openHAB binding

If you make a guide to make openhab work with a non standard serial port, then i will make it part of the first post.

Hi,

I'm trying to control curtain with UP/DOWN/STOP commands, but it does not work.

I am going to give this a try with the serial gateway. I am not sure whether to use mqtt or serial; this might help me make up my mind!

Hi all,
can we please document this binding and add it to github of openhab in similiar way to all other bindings? I can help with doing so:)

@bkl
Just wanted to say thanks for making my wish come true!

My Experience Setting up OpenHab
If it helps others, I tried OpenHab a year ago but gave it away simply because of the instabilities associated with using MQTT, i.e. needing a server, a broker, a client and the gateway. Far too many modules to configure, making it so easy to get it wrong.

Thanks to this MySensors/OpenHab binding, the Arduino gateway talks direct to OpenHab without all the middleware, making it easier to configure and more reliable.

It took only a few minutes to install OpenHab 1.8 and this binding. Pasted the items and sitemap examples and presto - it was working! A very pleasant change from nearly three days wasted trying to get the (alternate) OpenHab2 binding working.

I'll upgrade to OpenHab2 when I'm confident it is stable and the matching binding is sorted out.

Hi
I have setup openhab on my pi 2 and I can see the gateway and a motion sensor with the following output in the openhab log:

"no item configured fo "1;1;V_TRIPPED" seems to be confusing me. I have entered the motion sensor into the items file as in the example so can you point me in the direction to correct this please?
I am very impressed so far, easier to get to this stage than it was using insteon!

@hek @bkl
Just want to say a REAL BIG THANKS for this binding and for the whole mysensors system.

I have been trying to use openhab 1.8 for my PhD project and I initially setup insteon and had so many headaches I gave up in disgust. I was pointed in the direction of mysensors as a possibility and I thought I had nothing to lose.
Not only is the binding a success, I have two motion sensors running, one on a pro mini with 2xAA batteries running it as a test and one on a uno, I have persistence running and successfully logging the status of my devices on each and every update! I am using mongodb for the persistence methods as I love nosql, even though I have to teach relational databases at the moment, (trying to turn the Uni onto the light side).

Anyway, for those interested, here is a log from the db:
{
"_id" : ObjectId("574acbe1e4b0cd9ed18ada26"),
"item" : "DiningRoom",
"realName" : "DiningRoom",
"timestamp" : ISODate("2016-05-29T11:00:49.761Z"),
"value" : "ON"
}
{
"_id" : ObjectId("574acbe3e4b0cd9ed18ada27"),
"item" : "DiningRoom",
"realName" : "DiningRoom",
"timestamp" : ISODate("2016-05-29T11:00:51.136Z"),
"value" : "OFF"
}
{
"_id" : ObjectId("574acc25e4b0cd9ed18ada2a"),
"item" : "DiningRoom",
"realName" : "DiningRoom",
"timestamp" : ISODate("2016-05-29T11:01:57.823Z"),
"value" : "ON"
}

the .items file looks like this, (so you can see the naming strategy)

Switch DiningRoom "DiningSensor [%s]" <motion> (GF_Dining) {mysensors="1;1;V_TRIPPED"}
Switch LivingRoom "LivingSensor [%s]" <motion> (GF_Living) {mysensors="2;1;V_TRIPPED"}

.All in a brilliant success. Now to play with the rules and add lots of new sensors.
THANKS AGAIN!!!!!

A Short Followup

I've had this binding running 24x7 for a week or more and it has been faultless! - Thank You!

For the newbie attempting to get OpenHab up and running, this is the answer, the only answer! It's so clean and simple, download OpenHab (1.8) and this binding and run.

Cheers,

Paul

I am amazed by your work @bkl !
I have a few question for you:
Can I use your binding somehow to integrate RGB light in openhab with the color wheel? I have some programmable rgb ledstrip that I was thinking about integrating into openhab, but I am unsure how to do this. I was thinking about using the color widget in the sitemap together with a DMX syntax:

if my led strip has 56 diodes

Color rgb_strip_living_room "RGB Ledstrip Living Room" {dmx="CHANNEL[0-56]"}.

