I am using openHAB 3.0.1 via my browser to its Main UI and continue to stumble around wrt Javascript rule & script writing. I have seen recommendations that I use the method myItem.sendCommand(ON) rather than static function events.sendCommand(myName, ON). My problem is that I have not successfully mapped an item’s name to its corresponding item object. I have tried to use ir(myName) which (I believe) is the same as ScriptServiceUtil.getItemRegistry().getItem(myName), but the resulting object does not have the method I am looking for.
So any insight regarding getting an item with a sendCommand method is appreciated. Or, perhaps the advice is stale?
Thank you! You have brought immense clarity to my understanding, much like being whacked with a 2⨯4 brings clarity regarding carpentry.
I’m beginning to believe DSL is the only viable mechanism for custom scripts and that Main UI, Javascript, and Python are really neat demos, but not a lot more. My next quest is to figure out what DSL stands for.
Yes, I have been reading (a lot for me) about openHab’s DSL, Python, and Javascript. I’d like to think that my assertion is more a reasoned conclusion than a leap. Nonetheless, I’ll continue to pursue various aspects with a mostly open mind. Your answer has been most helpful in that it narrows the possibilities while better defining my mental model of what openHab provides.
My problem with being a newcomer is that documented information seems non-existent. So I spend a lot time with google, grep, find, and diff. Then I risk wasting a forum member’s time with my queries.
Reading forum threads about the differences between OH 2.x and 3.0 when the new-comer is just trying to grasp a simple fundamental with a simple working example is like reading about the differences between Beowulf and The Queen’s English when a new comer needs directions to the nearest transit stop.
Again, thank you for your response. I really appreciate it.
