[APP][Pro] Virtual Devices - Virtual Devices to simulate 1 or more real devices

The Virtual Devices App has just been transfered to me by @Arie_Laxed

That means:

  • It will be updated to SDK3.
  • Sourcecode will me moved over to BitBucket where a new issue/support-ticket-system wil be started.
    I will (try to) work through the current issue list from GitHub, after SDK3 is done.
  • Sharing of Code, Icons, etc between the Advanced Virtual Devices from Device Capabilities App and the Virtual Devices App
  • Integration into Share Your Device and The Flow Exchange(r)
  • Now that the sourceode and VD app is in my control, i want to add a feature, based on the AVD’s:
    • The ability to change a custom device icon after creation.
      Any VD with a custom icon that was uploaded while creating the VD, can be altered after creation, just like with the AVDs. :slight_smile:
      Unfortuantly, this cannot be done with items picked from the default icons during device creation.
      I might change this for new VDs in the same way as with AVDs: wether you pick one from the defaults or upload a custom icon, you will be able to change it after creation.

Well this is just a start, currently i am starting of with setting up the develop environment, sourcecontrol, stuff like that. Then i’ll work on SDK3.


In Test now: Virtual Device Test App

Updated to SDK 3.
Who wants to test and let me know how it works, because i didn’t have any VD devices.

@Peter_Kawa and @fantross, do you have VD’s?


Yes, but I use only some light switches for on/off, that’s all.
And I’m in the process of creating these devices with ADC to reduce the number of apps I have.

I have some virtual thermostats and switches running. App is installed. As far as I can tell so far, everything is running well.

So you are the perfect testuser? :stuck_out_tongue:
If it breaks, you convert them?

Nah, you can always switch back to the live version, i didn’t change anything about devices or something like that. No migrations to the new version.

Do you mean AVD from DC app? Or is there another VD app?

Good to hear!

Let’s have few more people install the test and say the same (or, if i get no reponses but see a lot of test-installs, that also works :stuck_out_tongue:)!

Of course I meant AVD, sorry.

I am gonna change the topic a bit, This is a reminder message:
This is the Old Topic Post up until i, @Arie_J_Godschalk took over on 26-10-2022.

Important Note:

This app is no longer updated. It works how it works.

My last update was 15 months ago and facing reality: Homey is developing much quicker than I can keep up. With the new release of Homey Bridge and support for TypeScript, it makes sense to start from scratch and create a new Virtual Devices v2 app that follows the latest standards.

That won’t be me, though. I have different interests. Perhaps in the future…, but no, don’t wait for that.

Feel free to take the name, the ideas and even parts of the code. In fact I would like that very much.

I can advice to create several apps:

  • 1 App for pure Virtual Devices, supporting only the capabilities provided by Athom
  • 1 App for sensors, with the freedom to combine multiple (sensor-)capabilities into 1 app
  • 1 App for modes, maybe give the multi-mode a new try
  • Specific apps for specific request. E.g. Garage doors, Swimming pools, etc.

Thanks for all the compliments, questions, and help.

With kind regards,


Virtual Devices can simulate anything without using an actual interface. Well… of course within the limits that Homey provides.

Who else can confirm that the Virtual Device App is working correct with the new SDK3 test version?

How did it go Peter?

Me, the app runs without errors.

Okay, i have submitted it for review, if i get a okay from Athom and no issues reported, im gonna publish it.

Only BetterLogic left for me a.t.m. :slight_smile:

What is the difference between this app and Advanced Virtual Devices? Basically both do the exact same thing, with the latter of course, having much more customization options. But i like the purple color so much in my advanced flows :stuck_out_tongue:

Edit: Also this app uses about a third of the memory that Advanced Virtual Devices uses. Makes sense because this one is more lightweight, but you get it haha

Hey Osirion,

Well to be honest, i think there are extrem big differences between the Virtual Devices App and the Advanced Virtual Devices from the Device Capabilities App.

The Virtual Devices App

  • This app is extremly lightweight, few hundreds kB in install size and mostly runs wel below 10MB in memory size.
  • It let’s you create a Virtual Default(!) Class/Type-Of Device.
    You can create a device, need to select a class (‘other’ is not an option(!)) and from that class you can select which default Homey capabilities (fields in AVD) you want to have on this VD.
    What you now get is in accordance with it’s name: a Virtual Device.
  • You can pick/upload a custom icon for the device itself during creation.
  • Very easy to use: absolutly no customisation or settings needed after device creation.
  • Al(most all) based on default Homey flowcards.

