Issues with String Comparisons

piston

#1

1) Give a description of the problem

I’ve got a simple action that turns off a light switch if another switch’s “LastEvent” string is not equal to Tap ▲▲. The logs seem to show that even though the string looks to match, it evaluates the comparison as true (as in, WebCoRE thinks that the two strings indeed do not match).

2) What is the expected behaviour?
WebCoRE evaluates the two strings as matching.

3) What is happening/not happening?
WebCoRE is evaluating the two strings as not matching.

4) Post a Green Snapshot of the pistonimage

5) Attach logs after turning logging level to Full

The issue here is this line:

+30ms ║║Comparison (string) Tap ▲▲ is_not (string) Tap ▲▲ = true (1ms)

Based on what I’m reading, it sure looks like this should evaluate to false, but is instead evaluating to true. Am I missing something here? Thanks!


#2

There is probably some special character or formatting that is not obvious. I suggest you store the lastEvent value into another variable and log it to see if you can tell the difference. You could also try an expression using contains to do the comparison also to alleviate problematic extraneous characters.
