Hi, I am trying to add generic way to update last item update time. I found two ways to do it: Write explicit rule for each item - working, but I really trying to avoid it Use last update group as follow (something I found in other discussion). The problem is that this is not working for me i…

@rlkoshak Thx, will take a look. Here is more detail with printouts. You can see the last time and the conversation failure. Thx for you help! rule "Last Update timestamp" when Item Last_Update received update then Last_Update.members.forEach[item | var lastUpdate = item.lastUpdate("infl…

I’ve succeed to fix the errors. WIll be happy to know if there is better / simpler way to do it. rule "Last Update timestamp" when Item Last_Update received update then Last_Update.members.forEach[item | var DateTime lastUpdate = item.lastUpdate("influxdb").toDateTime; var Calendar ca…

@rlkoshak Thx, you suggestion is working and simpler

[image] rlkoshak: In this case you may not need the Thread:sleep at all. If you do a sleep of 10 msec may be all you need. Even on a Pi, half a second is probably too long of a sleep for this rule. Thank you very much for your feedback. How does the sleep command in a rule actually influence…

[image] vossivossi: How does the sleep command in a rule actually influence the system behaviour? Will it only make the one rule wait or is the complete system in stillstand for that time? It only makes the one rule’s thread stop. But there are a limited number of threads available to run rul…

I have two type of items which I want to save the last update time for them. They are Number(s) and Switch(es). The problem is that Last_Update group can be used only for one of the types, or at least, when I add switches to the group it doesn’t work. Any suggestion how to handle this case? Thx! T…

You don’t say what currently doesn’t work.

See the [Type Conversion] (Type Conversions) article for examples of how to work with date times.
