Hibrid project

[Psyos]

Good afternoon, I would like to know if you can help me with a project to be carried out. I needed a hybrid system, that is, control lights, blinds, gate motors via Home Assistant and at the same time manually in case the server is damaged. The server I want to use is KC868-Server16. 
I needed to know if I have to add the KC868-A16V3 module and subsequently relays. 
Thank you very much

server16 have 16 channel digital output. if you want use by home assistant, it's ok, just need add KC868-E16v2 extend relay module.
if your loads more than 16 channel, you can add KC868-A16v3 to extend the GPIO.
