Why don't my variables variate?

#1

1) Give a description of the problem
Everything works well except I cannot get the $currentEventDevice command to populate the actual device name in the arrival message.

2) What is the expected behavior?
Return [Presence Sensor 1] in lieu of $currentEventDevice in arrival message.

3) What is happening/not happening?
THe command executes and I get the push notification, but I get the $currentEventDevice variable, not my expected [Presense Sensor 1].

**4) Post a Green Snapshot of the piston![image|45x37]

5) Attach any logs (From ST IDE and by turning logging level to Full)

Any help is appreciated!

You need to concatenate the variable to the text, at the moment you are telling it to literally print the text “$currentEventDevice” which it is doing.

Try: concat("Welcome home, ", $currentEventDevice)
Or: "Welcome home, " + $currentEventDevice

If you want an example I modified your piston the backup code is: 36x4

I think there was an issue with variables inside a random() function… @bangali had a work around for it, somewhere in here.

Ha! Solved. Thank you my good man (or woman, I won’t judge).

I am now Noob version 1.1.
