openHAB version: 2.5-8
Hi all, I have a problem with an Ikea bulb that have 2 items: Brightness and Color Temperature.
When I restart openhab and sometime randomly on my group with All the Lights I can see one light is ON and that light is this blulb. Actually the light is off and if I investigate I can see the problem is the Color temperature item.
It seems Openhab read the temperature status like a brightness status.
Someone had my same problem?
Thanks for your help
Why would you put a colour temperature Item in a Group, and expect to see meaningful ON/OFF results? You already have the brightness Item(s) to do that.
You are right, I can solve removing the bulb group from the all lights group but the group that contain the 2 items show the light ON. Is not a problem, but for me is a bug and I don’t know if is by openhab side or deconz
The Item has a state that only be a %, 0-100%
A colour temperature of 0% does not really represent OFF. You can still have your light on with that condition, can’t you? What would you like to happen then?
Well, the Group can only follow the states of its members in some way. How would you like your Group to react to your member colour temperature Item when the light is on but Item is at 0% ?
The brightness Item really does mean OFF when it is 0%, why not use that? Or if you must have a Group for some reason, make another Group that only includes brightness Item(s).
Is this a display thing, are you using Group in sitemap?
Yes I use it in a map, but again, for me is not a big problem. If you say is normal, for me is ok. I have a hue color strip in the same group and it don’t have this problem, that’s why I though it was a bug.
Sitemap fragment that acts like a group without false ON
Text item=yourBrightnessItem "your group label" {
Slider item=yourBrightnessItem
Slider itemyourColorItem
}
But that’s all in one Item isn’t it? Your difficulty is having two Items to represent one light, where one ofthe Items carries no useful on-off meaning.
