Yes. The cause is the same as described here: https://community.openhab.org/t/mapping-of-item-values-not-correctly-shown-in-habpanel/19518
That’s because the Rest API call returns for the state call for one item or the change on the event bus only the “unmapped” status - but when getting it through the item “overview” call it returns the “mapped” status. That’s why HABpanel “jumps” between the two views.
I’m not sure if it can solved by HAPpanel only.
