@wmarcolin I smell an X-Y problem, but I'll go on...

I don't know what "bidirectionally" means in this context. Do you mean "two dimensional?" Bidirectional refers to movement, for example, forwards and backwards, or up and down, which is a different thing.

A couple of minor comments to @Elcid 's response:

${{[["Window 1","Status On"],["Window 2","Status On"],["Window 3","Status Off"],["Window 4","Status On"]]}}

Note that this is substitution syntax, not expression syntax when defining a variable. Adjust accordingly.

each val in testarray : if val[1] === "Status On" then val[0] endif

There is no === operator in the expression language, it's just ==

(each val in testarray : if val[0] === "Window 1" then val[1] endif)[0]

This is better written as first ... of ..., since you only want the one element (which by implication here the key "Window 1" must be unique in the array), and there's no need to keep searching through the array once you've found it (wastes CPU cycles).

But about that uniqueness for "Window 1"... this is the real meat of my response:

If the first element of each subarray (row) is unique, then using a two-dimensional array is inefficient (i.e. doable, but not the best choice). Where unique values are present, an object containing key/value pairs gives immediate random access to any "element", without iteration:

devices = {
    "lamp1": "on",
    "lamp2": "off",
    "lamp3": "on"
}

In this example, we can quickly determine the status of any lamp without iteration: devices.lamp2 will give us off.

This can be further broken down with additional data: each value in the key/value pairs of the object can be any data type, so they can be an array or object themselves:

devices = {
    "lamp1": {
        "status": "on",
        "room": 0
    }
    "lamp2": { "status": "off", "room": 0 }
    "lamp3": { "status": "on", "room": 2 }
}

We can again quickly get to the state of lamp2 using devices.lamp2.status (result off again). Using devices.lamp3.room tells us that lamp3 is in room 2. Note that in the example code above, I have shown lamp1 with a typical (JSON-style) fully indented with line breaks for readability, but lamp2 and lamp3 are in a more compact form. Whitespace (including newlines) are not significant to the syntax. Use them for readability if you wish, or leave them out for compactness if that's acceptable.

When you must search within the values, you can still use iteration. Find the devices in room 0:

    each dev,id in devices: dev.room==0 ? id : null

By using each dev,id, the iterator will provide both the value and the key for each pair in the object. That is, on the first iteration, dev will contain our subobject (itself with keys status and room) for lamp1, and id will contain lamp1; on the second iteration, the subobject for lamp2 is given in dev, and id is lamp2, and so on. The result of the iteration in this case is an array of IDs of objects in room 0: ["lamp1","lamp2"]; you could also modify the iteration to return the data objects (using dev), if that was more efficient for your later use of this expression's result.

Find the first device that is "off":

    first dev,id of devices: dev.status=="off" ? id : null

Adding new devices after the initialization is also easy:

    devices.lamp4 = { "status": "on", "room": 2 }

But this is all data storage theory, and details of an implementation for a problem that apparently hasn't been stated. We need to know what you are really trying to do, if you are asking for help getting it done. As I said, where we stand right now, this seems very X-Y-ish. The post title is also poor quality, and the head post itself breaks a couple of the posting guidelines.

Hi Patrick!

%(#ff0000)[Again a Master Class on how to do the right things.]

My use case is that I want to associate each device in my installation with an identification of which group it belongs to (door, window, security, light...).

The group I will have to make the manual list (I think), so the first step of var1, I understand is the list I have to assemble, and whenever I have a new device, I update this list manually.

Just a note master, at the beginning of your example, I had to put the comma at each element of the array

I reproduced your examples to test, and I just can't find the error in the example of the first (var4).

Now comes the use, to see device names and which group they are in, or even to search the groups. My next step, is to manage when a device has the true state of its sensor, to take actions such as triggering an action/alarm/siren/message according to the group the device is part of.

If you can see, I am looking to work around not using (yet) a database, which we have had in other trackers to empower the information from the devices.

Now exploring the Master, sorry

In your last example, you explain how to add one more row to the array, one more element, perfect. Now, is it possible to add another column to the existing array? For example, with the array I created, add a column that already stores the device name? A loop that looks at the devid and then looks at the device name attribute?

I was forgetting, how do I change the contents of the array, is it possible with Set Variable? I want to change for example the group from DevWindow to DevDoor for one element.

Thanks.

[toggledbits]

@wmarcolin Well, I'm almost ready to release my first version of dynamic groups... still hashing out a few details. If you urgently need to do all this work, it's certainly a good opportunity to break your forehead on some sticky problems (I'm always in favor of experimentation and pushing limits).

