HomeMatic Value of system variables is never updated

Hi There,

I wan’t to use a homematic system variable to monitor things. But the value of this variable is never updated. Even a restart of openhab won’t force an update. Only calling “Reload all from gatway” will update the value of the variable.

Is this “by design” or is there a problem on my side?

The code:

// Item
Number DutyCycle "Duty Cycle" (gInformation) { channel="homematic:GATEWAY-EXTRAS-CCU:ccu:GWE00000000:1#DutyCycle" }

// Thing
Thing GATEWAY-EXTRAS-CCU  GWE00000000  "Gateway Extras CCU"
