I have an alert that emails us if an Item goes offline by setting an expiry metadata for 12 hr. and sending a refresh command to the Items in the group every 11 hrs. It works in some cases but other times it doesn’t.
So I created a test rule that sends an email if an Item does not change over a given time period. That seems to work. Now I want to use the same alert but monitor a group of sensors so I get an email if any of the sensors have not changed over a given period of time. So I replaced the block that had the Item in it with one to check the state of the Items in the group (get members of group > Flatline Group, in the script below) but it’s causing an error. I need to know the right way to have that block work correctly. Here’s the script:
Well that was pretty far into teh weeds for me. I have simplified this script for testing and out of that other thread, came up with this but it’s giving me an error that it’s failing to execute action 2:
I thought maybe it was because I wasn’t actually getting the state of the member first so I tried this but got the same result:
Yeah I saw that but that’s where I kind of got lost. I’m not familiar with how that is accomplished. Also, it looks like the state of the battery levels in that example is mapped to an ON/OFF state. I assume that above a certain level they are on and then off below that level. That won’t work for me because I’m trying to get notified if an item DOESN’T change over a given period of time.
I checked again and it works, the problem is that persistence takes almost 40 seconds to store the values, see my logfile

first i run the rule to see all 6 items in my group
i switched 5 of them
17 seconds after i changed the first item i run the rule and still 5 items show up
after 34 seconds i run the rule again and only the item which was not changed show up
Actually this isn’t working for me. I believe the problem is that this is looking for a change of state of the item. In this case the items in question are temp & humidity sensors so I’m looking for a change in the number or value but I don’t see a block for that?
I want this block, but to have “Number” or “value” in place of “state”:
When I try this with something like switches it works, but with these sensors it doesn’t. I dumbed it down to eliminate variables for testing and I’m still getting emails even though the temp is changing many times in 30 minutes:
The trigger for this rule is a time trigger set to every 30 min.
