Is there a way to view the device values saved using "capture attributes"

[markplewis]

1) Give a description of the problem
I am debugging a piston and need to see the attributes associated with a device as they’re saved (specifically, level and switch state). I capture this info to a variable but cannot figure out how look at the actual values. If I text the variable to myself, the value is always “Empty device list.” Is there a way to see what values are being captured?

2) What is the expected behavior?
Lights are off. Piston runs, captures state (which is off), turns lights on waits 2 minutes and then restores state, which should be off. Log shows piston restoring lights to 100%, not 0%. I need view the values the piston is grabbing when it runs.

3) What is happening/not happening?
Device state doesn’t appear to be being restored properly. I want to see what values are being captured so I know what should be restored.

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

**5) Attach any logs
I’ve bolded the area in the log where I set the variable. It’s those values that I want to expose and look at.

I don’t think webcore exposes that to us so I’d probably try the long way around by logging [deviceName: attribute] during the capture and restore.

[markplewis]

Thanks @eibyer. That seems like a good approach. Unfortunately, I get an error when I try to log the values. I’m not sure if it’s something wrong in the way I’ve used the log statement or something else.

Does anyone have any ideas what I’m doing wrong and how I can log the values I need to look at?

And the updated piston with logging:

[eibyer]

Only need one colon in the [deviceName: attribute]

[markplewis]

I deleted all but one log statement and removed the second colon from the remaining log statement. I’m still getting the error. When I open the task, I can see things are evaluating properly (the switch was off when I ran the piston) but I get an error when the piston runs.

Here’s the error:

Any suggestions are appreciated.

[eibyer]

Ooh, under Log type, leave it as info, use Expression instead of Value for the next field.

[markplewis]

That was it. Thank you.
