temperature changed

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

Home automation integration

temperature changed object v15.0.0

Starts the flow when a temperature reading changes. Set above or below to fire only when it crosses a threshold.

In pins 4

device value v15.0.0
Only fire for this device. Leave empty for every device reporting temperature.
room value v15.0.0
Only fire for devices in this room. Leave empty for every room.
above number v15.0.0
Fire when the reading CROSSES above this °C. Fires once per crossing, not on every reading above it.
below number v15.0.0
Fire when the reading CROSSES below this °C. Fires once per crossing.

Out pins 9 + flow

flow v15.0.0
device object v15.0.0
The full device: id, name, room, type, capabilities, current state.
device id value v15.0.0
Stable platform id, e.g. zigbee:0x00158d0007e1a2b3.
name value v15.0.0
The device's friendly name.
room value v15.0.0
The room the device is assigned to, empty if none.
type value v15.0.0
sensor, light, switch, climate, cover, lock or button.
capability value v15.0.0
Which capability changed, e.g. occupancy, contact, power.
value value v15.0.0
The new value.
previous value v15.0.0
The value before this change, empty on the first report.
at number v15.0.0
Unix seconds the device reported.

Start-of-flow trigger on the temperature capability, in degrees Celsius. With neither threshold set it fires on EVERY changed reading, which for a sensor reporting every minute is a busy flow. With `above` or `below` set it fires on the CROSSING only : passing 25 fires once, not once per reading for the rest of the day.
