Hi, i have a Hue Light Bulb and want to send some colorinformation to it. Unfortunately it does not let me do it without a brightness value.
Dimmer light_dimmer //name and channel stuff
Color light_color //name and channel stuff
I am increasing and decreasing the brightness with
But when i am trying to send a HSBType color information to it, it wants a brightness state.
light_color.sendCommand("275,100,<brightness>") //this works perfectly
light_color.sendCommand("275.100") //does not work, as its not a HSBType anymore
I cannot use the brightness state of the light_dimmer item, because it takes to long to update. When i send the INCREASE command, it takes up to 5 seconds for the item to update to its current dimmer state. Thats to long for what i am trying to rule.
Is there a way to send a HSBType to a color item without sending a brightness valure OR without updating the current brightness?
Yes, i only want to change the color in THIS rule. I am changing the brightness with a different rule.
I am changing the brightness with .sendCommand(INCREASE) but it takes too long for the item in openhab to update to its real brightness state.
So when i am changing the brightness and afterwards i want to change the color, perhaps the old brightness is still saved in the item and so the wrong brightness gets pushed in the HSBType.
openhab brightness state is set to 40%, real lights brightness is also 40%
i am increasing the brightness (.sendCommand(INCREASE))
light brightness changes from 40% to 70% (the openhab item is not updated yet)
i am changing the color through openhab to (100, 100, +itembrightness)
openhabs sends (100, 100, 40)
item brightness updates to 70% (real brightness is now 40%)
some seconds go by
item brightness updates to 40%
i hope you see what problems i am encountering. So there is no way for me to send the brightness state in the HSBType, as its not updating fast enough. Somehow i need to ignore the brightness state when sending the HSBType
As i wanted the brightness to be 70%, after changing the color the brightness goes back to 40%
It’s the other way around; there is no way to command a HSB without the B part.
You’ve got some choices, but not many.
You could predict the B part - “did I just send an INCREASE - then I can estimate the target B”
You could set the B to what new value you want - seems to be 70%
You could send the HSB before sending an INCREASE
