[APP][Pro] < group > (2.5.3 - Stable)

New to Homey and recently tried this app.
I have an issue when using Hue lights, is this a known bug?
I have 12 hue lights in my living room I would like to group together.
I am able to group them, but whenever I try to give the group an on/off or dim command, i get an “undefined” error.
The app works with two non Hue lights.

Last time I got that one I played around with the settings on these and got it working.

Is there a way to add more devices to an existing group or do I need to create a new, extended group and replace the group in all flows?

Three dot/more-apps-group-configure app.
Then choose the group you want to configure.
Then you can edit, but only within the selected criterias.

At least I haven’t found anything “deeper” than that.

Thank you for the reply and sorry - the question didn’t mention that. I know about the options in your screenshot, but I’m missing the option to edit the criteria. That’s my problem, because I’ve chosen a very narrow criteria set and would like to expand it now.

For this you need to create it again. I am missing this too :thinking:

Hi everyone,

I’ve just released version 2.4.3 to the testing branch, it should roll out to everyone :soon:

You can use the latest version here : https://homey.app/a/com.swttt.devicegroups/test/

Latest version fixes an issue in v5 where you would have to restart the app in order for a new group to work correctly. Also removes a common error from displaying and instead logs it and updates the app the latest version of the athom api.

Thanks and please let me know if you have any issues.


Thank you for your excelent work, Jamie!


I get an unexpected character while parsing group as device through the Newtonsoft JsonConvert Deserializer. All other types of devices work, except groups.

Any suggestion why this is? Is there a property not documented in my models?
It is under: this object:
public class CapabilitiesObj
public string Value { get; set; }
public DateTime? LastUpdated { get; set; }
public string Type { get; set; }
public bool Getable { get; set; }
public bool Setable { get; set; }
public string Title { get; set; }
public string Desc { get; set; }
public string Units { get; set; }
public int Decimals { get; set; }
public int Min { get; set; }
public int Max { get; set; }
public string ChartType { get; set; }
public string Id { get; set; }

I just installed a Frient Entry Sensor and it doesn’t appear in the list of sensors that I can select when updating a group (contact alarm group). Any clue of what might be happening? Homey v4.2 and group v2.4.304.

HI, i noticed that when making a group device with temperature capability for average temperature of 2 or more temperature devices in the (new) web-app the value isn;t shown. When i click the button te value is shown.

In the mobile (android) app nothing is shown.
Is this something you can fix? Restart of the app did’t work.

Sinds de update v5 werkt het niet zo lekker meer met deze app en hue lampen.
Lampen groupen gaan niet aan omdat hij denkt dat de lamp groep al aanstaat via flows.
Als ik dan op de tegel twee keer klik dan gaat alles weer aan ook dim levels kloppen soms niet meer.
voor de update deed alles het goed.

Since the update v5, it does not work so well with this app and hue lamps.
Lamps groups do not turn on because he thinks the lamp group is already on via flows.
If I then click on the tile of the group twice, everything turns on again, also dim levels are sometimes no longer correct.
before the update everything was fine.

Did you try to just restart the app? Sometimes this resets this kind of errors

Yeah i can try tho do that.

I’m having rooms/groups of IKEA Trådfri bulbs with up to 14 bulbs in one group. After moving my bulbs from the IKEA GW to Homey directly in Homey version 5 I experience that sometimes not all lights take its command. I therefor wonder if I should set some values in advanced settings (delay and debounce) for the group to make it better. If yes, which settings work good for you?

Delay of 100ms should work.
If not, try 125ms and so on

Hi, i have 6 Philips hue GU10 White Ambiance BT lights in a groupe.
When the lights are in a group in the flow card under dim to the duration is not available.
When I select a single light without te group app this option is available.
Hope there is a fix, now the light jump instantly two another dim level.


I think that’s not possible for now.
I use the Chronograph app for transitions for any light or group of lights.

U can set the nr. of steps & transitiontime as u wish
In these example flows the light dims from 0 to 100 in 7 steps during 1 hour

Thanks for your answer
What I actually mean is for creating a smooth transition between dim levels.
This is also discussed around post 130. When my lights are for example at 80% en I dim them to 20% (movie time) they jump to 20% instantly, because I cannot set the duration in the groupe flow card, and its set standard to 0 sec with the hue lights. In the dim level flow card of the lamp by themselves this is possible, for example 4 sec the lights go from 80% to 20% smooth in 4 sec.

Hope there is a fix, otherwise the dim function in a groupe is practical unusable.

I know and understand what you mean.

As far as I know, it is a Hue only option to set the dim duration in the action card, correct me if I’m wrong.
This is why i explained the transitions trick with chronograph. Instead of a wake-up light, you can set it to dim from A to B in 20 steps during 4 seconds. Just how you would like it.

I have made a simple test but I can’t get it to work, lights do nothing.

Am I doing something wrong?