The Advanced Virtual Devices from Device Capabilities

  • The install size is about average to large, with al it’s default icon’s compressed/zipped in it, with currently 6MB. Memorywise it runs normally between 23MB and 30MB, but depending on your Homey and when you create AVDs or use Share Your Device or The Flow Exchange(r) you can easily get up to 50 or 60 MB of memory.
    So for a default VD, the AVD and DC is a big overkill imho.
  • It let’s you create a Virtual Completly-To-Your-Wishes Device.
    • You can set the class to any type, including other, making it not visible on certain other apps and software. You can do this after creation.
    • You can add the same capabilities/fields multiple times.
      This means you can have one AVD controlling multiple real device through separate UI controls (like buttons). Take this AVD Template for example: Control 2 dimmable lights as one. It let’s you control two real dimable lights through one AVD, but the AVD actually has a totla of three buttons (not possible with VD).
      Or this more extensive Living room example. Here you have 3 neat looking custom-iconed buttons, with custom names and everything. These custom names also show up in flows, making it very readable.
      I have actually added a few thing to my Living Room AVD, like the curtains and Sonos. All Living room devices within one(!) AVD. This kind of stuff is not possible with VD.
    • AVDs can have as many fields as you would like. Except for Homey, browser, javascript, max-number-length, etc., limitations, there are now App limitations to how many fields you can have.
    • You can add fields like Camera, multiple times, so you can put all camera’s in one AVD. Much more handy then a lott of devices in on “Room”.
    • You can create your own capabilities (fields), not just pick from the default Homey types.
      All default types can be used, but you can also pick a lott of other options or just set every field-option yourself. Create a Tag or insight, give the field a Name or Icon, SHow it or Hide it, Make it pushable or not. A lot can be customised.
    • You can now even add default lists/pickers and a few default-custom lists. (And you can request to add your own custom picker/lists to the DC app).
    • You can customise the Device icon but also the Field icons (Buttons, Sensor, etc.) after the creation of the device.
    • You can pretty much reconfigure your whole AVD after creation!
    • You can Export and Import you whole AVD including it’s flows to other users.
      Share Your Device! - Advanced Virtual Devices from Device Capabilities.
      The Flow Exchange(r) - Exchange Your Flows with Others! - Flows - Homey Community Forum.
      I know people are gonna be hesitant about SYD and TFE, but it actually works pretty well already!
      See for example these posts with @fantross: AVD created and shared with fantross.

Being able to create this Control 2 dimmable lights as one AVD is Unique!
There is no other way then AVD to create one virtual device to emulate multiple devices in one.

Being able to create an (A)VD and Share Your Device including flows with another user is Unique!
Even Athom doesn’t have a method for this :stuck_out_tongue:

Being able to import a AVD from someone else and have the flows configured to your own devices is Unique!
As soon as SYD and TFE becomes more well known and people start trusting and using it, this will be a very handy tool for helping others and newcomers!
I know you should create most of your own flows to start understanding it all, but be real, why keep inventing the wheel over and over and over? Why would i need to explain to @fantross HowTo make the AVD and it’s flows, while explaining it will take me longer then creating it (if i want the images i already need to create everything first) then to just give it all to him: The AVD and Flows. And now he doesn’t need to really configure much, so less change at a mistake (since else he would need to create everything based on my print-screens and explanation).

So, i really like VD and it’s simplicity.
And i don’t think AVDs are gonne surpase it and i’m not sure it should.
VD is very easy to use, very handy for a lot of users.
But VD “only” let’s you “pick a (limited) default Homey Device”.


AVD let’s you create your own device, the way you like it, with all the fields you need and the icons you prefer!

Also, AVD was build out of the need from a user to be able to set a Text on a Device Tile in the Homey/Web App:

From that, AVD (and DC) has grown very fast into a completly Unique App, there is no other App like it.
And yes, it does many things that other Apps do in some way or another, like VD but also like Better Logic: Add fields to an AVD and put the Tag and Insights On, and you have got about hte same thing, only now your variables are grouped together and you can have Image-variables.
But i don’t know about any App being able to simulate what AVD’s can do.


Yeah, the skills i have in developing, i lack in design :grimacing:
And DC was never intended to grow like it now has/is, i didn’t put the effort in to ask for a design back then.
And for about 1,5 year there were only 150 users, so i guess that was fine.

But since AVD it’s been multipling like crazy, so i might actually need to rethink the design and ask @johan_bendz if he has any good sugestions for the images, icons and color.

I do like my own made Robot-head a bit tho :stuck_out_tongue:

Amazing rundown of the features. Thanks for taking the time! Realy helpful to see the big differences between the apps to base my choice on.

The robot head is a fun one, you should defo keep that. If only for nostalgic reasons!

Update to the latest version?
There was an API bug in a previous version.
