure a guest network.

We advise you to set up a guest network if you need to have several Wi-Fi networks at home.
