Domoticz

I recently migrated from openzwave to zwave-UI, with a MQTT broker in between, this works. I can control my devices.

However, now my logging gets these error messages:
"Error: Invalid Number sValue: '%' for device idx: '%'"

I think it only shows up when I view the dashboard webpage or some other page of domoticz, but not entirely sure.

Any suggestion what this might have caused the error ? How can I find it out ?

I think I resolved it:

WIth /json.htm?type=command&param=devices_list I found a ghost device under idx 95.

I resolved it by creating a new device under the same name and replacing it with ?itself? and then magically the error stopped appearing.
