openHAB 2.0 binding

[matt shepherd]

I've been trying to figure this out for a while. For me openhab discovers 4 things Red, Green, Blue and Status. These are all dimmers and I can't get them all to work together as 1 colour wheel? They all work really well independently but that's as far as I got. I've also tried the .items file but with no luck.

Hello!
I just started to play with OpenHab2 and new binding? thank you for great work.
But, i discover some strange behavior:
Openhab2, ethernet gateway, 3 mysensor nodes, all nodes sucessfully detected and configured in PaperUI, but some data looks like not updated. Looking to log i note some suspicious lines like:

00:28:47.077 [DEBUG] [rsAbstractConnection$MySensorsReader] - 3;1;1;0;0;24.6
00:28:47.078 [DEBUG] [rs.internal.gateway.MySensorsGateway] - Node 3 found in gateway
00:28:47.078 [DEBUG] [rs.internal.gateway.MySensorsGateway] - Child 1 found in node 3
00:28:47.078 [WARN ] [rs.internal.gateway.MySensorsGateway] - Variable 0 not present

Sorry, i don't know how to dump OpenHab configuration, but item configured.
Any suggestions?

@matt-shepherd What works for me :
items - just used 1 channel, V_VAR1, but you could keep them separate

String neoPixelRgb           "RGB LED string"                           (grpLighting)  { channel="mysensors:rgbLight:ethGateway:rgb01:var1" }
Color neoPixelColor         "RGB LED string"            <colorwheel>    (grpLighting)

rule

rule "Set RGB value NeoPixelStrip"
when
    Item neoPixelColor changed
then
    val hsbValue = neoPixelColor.state as HSBType

    val brightness = hsbValue.brightness.intValue
    val redValue = ((((hsbValue.red.intValue * 255) / 100) * brightness) / 100)
    val grnValue = ((((hsbValue.green.intValue * 255) / 100) * brightness) / 100)
    val bluValue = ((((hsbValue.blue.intValue * 255) / 100) * brightness) / 100)

    val rgbHexString = String::format("%02X%02X%02X", redValue, grnValue, bluValue)
    sendCommand(neoPixelRgb, rgbHexString)
end

parsed in node

  if (message.type == V_VAR1)
  {
    // Write some debug info
    Serial.print(", New status, V_RGB: ");
    Serial.println(message.getString());

    // starting to process the hex code
    String hexstring = message.getString(); //here goes the hex color code coming from through MySensors (like FF9A00)
    long number = (long) strtol( &hexstring[0], NULL, 16);
    RGB_values[0] = number >> 16;
    RGB_values[1] = number >> 8 & 0xFF;
    RGB_values[2] = number & 0xFF;

    colorWipe(strip.Color(RGB_values[0], RGB_values[1], RGB_values[2]), 50);
  }

@TimO Hey all, looks everything seems to work now, but now i have defined the bindings by the paper UI, and work with the rule definition as show by 'doctor64' ....
thanks for the help

@FusedHe3 Thank you for testing and your input!

The sketch you are using is representing itself as a RGB sensor and the log you've posted looks good.

About the fiddling with the .items file and the color picker: Thank you! That should'nt be needed anymore, I've changed it here: RGB-Test-Binding

[TimO]

@RVMRVM The definitions carlyler posted looks fine and I've tried to implement this logic into the binding so you won't need the rule anymore. Feel free to test my binding or stay with the rule. Hopefully both would lead to the same result. :)

[TimO]

Hey @doctor64 !

Please open a new topic. This one is getting really huge. :-)

Please check if the temperature channel is linked. In PaperUI you may do this by moving to "Configuration" -> "Things" and click on the sensor data.

[FusedHe3]

@TimO No problem, glad to help!

I'll try to alter the sketch and use the new version of the binding as soon as I have my LED strip running again.

[RVMRVM]

@TimO Perfect, is OK for RGB & RGBW... but now the datastring you send is a decimal string, not a HEX-string as they used normal, it is not a big problem to change this feature in the node script, if you want to have a decimal string.
How do you handle the white color, becaus this is not included in the datastring info. maybe by a switch and a other variable .
something like this:

@RVMRVM Interesting. Do you have a corresponding log for me?

