This is a good summary of the differences: [https://stackoverflow.com/a/359509/2117239](https://stackoverflow.com/a/359509/2117239)

In short, === is a strict type and value test. In your code, that means the Active property must be a Number type and must have the value 0.

The == comparison doesn't do strict type checking. So it will accept a much wider set of values. For example: `"0"==0`. But also `false==0` and other possibly unexpected results. This is why you get a warning.

So the real question is what exactly is the value _and_ type of the `msg.payload[i].Active` property. If you pass it to the debug sidebar, it should give you hint you need.
