Set Device to Expression - What am I doing wrong?

[SeattleDavid]

I am having troubles getting the "Set Device to Expression" to work in conjunction with device references...

The Value of "Light - Beam Art - Upper Red (021)..." is 41.

I would expect the Device to be set to 20, which is "Round(41 / 2)" but it is not changing at all.

If I hard code the value to something like 13 then it does change, so I know that the Event is triggering.

I suspect the problem is something to do with my syntax in:

Round($$DVR:285:/2)

But I am new and don't see where the error is. Any thoughts?

Here are some screen clippings so you can see exactly what I have:


Here is the Virtual Device with Ref ID 285:

Try Round($$DVR:285: /2, 0). The 0 is the number of decimal places, making the result an integer.

Yes, thank you, that solved the problem.

I wrongly assumed that (Round) would default to an Integer rounding. Apparently not.

Again, thank you. It worked.

FYI, some documentation about operators and functions for expressions: I have just added a topic about available operators and expressions: https://forums.homeseer.com/forum/ul...in-easytrigger
