When setting up the smart home system using WIFI as the core network infrastructure, it is important to split the surfing traffic and smart home traffic. This will ensure that the smart switches respond timely. For my smart home setup, I have used 2 Asus routers (RT-AC1200G+ & RT- AC68U), one is configured as the main the other configured as the slave. There is no reason why a particular model is chosen as it is based on what I have on-hand but it is better to have dual-band routers because I will have 4 separate bands (Two 5Ghz and two 2.4 GHz) of network bandwidth. The router is configured as a Master-slave mode with different subnets and network route is added to make sure that the traffic can flow both ways. The smart switches are all connected to a dedicated 2.4 GHz bandwidth and the remaining 3 bands are for normal surfing. For normal surfing, in order to the client devices to automatic connect to the strongest signal frequency...
