Bug in "Notify If Left Unlocked”?

I am trying to use the Notify if Unlocked code and it works, with the exception of sending the optional SMS message…and I can’t figure out what the issue is. The error message being logged is as follows.

c0ba4b58-d68c-49f3-9085-242f2e847050 10:50:45 AM CST: error groovy.lang.MissingMethodException: No signature of method: script14177118442451333570032.sendSMS() is applicable for argument types: (java.lang.String, org.codehaus.groovy.runtime.GStringImpl) values: [(999) 999-9999, Breezeway Door is left unlocked and closed for more than 1 minutes.]

Anyone have any recommendations/thoughts on what the issue is here?

I’ve copied the code below for reference. Any help is appreciated.

Thanks in advance. - Kevin

Thanks Matt! I’ll give it a try.

Loaded it up but am getting the following error…and no notifications.

7a078942-e32a-40cc-98b0-bc1e132d1745 8:01:24 AM CST: error java.lang.NullPointerException: Cannot execute null+null @ line 186

Please see this thread

I hadn’t actually loaded this either and now that I did. I get the same error. I’m sure he’ll fix it.

Fixed it with the following updated runNotifyAt function.

private def runNotifyAt(timeMs) {

def currentTime = now()
def date = new Date(currentTime + state.repeatMs)

runOnce(date, taskNotify)
log.trace "taskNotify scheduled to run at ${date}"


New version 1.0.2 is available…working great!
