No. Don’t do it. Unifi is great for WiFi/networking but all other produtcs are overpriced and just short of good. They will also randomly kill it just before it gets better. Same is true for their network gear it just doesn’t matter since they create replacement.
Dahua VTO and VDO is good product that is well supported in HA.
Look at ESP32-S3-Box 3. I’m sure you can make something with that if you can find them or look for other esp based prebuilt or diy intercom. I used Alexa for years but am trying to move away to something local. I got 5 Atom Echos and will see if I can make this work.
