Need help with presence logic – delay before turning lights off

Flows

Goal:
I want the lights in my living room NOT to turn off if I leave the room only briefly (e.g. for 60 seconds).
They should turn off only if the room is really empty.

Setup:

  • Aqara presence sensor (mmWave)

  • Homey Pro 2023

  • Lights controlled via Shelly

What I want to achieve (logic):

  1. When no presence is detected → wait 60 seconds

  2. If there is still no presence after 60 seconds → mark the room as empty

  3. Only then allow any flow to turn the lights off

  4. If presence is detected again within those 30 seconds → do nothing

2

This can be boiled down to one flow:

WHEN the “living room” zone has been inactive for 1 minute THEN turn off the light

Can you please send me a photo/screenshot of where exactly this is set in Flows or Logic?
I'm a new user of Homey Pro - I've already added the devices and they work properly, but setting up Logic is more challenging for me so far.
That's why I want to fine-tune it: when I leave the living room for the kitchen, the light turns off immediately, and I would like it to stay on for a certain amount of time.

Thanks !!! :)

Just search for “zone”:

FWIW, this obviously depends on you having set up a “living room” zone, and placed the sensor and the lights in it.

So far I have it like this. FP300 - LED OFF - GOVEE LED OFF

So should I go where you sent me now? ….

(I copied the time-condition from your flow. Be aware that outside this time frame the lights will stay on when the zone is inactive for more than 1 minute. I don’t think that’s what you want)

Thanks, I’m going to try everything and let you know later tonight if it responds and works properly.
Thanks everyone, if anything happens, I’ll get back to you.

You should also have a trigger possibility like when presence us iff/deactivated for … (a duration/time period) like my SwitchBot presence sensor has (if you have the latest Homey pro firmware:

So you van set an amount of seconds or minutes a certain state should last to trigger a flow.

So set a trigger of “When presence is de-activated for 60 seconds …” Then ….

Using the zone not active for …. Like other users above have mentioned is an other possibility but other sensors(door/windows cotact sensors or other IR motion sensors with longer period of time till they report a “no motion” with alarms might still jeep that zone active while nobody is in the zone anymore.on the other side : using zone (in)activity might prevent false negatives(=false “no motion/presence”).

I always combine an IR motion sensor with a seperate presence sensor in zones/rooms where its very important to make sure that any false positives ir negatives are being prevented as most as possible. (Like my living room / computer desk/ sleeping room, lavatory & bathroom. (Nothing is more annoying when the lights turn of while showering with shampoo :lotion_bottle: on your head/in your hair and almost closed eyes to prevent shampoo getting into your eyes. All this because the only motion sensor is a IR sensor without the capability to sense your presence in the shower (behind the glass or shower curtain).

I also recommend a vibration sensor (from Third Reality brand) on your gaming chair , bed/matrass and/or couch as redundancy precaution.
