DynamicGroupController and attributes

@cw-kid I’ll post something on my GitHub later today, so others may benefit from this.

@cw-kid here we go: https://github.com/dbochicchio/vera/tree/master/Library

I've added a sample to RunLua as well, so this should serve well our future us when in need of it

[cw-kid]

@therealdb Great thanks

First question which folder do you store the VeraScenes.lua file on the Vera file system ?

I put it in here:

/etc/cmh-ludl

EDIT

You need to upload the file via the Vera web GUI in

Apps - Develop Apps - Luup files

area not via some other means like WinSCP.

or just use "Upload files" from Apps.

Mandatory part is to import into Lua Startup, under Apps, Develop Apps, Edit Startup Lua.

VeraScenes = require("VeraScenes")

I'll correct the readme soon.

I did that.

[cw-kid]

Its working now if I upload it via Vera GUI and not WinSCP

Thanks

[therealdb]

btw, your code seems to need some re-working to avoid warnings. try this:

function TTSTest()
    luup.log('VeraScenes.TTSTest')
    local mode = tonumber(luup.attr_get("Mode", 0))
	if (mode == 1) then
		luup.inet.wget("http://192.168.0.4:1880/scenetrigger?message=This is a Test&ip=192.168.0.16")
	end
end

That said, this won't work today, because I haven't yet connected the expressions to the action parameters

Hi

Any update on when this might happen ?

Thank you.

I have been running Lua within my Vera reactor pretty successfully. In some cases the reason was to have some conditional logic on the activity side. I found that this enabled me to keep the condition side a bit simpler and clean. I was also running lua to send Global Cache IR codes to my older Tv's. I now am trying the CG plugin that Patrick sorted out for me. The small issue with that is I need to convert all my Global Cache codes to pronto hex. I only mention so others know it does not support CG codes. There is also some lua that I use to turn off my computer. In preliminary testing the big issue I see with lua in Vera scenes is stability. I tried moving some of my lua into scenes and invoking the scenes thru MSR and everything just became real unstable with Luup restarts. I understand that this may be issues with my Vera, etc... . I also had lua in Vera reactor activities that preceded delays or other devices commands and by moving the lua into a Vera scene will that mess with the timing? Will there be a lag on the Vera side in invoking the scene while MSR continues with the reaction? The bottom line for me is I will try to make this work and eliminates much of the lua that I can. Having some legacy devices with IR contol does not help the situation I still have a lot of work to do so I can't say if everything will work out. It will be a matter of functionality and stability for me otherwise I will just stick with Vera reactor until I can't anymore. I will say that I do wish there was lua support in MSR.

Is that working then and running the Vera scene?

I can't even seem to get that far on MSR build 0.1.21062 my Vera scene isn't being run when the reaction happens.

How are you running the scene?

[Tarkus]

Yeah, scenes run but the Vera goes haywire.

[Tarkus]

[toggledbits]

If that's the case, it probably goes haywire when the scene are run from the Vera UI as well, since MSR and the Vera UI use the same mechanism to start the scene. In fact, pretty much everything MSR does with Vera is enabled by the same mechanisms that the Vera UI (and Imperihome, etc.) use. There's nothing MSR can do to mess up those scenes. It just asks that they run.

I would start at the Vera UI scenes tab for troubleshooting. Lua code on Vera can be very particular, as you know. Long delays will cause deadlocks and reloads. If you're opening sockets or making HTTP requests without appropriate timeouts and error handling, you're going to get into trouble. If you open sockets or files and are not taking steps to close them properly in all conditions, even when errors occur, you're going to exhaust limited resource handles and cause a reload or even a reboot. You really need to understand and know what you're doing, and unfortunately, there's just a lot of bad Lua copy-pasta on the forums.

I opened a PR with screen shot.

[cw-kid]

Well least you can run the Vera scenes I cannot at the moment.

I see these in the MSR log:

VeraController:ERR [VeraController:performOnEntity] action request failed
VeraController:CRIT Error: Request failed: 401 Error

[Tarkus]

I understand and I will try to test keeping MSR out of the equation. Having said that the same lua in Vera reactor did not cause any issues. What i will do is take a segmented approach and not try to finish the complete MSR project at once. If I hit trouble i will try to remedy as well as I can. I am not a coder, not great at understanding code syntax. I am good at the logical part or reactor just not lua and coding in general. I have no idea whether my code is up to par or not. It was created by copying and pasting peoples samples from the forums with some modification that I picked up from online tutorials etc. All i know is is seems to work in Vera Reactor. My Vera reactor setup is quite complex and there is a lot going on. Is running a scene outside of reactor a true test absent of the other things reactor is doing concurrent to running a scene via Vera reactor or MSR? I will try with whatever skills I can muster up but when it comes down to it and speaking of Vera Reactor and my conditional logic needs if it isn't broken dont' fix it or at least dont go crazy trying to.

I think you already discovered the problem. Running the lua through scenes is probably not a good idea. Have you attempted what was suggested by @therealdb in this thread defining a library at startup and calling your lua through that? IMO this is the correct way to do it.

@cw-kid said in Running Lua Code ? And watching device properties?:

VeraController:ERR [VeraController:performOnEntity] action request failed
VeraController:CRIT Error: Request failed: 401 Error

Have you looked at the Vera log corresponding to the time to see what it's logging? Also what happens when you run it via the Vera UI?

[Tarkus]

@kfxo I did scan thru that approach. I will definitely try to implement this before proceeding with anything else. Thanks
