Raspberry and two ESP8266

Hello every one, in my project i have to collect data from two motion sensors that are connected to 2 ESP8266, in my advanced version of my project I will add a raspberry pi to identify the nature of movement, and turn on the light only if it’s a human’s motion, so I have to create a dashboard for monitoring, to connect only rasp to cayenne i choose to make it as a MQTT broker, and 2 ESP8266 as mqtt clients , the question is how to read data from sensors on cayenne dashboards that are not directly connected two my raspberry rather they will send data through MQTT protocol.

are you familiar with node-red?

My post here goes over how to make an mqtt gateway with node-red.
