New to the forums and SmartThings. I’ve had some programing experience in Java, but I am an Electrical Engineer by Major (Junior). This might be something ridiculously obvious that I am missing but I figured it didn’t hurt to post and introduce myself too! Basically trying to use the subscribe command to gather humidity readings in the future. I have typed it as shown below:
subscribe(humidity, “humidity”, showerEvent)
I go on to add:
def showerEvent(evt) {
//CODE HERE
}
For some reason I never get to the actually showerEvent function and it presumably hangs. I added a couple log.trace calls to figure out where my code starts and stops.
Any help would be greatly appreciated! And feel free to correct my vocabulary if I am naming/describing something wrong.

First, you said you added some tracing, but never mentioned what the live logging showed. Many would help you, but don’t have a device to measure humidity - so we are dependent on your logs to take educated guesses.
Second, when posting code in the forum, PLEASE surround it with [code] [/code] tags. For example:
[code]
your code pasted here
[/code]
(When you do it without the escaping I used, it’ll format it like this:
Thanks! Made that change to my code post. I have to run errands real quick but I will post the logs as soon as I am back. I probably need to add more tracers to pinpoint the issue so I’ll do that too before I post.
I forgot to state the purpose the code. Using a humidity sensor in the shower room I would like to take a humidity reading followed by another one after some delta time. I want to compare this delta humidity to a set value and if it is greater by a significant amount I want to send a push notification or sms.
Made those changes to the code:

Just a thought, as I’m dinking with a smart app looking at humidity sensors in the shower as well.
The potential issue with waiting x amount of time and trying to get a previous sample is just that, you are at the mercy of the reporting interval of the device…
Maybe consider using another humidity sensor in the house as your base line?, in my case I’m using the one in my thermostat as it’s not subject to localized changes.
Then I set a delta above the baseline humidity so once the shower humidity exceeds that threshold we fire the “do something” stuff…
This method doesn’t rely on calculating a rate of rise over time. if (currentShowerHumidity > (currentBaselineHumidity + triggerOffset)) makeItGobaby(), that type of thing.
Gotcha, I had a feeling there might be limitations like that. Thankfully, I have another temp/humidity sensor that I can use as a baseline. I’ll incorporate those changes see if that helps.
Nothing logs for the humidityevent when I use the virtual device unfortunately.
@rayzurbock has a custom smartapp that uses a humidity sensor to track trends so it can guess whether someone is taking a shower. Might be of interest.
Should be fairly easy to repurpose and add a sms/pushnotification event. I do have a question regarding the use of multiple sensors (if I wanted to go the simple compare the humidity of two sensors and take an action route): If I wanted to compare the humidity of one sensor to another can I simply subscribe them to the same event like so:
