How to check presence of Beacon ?

[korniza]

Step 1. Install FHEM on your linux pc.
Follow the guide on https://debian.fhem.de/ which incudes a repo for debian like distro.

Step 2. Configure basic FHEM settings.

As it is installed on /opt/fhem, you need to edit fhem.cfg. The very basics are the following. I just comment the last line as I got errors that do not find usb devices.

Code: Select all

attr global userattr cmdIcon devStateIcon devStateStyle icon sortby webCmd widgetOverride
attr global autoload_undefined_devices 1
attr global logfile ./log/fhem-%Y-%m.log
attr global modpath .
attr global motd SecurityCheck:\
\
WEB,WEBphone,WEBtablet has no basicAuth attribute.\
telnetPort has no password/globalpassword attribute.\
\
Restart FHEM for a new check if the problem is fixed,\
or set the global attribute motd to none to supress this message.\

attr global statefile ./log/fhem.save
attr global updateInBackground 1
attr global verbose 3

define telnetPort telnet 7072 global

define WEB FHEMWEB 8083 global
attr WEB stylesheetPrefix dark

define WEBphone FHEMWEB 8084 global
attr WEBphone stylesheetPrefix smallscreen

define WEBtablet FHEMWEB 8085 global
attr WEBtablet stylesheetPrefix touchpad

# Fake FileLog entry, to access the fhem log from FHEMWEB
define Logfile FileLog ./log/fhem-%Y-%m.log fakelog

define autocreate autocreate
attr autocreate filelog ./log/%NAME-%Y.log

define eventTypes eventTypes ./log/eventTypes.txt

# Disable this to avoid looking for new USB devices on startup
#define initialUsbCheck notify global:INITIALIZED usb create

Step 3. Install to all raspberry pi's the scan software.
Fhem-ble does not require a full FHEM installation. This script has to be installed also on Master FHEM server.

Download fle-ble init script
Move it as service under /etc/init.d/fhem-ble.
Make it executable

Code: Select all

sudo chmod +x /etc/init.d/fhem-ble

Download lepresenced script
Move it to /opt/fhem/lepresenced
Make it executable

Code: Select all

sudo chmod +x /opt/fhem/lepresenced

You need also to get Net::Server::Daemonize

Code: Select all

sudo cpan -i Net::Server::Daemonize

Install YAML

Code: Select all

sudo apt-get install python-yaml

Activate fhem-ble to load on boot

Code: Select all

sudo update-rc.d fhem-ble defaults

Start fhem-ble service

Code: Select all

sudo service fhem-ble start

verify that is has started checking netstat that 5333 port is active
netstat |grep 5333
Edit lepresenced for matching personal settings

Code: Select all

sudo vi /opt/fhem/lepresenced

Edit the following part. For Slave raspberries you need to change from loopback to the ip address to the ip of your network

Code: Select all

sub parse_options() {
        my $device                                                      = "hci0";
        my $daemonize                                           = 0;
        my $listen_address                                      = "127.0.0.1";
        my $listen_port                                         = "5333";
        .
        .
        .

Restart service and you are done.


Step 4. Install collectord on master server.
Collectord connects to all fhem-ble services and looks for the devices are configured on fhem.cfg

Download collectord debpackage and install it

Code: Select all

wget http://svn.code.sf.net/p/fhem/code/trunk/fhem/contrib/PRESENCE/deb/collectord-1.6.deb
dpkg -i collectord-1.6.deb

Before the collectord can be used, it needs a config file, where all different rooms, which have a presenced detector, will be listed. This config file looks like:

Code: Select all

# room definition
    # ===============
    #
    [room-name]              # name of the room
    address=192.168.0.10     # ip-address or hostname
    port=5111                # tcp port which should be used (5111 is default)
    presence_timeout=120     # timeout in seconds for each check when devices are present
    absence_timeout=20       # timeout in seconds for each check when devices are absent

    [living room]
    address=192.168.0.11
    port=5111    
    presence_timeout=180
    absence_timeout=20    

