My things file :

  waterQuality    OrpPiscine  [ nodeId=211, childId=0 ]

  cover           VoletBureau [ nodeId=42, childId=1 ]
}

[Fabien]

It works when I set networkSanCheckEnabled=false
Why ? before update I have no problem with this.

[Fabien]

And just another "problem". When I send UP command to my roller shutter node and after a stop, node send me :

17:44:50.032 [DEBUG] [rsAbstractConnection$MySensorsReader] - Message from gateway received: 42;1;1;0;3;81

but Item VoletBureau is not updated with this value.

@Fabien

Thanks for reporting!

1. NPE: it is fixed now. I've made a mistake while renaming the parameters.

2. Did that ever work? I don't recall changing that logic lately. I've added the code now. Could you please test it and give me a feedback?

[Fabien]

@TimO
It works fine now for 1 and 2. If I remember you send me a version few month ago wich updating dimmer value.
Thank you !

[LastSamurai]

@TimO I have a small problem here. I was trying to get into openhab (again) this time using your new 2.2 binding. I removed the old jar and installed the new one. I had also removed all things in the paper ui before. Afterwards I tried to add the gateway via things file again.

Bundle:list says:

190 | Installed |  80 | 2.2.0.201707241115     | MySensors Binding

but this things file:

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

Only results in an error message:

22:49:56.806 [INFO ] [el.core.internal.ModelRepositoryImpl] - Refreshing model 'mysensors.things'
22:49:56.847 [WARN ] [el.core.internal.ModelRepositoryImpl] - Configuration model 'mysensors.things' is either empty or cannot be parsed correctly!
22:49:56.988 [INFO ] [el.core.internal.ModelRepositoryImpl] - Loading model 'mysensors.things'

Any idea what I did wrong? The port is right I can receive messages via cat /dev/ttyUSB0.

PS also is there already a timeline for when you will be able to add this binding to the official openhab "store"?
PPS The binding also doesn't show up in the menu where you can scan for new things. Is there something more to do to install this new version? The old one was working.

[TimO]

@LastSamurai Looks like the binding wassn't initialized. There should be a message in the log why the init failed. My guess: gnu.io is missing. Did you execute this step: feature:install openhab-transport-serial?

I can't give you a timeline about the integration. There is a PR here: https://github.com/openhab/openhab2-addons/pull/2066

It took me quite some time to fulfill all requested changes and I'm now waiting for a review by Kai Kreuzer, the owner of the Repo.

You are able to install the binding via the IoT Marketplace: https://community.openhab.org/t/distributing-bindings-through-the-iot-marketplace/24491

MySensors Binding:
https://marketplace.eclipse.org/search/site/mysensors

A big disadvantage: Requirements are not fulfilled automatically. This will be added in the future. You have to execute the command above (before installing the binding) in the karaf console: feature:install openhab-transport-serial.

[Feji]

Hi,
When I use the 2.2.0-SNAPSHOT version of the binding, the zwave binding can't initialize the serial connection to the zwave dongle. With no mysensors things, it's OK. I made a ticket on git. I revert back to 2.1.0-SNAPSHOT and it's OK.

[LastSamurai]

@TimO Thank you. I installed the transport-serial feature (again... I had it installed for the last version of the binding already) and now its working.

[TimO]

@Feji I've updated the issue on github.
https://github.com/tobof/openhab2-addons/issues/86

[philro]

Hi,
thanks for the new Version! I've got a Problem with the Network Sanity Check, it doesn't run.

I got a ESP8266 Based Ethernet Gateway which is configured with DHCP. Everytime the DHCP Lease got renewed the Connection between the Gateway and openHAB is lost for a short Time. The Binding doesnt' recognize this. The Gateway and all Sensors marked as Online but not a single Message comes from the Gateway. I could also reproduce this if i reboot the Gateway.

I tried different Settings for the Sanity Check but nothing worked.
I switched to Debug-logging for the Binding. After the Connection is lost, not a single Log Entry is written.

If i go into the Settings from the Gateway thing and change something, the binding start to communicate with the Gateway again, but all Sensors marked as offline in openHAB. There are incoming Messages from Sensors but the Binding write to log:

20:35:10.030 [DEBUG] [rsAbstractConnection$MySensorsReader] - Message from gateway received: 5;2;1;0;1;67.9
20:35:10.036 [DEBUG] [rs.internal.gateway.MySensorsGateway] - Node 5 found in gateway
20:35:10.041 [DEBUG] [rs.internal.gateway.MySensorsGateway] - Child 2 not present in node 5

if i restart whole openHAB all is functional again until the next time this occurs.

