Properties of a Virtual Device Group

In my Indigo 2022.1 setup I've configured for each room a virtual device containing all of the physical devices in that room. Each of my rooms has multiple devices. I'm trying to figure out if those virtual devices might expose a property telling me how many of the physical devices in that group are on. I'm looking for an elegant way to answer the question *how many devices are on in the ______* so I can potentially trigger actions based on that number.

Failing that, I wonder if *folders* might help me get at this elusive number. Maybe I could make a folder for each *room*, put all the devices into their corresponding folder, and run some kind of nested loops to iterate first through the collection of folders, then through the devices within that folder?

I now somebody has an elegant idea for this !

I'd be willing to make a folder for each room, assign devices to that folder, then perhaps use something like "len" and "filter" to get the number of "on" devices that appear in a particular folder. Is that a thing?

Folders are purely a UI convenience. There are no scripting or server methods that do what you want. You could write your own, but it would require scheduling a script to run often (every minute?) that iterated through all devices in the system and counted how many are on in each room (folder) and then saving that to a list of variables.

If you did it as a plugin, you could just do the complete scan once on startup, and then update the room counts by observing the device updates.

I do run a script along these lines every minute, to handle devices that were inadvertently left on. I would happily rewrite it with an outer loop iterating through all of the folders (which I know how to do) and an inner loop iterating through that specific folder's devices (which I don't know how to do).

My current device loop looks like this:

Code: Select all

for dev in indigo.devices.iter("indigo.dimmer, indigo.relay"):

Is there a way to code that with some kind of filter on folderId ?

Not directly via an iteration. You'd have to inside the loop compared dev.folderId to see if it matches. Filtering on folderId at the iteration level is a good feature request though, so I'm adding it to my list.

No, so you would need to do the same outer loop, then examine each device, get the folderID, then increment a variable if the device is on. The code is pretty pretty straightforward.

You definitely would need a script. Here's a script that would inspect each device in your device group and count the number that are on:

Code: Select all

group = indigo.devices[707703952] # "All Accent Lights"
on_count = 0
for device_id in group.ownerProps["deviceList"]:
    if indigo.devices[int(device_id)].onState:
        on_count += 1


At the end of the script, on_count would contain the number that are on. Of course, this being a script, it will only be accurate for that exact point in time (as Joe points out), but as your request is just to ask the question how many are on, this script will tell you.

This is a GREAT starting point. Thank you so much! Is there an alternative where, instead of:

Code: Select all

group = indigo.devices[707703952] # "All Accent Lights"

I could use a "for" loop that includes all the group devices?

That's the third line in the script.

I believe that the third line of code gives me all of the devices in the group I specify.

I'm talking about an iteration through all of the virtual devices that are themselves groups. SO that I don't have to specify ID# 12345, ID#67890, ID# 54321 etc.

pseudo-code like:

Code: Select all

For every GROUP device
    Set a counter to zero
    For every DEVICE in that GROUP
         increment a counter if thatDEVICE is on


actually, this is pretty tight already. i can code it as a callable function and pass in the IDs of the group I want inspected and the variable I want the result stored in. that's pretty tight.

Code: Select all

for device_group in indigo.devices.iter("com.perceptiveautomation.indigoplugin.devicecollection.relayGroup"):
    # do the inner loop here

That’s perfect !

Alright, guys ! That code hit the spot !

I don't know if I shared it right, but here's the control page I was trying to build that wanted that "on" count.

Nice design!
