Version 2.7.0. New: support for Shelly smoke detectors — add them in Hestia, a Dashboard tile (battery, last contact), a Detail screen (state, battery, muting the sound alarm), instant notifications via ntfy (relayed by another Shelly device on your local network, since the detector can't send them directly), and automatic cutoff of one or more outlets on a real alarm. Settings: the delete button no longer shows on individual outlets within a multi-outlet block — only the whole block can be removed (removing a single outlet from it wouldn't make sense).