Thanks for help,
Greets Phil

Edit: I also get the same Log entries as above if i change a Setting from the sanity check, without rebooting the Gateway.

[Feji]

Hi, tobof. Thx again for the serial fix :).
However I had this issue with the power counter node :

09:16:02.900 [WARN ] [rs.internal.gateway.MySensorsGateway] - Variable V_WATT not present
09:16:03.285 [WARN ] [rs.internal.gateway.MySensorsGateway] - Variable V_KWH not present

The Gateway and the node are in 2.2.0b, Openhab in 2.2.0 SNAPSHOT.

[TimO]

Hey @Feji !

When did that message appear. Could you please post the log before and after the warn message ocurres?

[Feji]

Hi,

this is the entire log.

[Feji]

@Feji
I found it, the "Revert State" option was activated for this node. Now it's working as expected.
The log message might be more "explicit".

[tbowmo]

@TimO

Trying openhab2 out.. Fresh install, with both serial and mysensors binding installed.

I'm using socat to make a virtual comport to node-red

In the openhab logs I see a lot of errors like

I can see that the gateway indeed does answer to the 0;0;3;0;2 request, and the reply is also send on to openhab2.

I have tried to disable startup checks, but I get ERROR 409: conflict as a toast message in the lower right corner of paperui when I try to save settings.

Anything I have missed somewhere?

[MagnusF]

@TimO
I'm new to MySensors and openHAB and this might be vary basic questions.
As I only have start with a small system with openHAB on an RPi3, a serial gateway and 2 nodes so the update to openHAB 2.2 binding will probably not be a big deal.
In the explanation of the changes, you write "The current release is not backwards compatible" and "I hope this won't happen again in further versions!". Does this mean that a new version is backward compatible with e.g. V2.1.0 or that I in anyway must do the reconfigurations now but don't have to do it again?
I have configured my things in Paper UI and have to delete them but do I have to clean the *.items file and *.sitemap file? Further down in the "topic" you have a link to "https://github.com/tobof/openhab2-addons/issues/86" with a link to a new version of the binding and I wonder if this is the one I'm going to use?

[Feji]

@MagnusF
This version of the binding is for thus want to use two or more serial connection with openhab.
Before delete all your things configured in PaperUI, you should consider to dedit the org.eclipse.smarthome.core.thing.Thing.json database in /userdata/jsondb/ and delete the " " around the nodeId and childId. Before editing this file, you must stop your openhab.

[MagnusF]

@Feji
Thanks for your replay! But unfortunately, that was not an answer to my thoughts.

1. You say "This version..." Do you mean to use two "MySensors Serial Gateways" connected to one controller with OpenHAB?
   Does this mean that if I connect one more "MySensor Serial Gateway" to my controller that I will have one more "MySensor Serial Gateway" thing but with another bridge definition?
2. In the file "org.eclipse.smarthome.core.thing.Thing.json" there are no things defined with i.e. nodeid="1" and childid="2" it looks like this
   "mysensors:temperature:709db93f:temperature_2_1" i.e. nodeid 2 childid 1. Do I look in the wrong file?

[LastSamurai]

After I fixed the initial errors with the help from this thread I am now trying to use my RGBW nodes with openhab. I have had several issues with that though:

• If I add the item via the paperUI:
  • On/Off (status) works just fine
  • Setting a color at full saturation/brightness works well too
  • I am not sure if that is intended but I want to use only the white leds on the RGBW strip sometimes. Mixed white values just look very bad. I can't seem to be able to do this with openhab. Settings the saturation slider to 0 sends ffffffff and sometimes just 00000000. Is there any way to just send 000000ff? Domoticz does this automatically when setting the color to white and home assistant has a seperate white slider that should allow the same thing
  • When trying to change the brightness the node only receives a new color value of length null (no dimmer message) and I get the following error message in the openhab log:

I had no success at all trying to define the things via the things file. I described my setup and the problem here. (Short version: definition via node id doesn't seem to work for me and I have no idea what items/sitemaps to use to control the rgbw nodes).
Any help would be great (@TimO )
