Homekit addon - faultStatus

Hi there, what type of reaction should i see in homeapp after submitting faultStatus ON ?

i have an idea to put mapped availability status for zigbee sensors from zigbee2mqtt to help find disconnected zigbeedevices… but i don’t see any warning in home app (like it is with Low battery visualiation)

indeed, i just checked in my setup, there is no visualization for fault status in home app.
there are similar reports in internet (a little bit all but apple homekit is not something that changes often)

any ideas how to warn home app user about sensor disconnected from zigbenetwork ? low battery is already used.
