Hi, thanks for your ideas & comments. Well, I really like the idea of the design patterns and therefore I am happy I can contribute. I am very new to openhab and therefore have to get around some aspects of the programming model for rules. With your hints I could rephrase the rules a bit, but it is…

My bad. You don’t have to import DateTime, but you do need to import java.util.Map.

I tried that already, but it still gives the following errors: 2019-02-07 19:43:25.015 [ERROR] [ntime.internal.engine.ExecuteRuleJob] - Error during the execution of rule 'temp2': cannot invoke method public abstract java.lang.Object java.util.Map.get(java.lang.Object) on null 2019-02-07 19:43:40.0…

You have to pass the maps into the lambdas. Global lambdas do not have a context. They cannot see any other global vals or vars. You must pass them as arguments.

Ahh, ok, one needs to know that as well. :wink: Then finally, I finished the sample, but I am still having one issue regarding the call of sendCommand(String, String): import java.util.Map val Map<String, Timer> Timers = newHashMap val Map<String, DateTime> Timestamps = newHashMap val SwitchPre…

Solved it, by changing to sendCommand(id + "ShortPress", "ON") // etc. after reading your post at: sendCommand() Documentation :slight_smile: Obvious, but I missed it, that the call clearly needs two Strings. :wink:

Updated the initial post and rules, plus added an application example for a dimmer switch.

Updated the example and introduced a stop for the rescheduler. So after 10 times, the long press action will stop to reschedule itself. This is due to the fact, that sometimes the RELEASE was not received by openhab and led to endless rescheduling. My bad. :slight_smile:

I’m going through all of the DP postings and posting at a minimum Python versions of the code. Here is a Python version of the above. I never used this DP so this code may contain some errors. Please let me know if you encounter any. from org.joda.time import DateTime from core.actions import Scrip…

I’ve tried the above scripts, but the could not be parsed correctly. Therefore, I remain on my versions. I am currently about to extend the behavior such that one can use it for the following scenarios: Use as regular switch (short press and long press: actionset1) Use as double switch (short pres…

My apologies.. I read too fast and jumped to conclusions. I had thought the latest code you posted, which is full of issues, was an evolution of the code in the OP and that it also had those errors.

BTW, here is a related tutorial for a Jython version (there is also a link in it to a DSL version)…
