I am plan to make home automation system for my college project and I am also interested to implement in my home. I have to connect lots of relays and sensor then I use lots of nodemcu each nodemcu is contain several realys and sensors. I have mesh network of nodemcu because every nodemcu is connect to router because router signal is limited range. I have plan to use home assistant os to control the relays. I have use node-red for program the nodemcu and influxDb is used as a database to store all the sensor value and relays status and I use Grafana is used as a data visualization tool for attractive dashboard. In home automation system there are several festures 1.manual control if home automation system is not working then it is work as normal. 2 App control 3. Automate all the electric appliances . The question is that how to use mesh network of nodemcu to control all relays and read sensor values. 2. How to implement mqtt protocol in home automation system

Hi, about q1. how to use mesh network of nodemcu to control all relays and read sensor values--> you need coding every nodemcu in your mesh network when receive broadcast commands(control relays and sensors) that is a big work. You can use JSON to send and receive commands and parse it. about q2. MQTT in HA --> Sorry, I have no idea.

Hi! I 'm going to explore MESH in ESP32. Could you please give me a link of projects source code? Thank you so much!

Hi, I used painless mesh sample code to do it. and Put my project into my blog!
