Just define a StateChannel with a Level (INFO / WARN / FAULT), like this code:

github.com/OpenEMS/openems

io.openems.edge.battery.fenecon.home/src/io/openems/edge/battery/fenecon/home/BatteryFeneconHome.java

develop


      
          		RACK_LEVEL_2_CELL_UNDER_VOLTAGE(Doc.of(Level.WARNING) //
          				.accessMode(AccessMode.READ_ONLY) //
          				.text("Rack Cell Under Voltage Fault")), //

It will be visible in the UI, once the Channel value is set to true
