Can I use a System Variable as a Trigger?

variables
triggers

#1

1) Give a description of the problem
I set up a trigger for when the $hour variable changes (i.e. once an hour), but the lightening bolt isn’t showing up and (surprise) the piston isn’t triggering once an hour.

2) What is the expected behavior?
Triggering

3) What is happening/not happening?
Not Triggering.

**4) Post a Green Snapshot of the piston


#2

When I tested this:
temp

The top banner says:

Basically like you said, no lightning bolt, no trigger…

Even when I forced a subscription like you did, I get the same results. (nothing)

I even tried this:
temp
but still nothing…

I have used system variables as conditions all the time (they work well), but have not tried as a trigger until today… You might have to rethink your logic, and simply have that section run every hour at X minutes past the hour…


#3

I figured. I just wanted to make sure that I wasn’t missing something obvious. I know that there are probably a dozen other ways to accomplish this.
