- Here, I try to show how to generate random data in two ways for two types of temperature. One is by the node which is called a random node and another one is the function node. We have to write code in JavaScript. And I make a function that when I select the manual mode that time the active and inactive button will work. But when I select schedule mode that time the button means the active and inactive buttons will not work. In the meantime, I use a colour function node when I select manual and change the button, it will also change the colour status. We can easily find out what is going on in the system.

- I also created an alarm dashboard where I tried to show the real status of the devices.
- Here is the alarm of node-red flow.

- If the temperature range is below of 50 °C then it will show normal mode and the colour will be lime. If the temperature range is upto 50 °C to 70 °C, then it will show major and the colour will be yellow. If the temperature ranges are more than 70 °C and below 100 °C then it will turn red clour.
