openhab-addons: [hue] Wrong additional channel update after sending command (API v2)

For this thing:

Thing device wiser1 [resourceId="00000000-0000-0000-0000-000000000000"]

and this item:

Dimmer DinnerTableLamps_Brightness { channel="hue:device:home:wiser1:brightness" }

when performing this command:

openhab:send DinnerTableLamps_Brightness 100

the following scenario plays out:

2023-10-05 21:32:40.330 [INFO ] [openhab.event.ItemStateChangedEvent ] - Item 'DinnerTableLamps_Brightness' changed from 0 to 100

Summary to highlight the issue:

• 2023-10-05 21:32:40.198 Item ‘DinnerTableLamps_Brightness’ changed from 0 to 100
• 2023-10-05 21:32:40.318 Item ‘DinnerTableLamps_Brightness’ changed from 100 to 0
• 2023-10-05 21:32:40.330 Item ‘DinnerTableLamps_Brightness’ changed from 0 to 100

Although it ends with the correct state, this additional update is a problem. For example, it will cause unneeded/confusing persisted values. It also causes some strange flickering when using a slider in a sitemap to control the light.

Expected Behavior

I would expect to see only the relevant update setting brightness to 100.

Current Behavior

brightness is updated to 0 after being commanded to 100, then set back to 100.

Possible Solution

I have not looked into the code yet, but might update this issue unless someone will find the issue before me. 😉

Steps to Reproduce

See description.

Context

I have this rule to trick the Wiser dimmer into turning off when the Hue app turns it off without transition time (more details here):

rule "Wiser work-around 1"
when
    Item DinnerTableLamps_Brightness changed to 0
then
    // Work-around for required transition time for LK Wiser
    // relays and dimmers.
    if (Hue_Wiser_WorkAround.state == ON)
    {
        DinnerTableLamps_Brightness.sendCommand("0.0")
    }
end

This will be triggered by the excess update, and as a result, this rule will not work:

rule "Morning wake-up family room"
when
    Time cron "0 30 6 ? * mon,tue,wed,thu,fri"
then
   if (Hue_WakeUp_FamilyRoom.state == ON && Anyone_Home.state == ON && !Ephemeris.isBankHoliday)
   {
       DinnerTableLamps_Brightness.sendCommand(100)
   }
end
