Hi Community, thank you for your tireless support.
OH3.1 on ubuntu20.04 using a combination of text file configuration and PaperUI.
I have a file based item, which I’m trying to update and read from in order to set light temperature. I’ve read over the forums, seems the right way to grab the number is via a particular command, but I’m still getting an error.
The item receives updates OK, but when I try to take the value and throw it into a variable in a rule, I get an error. In short here’s the line I’m trying to use:
var Number LT = (Colour_Temperature.state as QuantityType<number>).doubleValue
logInfo ("Study", LT)
But I get the error:
2021-06-08 23:51:09.981 [INFO ] [org.openhab.core.model.script.Study ] - Study Lamp Day Motion Detected
2021-06-08 23:51:09.982 [ERROR] [internal.handler.ScriptActionHandler] - Script execution of rule with UID 'MotionStudySpotLight-1' failed: Could not cast 95 to org.openhab.core.library.types.QuantityType; line 11, column 21, length 48 in MotionStudySpotLight
Is it because I’m using the wrong command or casting incorrectly?
item definition for light temperature:
Number Colour_Temperature "Colour Temperature [%.2d]" <light> [ "CurrentLightTemperature" ]
Rule that updates it with the temperature based on the time of day:
rule "light_colour_temp"
when
// every 10 seconds for debugging purposes
// Time cron "0/10 * * ? * * *"
// apply every two minutes when actually running - that should mean it rarely/never changes
// by more than a 1% increment
Time cron "0 0/2 * ? * * *"
// Item HueMotionsensor2_motion received update or
then

Output in the log on updating colour temperature (showing the rule works):
