Problem configuring Shelly Pro 4PM relay

I have a problem configuring a Shelly Pro 4PM relay at the thing level

This is the things configuration file (IP address is

Thing shelly:shelly4pro:boiler "Shelly Pro 4PM Relay Boiler" @ "Washok" [deviceIp=""]

The device appears in the Shelly Manager interface but there’s no meaningfull formation.
In the OenHAB thinss list, the device is labeled CONFIG PENDING
I get this in the karaf interface

14:06:26.915 [INFO ] [del.core.internal.ModelRepositoryImpl] - Loading model 'shelly.things'
14:06:26.998 [INFO ] [hab.event.ThingStatusInfoChangedEvent] - Thing 'shelly:shelly4pro:boiler' changed from UNINITIALIZED to INITIALIZING
14:06:29.009 [INFO ] [hab.event.ThingStatusInfoChangedEvent] - Thing 'shelly:shelly4pro:boiler' changed from INITIALIZING to UNKNOWN (CONFIGURATION_PENDING): Initializing or device in sleep mode.

Any idea what I am missing ?
