Ultimate Wifi and Bluetooth Presence Detection

[siebke]

I was using the correct syntax indeed “sudo ./iphone_roger.sh” so that’s not likely the problem.

Running the sudo/bin/bash command doesn’t seem to give any output…..?

Code: Select all

root@raspberrypi:/home/pi/domoticz/scripts# sudo /bin/bash
root@raspberrypi:/home/pi/domoticz/scripts#

I also added de Domoticz port number and this seems to change the output but sill it doesn’t work like it should.

Code: Select all

root@raspberrypi:/home/pi/domoticz/scripts# sudo ./iphone_roger.sh
./iphone_roger.sh: 1: ./iphone_roger.sh: #!/bin/bash: not found

Your sh script seems to be in the wrong format. Something like MS-DOS vs Unix encoding. Did you create the file in Windows and move it to your PI?

[siebke]

Thanks!! @bizziebis

That was indeed the problem. Seems that wen't something wrong while saving the file in Unix Encoding with Notepad++.

Got the script working but it is a bit over eager to change the status as it never gets to the 2nd attempt part of the script and just jumps to device offline, bearing in mind that this appears to pole every couple of seconds it could do with a better "cool off" period before it changes status.

Would it work with ping only?
Installing fping on a synology DS213+ is a pain... I build it from sources and fping doesn't work.

You better check FHEM for any device presence. I have described that on viewtopic.php?f=28&t=10640&p=87396#p87194 for bluetooth beacons but it can also detect from a snmp enabled wireless AP, if a MAC address is active and report state back to domoticz!

The howto guide is here:

This is a wonderful concept! Thanks for putting the script together. It gave me some little headache so I fixed it. Added a sleep statement; a resolution of 1 minute is good enough for my purpose. I've added the port number. And the quotes in the curl statements gave me errors (Raspbian)

I have the script running with Supervisor to guard its status.

Code: Select all

Need a bit of assistance with this script. Something wrong with cooling off period as it keeps changes the virtual switch on/off every minute.

[kinghuzi]

Would anyone please assist with above. Really am desperate to get this to work and wife is loosing patience with home automation project :/

[sach]

Thanks for the script. I had it running for a day but found that it was causing major battery drain on my device.

[Stewie3112]

Works fine for me, with a CSR 4.0 USB dongle plugged on my synology.
I'm able to detect my iPhone via Wifi or Bluetooth.
But I would like to go further and try to detect my beacons (chipolos), but I'm not able to find their ble mac address.
Any idea guys ?
Thx

I managed too to get the script working on my sinology, but i'm quite noob in scripting and really don't know how to automate the script without having to manually launch it... Can someone help?

[clearminds]

I have a php version of this which writes to a MySQL database and is "multi node", as in I have Raspberry Pi's around the house with Bluetooth dongles on them and they each report to the database if they can see the target device, this was my approach for extending the range of the presence detection.

I'll be making the code for the multi-node setup available shortly.

Hello Ben,

A while since you wrote this - but any progress on your multi system?

Best Regards
Daniel

Probably a stupid question but i'll ask anyway. I creatd the script and the script detects my iPhone. But in domoticz nothing happens. My idx (65) is not respondig. Any tips?

Found it. I had to set the port number for my domoticz server.

Does anyone kwow how to edit the script to detect a second device?

Hi balk, thanks for the enhancement. I installed the script and added it to crontab which start it every 10 min. Now lets see how it works.

Just create a second script for the second device.

[mlamie]

Hmm adding the script to crontab isn't a good idea... Eventually the memory increase leads to a crash of domoticz.

Screen could be an option, but is there a better way?

[pvm]

The script runs in a loop right? When starting the script every 10 minutes it will run 6times in parallel after an hour.
You should also see this behavior in the log of the switch

[mlamie]

It is not shown in domoticz since it is a external script. The actual script performs a fping/bt check every minute. I expect it only needs to be started once. Does anyone has a tip how to get it started automatically 'just once' also after a reboot of the RPi?

[possible]

Hi,

I am trying to use the script, but ive got the following errors:

Code: Select all

./android.sh: line 46: l2ping: command not found

I really dont know what cant be found??

[hannibal2206]

I removed the ´while .. do´ statement in the script so it only runs once; and call that script via a crontab entry every 1 minute.

Seems to work fine
