In this video tutorial we will create a very simple controllable MQTT sensor that you can use in IOT projects to simulate a two state sensors like lights,doors etc
The sensor can be controlled across the Internet by sending simple MQTT commands.
We look at choosing suitable topic prefixes for sensor state and sensor commands to allow control of multiple sensors.

We examine the function node in detail and I show you the function node extracts commands and sends status information.
