Trouble with group dimmers and channels

Setup, Configuration and Use Items & Sitemaps
1

I have just set up OH2 and have been working on adding some of my Hue lights. I added the Hue binding via the PaperUI interface and it detected all my lights.

Now I’m trying to create a group to control the dimming on two lights. My items look as follows:

Group:Dimmer Hue_Living_Dimmer
Dimmer Hue_Living_1_Dimmer (Hue_Living_Dimmer) { channel="hue:0100:001788105024:11:brightness" }
Dimmer Hue_Living_2_Dimmer (Hue_Living_Dimmer) { channel="hue:0100:001788105024:12:brightness" }

And my sitemap includes the following:

Frame label="Lights" {
    Slider item=Hue_Living_Dimmer
    Slider item=Hue_Living_1_Dimmer
    Slider item=Hue_Living_2_Dimmer
}

Each of the individual sliders works fine, but when I attempt to change the group slider, it does not work, and I get the following error in my logs:

2016-10-30 05:47:58.911 [WARN ] [ome.core.thing.internal.ThingManager] - Cannot delegate command '89' for item 'Hue_Living_Dimmer' to handler for channel 'hue:0100:001788105024:11', because no thing with the UID 'hue:0100:001788105024' could be found.

Any idea what I’m doing wrong? I’m seeing a lot of references for doing this sort of thing in OH1, but with OH2 and channel routing it seems… different.

This should work. Out of curiosity, does the group work with virtual dimmers? That would tell us if the problem is with the cute it the Hue binding.

Sorry, I’m pretty new to this. By “virtual dimmer” do you men setting up a device with rules attached like at Trying to control multiple dimmers with one slider?

A virtual Item is just one that didn’t have any binding. Without a rule a virtual Item didn’t actually do anything. But in this case we don’t need a rule because all we need to see is that when you move the slider for the Group you no longer get errors in the log. If you do get errors the problem is coming from the core of OH. If you don’t the problem is in the Hue binding.
