FlipFlap3

[update 2018-03-03 for version 2.2]
[update 2019-01-05 for version 2.4]
[updates 2019-04 add esh-io-transport-mqtt (needed even for serial gateway) and stop debug mysensors]
[updates 2020-02-25 update for zulu openjdk implementation and other minor adjustments]

Preparing your raspberry with clean install:
Download RASPBIAN STRETCH LITE from https://www.raspberrypi.org/downloads/raspbian/
Flash to SD-Card with etcher (https://etcher.io/) or any other flash tool you like
create empty "ssh" file in root on SD-Card
Insert SD-Card into raspberry PI, connect with UTP cable to your router and power on.
Go get some coffee
Get IP address by pinging raspberrypi.local from commandprompt on your pc
Start SSH session with putty to the raspberry pi
Login as "pi" with password "raspberry"

Initial configuration:
sudo raspi-config
Change your password
Network options\Hostname Change hostname to "openhabpi" or what you want
[optional: add wifi settings]
Interfacing Options\SPI enable
Advanced options\Expand the file system
Advanced options\Memory split change the memory split for the GPU from "64" to “16”
Finish + reboot
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install screen mc vim git htop

MySensors:
git clone https://github.com/mysensors/MySensors.git --branch master
cd MySensors

[edit update 2019-01-05]
sudo nano /home/pi/MySensors/examples_linux/mysgw.cpp

Uncomment the where needed to make it look like this:

// Config file
#define MY_LINUX_CONFIG_FILE "/etc/mysensors.conf"

// How many clients should be able to connect to this gateway (default 1)
#define MY_GATEWAY_MAX_CLIENTS 10

// Serial config
// Enable this if you are using an Arduino connected to the USB
#define MY_LINUX_SERIAL_PORT "/dev/ttyUSB0"
// Enable this if you need to connect to a controller running on the same device
// You also need to define MY_LINUX_SERIAL_PORT above with the symlink name for the PTY device
#define MY_LINUX_SERIAL_IS_PTY
// Grant access to the specified system group for the serial device
#define MY_LINUX_SERIAL_GROUPNAME "tty"

Save & close mysgw.cpp

note: I have chosen channel 69 for the rf24 network. You can choose your own, but remember to use the same channel in your arduino sketches as you do here.

./configure --my-gateway=serial --my-serial-is-pty --my-rf24-channel=69 --my-transport=rf24 --my-serial-groupname=tty
make
sudo ./bin/mysgw --config-file /etc/mysensors.dat --daemon
sudo make install
sudo systemctl daemon-reload
sudo systemctl enable mysgw.service
sudo systemctl start mysgw.service

OpenHAB2:
wget -qO - 'https://bintray.com/user/downloadSubjectPublicKey?username=openhab' | sudo apt-key add -
echo 'deb http://dl.bintray.com/openhab/apt-repo2 stable main' | sudo tee /etc/apt/sources.list.d/openhab2.list
sudo apt-get update
sudo apt-get install openhab2
sudo apt-get install openhab2-addons
sudo systemctl start openhab2.service
sudo systemctl status openhab2.service
sudo systemctl daemon-reload
sudo systemctl enable openhab2.service

Time for coffee again.......

open web page select expert....

sudo usermod -a -G dialout openhab
sudo usermod -a -G tty openhab

cd /usr/share/openhab2/addons/
sudo wget http://www.oberfoell.com/openhab2/org.openhab.binding.mysensors-2.5.0-SNAPSHOT.jar
sudo chown openhab:openhab org.openhab.binding.mysensors-2.5.0-SNAPSHOT.jar
ssh -p 8101 openhab@localhost (used to fail the first time, but works now at the first attempt)
pw:habopen
feature:install openhab-transport-serial
feature:install openhab-core-io-transport-mqtt
log:set DEBUG org.openhab.binding.mysensors
log:tail

sudo reboot

Finally:
web-> paperui/things add MySensors Serial Gateway
settings:
Serial Port: /dev/ttyUSB0
Send Delay: 200
Baudrate: 115200
Skip startup connection check: true

All done. Good luck!

When all is working well, you can stop debugging mysensors this will help to reduce the log files.
//start karaf
ssh -p 8101 openhab@localhost
//enter password
habopen
// stop debugging mysensors and switch to only registring events
log:set INFO org.openhab.binding.mysensors
// close karaf
<ctrl>D

For further reducing logs you can add them to logrotate

Hey!

The MysGW Service is running with root permissions and therefore creates the device "/dev/ttyMySensorsGateway" with owner and group root.

Please test: "sudo usermod -a -G root openhab"

Do a restart to be sure the settings are used.

That shouldn't be the final solution though.

