Dear community,
Happy New Year everybody!
I’ve been running a stable 5.0 OH system on Ubuntu, no issues. Today I updated to 5.1 and Lutron switches are going insane. Somehow OH generates commands out of thin air, flooding the system and actually turning lights on and off.
This is what I see in the log (repeating into infinity):
2026-01-02 12:49:32.697 [INFO ] [openhab.event.ItemCommandEvent ] - Item 'Laundry_Light' received command OFF (source: org.openhab.core.thing$lutron:switch:caseta:laundry:switchstatus)
2026-01-02 12:49:32.698 [INFO ] [penhab.event.ItemStatePredictedEvent] - Item 'Laundry_Light' predicted to become OFF
2026-01-02 12:49:32.700 [INFO ] [openhab.event.ItemStateUpdatedEvent ] - Item 'Laundry_Light' updated to OFF
2026-01-02 12:49:32.748 [INFO ] [openhab.event.ItemCommandEvent ] - Item 'Laundry_Light' received command OFF (source: org.openhab.core.thing$lutron:switch:caseta:laundry:switchstatus)
If I go and turn the switch on manually, it turns back off!
There is not a single line in the rules that would use or modify this switch.
The switch is defined like this:
// luton.things
Bridge lutron:ipbridge:caseta "Lutron IP Access Point" @ "Equipment" [ ipAddress=IPADDRESSOFLUTRON] {
Thing switch laundry "Laundry" @ "Basement" [ integrationId=9 ]
}
// lutron.items
Switch Laundry_Light "Laundry Light" (gBasement_Lights) ["Lighting"] {channel="lutron:switch:caseta:laundry:switchstatus"}
Update: the problem is only related to switches, other Lutron devices like dimmers, picos, and shades work fine. Debug messages from the Lutron binding are not super-informative, it just shows a flood of messages being sent:

Please help!