First, having var1 be an expression that does an assignment to devices isn't necessary. Just call your variable devices and put in the rest of the expression after the = in your screen shot and be done with it. You can also set up your devices structure more simply. I'm not sure what the extra dev001 and dev002 identifiers are doing for you, but you can (and probably should) just use the entity canonical IDs directly. It will make everything much simpler. Here's is the expression for the devices variable:

{
    "hubitat>15": { group: "DevWindow" },
    "vera>device_1866": { group: "DevDoor" },
    ...etc...
}

Also, if group is the only data you are keeping, there is no value to creating a subobject to keep it, just make the group name be the value of the device's key/ID. But I'll continue with the structure you're trying to use...

Anyway, by simplifying the structure of devices, here's what it looks like and how it changes your first three expressions:

Looking at var2, we need to use quoted identifiers because a canonical ID contains a character (>) that cannot be used in an identifier, so this devices.hubitat>15.group is not valid. The quoted identifier syntax is context["complexKey"] as shown.

The var3 expression is simpler, because we're not looking through the extra layer of indirection your structure had introduced, we're looking directly as our descriptive subobjects.

The var4 expression is an error in the syntax on my part. The correct syntax is shown, but I've had to embellish a bit here (next release of Reactor for you, so it won't work until I publish and you update).

But here's the important part...

As for the rest of it, you're making it unnecessarily hard, I think, because entity.primary_value will give you the value of the primary attribute, so you don't really need to care what capability that comes from and go to the work of classifying devices in expressions to try to make that work. There's an easier way.

Based on what I see here, now that we understand you are actually trying to accomplish, what you really need to do is set those primary attributes in local_hubitat_devices.yaml, and skip all of the devices complexity you are creating here, and just use the primary_value from the entity in your sort/search expressions.

To do the overrides in local_hubitat_devices.yaml:

entities:
  # Entry shows how an entity can have a service added and its name forced
  "hubitat>76":
    # Name override
    name: "Attic Environmental Sensor"
    #
    # List of capabilities to add to this device (array)
    capabilities:
      - SomeAdditionalCapability
      - AnotherAdditionalCapability
    #
    # Assign primary attribute for this device
    primary_attribute: "temperature_sensor.value"
  "hubitat>178":
    primary_attribute: "x_hubitat_extra_attributes.batteryLastReplaced"

[wmarcolin]

@toggledbits

Hi Master!

Wow, good news that we will have in the MSR capacity, I am your test guy if you need a tester. And I'm aligned with you, I like to explore, learn, go to the limit, even with knowledge limitations, I seek to explore.

I will keep the array structure that can put more dimensions, surely I will explore.

Aligned from var4, I repeated your instruction and it really follows the syntax error, no problem for now, as I said we are learning and testing.

Master I am trying, to follow the correct path, instead of going all the way around creating the array. I edited the file local_hubitat_devices.yaml to test with these 4 devices, and I see that in the capabilities now appears the DeviceGroup, but I don't see in the attributes, or way to add the value.

# This file has local definitions/overrides for Hubitat devices.
---
entities:
  # Entry shows how an entity can have a capability added and its name forced
  "hubitat>NNN":
    # Name override
    #name: "Attic Environmental Sensor"
    #
    # List of capabilities to add to this device (array)
    #capabilities:
    #  - Tone
    #
    # Assign primary attribute for this device
    #primary_attribute: "temperature_sensor.value"
  "hubitat>15":
    capabilities:
      - DeviceGroup
    group: "Window"
  "hubitat>67":
    capabilities:
      - DeviceGroup
    group: "Window"
  "hubitat>98":
    capabilities:
      - DeviceGroup
    group: "Door"
  "hubitat>99":
    capabilities:
      - DeviceGroup
    group: "Door"

Now I have a question, can I use this same file for the Vera devices? Following the same path?

Thanks.

[toggledbits]

You can't make up data. Just because you assign the capability DeviceGroup to the device, that doesn't mean you get to assign the attributes (group) that may be associated with that capability. Hubitat would have to provide the group data from its side -- the values for that attribute still have to come from Hubitat. And that probably won't be happening, because DeviceGroup does not appear to be a valid Hubitat capability.

[wmarcolin]

@toggledbits I understand, so in this case for now is to use the array resource that we discussed before, until you publish the news.

Anyway thanks for one more class of knowledge.

[Elcid]

@toggledbits said in Multidimensional Array:

There is no === operator in the expression language, it's just ==

Not according to your doc's.

