All nodes i.e. temperature sensors, boiler controller, zone controller, blinds and lighting controller etc. are scattered around the house that are responsible for controlling light, heating, blinds and other IOT devices serves very little purpose if we can not communicate with them or pass some instructions.
Most of the time these devices are battery powered and even ones with main powered don’t communicate through home WiFi and for the battery powered nodes WiFi isn’t the option due to the fact how WiFi works, most of the time these IOT devices are connected through low powered (nRF24L01) trans-receiver but on same time all these IOT nodes need to communicate with controller.
How we can communicate and pass some instructions to these IOT devices/nodes to have control on them? the simple solution that bridge the both worlds (nRF24L01 and WiFi) and to do this we need a device that can communicate to all IOT devices/nodes over low power trans-receiver (nRF24L01) and to our smart home controller over Wi-Fi.
You may have heard about it as Smart Home Gateway or simply IOT Gateway but its same thing so ultimately it communicate with all the nodes and on other side connect with your home automation controller either over WiFi, Ethernet or over serial port.
