The logic of the application is that after establishing the mqtt connection, it sends data, that is, tags, through a single "topic".


if(data=="tag1"){
lamp1 on
}

if(data=="tag2"){
lamp1 off
}
Note that tag1 and tag2 represent on and off for you. And knowing this, you can give whatever name you want to tag1 and tag2.

For example, button1's labels might be on1 and off1. Button 2 labels can be on2 off2, you can use the pins with as many conditions as you want. You can also use more esp with the same mqtt settings.

Use more pins by adding more conditions this way.

Simple and easy.
