Improved Presence Detection / Ping Script:

[borcon]

Hello,

i have something for you.
Many people use the phyton ping script from wiki.
https://www.domoticz.com/wiki/Presence_detection
But i missed some functions. So it was time to improve it.

New Functions:
- Sync Status
Old script does only set the device status. If the switch was directly changed in domoticz, the script doesn't get the informations back. If device is switched off in domoticz, then the script will it switch back to on.
You can control if the script should directly switch back to on or wait for x rounds or disable sync.
Control flags inside the script: syncstate and waitcount

- Support for dimmers
Old script set the dimmer level/status always back to on or off

- Ignore the on/off action in device
You have to start the script with a further parameter (NoOnOffEvent).
%Host %Switchid %Interval %Cooldownperiod %NoOnOffEvent
1 = NoOnOffEvent, 0 = Default
Important: Lua eventsystem does always get a device change

- New Action Variable
In somecases you want to switch a device without the eventsystem (lua/blocky/...).
If the script will change a device status then first a variable will be updated/created and set to 1.
You can use this variable in lua/blocky/... . If variable = 1 then "do nothing".
But you have to set the variable back to 0.
You can enable/disable the variable inside the script- ping_domo_variable = True
Variablename: Ping_IPADDRESS

- Installation
Open crontab with "crontab -e" in ssh and add your lines with your needed ips

If I test your script in my environment, I get this:

Code: Select all

Traceback (most recent call last):
  File "check_device_online.py", line 80, in <module>
    open(pidfile, 'w').close()
IOError: [Errno 13] Permission denied: '/run/check_device_online.py_192.168.2.7.pid'

I don't understand how to solve this, could you help?

[blauwebuis]

@klaasnicolaas: I suspect you uploaded a new script over the old file? That has changed the permissions of that file (the owner), and now Domoticz is not allowed to open it anymore.

You can try to change the permission settings of the file. Right-mouse button on it from linux. Of use the terminal with the chmod or chown commands (google them, there are tutorials).

You can also try to run the script with the sudo command and see if it runs then. Sudo forces a file to be executed as if it was owned by the root user, who is allowed to do anything.

[blauwebuis]

@borcon or others: could this script become a python plugin perhaps?

Only problem is that I can not find this file: check_device_online.py_192.168.2.7.pid on the pi
And the file: check_device_online.py has permission: 755

This may be a bit off-topic, but definitely related.
Until now I have used a simple ping to detect if someone is present at home, so I can switch on the right level of lighting. Both my wife and I have our own smartphone with an IP address that is consistent.
But now that I have a VPN tunnel set up, we stay linked to our home network for security reasons. We keep the VPN tunnel linked.
This means that the phone will respond to a ping, even when we're both far away....

So I am looking for a different way.
Have looked at the "nut", but it costs more than I expected, and definitely more than a simple "trial" is worth.
It would be nice to have a bluetooth app running on the Android phones, to reply to a BT app in the Pi, same as with the nut.
But I cannot find anything like that.
Any ideas?

[jvdz]

You don't need any BT app on the phone, just a BT dongle in the raspberry any you can check the presence with checking the presense of the phones BT mac.
Using it this way for quite a while now and is much more stable than IP ping.

Jos, where did you get that dongle? Do you have a link?

Hang on, I have an R-Pi-3, that should have BT in it! Now only to find a way to use it? Did you use a script? How did you configure Domoticz?

[jvdz]

I don't have a Pi3 and have read that some needed to disable it but when it is active I guess you could use it.
My LUA script is based on this idea: http://www.domoticz.com/forum/viewtopic ... +bluetooth

So I have a dummy switch and am using a LUA script which runs through crontab, that checks for the Bluetooth MAC and if not found the IP as backup.
It is setup that it can handle multiple phones, per scheduled process and am using 2 separate processes to check for the presence of 4 phone (2 phones each).
I can share the scripts I have when you want but maybe we should do that in another thread as I don't want to hyjack this one?

Well, it sounds like exactly what I need! Another thread would be good, but you could also consider putting it into the Wiki so others can use it as well?
As for BT in the Pi: I haven't disabled anything, so I assume it is functional...

[vgr2]

Sounds good, will this also work with IPhone BT?

[manjh]

It would be great if this would be in the Wiki as a step-by-step instruction! This sounds like a real improvement, and (assuming an R-Pi model 3) takes no investment at all! Virtually all smartphones support Bluetooth these days.

[jvdz]

Cleaned up the script a but to make it more generic and posted it here: http://www.domoticz.com/forum/viewtopic ... 61&t=20088

@borcon

Offcourse for those who love to ping BT devices.
Your amended script can also be used to ping BT MAC addresses.
I personally use ChopperRob his first script to ping BT devices.

Below your script with just a small edit for BT ping.
Instead of using a IP you have to use the MAC address of BT device.

call the script like this in cron:
*/10 * * * * sudo python /home/pi/domoticz/scripts/python/bt_device_online.py 22:88:72:EE:26:51 13 60 90 1

Offcourse for those who love to ping BT devices.
Your amended script can also be used to ping BT MAC addresses.
I personally use ChopperRob his first script to ping BT devices.

Below your script with just a small edit for BT ping.
Instead of using a IP you have to use the MAC address of BT device.

call the script like this in cron:
*/10 * * * * sudo python /home/pi/domoticz/scripts/python/bt_device_online.py 22:88:72:EE:26:51 13 60 90 1

When you say "Instead of using a IP you have to use the MAC address of BT device", do you then mean in the cron or in the user variable "Ping_YOURIPADDRESS"?

Edit: It's the cron that needs the bluetooth address.

When you say "Instead of using a IP you have to use the MAC address of BT device"

Beware that using an IP from an equipment that got it because allowed to connect to your network (using a protected wifi) can be considered trusted. But using only the BT mac, without another check (true pairing, checking other equipment info to make spoofing more difficult...), be aware that you're using some public info (for everyone that can someday listen BT pairing tries in reach of your phone/dongle) to control your alarm system!

Did anyone test the stability of the measurements of those presence scripts?
The well know Python script does not always deliver the correct status of my iPhone.
The bash script at https://gist.github.com/kolargol has the same problems, but does a better job.
On my Raspberry i added hping3 to 'wake up' the iPhone with a UDP call over port 5353. That delivers no improvement either

Script doesn't have anything to do with your Phone.
It's all about the phone its OS and how it handles its sleep/standby for wireless chipset.
Don't have any experience with apple products but with android devices i can say with ChopperRob his python which this OP scripts is forked off is running for 2 years without issues.
