openHAB 2.0 binding

[LastSamurai]

I just tried to get the openhab 2 binding up and running. I have a serial gateway and domoticz + openhab running on a pi. I stopped the domoticz service and installed the serial and mysensors addons for openhab like mentioned in the github readme (bundle:list showed them both). I also added the openhab user to the dialout group.
I then created a demo.things file in config/things with

Bridge mysensors:bridge-ser:gateway [ serialPort="/dev/ttyUSB0", sendDelay=200 ] {
    /** define things connected to that bridge here */
  }

The log of openhab shows these errors though:

2017-03-19 00:03:59.855 [ERROR] [col.serial.MySensorsSerialConnection] - Can't connect to serial port. Wrong port?
2017-03-19 00:03:59.897 [ERROR] [col.serial.MySensorsSerialConnection] - Failed connecting to bridge...next retry in 10 seconds (Retry No.:46)

Any idea why? This works just fine:

cat /dev/ttyUSB0

[AndrewZ]

@LastSamurai please check the group ownership

$ ls -l /dev/ttyUSB0

Make sure the port you're using is included in EXTRA_JAVA_OPTS as described here

[LastSamurai]

Thank you, that helped! Should anyone ever face the same problem: after changing the EXTRA_JAVA_OPTS I also needed to restart openhab (more likely the java vm).

[LastSamurai]

So openhab is running now and discovers my sensors when I restart them while scanning. My RGBW controller nodes pop up as RGBW sensors though. The on/off switch works, but what do I have to do to actually control the colors?
I tried editing the 4 variables but that doesn't seem to change the lights.

[TimO]

@LastSamurai : What does your sketch expect? One ASCII formated RGB code like described here: https://www.mysensors.org/download/serial_api_20 or a value between 0 and 100% per color (r,g,b,w)? I see different implementations (in openhab and in mysensors) and maybe we have to adjust the binding.

[LastSamurai]

@TimO Right, I guess thats the problem. I have written my sketch against domoticz, so it expects either a 6 bit hex string (rgb = e.g. ff00ff) or a 9 bit (idk why) rgbw hex string (e.g. #ff00ff00).
According to the mysensors docu "ff00ff00" would be right, I guess.

[AndrewZ]

Just noticed in the log:

[WARN ] [.discovery.MySensorsDiscoveryService] - Cannot automatic discover thing node: 0, child: 255 please insert it manually

Is that normal or any additional configuration is needed?
Thanks!

[TimO]

@AndrewZ hmmmm, a child that represents itself with an id of 255 shouldn't exist. 255 is used for battery status for example. What's the message that comes in before that?

[TimO]

@LastSamurai I'm working on a solution! RGB seems easy, but I haven't looked at RGBW. The Colopicker in OpenHAB only sends RGB.

[AndrewZ]

@TimO here is the output:

2017-03-23 20:51:32.531 [INFO ] [ui.habmin.internal.servlet.HABminApp] - Started HABmin servlet at /habmin

2017-03-23 20:51:33.772 [INFO ] [al.protocol.ip.MySensorsIpConnection] - Successfully connected to MySensors Bridge.

[TimO]

@AndrewZ the message occurs right after startup and before the bridge gets connected?! Just ignore the message if everything else is working fine. :D
I'll release the refactored version soon. It's already available via the new IoT marketplace.

[AndrewZ]

@TimO yes, message occurs on startup and I'm already using version from marketplace, I see it as market:binding-3328323 - 1.0

[TimO]

@AndrewZ oh okay! I will look at it!

[LastSamurai]

@TimO Cool, I'll test it once you are done. Domoticz only allows to either use the white channel or a RGB value (without the white) at the moment. Perhaps it can be done similarly in openhab.

[TimO]

@LastSamurai Could you please take a look at this: https://github.com/tobof/openhab2-addons/issues/76 ?

I've added the RGB & RGBW channels and because I'm not that confident about the RGBW implementation I'm kindly asking you to test the implementation and give me some feedback. :-)
The conversion from HSB, which is used by OpenHAB2 internally, to RGBW left me pretty confused. ;-)

[LastSamurai]

I'll test it. Might take some days to get to it though ;)

[balder88]

I found the solution myself. About a week ago i upgraded the binding. And it worked.
Everything seems to work as it should. Except I can't recieve var1 (custom) for neither the hum or temp child.

smartSleep is nice. I use it once an hour (regular sleep every minute) to get configurations from openhab about sleep time and other small things in the code.

@balder88 said in openHAB 2.0 binding:

Hey guys, first message on this forum. Been reading alot before. But now I have a problem I just can't solve.
It's about smartsleep with openhab 2.
Im using wifi gw rfm 69.
Regular messages works as it should both ways.
But it almost seems like the smartsleep isn't enabled in the binding.
Here are my configs and logs.

What am I doing wrong?

[antonholmstedt]

First I want to thank you for this binding, got it working with my esp8266 gateway without any problems at all. However, I want to ask how the reconnection problem is developing, any plans to solve it or is it not possible? I've tried to scan the thread but didn't find any information regarding it.

[Alpoy]

Thanks for making this binding! :)

One question, is there a specific reason motion (tripped) sensors have to be Contact items?
In OH2 all the Z-wave motion sensors are Switches (AFAIK) so it would be nice if the mysensor PIR's could also be Switches so I can just add these to my existing motion sensor groups and rules.

(I tried setting a triggered channel as Switch but it didn't work)

[andreacioni]

@Alpoy check this discussion on GitHub. The question is still open.

@antonholmstedt reconnection is currently implemented in binding (look here). Feel free to open an issue if you experience reconnection fails in your environment :smiley:
