Wired Video Doorbell T8203 (S330) - Homebase 3 Compatible?

I have a Wired T8203 (S330) doorbell that says its Homebase 3 compatible. Why does it need to connect to my home WIFI and not my Homebase 3 wifi?

Is there a video doorbell that connects strictly to the Homebase 3 WIFI?

Hi, I would contact eufy support to see if it’s compatible yet.
