I am building an alarm system using HA. I initially did my automations in HA, but decided to try out Node Red. One of the things I was doing through the HA automations was to ignore any sensor triggers for the first 120s after the alarm was activated. This is to allow time to leave the premises. This was pretty simple in HA with an automation that looks like this:
- id: ‘1615492356581’
alias: Siren On
description: ‘’
trigger:- platform: state
entity_id: binary_sensor.pir1
to: ‘on’
condition:- condition: device
type: is_on
device_id: aba29906bf1af0c6f840effc60774f59
entity_id: switch.alarm_switch
domain: switch
for:
hours: 0
minutes: 0
seconds: 120
milliseconds: 0
action:- type: turn_on
device_id: 773a1d29a20abf6c37f3032d1d9c231f
entity_id: switch.siren_switch
domain: switch
mode: single
I was able to add a condition that a siren switch would only be triggered by a sensor if the alarm had been on for longer than 120s.
I was not able to replicate this behavior in Node Red. After quite a bit of experimentation I managed to come up with something similar. After activating the alarm I start a countdown timer, convert the counter (seconds) to a Cancel message and send this to a trigger node, which then delays and discards any messages it gets from a sensor while the timer is running (ie while it gets the cancel messages). The flow looks like this:

Does anyone have a better/simpler way of replicating the HA condition in Node Red?
