PaperUI is an AdminUI, showing the actual states of items is just an additional feature and only for those items that are linked to channels.
Furthermore PaperUI won’t be part of the coming openHAB3.
For both reason such a bug will not be worked on.
Use any UI meant for the daily use (sitemaps via a BasicUI or any smartphone app or HABPanel ) to show the actual states of any item.
Will is also be replaced?
I plan to build a Magic Mirror and Openhab should be supplier of data and rule engine.
Until now i did not now which UI i will use.
HAPPanel, Magic Mirror 2 or a complete self developed Web UI (maybe based on Telerik kendo UI and Angular).
Until now i use a lightwight self developed UI hosted in /html folder in openhab.
I own a E3DC PV and use Modbus binding and influxdb. All diagramms are Build with Telerik kendo UI. These diagramms works better on mobile devices as Grafana.
