Thanks Ian I can see that now its listing all my Vera scenes so that's easy enough to have your Reaction run a Vera scene and then in turn any Lua Code that scene may contain.

I'm interested to hear more about what TheRealDB mentioned regarding a RunLua action.

[Elcid]

To RunLua you would need reactor on the vera. you could then call it from MSR

Also the {variable or luaxp} works in reactor and will be working in MSR in the near future

Yep that also make sense. Is that what TheRealDB was referring too ?

I don't know what this means.

[Elcid]

{variable} - refers to expression variable.
you can set dynamic names in input fields and you can also use luaxp

This reactor page explains more https://www.toggledbits.com/static/reactor/docs/3.6/Expressions-%26-Variables/#luaxp-built-in-functions

This will probably be available in MSR to.

You can monitor the dimming level of a dimmer using an Entity Attribute condition and checking dimming.level for the dimmable entity. You can easily do a "master-slave" (or Submasters !) style of dimming mirroring in MSR.

I'm still working on the scene controller device mapping. Please remember that this is a developer preview, first time this code has run outside of my hands, and is expected to be incomplete. It's not a finished product at this point and isn't intended to be. If you're using it with that eye, you may want to wait a couple of months.

You can run scenes from MSR on the Vera using an Entity Action. Each scene has a corresponding script entity in MSR, with a script.run action available.

And of course, the XY-Problem aspect of this... if you tell us what you think you need to run in Lua, there's a chance there may actually be a way to do it without Lua, or its something reasonable to consider as a regular feature addition to MSR, Vera Reactor, or both.

[therealdb]

@cw-kid you can run lua code via http call. Just compose a call like this

http://ip-address:3480/data_request?id=lu_action&serviceId=urn:micasaverde-com:serviceId:HomeAutomationGateway1&action=RunLua&Code=YourLuaVode

Ie, if you have a function named doSomething in your startup code, accepting two values, just call this endpoint

http://ip-address:3480/data_request?id=lu_action&serviceId=urn:micasaverde-com:serviceId:HomeAutomationGateway1&action=RunLua&Code=doSomething(1, ‘abc’)

I’m using it to concatenate multiple actions in one http call, while still maintaining flexibility.

[cw-kid]

Thanks guys for the information.

Yes I admit I need to keep remembering things might not be implemented yet.

But as I have never used Reactor plugin for Vera, I have nothing to compare MSR against other than PLEG.

I don't know what is currently possible in the Reactor plugin for Vera etc which isn't helping me when looking at MSR.

I am moving my more simple PLEG actions over to MSR now and have already disabled several PLEG conditions on the Vera box.

Schedules in MSR I am still testing and struggling with a bit, so I only have two moved over to MSR currently and one isn't running at all and one ran this morning but later than I expected it to do so.

I have some pretty long LUA scrips in PLEG for some stuff, I don't think I could do it easily without using LUA code.

Are there any examples of a Master Slave dimmer setup which I can follow ?

Cheers.

[cw-kid]

@therealdb said in Running Lua Code ? And watching device properties?:

OK that's a clever idea.

So the LUA code is stored where? In a function in the Vera startup right. And then you are just calling it to run via a HTTP request from MSR.

[cw-kid]

Regarding a Master Dimmer

Think I have the Trigger (Condition) correct but don't know what to do with the Reaction ?

Do I need to create a variable some where? Or can I directly control the real lamps based on the "changes" of the virtual Master dimmer ?

[toggledbits]

This is how it will go:

That said, this won't work today, because I haven't yet connected the expressions to the action parameters (the {master_level} value in the dimming action won't work yet). That's coming, but not yet. You can, however, do exactly this in Vera Reactor to see how it works. It will work the same way in MSR.

Edit... let me explain how it works (on both Vera Reactor and MSR):

The expression keeps the current value of the master dimmer. So on my system, vera>device_105 is named "Virtual Dimmer 18". The trigger condition looks for any change in the dimming level of that dimmer. When it changes, the set reaction sets the current value (from the expression master_level) on the slave dimmer "Virtual Dimmer 20". Bob's your uncle.

[cw-kid]

@toggledbits What you just explained makes perfect sense.

However I would not have had a clue how to correctly construct that expression with the correct syntax.

I think I have mine setup correctly now.

I understand it wont actually work yet though.

[toggledbits]

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

Right, so I think this is a big issue in your case. My intent with this developer preview was to have experienced Reactor users help me test MSR. You're in the tough spot of coming from PLEG, with no prior Reactor experience, so not only do you not know the current product, but you also don't know if what you're looking at in the new product is right or wrong, same or different. That makes it palpably frustrating for you, and frankly for me as well, because you are not at the level I set for this test. I suspect you're also a bit irritated at having to do this at all, since Richard seems to have abandoned his product years ago (as evidenced by his near-total absence in the forums, the maturity of his product notwithstanding), and the prospect that no PLEG for eZLO seems to be in the works that I've heard.

None of that matters, at least to me, and I appreciate the effort you're putting in, and you're finding bugs and helping, so all is cool in my book, but for the fact that I feel like you're sometimes losing your perspective and treating this as if it's finished and shipped. This is a developer preview, and again, it's known to be incomplete, and its intended audience was existing Reactor users. Those users would know how to build the expression. If you're going to continue to participate, and I hope that you do, please keep this in mind. Making contact with the product this early, you are not only positioning yourself to be a master of it in future, but you're in a position to shape its future, and you have my attention.

You might take a read of the docs for Vera Reactor, to get a better lay of the land, including expressions. Things are different between the two systems, for sure, but the strong flavor is nonetheless there. You can also experiment with Vera Reactor on your Vera directly, and this may actually be very useful in helping identify other differences or gaps that should be at least documented if not closed. Either way, as the more mature product and very stable, it should help remove some of the questions and the trips in your learning curve caused by my errors in the new product. That said, I think I've shown that I will work as quickly as possible to get things shored up so that you can be productive on MSR.

@cw-kid yes, but if you define a library and register it at startup, you could do that too. I’m currently using this approach, and I like it because it’s inside a file and not a textbox.

[cw-kid]

All fair comments and observations Patrick. I certainly don't want to cause frustration to anyone.

In PLEG there was no need to of even written an expression just to monitor the value of a devices Dimming level for example. I'd just create a device property.

PLEG device properties are similar to how you build triggers in MSR, in the respect that you just select things from drop down lists. So monitoring a devices Dimming level in PLEG is trivial to setup.

Conditions in PLEG are not so trivial however and are more like writing expressions.

If MSR could build device properties or watch variables as PLEG does I think you'd be making it super easy for any user to pick up and run with MSR.

[Elcid]

In vera reactor to watch a device state you just set a variable and there is a button to pick what you want to get/watch, this creates the expression for you. The button exists in MSR, but as Patrick says expressions are not fully implemented yet. When it is you will see how simple it is. Install Vera reactor just to have a play.

[cw-kid]

OK sounds good.

I'm really not getting what you're on about here. In your example earlier in the reply, monitoring the dimming level of a device is just this simple in MSR or Vera Reactor:

You literally select the device and the attribute and you're done, with all the different operators to choose from as well. There's no need for an expression at all. The only reason we have an expression for your ealier example/request is that we need to copy the attribute value from one device to another. But if we were just going to turn on another light in response to a light turning on, no expression needed.

Can you give me some easy to follow instructions on how to do this please?

I like the idea of having my lua code in different files stored on the Vera hub and then being able to have that Lua code run by sending a http request from my MSR rule etc.

I would like to reduce the number of Vera scenes I currently have also.

[therealdb]

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

[therealdb]

@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
