60m2 Smart apartment automation project

[beemasport]

Hello,

I've started and moved the project.
The box is 95% complete.
32 chanels in total.
16+8 omron relay boards + 8 DC contacotrs.
14 relays will control lights in the apartment;
2 will control the exhaust valves for ease of ventiolation;
8 relay will control lower consumption appliances ( according to manual up to 16A) the 8 DC contacors will control higher consumption appliances ( according to manual up to 20A) .

1. Main controller:Kingcony KC868-SERVER
   
2. Slave controller:Kingcony KC868-A16
   
3. Relay extender 1:Kingcony KC868-E16 v2
   Note: This board is very convenent the NC ports allows for ventilation valves to stay closed all the time, when the relay is on valves will open with exhaust fans)This might have more uses but as a brand new DIY-er i did not find more uses.
   
4. Relay extender 2:Kingcony KC868-E8
   
5. DC contact : x8 
   Each individual controlled line has a separate live wire.(When having conversation with proffesional electricians, i got the answer that nobody does that because its a waste of wire)
   Size of the box is 80x60cm.
