Device information in string or array

[wmarcolin]

Hi,

I need help to create a search within MSR that shows me the name of all sensors in a certain status.

User case: Based on the information from category_num and subcategory_num, return in a string or array the name of all devices that meet the Tripped = 1 status.

Example: generate a warning message of all the windows that are open before triggering the alarm.

Which function should I use in MSR? What would this search look like?

Thanks.

Currently there is no function or "global" value that will give you all entities. I've talked with other users about this, so it's a planned feature, it just hasn't materialized yet, and since it's core, it's probably a 1.1 thing and not for 1.0.

But, you can take a list of known entities that you specify and rip through them to see which matches a particular test (or tests). This has been covered here: https://smarthome.community/post/7041

Replying to a PM so it may sound off topic.
This is an example of how I would do it in lua:

for k, v in pairs(luup.devices) do
   if v.device_num_parent == 1 then
     if v.category_num == 4 then
       atr = luup.variable_get("urn:micasaverde-com:serviceId:SecuritySensor1", "ArmedTripped", k)
       tr = luup.variable_get("urn:micasaverde-com:serviceId:SecuritySensor1", "Tripped", k)
       if atr == "1" then natr = natr + 1 end
       if tr == "1" then ntr = ntr + 1 end
     end
     fail = luup.variable_get("urn:micasaverde-com:serviceId:HaDevice1", "CommFailure", k)
     if fail == "1" then 
       nfail=nfail + 1 
     end
   end
 end
 return ntr,natr,nfail
end

You can see in this example that I am counting specifically devices from a bridge which is device id 1 (I think it was a vera) and am counting devices which are tripped, armed tripped and failed. It's a code that I used to run regularly to check my device status.
You can then extract the name of the device and append it to a device list.

local list = {}
for k, v in pairs(luup.devices) do
     if v.category_num == 4 then
       tr = luup.variable_get("urn:micasaverde-com:serviceId:SecuritySensor1", "Tripped", k)
       if tr == "1" then table.insert(list,v.name) end
     end
end
return list

@rafale77 thanks, it worked inside Vera, but as I am leaving the platform, and as many of you have already said, my VeraPlus Hub will be just a radio very soon, I have to find a way to do it in MSR. And I don't think I'm far, I'll post a message in the sequence that may be that @toggledbits give me the missing information.

[wmarcolin]

@toggledbits first step ok, I took the example you told me to look at and that is exactly what I want to follow. I managed to reproduce the example for the battery, but now I lack the variable to test the Tripped.

I believe that attributes.Tripped == "1" is not the correct one to validate.

If you can tell me what query I have to do, I would be grateful.

[wmarcolin]

After much trying and error, I found which attribute to use, and the problem was solved. Thanks @rafale77 and @toggledbits for the tips. Now it opens a universe of new toys to put in my automation, increasing the information.

[toggledbits]

Nice job!

[wmarcolin]

One extra query, is it possible to put in an array a search that lists all the device names that meet a characteristic, for example category_num 4 and subcategory_num 1? An array that returns ["vera>device_1", "vera>device_2", "vera>device_3"].

In other words, I would like to fill in my above example, the variable OpenDoorWindList more automatically, without having to manually prepare this list.

[toggledbits]

Yes, that's what I am referring to as planned but not yet implemented in my earlier reply.

[wmarcolin]

Ah, ok, thanks!