Really grateful for your reply. Tried it and it didn't fix my problem unfortenately

FlipFlap3

solved it

Inside "/home/pi/MySensors/example_linux/mysgw.cpp" or where you downloaded the "git clone https://github.com/mysensors/MySensors.git --branch master" there is this option:

// Grant access to the specified system group for the serial device
//#define MY_LINUX_SERIAL_GROUPNAME "tty"

uncomment to
// Grant access to the specified system group for the serial device
#define MY_LINUX_SERIAL_GROUPNAME "tty"

save file

stop mysgw with "sudo systemctl stop mysgw.service"
remove mysgw from auto start with "sudo systemctl disable mysgw.service"
uninstall with "sudo make uninstall"
installed again

I added openhab to the tty group using "sudo usermod -a -G tty openhab"

full reboot

and it works!

Made a reïnstall again and found that something was incomplete and that it didn't work anymore with the stable branche.

Missing in "initial config" is enabling SPI through raspi-config at the start

At installing MySensors replace:
git clone https://github.com/mysensors/MySensors.git --branch master
with:
git clone https://github.com/mysensors/MySensors.git --branch development

echo 'deb http://dl.bintray.com/openhab/apt-repo2 stable main' | sudo tee /etc/apt/sources.list.d/openhab2.list
Now needs to be:
echo 'deb https://dl.bintray.com/openhab/apt-repo2 stable main' | sudo tee /etc/apt/sources.list.d/openhab2.list

sudo wget http://www.oberfoell.com/openhab2/org.openhab.binding.mysensors-2.2.0-SNAPSHOT.jar

sudo chown openhab:openhab org.openhab.binding.mysensors-2.2.0-SNAPSHOT.jar

Somehow this next one always times-out the first time. 2nd attempt does give me a connection after a while
ssh -p 8101 openhab@localhost

@flipflap3

I still have problem with with org.openhab.binding.mysensors-2.2.0-SNAPSHOT.jar and org.openhab.binding.mysensors-2.3.0-SNAPSHOT.jar
I get always de Mysensors Serial Gateway offline with this error

I back to org.openhab.binding.mysensors-2.1.0-SNAPSHOT.jar and now it's working again. Any ideas?

Thanks

@jic Nope sry, BUT.. I am going to do a fresh install again today. Will check if I can get it to work and make updates to this howto where needed.

FlipFlap3

2.3 snapshot doesn't work. 2.2 does

Updated opening post for step by step instruction on installing openhab2.2 with mysensors 2.2 serial gateway binding. If you have any questions, just post them here.

Seem it's working know.

I am trying to follow these instructions to set up OpenHab with the MySensors Serial Gateway, but ran into a problem when installing the Java (Third command.). Here is a copy of the command and error:

pi@openhabpi:~ $ sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys EEA14886
Executing: /tmp/apt-key-gpghome.3nAEDiCNLy/gpg.1.sh --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys EEA14886

gpg: connecting dirmngr at '/tmp/apt-key-gpghome.3nAEDiCNLy/S.dirmngr' failed: No such file or directory
gpg: keyserver receive failed: No dirmngr

Please let me know if I missed something.

BTW, this is using the raspbian stretch lite version, dated 2018-03-13.

Thank you!

@FlipFlap3
Firstly well done for the brilliant instructions . I too have been attempting to use Openhab with my sensors over the last year and to be honest although I've had relative success, because of the limited amount of, up to date and accurate tutorials its been a steep slope to climb. Currently I have Openhabian installed on a Raspberry pi with a Gateway connected to the I/O pins of the Pi and a couple of temp sensors connected ( all be it with difficulty ). It's setup as an Ethernet Gateway but I did try once to setup it up as a serial gateway, unsuccessfully I might add. Out of interest if I did re- install using your setup instructions, Is a serial Gateway better or easier in any way ? it does seem like the most supported option of the 3 for most people on the forum .

@frozenyack Sorry, I can't remember seeing an error like that before.

Sorry for late response (busy with anual reporting lately).

I have tried MTTQ first myself, but I didn't get things working smoothly. 2nd attempt was with serial gateway. Even though I had some problems at first, I did manage to get it working. I had a hard time finding a good tutorial though, so I wrote down the steps I took carefully. Reason for me to put it here was to have a personal backup for my notes and if it would be helpful for anyone else that would be an awesome bonus ;-)

I didn't try ethernet gateway yet cause I am happy with the current setup.

Hi,

The mysgw seems to be creating a link to the wrong TTY.
When I connect the arduino gateway, I get the /dev/ttyUSB1 device.

