    ( 03 | openHAB Stable Install or upgrade to the latest stable release of openHAB 2 )

i see a lot of warnings in the openhab.log all like:
[WARN ] [rest.core.item.EnrichedItemDTOMapper] - Failed transforming the state ‘NULL’ on item ‘Welcome_Stef_AtHome’ with pattern ‘MAP(’: Couldn’t transform value because transformation service of type ‘MAP’ is not available.

in my item definition for the item “Welcome_Stef_AtHome”:

Switch Welcome_Stef_AtHome “Stef [MAP(]” (gPresens) file exist unter /etc/openhab2/transform

and it looks like:

ON=at Home

So what does the WARN mean? and what to change to stop the warning.

Thanks for your hints ans tips and excuse my english. and excuse if i placed this message under a wrong category. I try my best to fill in all informations.


Hi Stef,

Restart OH once or twice - letting it start up all the way. This should fix the issue after your update. I keep getting the same warnings with most updates as well, and several complete restarts usually solve them.

All the best.

Also try clearing the cache.

Hi Hans, hi Bruce,
Thanks for fast support:

After restart the openhab2 service all the warnings are gone!

so everything is fine … topic can be closed with “solved message”

I had to restart once. Some have had to do it up to 3 times.

I restart the service only one time.

Sorry forgotten: i didn’t clean the cache - i only restart the service a s mentioned before one time and the warninigs were gone.
