Issue with Philips Hue rules

Hello,

I seem to be having an intermittent issue with my rules governing the state of hue lights.

My intent is to have a dimmer item that when it’s state is changed will, through rules, force its state on the hue lights. I believed I had achieved this but ~9 out of every 10 times I restart openhab I get this error:

2017-11-06 20:56:14.578 [ERROR] [.script.engine.ScriptExecutionThread] - Rule 'All Lighting': An error occurred during the script execution: Could not invoke method: org.eclipse.smarthome.model.script.actions.BusEvent.sendCommand(org.eclipse.smarthome.core.items.Item,java.lang.String) on instance: null

If this happened every time, I would be more confident this was an error in my rules file. However since it does work on occasion I’m almost leaning toward a hardware issue or maybe something went wrong with my java install? I’m completely at a loss here.

here is my .items file as it pertains to this issue:

Dimmer House_Lights "House Lighting" (Lights)

Dimmer Hue_1 "Downstairs Hallway 1" (GAF_Lights)

It is almost certainly just a timing issue caused by your rule being triggered when the Item is updated during OH startup before all your Items have been loaded and are available.

First, try changing your rule to trigger on received command.

Second, this is a really inefficient (for you the programmer) and hard to manage way to implement this.

If you define GAF_Lights as:

Group:Dimmer:MAX GAF_Lights

Then you can put GAF_Lights on your sitemap or where every you use House_Lights using

Slider item=GAF_Lights

And you don’t need any rule at all.

At a minimum, you can replace the body of your existing rule with:

then
    GAF_Lights.sendCommand(House_Lights.state)
end

Thank you very much. as you can clearly tell i am not a programmer by trade and until now neither by hobby. Unsurprisingly this worked. I used your primary suggestion of controlling the group as a dimmer item in the sitemap. I have no issues as far as performance of the actual bulbs are concerned. However I seem to be getting a plethora of errors that all read:

2017-11-07 20:56:56.959 [ERROR] [rthome.core.library.items.DimmerItem] - Tried to set invalid state 1.00000000 on item GAF_Lights of type DimmerItem, ignoring it

My group in the items file now reads:

Group:Dimmer:MAX GAF_Lights "All Lights" (Lights)

And my sitemap now reads:

	Slider item=GAF_Lights

I have also removed my “All lighting” rule to avoid any conflict.

Any idea whats going on here?

For some reason, the Slider is returning a floating point number rather than an integer between 0 and 100. A Dimmer Item can only accept integers between 0 and 100. Slider isn’t supposed to do that so I’m not sure why this is happening.
