Different ways of detecting presence

[Manuel Medrano]

Hi all,

I would like to see how to activate or deactivate the house alarm depending on whether someone is at home or not.

The idea is that when the last person in the house leaves, the alarm will automatically activate.

I can think of different ways to do it, but I can not carry them out.

I would like to do it with geofence, but the implementation I do with IFTTT is with http and not https, so it is not entirely safe to send username and password with the command.

I also think of the Wi-Fi at home and a Ping to mobile phones, but I do not always have wifi activated.

I would not like to have to ride anything weird, raspberry type or similar systems, unless it is strictly necessary.

At home I currently have Loxone, a Google home, a Synology DS215j and a Foscam camera.

I would like to be able to do something with these devices if possible without having to mount anything apart.

Any ideas? Do you have this implemented?

If everyone has a smart phone you could use their connection to wifi. I'd make it a twofold criteria - no phones connected and no motion detected. That way if someones battery runs out, then you aren't trapping them.

I monitored the arp cache on my wireless boxes for phone presence.

I do this by specifying 4 ip addresses that the home owners assign to their phones using static IP addresses.

If any of these 4 IP addreses respond to a ping (every 10 seconds), then it renews a presence timer which sets a global variable 'home' to true.

When the presence timer expires after 20min then 'home' gets set to false which sets the alarm, closes the garage door if it is open and lights turn off etc.

I also insert a switch in the UI which allows people to disable this function. Then everything has to be done manually.

It works well, though I would recommend mounting a WiFi access point outside so that it picks up phones as people enter the driveway.
This can then be used to open the Garage door, disable lights and turn off the alarm as a member of the family drives in the gate.

Hi Toby,

How are you performing this ping every 10"?

could you post the config?

Thanks

There is a function block for ping. You can define the IP, interval etc.

Thanks for the info,

another question came to my mind when reading "This can then be used to open the Garage door, disable lights and turn off the alarm as a member of the family drives in the gate."

Is it possible to disable the alarm without enter the passcode?