Here's my test:

[INFO ] [arthome.event.ItemCommandEvent:43   ] - Item 'mysensors_rgbLight_8a7ca179_rgblight_199_0_rgb' received command 71,46,91

@TimO this is the log of the node:

this is the result from the rule routine:
15:39:17.479> 10919 TSF:MSG:READ,0-0-23,s=1,c=1,t=26,pt=0,l=6,sg=0:FF5E28

[doctor64]

Hello @TimO !
I delete all things and items (btw, seems like items not deleted completely, and re-apperas after item re-create), create things again and not see error anymore. Some black magic in action, looks like.
I will create separate topic if this issue appears again. Thank you!

[FusedHe3]

@TimO Just tried the changes you made. Color picker now worked straight away! :smile:

I also checked the sketch and it seems to be declaring itself as an RGB Light, not as a sensor. But could it be that what I see in the PaperUI are just the labels that still need to be changed?

void presentation()
{
  // Send the Sketch Version Information to the Gateway
  sendSketchInfo(SN, SV);
  present(CHILD_ID_LIGHT, S_RGB_LIGHT);
}

One last question: the Variable 2 not present error I get everytime a command is send, is that because those two variables aren't set in the sketch I'm using?

Thanks!

Hi,

just a quick question:
OpenHab2 can be used without touching any code right?
I use mysensors serial gateway. Tried to set it up all day yesterday from skratch. Also with OpenHabian. But no success.
So it seems i still have to edit files and folders manually in order to get it running right?

I got Domoticz working after short time. Was expecting OpenHab2 makes it even more easy :/

[TimO]

@FusedHe3 Please enable DEBUG mode in the karaf console and paste the output around Variable 2 not present here.

[TimO]

@edsteve Yes, that's one goal of the binding. For the serial gateway the hardest part is to determine the path of the serial port. Something like: /dev/ttyUSB0 or /dev/ttyACM0 if you're using Linux.

What exactly does not work? Please attach a log from the karaf console.

[edsteve]

@TimO
I use Nano Neo as Hardware with Armbian Linux and OpenHabian on top. The bundle:list showed me mysensors.
I don't find any Things. Where do i have to put this info: /dev/ttyUSB0 or /dev/ttyACM0?? In which config file?
Now i get an error with karaf saying "connection refused" when i try:

ssh -p 8101 openhab@localhost

Yesterday it worked... the karaf thing make it even more difficult.

EDIT: I just found out that i have to make a demo.things file with the code for the serial gateway.... And for sure that was not the last file which needs manual editing. I go back to Domoticz. Till OpenHab becomes same easy.

[FusedHe3]

@TimO Thanks for investigating!
Here's the log, but I don't know if it's of any more help.

I guess it may have something to do with a V_light and V_dimmer answer that is being send by the node. (As a reminder: I'm using this this one.)

@TimO So I finally got around to testing the RGBW version of the plugin. I tested it with one sensor (light and the battery voltage) and an RGBW node.

Results:

• RGBW color settings works well. Its a message of lengths 8 (e.g. 00ff5100) instead of the 9 from domoticz (#00ff5100). So I had to change my node's code. But your solution looks cleaner, so I guess thats fine :+1: What didn't work are all the other values beside "color". As you can see I changed the variable 1-4 and it gets send to the node as message type 24-27, which are custom variables... why did you use these?
• RGBW on/off did not work. The "status" button does nothing. Log below. Would be nice to have a button to send on/off commands to the nodes.
• Light and Voltage sensors seem to work just fine

By the way, short question about openhab 2: what is the difference between things and items? Seems like items/sitemaps are used in the "old" frontends to display sensors/actors. Are things the same for the new paperUI? I have just used that one yet. And why do I have to declare the gateway in a file while the rest is auto discovered (also it seems like some of you also added their sensors to the file with the gateway definition)?
Seems to be hard to find up-to-date easy information on these things, so thanks in advance for an explanation.

Log from the status button:

22:55:02.378 [INFO ] [smarthome.event.ItemCommandEvent    ] - Item 'mysensors_rgbwLight_gateway_rgbwlight_10_1_status' received command OFF
22:55:02.402 [WARN ] [ensors.handler.MySensorsThingHandler] - Variable not found, cannot handle command for thing mysensors:rgbwLight:gateway:rgbwlight_10_1 of type status
22:55:02.440 [INFO ] [marthome.event.ItemStateChangedEvent] - mysensors_rgbwLight_gateway_rgbwlight_10_1_status changed from ON to OFF

[LastSamurai]

By the way has someone running openhab together with an echo (alexa)? I am currently trying to use that combination and at least with the RGBW nodes there seems to be no reaction (yet) to the commands.
