openHAB 2.0 binding

[LastSamurai]

Hi, just a short question as I haven't found any up to date information about it: I am thinking about switching from domoticz to openHab 2 (as I really like the new UIs and the auto discovery). I am using an ESP8266 based MQTT gateway. Does openhab 2 on a raspi work with Mysensors using MQTT and does it support the new sensors/actor types added Mysensors 2 (specially RGBW)?

Thank you!

[Fabien]

Yes you can using proxy items and rules. see example here : https://github.com/mortommy/MySensorDioder
But why not switching to ethernet/serial gateway with @TimO OH2 plugin ?

[LastSamurai]

Thanks @Fabien I have a serial gateway too, but I liked the idea of a MQTT gateway more because its much more flexible. Does Tims plugin not support MQTT? I wanted to use that.

Hi @LastSamurai , currently Timo is working on MQTT gateway but I don't know precisely when it will be available to all.

@TimO said in openHAB 2.0 binding:

@Fabien Thank you for your feedback!
And: I've waited for that question according firmware updates to come up. :-D

I've looked into it and I'm very interested but till now there is only the implementation in the library, I've not seen an implementation in a binding. I'll continue to look at it, but with low priority. :-)

Current priority list is:

1. Include binding in OH2 repository.
2. Test and include the big refactoring from @andreacioni .
3. Add MQTT gateway (proof of concept working, full integration after refactoring).
4. Add little feature requests, add sensors ...

[LastSamurai]

Ok, I will keep an eye on this one and stay with the serial gateway for now.

After moving from my ubuntu laptop to RP3 I have had success!!
Flashed the sd card with the latest openhabian, waited for everything to auto install on the RP3 and could then install the my sensors (ethernet) gateway on the pi and also open a karaf console to log openhab2 via a remote/headless ssh. My remote browser could open the paper ui via openhabianpi:8080 and I added the ethernet gateway successfully. Adding the motion sensor needed the node id 2 and child id 1 as set by the Arduino sketch. The light level sensor was then turned on and it just showed up as my sensors (2,2) in the paper ui inbox so this level of discovery works! The sensors now show tripped status/light level in the paper ui control.
Looks like I can now progress to using My Sensors to control the mi-lights already working in openhab2.
Thanks Tim for all your work on the binding

@TimO , I just noticed a weird behavior - I've changed configuration for another binding and restarted it from the console but that killed mysensors binding:

Complete stop/start of OH is the only solution so far.

[andreacioni]

Hi @AndrewZ , yes this is a known issue (I just openend an issue here) with the binding. Just out of curiosity, have you changed something in things file?

[AndrewZ]

@andreacioni thank you
Yes, it was a change in the .things file, but it was related to another binding.

[andreacioni]

@AndrewZ things file update trigger a reload of all binding declared inside it, nothing strange. ;) Follow the above link to keep track of the status of this issue.

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:
