I want to experiment how MQTT works. But it is a big black box for me. I know that mqtt is a protocol. You need a broker(server) to use this protocol. I thought that a device is a MQTT client. But when I search the store I find different apps. Which do i need and what can I do with it.
The first things i wanted to try is how i can manage a device f.i. a Sonos speaker or a Hue bulb.
Second i want to try to get weather data from openweather with MQTT and how can i get the data into a variable.
Would be nice to get some help and some examples.
The topic for the MQTT app is so huge that it is a little to much in the beginning.
