occasionally I come back to OH (I first tried OH2, then OH2.5, and now I want to give OH3 a try), but I usually get to a point where I am literally overwhelmed by the steep learning curve.
I think I’ve got the basics of the semantic model: I managed to create my locations/equipment/points and make them (more or less) work (I’m still experimenting).
What I’m really struggling with is rollershutters and scripts/rules.
I managed to make RS appear in the dashboard (location/equipment/properties), and when I push UP/DOWN/STOP buttons, everything works great. I alse managed to make a non semantic group to contain all of the RS in my house, so that I can open or close all of them with a button.
What I really can’t do is to make some basic scripts to open just a bit of a RS (my RS don’t track position, so I have to be creative).
I think I have 2 ways:
make some sort of script/rule to send command UP, then wait for n seconds, then send command STOP
use the binding properties (OpenWebNet (BTicino/Legrand) Binding) which should emulate the position tracking with timing, sending a percent opening command.
In both cases I can’t figure how to do this…I’m making a big mess with scripting language (blockly/ECMA/DSL???). I’ve already read the site guide, searched the forums, viewed tons of youtube videos, but I’m exactly at THAT point, struggling with confusion
(I did not specify that I’m certanly not a programmer)
That’s interesting…this could help me setting timers (maybe I don’t need the entire rule, but there are parts I need indeed).
I still don’t get what a “proxy” is in the example, though…could it be a fake switch?
I’m going to make some tests.
One more question: what’s in general the right way to pass a position parameter to a rollershutter?
Why is RollerShutter.sendCommand(50) wrong?
Commands don’t really care about Points and Equipment in any way. They operate on Items.
If you want your Group Items to accept Rollershutter commands and pass along to members, I think you need to make your Groups to be subtype Rollershutter.
You don’t need any aggregation function just to distribute commands.
If you send a command and it doesn’t do anything you expect, time to look into channels/Thing/binding path. None of that cares about Points or equipment either.
Looking in your events.log may give a clearer view of who is doing what.
mmm…this is unclear…aren’t equipments and points, items?
…if I go under Items section, I find them there…and if I create a rule, it allows me to pick up one of them…
If they are not items, how am I supposed to interact with them with rules?
That’s what I’ve done (if I get what you are saying): as a matter of fact, i can see UP/STOP/DOWN commands for the group gRS in the overview page, and pushing a button gives the command to all of my RS.
So…I made some tests… (quite) everything seems to work correctly:
I managed to create another link (point) with dimmer properties to a single rollershutter, and the binding correctly send the command to open a % of the rollershutter simply dragging the dimmer point (from which I deduce that the basic configuration is correct and the binding is working correctly)
I managed to create a rule in the UI where I set to close all of my rollershutters (sending the command to gRS group) at a given time (“when the time is 22.30 then send command DOWN to gRS”) (from which I deduce the group is correctly set)
What I still can’t do is to send a command via script…any example? …scripting is still a mistery
I have a Python programm running taking care of the rollershutter movements and functioning as interface to the rollershutter remote(s). I took measurements of the closing times for each roller shutter and put them into this programm. With an MQTT transfer I am telling the programm to which percentage I like to close a rollershutter. This is done by a command to a item in openHAB.
Thanks to everyone.
I finally managed to make it properly work. Everithing was done correctlyt, except for the rules: I used ECMA instead of DSL language. Now I can simply send an item.sendCommand(75) to close 75% my Rollershutter.
For sure @rossko57 pointed me to the right direction making me understand a bit more the OH3 structure.
