sensor activated

This block is part of the globals group and was last modified in core v15.0.0.

sensor activated object v15.0.0

Starts the flow when a sensor turns ON: motion detected, a door opened, water found, smoke detected.

Start-of-flow trigger. Fires when any sensor capability (occupancy, contact, water_leak, smoke, gas, vibration) transitions from false to true on an adopted device. Fires on the TRANSITION only : a motion sensor that keeps re-reporting occupancy:true fires once, when motion starts. Leave the device pin empty to fire for every sensor in the house; set sensor_type to narrow to one kind.

trigger

sensor activated starts the flow when a sensor turns ON, and the two value blocks are what narrow it: sensor type keeps it to leak detectors, room keeps it to the basement. Both are optional, and leaving them empty makes this one block the whole-house version. It fires on the TRANSITION, so a sensor sitting in a puddle and re-reporting fires the flow once, and the flow shuts the valve with switch off.