Also used in a test expression and working.

Noted used "in" rather than "of" as I thought he wanted a 2D array not a object/dictionary.

[wmarcolin]

@elcid actually, for the final search result, it was easier with object/dictionary, but it could have been done by array as well. Thanks, you also taught me how to make an array that will be useful for sure, it always is.

[toggledbits]

@elcid said in Multidimensional Array:

Not according to your doc's.

You are correct, I'm suffering from holiday brain-fade.

@wmarcolin Version 21331 just released has the first release of dynamic groups. It also includes a syntax enhancement to the expression first...in statement to allow a result expression, so it can return something other than what it finds (i.e. it can perform operations on what it finds and return that as a result). This is useful for your var4 of this post, which should be first dev,id of devices: dev.group=="DevDoor": id to give you the ID of the first matching device. But again, I think the combination of primary attribute assignment and dynamic groups is going to be the best way to solve this.

[wmarcolin]

@toggledbits Hi!

Perfect, you have totally changed the command.

first dev,id in var1 with dev.group=="DevDoor": dev.devid

I'm going to study the dynamic group, because even though I can compare object or array contents, the usage is horrible. It's very difficult to validate an array inside another one, or to make combined selections.

Well, I don't really know the language, so I'm having a hard time. Let's see if the dynamic groups can make something that should be simple easier.

I'll return tomorrow with my experiences

[wmarcolin]

@toggledbits

Hi Patrick!
I don't know if I'm doing something wrong, but I followed the following steps to use DynamicGroupController.

1. Stopped the MSR
2. Compared the reactor configuration file
3. Added the new Groups instruction, the one in the file is almost the same as the manual, and below is the one I set up.

  - id: groups
    enable: true
    implementation: DynamicGroupController
    name: Dynamic Group Controller
    config:
      groups:
        "low_battery":
          name: Low Battery Devices
          select:
            - include_capability: 
              - battery_power
          filter_expression: > 
            entity.attributes.battery_power.level < 0.35
        "tripped":
          name: Tripped Devices
          select:
            - include_capability: 
              - binary_sensor
              - motion_sensor
          filter_expression: >
            entity.attributes.binary_sensor.state == true or
            entity.attributes.motion_sensor.state == true

4. I restarted MSR + Tools Restart + Crtl+F5
5. Search in Entities and I see that they are created, but without content

6. Check if they are available for action, yes but also without content.

7. As the master instructed, let's go to the log file.

Well, I found this error, and obviously, I don't know how to solve it. What I did? I reinstalled the MSR, using only the config and storage directory, and the result is the same.

[toggledbits]

The groups would be empty if there were no tripped or low battery devices in their respective groups, so that's not all conclusive; it may be perfectly correct. The groups at least appear to be correct, for empty groups (no entities matched).

The time stamps in your log snippet are unrelated to the time stamp on the entities, so I can't really draw any conclusions from that either. If you post logs, make sure you are posting logs where the time stamps align to the problem you're reporting.

On your conditions, you can't compare an array to an empty string; that's not a valid test.

[wmarcolin]

@toggledbits

Ok let's go in parts, what I created in Group is the same thing I do in the traditional way and get the result, see the battery case.

I'm not seeing an error anymore, after a reboot of the MSR host.

But the array is still empty

Any instructions where I can look for something?

[toggledbits]

The recommended debugging for this would be to start unraveling your criteria and see what it produces. As a first step (don't do this, just read), I would remove the filter_expression and make sure that your selectors are producing the expected set of eligible devices. An easy way to do that is to simply put an "X" in front of filter_expression (i.e. to make it Xfilter_expression), which changes the name of the key and hides it from the code that's looking for it. You could also comment it out, but that would require that you comment each subordinate line as well, which is more work and can be error-prone. Restart MSR after config changes, of course, and refreshes are also recommended (don't need to be hard refreshes).

But, I found an error, and it's pretty subtle. For me, it logged one short line, so it would be easy to miss; I imagine you have it as well. But it's going to require a code change to fix, so I'll release another build later today. I'll also fix the doc issue you PM'd me about.

Also, don't forget that filtering by controller or capability is a good way to quickly remove "noise" from your Entities list.

[wmarcolin]

@toggledbits

I debugged removing filter_axpression entirely, and the variables are still empty. I'll wait for your version update and test again.

[wmarcolin]

@toggledbits well done

Low Battery Devices charging perfect!

But there is a problem for "tripped", which repeated the same setting as "low_battery".

