openHAB binding

BastienVH

After reinstalling OpenHAB, the binding works fine, thank you!
Just a question, don't know if you can help.

I mapped my serial gateway to /dev/MSgw because ttyUSBx tends to change when unplugging / replugging multiple USB devices into the computer (raspberry pi in my case).
I've also got a 433MHz gateway attached and when debugging have to unplug it sometimes.
When trying to start OpenHAB with /dev/MSgw as gateway address I get this:

2016-02-14 10:58:33.418 [DEBUG] [.b.m.internal.MySensorsBinding] - activate
RXTX Warning:  Removing stale lock file. /var/lock/LCK..ttyUSB1
2016-02-14 10:58:34.048 [ERROR] [.o.b.m.internal.gateway.Serial] - Unable to find Serial port '/dev/MSgw'

Do you know how/if I can still you my own custom paths to the gateway?
Now I changed it to ttyUSB1, but that port might change after rebooting.

Note2: If you are using non standard serial ports you have to adapt start.sh to have the serial port included. the java command line should then include the following parameters:

-Dgnu.io.rxtx.SerialPorts=/dev/ttyAMA0
whereas ttyAMA0 is the path to your serial port. Please be aware to change all scripts you might use for startup (debug, automatic start in linux,...)

@bkl Great work, much better than using rules. For me it worked on the first try. I will be very happy to test what I can.

Just one question, can we only read sensors, or can we interact, as in a relay switch? I tried to use V_LIGHT to add a light switch and got this log "Binding configuration of type 'mysensors' of item ‘Relay‘ could not be parsed correctly.
org.openhab.model.item.binding.BindingConfigParseException: Invalid Type: V_LIGHT"

Thanks

Hi, made some more test, and saw that bidding suggests that I use V_STATUS, so I did. Now I can see the change in the relay status and I can even turn it OFF by the OH inteface, but I can´t turn it ON. Maybe I can´t turn it on because I use inverted logic, where High is OFF, does any off that makes sense?

Thanks

Tested on openhab 1.8. works very well. Thanks!

@andredts
Can you try and post the sketch you are using? Or are you using the RelayWithButtonActuator Example?

I don't thing that the inverted logic should have anything to do with it.

andredts

@bkl
Hi, I´m using the MultiRelayButton 0.9b sketch, that I found here in the forum:

0_1456141716367_Bot_es_relays.ino

If you like I can try RelayWithButtonActuator Example, but I like the other better because it works when the server is down, no aka from server to make the state change.

@andredts
It was a bug in the code. If you download the new jar then it should be fixed.

andredts

@bkl
Thanks, I will give it a try and return to you with feedback.

@bkl
Working beautifully. I have three relay and three switches on the arduino, and no matter how fast I press them I got no miss command. Thanks

I got one bug, but I think it is Openhab's, when I changed the item file with Openhab running and the switch in the user interface got inverted ON-OFF and OFF-ON.

Hi,

Today I was testing Motion and Door sensors. Motion worked as expected, but the door sensor only works if it's set in OH as a "switch" item(on and off feedback), if you set it as a "contact"(open/closed) item you get the log: " No item configured for "5;1;V_TRIPPED". I have used the example sketch for the sensor

nikos1671

@andredts I also notice this with the door sensors. Normal the item must be contact and not switch.

bkl

@andredts
Thanks for the feedback, this is now fixed.

andredts

@bkl
Thank you for your great work. Happy to help with what I can.

Already tested and fully abandoned rules for setting up OpenHab with Mysensors.

Next I will try a analogic read, based on the dust sensor.

andredts

@andredts
Using this bidding for 15 days, with 3 relay, a Micro Sensebender, Humidity, Motion and Water level (base on dust sensor). And everything is working great.

Thanks again.

Hi.
I just added your binding and I am very happy for it because I have spent quite some time to figure out, how do I integrate mySensors in to Openhab.

My setup
RPI2
did apt-get update && apt-get upgrade
OpenHab (openHAB runtime has been started (v1.8.1))
I have NRF24L01+ connected directly to RPI using SPI.
I am running PiGatewaySerial service and Iam able to see communication when i do

sudo cat /dev/ttyMySensorsGateway

for example

7;255;3;0;15;0
7;255;0;0;17;1.5.4
7;255;3;0;6;0
7;255;3;0;11;Humidity
7;255;3;0;12;1.0
7;0;0;0;7;
7;1;0;0;6;

My problem is that openHab is unable to access /dev/ttyMySensorsGateway
I see error in my logs

2016-03-11 23:30:11.288 [ERROR] [.o.b.m.internal.gateway.Serial] - Unable to find Serial port '/dev/ttyMySensorsGateway'

        at org.openhab.core.service.AbstractActiveService$RefreshThread.run(AbstractActiveService.java:173) ~[na:na]

I found @BastienVH post and modified /etc/init.d/openhab JAVA_ARGS_DEFAULT section and added at the end of defintion

 -Dgnu.io.rxtx.SerialPorts=/dev/ttyMySensorsGateway"

and restarted service

Sadly, there was no change.
Please can you help?

Thank you.

@Pavel-Hrudka

I use RP2 with internal serial connected directly to ATmega328 chip. So it is also a unconventional serial. And for that to work I had to put the line " -Dgnu.io.rxtx.SerialPorts=/dev/ttyMySensorsGateway" on my start.sh file, before the line that has ".jar"

Hope it helps

andredts

@Pavel-Hrudka

On my last post I miss lid you, copping your own line, but actually to use raspberry internal serial you have to add to Openhab's start.sh "-Dgnu.io.rxtx.SerialPorts=/dev/ttyAMA0 " before the line with the ".jar" because the serial got to start before you run the biddings.

Hope it helps.

Pavel Hrudka

Hi thank you.
I solved my issue, but when I wanted to update my post, the thread was locked.

Here in this post its said that I should create link to virtual port like this

sudo ln -s /dev/ttyMySensorsGateway /dev/ttyUSB20

Pointing OpenHab binding to this port solved my problem.

I did try to add command line parameter to /init.d script for OpenHab but that did not work.

Cheers.

Hi I am new to openHAB how do you configure a relay node? I do see the node in the logs but the relay don't what to switch on or off. I have my temp and humidity sensors working already.

18:38:50.450 [INFO ] [.b.m.internal.MySensorsBinding:257  ] - New MySensor sensor found (Dimmable device of some kind): node-id=95, sensor-id=0 with type S_DIMMER
 * Example item: 95;0;V_STATUS             - Binary status. (on/off)
 * Example item: 95;0;V_PERCENTAGE         - Percentage value. 0-100 (%)
 * Example item: 95;0;V_WATT               - Watt value for power meters
