openHAB 2.0 binding

[kolaf]

For what it's worth, I'm using openhab 2 with a version from yesterday together with the latest my sensor binding I found here. Serial gateway and serial aeon stick zwave controller (latest binding from the build server). Absolutely no issues for me.

[BenCranston]

@kolaf I concur. I just refreshed everything to latest snapshots and holy smokes it all works. :) I'm watching my zwave rules and MySensors controls all working together. At this point, I'm not sure what was broken with my install, but both bindings are now playing with each other very well without issue.

[BenCranston]

I can report continued success with the MySensors binding playing nice with the Z-Wave binding. :) Today I'm working out some more rules and have a situation, where when a switch state is changed we send out command to another MySensor to change two childIDs on the same nodeID and another childID on a different nodeID. Two of the messages get out to gateway with the third not going out. Here's the debug:

2015-11-11 09:49:00 [DEBUG] [.b.m.p.s.MySensorsSerialWriter:40   ] - Sending to MySensors: 10;1;1;0;2;1

2015-11-11 09:49:00 [DEBUG] [.p.s.MySensorsSerialConnection:83   ] - 9;2;1;0;2;1

It appears that all three messages are queued, but only the first two are actually sent. I switched the order around in the rule to send the messages in a different order and only the first two make it out to the nodes. Do I need to delay some after each command? Anyone else able to reproduce this? Thanks.

the driving rule looks like this:

rule "g01_Stair"
when
        Item home_group_5a59cc99 changed
then
  if (mysensors_light_508ef404_Light_10_1_status.state == ON) {
    // sendCommand(mysensors_light_508ef404_Light_9_2_status, ON)
    sendCommand(mysensors_light_508ef404_Light_9_4_status, ON)
  }
  else if (mysensors_light_508ef404_Light_10_1_status.state == OFF) {
    // sendCommand(mysensors_light_508ef404_Light_9_2_status, OFF)
    sendCommand(mysensors_light_508ef404_Light_9_4_status, OFF)
  }
end

Hello Timo,
Great Work !!:smiley:

Could You suggest a good Tutorial for understanding how to develope Bindings for HopenHab2?
Anyway I will study your code too

Regards

I've been testing this on my side and I have to say that is excellent.

Very well integrated with the 'Things' discovery model for OH2, etc.

The only thing that is really stopping me to move forward is OH itself. I have several (and somehow disapointing) experiences that makes me feel that is still very beta. Not sure if anyone have any update on when the RTM is expected???

Great work @TimO ! ! !

[TimO]

@mirko-ugolini The documentation on how to develop bindings for OH2 is rather thin. :(
Starting point is here: https://github.com/openhab/openhab2/blob/master/docs/sources/development/ide.md

From that point I've looked into the existing bindings and into the eclipse smarthome documentation, that does not work all the time, but the concepts match.

If you would like to contribute to the MySensors binding I will gladly help you to find the entrance. :)

@BenCranston I will have a look at it. Thanks for testing! The queue currently is rather basic (but should work). Maybe the data is written too fast to the serial output. I have a similar problem with OH 1.X and my rules, where I need to define a delay between commands.

Something I plan to do, is adding the ACK functionality to the binding, so if no ACK is received the command is repeated for 5 times or so.

Yeah, I see your point. As far as I know there currently is no real roadmap for OH2, which is rather annoying. On the other side there is a really healthy discussion running on how to maintain the code. There are so many developers with bindings, bugfixes and pull requests that want to contribute, that the OH organisation has to change its structure.

At the moment the number of open pull requests for OH and OH2 is huge, so I hesitate to give the MySensors binding a shot.

+1 for the ack functionality. In my opinion this is a Transport-Layer functionality and should be built into the gateway (Arduino or whatever) itself. But the main developer doesn't like the idea because he is fearful that the serial buffer (or even an arduino queue system) will be unable queue enough messages while resends happen.

On the other hand: we have plenty of RAM on our openhab hosts, so your idea seems like it will solve the problem completely, because we could even react on continous fails with putting the device offline (or whatever the openhab2 terms are for this) :grin:

[TimO]

@BenCranston : I'm pretty sure now, OH2 is sending the data too fast, because if I use terminal emulation instead of hardware all three commands are transmitted.

Just curious: are you using an ethernet or serial gateway?

[TimO]

I've added an option to influence the delay between messages send to gateway.

Possible values are 1 to 1000 milliseconds.

[kolaf]

@TimO Would it be too much trouble for you to implement support for S_MULTIMETER? It seems that this is required for me to get the voltage reading from my battery driven sensors. Alternatively, is there anything you can do with the battery percentage that is sent using sendBatteryPercent? I don't know if OH2 has any notion of the sensors battery level?

I notice you have support for the type S_VOLTAGE, but I cannot find that this is present in the master branch of MySensors?

[kolaf]

Also, from where can we download the latest versions of your binding?

[kolaf]

And finally, GREAT WORK :-)

[TimO]

@kolaf Thank you! :)

I update the download in the first post here, whenever I upload a new version.

Newest update 1 minute ago: Implementation of S_MULTIMETER!

Please let me know if this works for you.

I'm planning to add a battery channel for every sensor. So if a sensor is added via UI, you are able to select/deselect a channel you don't need it. In *.items you are free to define the channel too.

[kolaf]

Thanks, that was quick. However, something is not right:

@kolaf: Interesting. I'm not able to reproduce the error. Did you clean the userdata directory? OH2 gets stuck, when the xml-Definition changes, because it uses some sort of cache.

Because it is somewhat annoying to start from the scratch after deleting userdata, I define fixed things (like the gateway) in the *.things file.

[kolaf]

Thanks, it seems that that was the problem.

Hi everyone. Just to let you know OpenHAB 2.0.0 first BETA release is available. Unfortunatelly Tim0's binding is throwing some errors while OpenHAB tryes to install it.

kewl, thank 4 digging this up. I'm just evaluating openHab2 :D

[ofverstedt]

Hi Timo,

Regarding the errors in OH2beta, see this post for a possible solution.

Some other questions:
Is it possible to access sensors with different "V_types" for example V_VAR1 to a temperature sensor? I would like to send out numbers to my sensor nodes from rules.

I was not able to get the battery level to work.
my item looks like this:

Number SHBat "Storehouse Node Battery Level [%f %%]"       (nSH,gBAT) { channel="mysensors:temperature:gateway:SHtemp_in:battery" }

What is wrong?

Thank you for a great work!
