I wrote a DSL rule and noticed the following couple issues. State is not import org.openhab.core.types.State By default, State seems to resolve to a non-openHab class that doesn’t even have a toString object: 2020-10-26 22:11:34.744 [ERROR] [internal.handler.ScriptActionHandler] - Script execution…

Yes, everything in DSL in the “global” context (actually only global within this rules file) cannot “see” other global objects… So when you call function X from a rule, and it needs to use function Y, you must pass a reference to that in the call. Oh thanks for that explanation. That also means I…

[image] Frenchman: I wish one could write things like this as simple extensions, say in JavaScript or whatever that could then be used by the whole framework. Yes, others are ahead of you. This one of the reasons that OH3 has a new rule engine and the jython implementation features libraries…

Yes, others are ahead of you. I am sure! openHAB is pretty impressive. Okay, let’s work on [the notion of multiple taps]. What are you trying to achieve? Ignore how you think of going about it. What’s the starting point here? You are receiving trigger events from a binding, or state updates t…

Alright, I have to guess that this technology updates Item to ON when pressed and updates to OFF when released. They do not all work like that. // global timer var Timer buttonTimer = null rule "detect press" when Item myButton changed to ON then logInfo("test", "button pressed, don't know…

Alright this may work, but who wants to copy/paste and edit this every time they want to handle a double tap? In my current rules file, I have lots of such cases, and they all are a two-lines readable rule calling one function, not ten lines of code, that, if I came up with a better mousetrap, or a …

[image] Frenchman: who wants to copy/paste and edit this every time they want to handle a double tap? Why, does it cost you very much? It’s a home automation system. Why isn’t the button doing double tap detection for you? Many do. How many of these limited feature buttons did you buy? T…

When you have specific problems, people will be happy to help. I see that and appreciate it. Thanks.

You can get the name of the Item that triggered the rule with triggeringItem.name. But notice I said the name, not the Item itself as the key. Got it. Names are fine, they’re unique too. I haven’t run into that issue in my function (the key to my map is a SwitchItem) but I believe you …