But then i could also use the same ledstrip in 2 by setting two different color like

Color rgb_strip_living_room2 "RGB Ledstrip Living Room" {dmx="CHANNEL0-23]"}
Color rgb_strip_living_room3 "RGB Ledstrip Living Room" {dmx="CHANNEL24-56]"}

Then I would also like to send IR commands from OH to mysensor, have any of you done that?

Keep up the great work, and let me know if I somehow can help with expanding/documenting the binding.

The sketch may be a bit over complicated, but the important part is the incomingMessage, all the rest is because I like to fade between the colors.

Hope it help you.

@bkl Thanks for your code, just to be sure, you only have 1 LED in your LED strip? NUM_LEDS = 1 or does that define child ID? In mine I have 38, 52,43,78,23,67 leds in my ledstrips. How can I modify your code to be used as locally attached sensor on the gateway? Also I have 6 ledstrip connected to my gateway.

bkl

@skatun

My code was just to show how the integration between openhab and mysensors is working.
And correct my led strip is controlled by a single P9813 chip,

You could try and change NUM_LEDS but this will also increase the number of Sensors in openhab/mysensors
Or you could group them togetter in the sketch.

Is it possible to change de default baud rate for the 1.8.0 binding? As I'm using a 8 MHz mini for my serial gateway I would like to set the baudrate to 38.4 kbps.

I read that this would be possible for the Openhab 2.0 binding but I'm reluctant to move to Openhab 2.0 as its only a beta at the moment.

Is it possible otherwise to compile a new jar with this lower baud rate? I guess two versions would be enough, 38.4 and 115.2.

Thanks!

I've been trying to get a mysensors node which is using an nRF24L01+ to transmit to a directly connected nRF24L01+ on a Raspberry Pi 3 running PiGatewaySerial. When I start the gateway I get

Starting PiGatewaySerial...
Protocol version - 1.4
Created PTY '/dev/pts/0'
Gateway tty: /dev/ttyMySensorsGateway

Following some other instruction I created a link to /dev/ttyUSB20 so that openhab could recognize it. I have Openhab with your serial binding in the addons folder. I am having difficulty with the binding. I feel like I have made a tiny bit of headway but it doesn't seem to be able to bind with it. In the openhab debug log I get:

2016-07-16 14:39:15.537 [ERROR] [.service.AbstractActiveService] - Error while executing background thread MySensors Refresh Service

@NickBuilder

Hi

No need for a new version, baudrate is configurable

just set.
mysensors:baudrate=38400

NickBuilder

@bkl

Thank you @bkl! That is the best answer I could have wished for. :)

I've actually tried some similar prefixes to the port definition, such as "...:38400" and "...@38400" etc. I haven't found any documentation describing the available binding settings more than the port definition that you mention here at the top. I guess the documentation will be more complete for the Openhab 2.0 binding description.

Thank you for your great work here!

but nothing else .
I tested lot of sensor but still same error.
Have you any idea ?
Thanks

@Peter-Šuľaj I'm fairly new to this stuff, but curious if you are trying to auto-assign node ID? I don't believe the MySensorsBinding supports auto-assign so you have to define it as static and use:

#define NODEID  3 //or whatever

//and then call this in your setup instead of Sensor.begin();
Sensor.begin(NULL, NODEID);

in your script. Again, not sure if this is your problem but I figured I would chime in.

Hello again!

Is there also support for sending the ack bit from the gw in some way? I saw that this is actually possible in the 2.0 binding. If it's possible how is a "not ack" handled? This would be very useful for e.g. a relay sensor.

I also noticed that you're not the author of the 2.0 binding, I'm sorry for making that assumption.

Thanks!
