Equivalent to HA's automation trigger condition "for"

Third party integrations Node-RED
1

I’m looking to check if one of my PIR sensor is “off” for the last 5 minutes. In HA’s Automation, I would have something like this:

trigger:
  - entity_id: binary_sensor.shenzhen_neo_electronics_co_ltd_battery_powered_pir_sensor_v2_sensor
    for: 0:05:00
    platform: state
    to: 'off'

Is there any node that would be equivalent to HA’s Automation condition “for” ?

My first thinking was to start with an “events:state” node on my PIR sensor going to off, than follow by a “delay” node for 5 minute, then check with “trigger:state” if the PIR status was still “off”. But this is not the same at all, as during the 5 min delay the PIR could have gone on/off multiple times. What I need is to check that the status has been “off” during 5 minutes, continuously.

Sometimes you have to think a little differently with Node-RED.

There may be a node that does that function, but this is how I do it. When the sensor reports the state “off” it starts the timer. When the sensor reports “on” it outputs the “STOP” payload which will cancel the 5-minute timer.

If you want it to notify you every five minutes until it receive the stop payload, add a loop.

Interesting approach, indeed things need to be seen differently with node red !
I implemented this, works fine. Thanks !

No problem!