Insert Code Herepi@nettemp:~/MySensors $ ls /dev/tty*
/dev/tty    /dev/tty15  /dev/tty22  /dev/tty3   /dev/tty37  /dev/tty44  /dev/tty51  /dev/tty59  /dev/tty9
/dev/tty0   /dev/tty16  /dev/tty23  /dev/tty30  /dev/tty38  /dev/tty45  /dev/tty52  /dev/tty6   /dev/ttyAMA0
/dev/tty1   /dev/tty17  /dev/tty24  /dev/tty31  /dev/tty39  /dev/tty46  /dev/tty53  /dev/tty60  /dev/ttyUSB0
/dev/tty10  /dev/tty18  /dev/tty25  /dev/tty32  /dev/tty4   /dev/tty47  /dev/tty54  /dev/tty61  /dev/ttyUSB1
/dev/tty11  /dev/tty19  /dev/tty26  /dev/tty33  /dev/tty40  /dev/tty48  /dev/tty55  /dev/tty62  /dev/ttyprintk
/dev/tty12  /dev/tty2   /dev/tty27  /dev/tty34  /dev/tty41  /dev/tty49  /dev/tty56  /dev/tty63
/dev/tty13  /dev/tty20  /dev/tty28  /dev/tty35  /dev/tty42  /dev/tty5   /dev/tty57  /dev/tty7
/dev/tty14  /dev/tty21  /dev/tty29  /dev/tty36  /dev/tty43  /dev/tty50  /dev/tty58  /dev/tty8

Then I start the mysgw and a new tty is created: "/dev/ttyMySensorsGateway", which looks nice. However, the mysgw returns lots of errors:

mysgw: Starting gateway...
mysgw: Protocol version - 2.2.0
mysgw: Serial port /dev/ttyMySensorsGateway (115200 baud) created
mysgw: MCO:BGN:INIT GW,CP=RNNGL---,VER=2.2.0
mysgw: TSF:LRT:OK
mysgw: TSM:INIT
mysgw: TSF:WUR:MS=0
mysgw: !TSM:INIT:TSP FAIL
mysgw: TSM:FAIL:CNT=1
mysgw: TSM:FAIL:DIS
mysgw: TSF:TDI:TSL
mysgw: TSM:INIT
mysgw: !TSM:INIT:TSP FAIL
mysgw: TSM:FAIL:CNT=2
mysgw: TSM:FAIL:DIS
mysgw: TSF:TDI:TSL

Then I go check what is wrong an I see the pointer wasn't created towards "/dev/ttyUSB1", but "/dev/pts/1":

pi@nettemp:~/MySensors $ ls -larth /dev/ttyMySensorsGateway 
lrwxrwxrwx 1 root root 10 Apr 26 18:27 /dev/ttyMySensorsGateway -> /dev/pts/1

Taking a look into the /dev/ttyUSB1 directly I can see it is fine, the problem is the GW software on the Raspberry PI that is pointing towards the wrong tty:

pi@nettemp:~ $ stty -F /dev/ttyUSB1 cs8 115200 ignbrk -brkint -icrnl -imaxbel -opost -onlcr -isig -icanon -iexten -echo -echoe -echok -echoctl -echoke noflsh -ixon -crtscts

0;255;3;0;9;91 MCO:BGN:STP
0;255;3;0;9;98 MCO:BGN:INIT OK,TSP=1

Any idea of how to make this work?

Where can I see the alternatives for the "
./configure --my-gateway=serial --my-serial-is-pty --my-serial-pty=/dev/ttyMySensorsGateway --my-rf24-channel=69 --my-transport=nrf24 --my-serial-groupname=tty --my-config-file=/etc/mysensors.dat" command?

Thanks,

FlipFlap3

@joaoabs

I had to re-install myself and found my how to wasn't 100% correct for OpenHAB 2.4 so I updated it.

Works with OpenHAB 2.4 and @TimO 's 2.4 jar. Kudos to him for this!

nizoo91

My god, had everything almost working and now my PaperUI disappeared on me for the 2nd time.....

I was trying to remove and reinstall MySensors but this is the second time this happens to me :/ I don't want to re-install everything again! Any ideas on how I can get the paperUI back?

I tried removing my "addons.config" from "/var/lib/openhab2/config/org/openhab"
didn't help, also opened it and it didn't have the paperui option, manually added it and still didn't work :(

I am about to give up on OpenHab lol, is there any easier controller to setup? I heard good things about Domoticz but I JUST got OH to kinda work! I was just receiving the wrong values and thought it could of been because of some errors, so decided to re-compile MySensors and install it again.. and then poooof, the whole UI isn't there anymore :face_palm: :face_palm: :face_palm: :face_palm: :face_palm: :face_palm: :face_palm: :face_palm: :face_palm: :face_palm: :face_palm: :face_palm: :face_palm: :face_palm: :face_palm: :face_palm: :face_palm: :face_palm: :face_palm:

EDIT: oh great, even more stuff disappeared, now I only have HOMEBUILDER left! :man-facepalming:

TimO

@nizoo91 Stick to addons.cfg in /etc/openhab2/conf/services and don't fiddle with the file you mentioned above.
With package=standard (look for the examples in the comments) the UIs should reappear.

@flipflap3 said in OpenHAB 2.4 MySensors Serial Gateway - How to install:

can you please add

"feature:install esh-io-transport-mqtt"

to the tutorial it is required to get it to work even in Serial :)

FlipFlap3

@nizoo91 Just found out myself as well that this was missing. Thanks!
