temperature changed

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

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

Out pins 9 + flow

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