Would I have to include any additional information in the configuration to not have this problem with null?

[toggledbits]

In your expression, you are not guarding for entities that have binary_sensor but do not have motion_sensor, and vice versa. Use the coalescing member access operator ?. in the two sub-expressions.

[wmarcolin]

@toggledbits

Perfect, solved, after putting the ?. in several places until I discovered how to use it correctly

        "tripped":
          name: Tripped Devices
          select:
            - include_capability:

          filter_expression: >
            entity.attributes?.binary_sensor?.state == true or
            entity.attributes?.motion_sensor?.state == true

Boss, this thread started because I want to associate to each device an information of which group it would belong inside my system, external information that I will have to prepare manually, we started with the array, then we went to object, until you announce this new function.

What is the way now? At this moment my progress is to have in a more simplified way the ID of the devices that will understand a condition, now how in the case of Tripped I will be able to associate to the groups, the list assembled before? I already saw that I can have a global variable with the information, that this Dynamic instruction by the manual will be able to read.

Could you put together an example please?

Thanks.

You still haven't stated why you want to do this, so in my view, we're on the Y of an X-Y problem. What you are asking seems an odd thing to do... error-prone, laborious, hard to maintain. If I understood why you think you need to do it, we might arrive at a better solution that works from existing functionality, or a clear requirement for a new feature. When I asked before for this clarification (and repair of the topic title), you replied with a restatement of your implementation question, not an explanation of the problem you are trying to solve (i.e. why you want to do the implementation you are asking about), just as you've again done now.

If I ask you how to ventilate an enclosed space that has small windows and a doorway that is usually left open, given no other information, what might you suggest?

Would you answer differently if I also told you in advance that the space will be a new module for the International Space Station?

[wmarcolin]

@toggledbits

Ok, I will try to explain what I want to do.

When using Vera, I in the Dashboard > My Modes panel determined which devices could trigger the house alarm in a given mode. With the change to Hubitat has no equal to Vera, and also not wanting to depend on the hub anymore, I want to have total control of the situation.

I thought about creating device groups (yes manually for now), i.e.: door group, window group, motion sensors, sensors like CO and water, and devices that should alarm and are not in the other groups.

So when I activate for example the night mode I want to trigger the alarm if the devices that are in the door group are tripped. If I enter Away mode, I want to join the devices' doors, windows, and motion. In Vacation mode, I put everything together and monitor if any device is tripped to trigger the alarm.

Another example, I can put all the liquid sensor devices in a water detector group, so when I evaluate the rule I refer to the group, and not to each device. You could say more there, just see who has leak_detector_state, but as we discussed before there is no standard, remember the discussion of the binary_sensor standard?

Another situation we could put together, the same way I put the door and window group together in Away mode, I could use it to if nothing is tripped, allow the central air in the house to work.

Trying to make a summary is, in a single table (beginning of this thread), I determine which group the device belongs to and do actions by group and not having to identify each device, we can say that it would be the equivalent in Vera as category_num and subcategory_num, and again this is from Vera, and they made mistakes by not respecting the table they created and both icon and device behavior not working, but it was interesting the grouping table (http://wiki.micasaverde.com/index.php/Luup_Device_Categories).

That is why even in this thread I thought if there was a way to add a group attribute to the devices in the MSR table, and by a set variable align this information, it did not work because you explained that if it does not come from the hub, there is no way to load the information.

Did I succeed in explaining the scenario?

Where I am at this moment:

1. I created the object as you taught:
   DeviceList = {
   "vera>device_489": {group:"Door"},
   "vera>device_432": {group:"Door"},
   "hubitat>99": {group: "Window"},
   "hubitat>15": {group: "Window"},

2. Now with Dynamic I have it easy that it is tripped;
3. I have a global variable that is loaded in each mode, DeviceAlarm, which is an object that I put who will be monitored in the activated mode, for example, set variable DeviceAlarm = ${{["Door", "Window"]}}.

What I don't know how to do now, I don't dominate the programming/language, is how to ask and/or put together Dynamic's tripped + DeviceList object + DeviceAlarm + Device name.

What do I look for? Who is Tripped (Dynamic Tripped), with the parameter filter (DeviceAlarm), in the device list (Object DeviceList)? Give me the device name in one variable, and a second variable the list of Groups that are tripped. In this second answer, I pass the list of what I want to look at in DeviceAlarm, but it should only return what is tripped.

Sorry for the bother, and you are right that I am joining topics from several different threads. I'm just trying to have something that could make the operation easier, and optimize the code in my view.

Thanks.
