Trigger script when pressing a wall switch

[dannybloe]

Hi folks,

Right now I have a zwave wall switch that triggers a scene. In the scene I switch off a dozen lights in the house. Because it takes an enormous amount of time before all the lights go out (sometimes almost a minute!!) I was thinking to try it with a lua script.

Basically, that's is where my experiment ended. It seems to be possible to trigger a script when the scene is activated using script:// but there seem to be no documentation at all on how to use this (do not try to search for 'script://'). I suspect that Domoticz tries to run a OS script located at the path behind script:// but it only gives me errors when I try to link it to a lua script. So that doesn't help me much.

So, the only thing I can come up with then is to create a dummy switch, turn that on in my scene, have a lua script mydummyswitch.lua and use that. Or is there a easier way to do this?

You could start with wiki: https://www.domoticz.com/wiki/Events

Ehm... I know.. but it doesn't tell me how to trigger a script when a scene is activated or I am blind. I can't find any documentation on how the 'script://' fields work.

[alfred_j_kwak]

You don't need scene with Lua. You can create dummy switch and use that to activate script. If you use switch then you don't need script://.... at all.

I believe I need a scene or a group otherwise I cannot link the physical z-wave wall-switch to something in Domoticz:

wall switch press > trigger a scene > set dummy switch to on > trigger script_device_dummyswitch.lua

Or is there a way to trigger a dummy switch when I press my zwave switch? I haven't found a way to do that yet.

For example - here is a page where you could find syntax for running script with switch. viewtopic.php?f=23&t=9176
I suppose that after you have working solution, then you could write guide into wiki.

Problem with that approach is that you can't run lua scripts and you don't get all the states from Domoticz. You have to do loads of curls to get the current states and curl new states etc.
So why not put a script in scripts/lua with the name: script_myscenename.lua and have that triggered when the scene is activated. Or script_groupname.lua.

Or is that already possible?

[alfred_j_kwak]

When you read that wiki-page there is said: "To switch a scene or group, put prefix 'Scene:' or 'Group:' in front of the scene name. Note that it is not possible to check the state of a scene or group, since that is not its intended use."

As you noticed english is not my primary language so it might be that I'm not answering to your question - so I rest my case. Sorry.

Alfred.. I don't want to switch a group or a scene! Please read my post. It is the other way round: I want to trigger a script when a scene is triggered by a button and preferable a LUA script.

[dannybloe]

alfred.. thanks anyway

Anyway.. I managed to trigger a lua script via dummy switch route and unfortunately it is still slow. Turning off a group of zwave devices just takes an irregular long time. Maybe it's just zwave or maybe OpenZwave. I don't know. Funny is that turning on a group of switches seems to be a lot faster.

Maybe I should try to live with it and trust that eventually all the lights will go out. It's just that I don't want to come downstairs the next morning to learn that some commands never reached a light and that they stayed on all night.

My Z-Wave network is about the same size as yours and I too have delays. All the lights go out after each other. Can take about 30 seconds for a single floor.
Until now they are always off when I get up in the morning so I don't really care.
Delay is worse for devices that are not directly connected to the controller, which is logical as the commands are relayed via the mesh network.

When the lighting group for the ground floor turns off in the evening, my Hue lights are the first to turn off and then you see all the Z-Wave lights turn off randomly after that.
A bit like you see in movies when they cut the power of a city, you see all the blocks go out after each other.

[dannybloe]

You know what would be nice? If somehow the z-wave mesh network could be superimposed on the floorplans. Or something like that. Perhaps that could give you some insight. Ah well.. just fantasizing...

[bbqkees]

You can see the mesh in the Z-Wave control panel.

[dannybloe]

You can see the mesh in the Z-Wave control panel.

Yeshh indeed.. but it has no positional information in the relativistic quantum space-time continuum. And since the positions are more or less available in the floorplans you might visualize the routes through the mesh from the controller to subnodes on the plan. But the algorithm isn't that trivial I guess if you want to make it useful.

Nevermind