You can find it on /etc/collectord.conf
You need to put the ip of devices you previous installed fhem-ble and as port the number 5333 (fhem-ble use this port to communicate)

Step 5. Configure fhem & include BLE beacons

Code: Select all

nano /opt/fhem/fhem.cfg

Include at the end the following template corresponding to YOUR MAC address & Domoticz setup

Code: Select all

define NUT PRESENCE lan-bluetooth ZZ:ZZ:ZZ:ZZ:ZZ:ZZ localhost:5222 30 60
attr NUT event-on-change-reading state
define NUT_p notify NUT:present "curl -s "http://[b]xx.xx.xx.xx:8080[/b]/json.htm?type=command&param=switchlight&idx=[b]YY[/b]&switchcmd=On" &"
define NUT_a notify NUT:absent "curl -s "http://[b]xx.xx.xx.xx:8080[/b]/json.htm?type=command&param=switchlight&idx=[b]YY[/b]&switchcmd=Off" &"

ZZ : Mac Address (use UPCASE letters)
XX: IP address of Domoticz
YY: IDX of a virtual switch to associate

As you see, I used virtual switches but you can use user variables.
Also if you notice we connect to port 5222. It is the port that collectord listens. If you have devices that they are not moved you can use direct port of fhem-ble on 5333.
Save and close all. Reboot all your Master/slave devices and you have a basic setup running. After you can fine tune the timeout times for presence.

Panic buttons
As I have purchased other ble trackers till find NUT that is beaming all the time it's status, I have some of them sitting in front of my desk. So I used them as triggers for domoticz. If FHEM detect them it will send to Domoticz a call. They are associate on Domoticz as Panic Buttons, so if they go ON, using some LUA scripts they trigger alarm for fire (I have stickered them around house) or sound the alarm / turn on lights on night and get cameras on record mode.

This period I try to get from FHEM the room (as FHEM knows that from collectord) that a panic button is triggered so to build complex scenarios. Another difference with presence is that panic buttons always send their status even if it not changed. The difference on fhem.cfg is ommiting the line

Code: Select all

attr NUT event-on-change-reading state

It will send to domoticz every 30 secs (the time you set on first line) the status of panic button.

I run this setup for 3 weeks and it works great. I have also added izSynth script ON Action and our home welcome family members when they come in!

Hope I helped. If something is missing please let me know

Hi korniza

Thanks for sharing the fhem steps.
I'm trying to install it and I'm getting error on the script launch and update-rc.d ommand

I have created the two scripts, /etc/init.d/fhem-ble and opt/fhem/lepresenced and made it executable.

When I try to do the

Code: Select all

update-rc.d fhem-ble default

I get the usage

Code: Select all

usage: update-rc.d [-n] [-f] <basename> remove
       update-rc.d [-n] <basename> disable|enable [S|2|3|4|5]
		-n: not really
		-f: force

The disable|enable API is not stable and might change in the future.

and when I try to execute the fhem-ble service I get

Code: Select all

Failed to start fhem-ble.service: Unit fhem-ble.service failed to load: No such file or directory.

What am I doing wrong?

Thanks

Hi jmlegise,

I have tried your script, and It works very well. Very simple to use.

I have bought Nut trackers.

Thank you so much.

[paulD]

One question : As I am not very comfortable with uservariable, is it possible to use domoticz switch ?

[jmleglise]

Hi,

Of course It's possible. You can modify the python script to change the Url of domoticz to command your switch instead of uservariable. But I advise to you to keep the uservariable to have the Signal Strength that is a very usefull data.

So, do something like this to switch your dummy switch :

script_variable_presence-switch.lua

Code: Select all

commandArray = {}
if uservariablechanged['your uservariable of your tag'] then
  if uservariables['your uservariable of your tag']=="AWAY" then
        table.insert (commandArray, { ['name of your switch presence'] ='Off' } )
  else
        table.insert (commandArray, { ['name of your switch presence'] ='On' } )
  end 
end
return commandArray

And what do you want to do with a switch as I'am sure, you don't need it !

