alarms.attach() was given something that is not a KPI panel, a grid or a data router; nothing was attached and no alarm can be raised from it.

What happened

attach() recognises three sources: a KPI panel (it listens to tile:status), a grid (it grades the declared columns per cell) and a data router (it monitors a partition slice). The value passed was none of those, so it was ignored rather than guessed at.

The fix

Pass the instance itself: the object createKPI(), createGrid() or createRouter() returned, or the instance a framework adapter exposes (ref.current.instance, el.instance, the component's instance accessor).

The smallest fix

alarms.attach(kpi);            // a KPI panel
alarms.attach(grid, { columns });
alarms.attach(router, r => r.site === 'LON', { thresholds });
