2020-04-02 18:52:00.528 [WARN ] [rthome.model.script.actions.BusEvent] - Cannot convert ‘60’ to a command type which item ‘Jaluzea1’ accepts: [OnOffType, RefreshType].
Seems clear enough.
You haven’t said the important part, but we can guess your Item Jaluzea1 is a Switch type Item.
Like it says, you can command it ON or OFF, but not command it with a number.
Perhaps you meant your Item to be a Number type Item.
You can use a Switch widget in your sitemap to control a Number type Item (or a String type etc.) providing your commands are something sensible for that type.
Okay.
What type of openHAB Item is Jaluzea1, in its definition? JaluzeaStanga (which you showed us an Item definition for) is not the same Item as Jaluzea1 (which is giving you the error message)