@jmleglise

Thank you very much for your quick answer.

I would like to play an audio message with izsynth when I enter a room. I plan to use the on action of the switch.

[jmleglise]

That's it. You don't need the switch. Just write your logic based on the uservariable. And use the signal strength to determine if the tag is in your room , near the raspberry :

variable script :

Code: Select all

commandArray = {}
if uservariablechanged['your uservariable of your tag'] and uservariables['your uservariable of your tag']~="AWAY" and uservariables['your uservariable of your tag']~=nil then 
    if tonumber(uservariables['your uservariable of your tag'])<-80 then
	-- something to do, when the beacon is near the raspberry
	-- if needed, write  a test to execute this only once 

    end
end
return commandArray

Thanks for feedback on this howto.
You need the Net::Server::Daemonize.

Code: Select all

cpan -i Net::Server::Daemonize

[jmleglise]

Hi korniza,

About the Panic button, how does it work with FHEM :

- For the simple iTag (2$) that stops emitting , do you have to switch on the tag each time with a push to the button >3sec , or just push slighly the button ? My question is : does the panic button works, when the iTag is off, (you know after the horrible bip)

- Does it work with the button of the NUT ?

[woody4165]

Hi korniza

some more feedbacks

When I installed

Code: Select all

cpan -i Net::Server::Daemonize

(with sudo, without I get a lot of errors) I get these two warnings even if the installation at the end is complete.

Code: Select all

'YAML' not installed, will not store persistent state
...
Warning: the following files are missing in your kit:
	MANIFEST.SKIP

I need sudo also in

Code: Select all

update-rc.d fhem-ble defaults

I'm trying with only one RPi, do I have to modify the /opt/fhem/lepresenced with the local ip address, leave it 0.0.0.0 or 127.0.0.1 ?

I have tried with all of three, but I don't see port 5333 in netstat after starting

Code: Select all

sudo service fhem-ble start

.

Thanks

I missed a few steps as I build it weeks ago..

Code: Select all

apt-get install python-yaml

or if you prefer

Code: Select all

cpan -i YAML

@jmleglise

Thank you very much. It's all right, I got what I need.

Your script works like a charm. You did a good job !

[micbou]

It seems like something weird had happened to my RPi3 and now the service stopped working. It seems to be a bluetooth problem.
I cant run hciconfig anymore. I've reinstalled Bluez. Bluetoothctl gives me an empty row where I cant input anything.

Any suggestions?

Code: Select all

pi@raspberrypi:/etc/init.d$ sudo hciconfig hci0 up
Can't get device info: No such device

[woody4165]

I see that with my last

Code: Select all

sudo apt-get update

it was updated some BT stuff.
Have you updated and after it's not working?
Or try to do the update...

[micbou]

I dont think I did.. i do have an idea that I have double installations running now

[micbou]

I check the log and found

Code: Select all

2016-05-28 13:19:57,108 - root - DEBUG - Tag Tag_Vanessa Detected d3:28:dc:59:b5:3e - RSSI (-88,) - DATA unknown (62,)

[jmleglise]

Hi,

It becomes difficult to follow who does what, on this thread, between FHEM and my system...

@micbou : what have you done ? did you try anything with FHEM ?

There is something not normal on your log of my system. It's not chronological. This is impossible !

2016-05-28 13:19:57,108 it's working ...
2016-05-28 13:19:59,108 it's working
2016-05-28 13:17:05,287 Doesn't work , but 2 min before ! impossible !

To help you, give us more informations. For example, there is a series of test on the wiki. I advise you to follow them and post here the result : https://www.domoticz.com/wiki/Presence_ ... _Beacon%29

like the sequence of :

Code: Select all

whereis hcitool
ps -ef | grep python
ps -ef | grep perl
sudo apt-cache policy bluez
lsusb 
hciconfig

[jmleglise]

And it's weird, I saw you have an /etc/bluetooth directory ... not with my howto !
