openHAB 2.0 binding

@Dave-Dan said:

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???

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.

@TimO said:

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.

+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.

@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.

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.

Thanks, regards.

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!

/Tomas

[TimO]

Hi Tomas!

Thanks for the hint, I will take a closer look!

@ofverstedt said:

This is currently not possible, but it will be. It is on my ToDo list. :-)
The current solution with the serial binding in OH 1.X is complicated, but leaves a lot of freedom for the user and I would like to preserve as much freedom as possible.

I've implemented some new features a while ago, like resending of messages if no ACK is received. But the Repo is out of date. I will fix that.

[gonzalonal]

Hi Tim0.
Really nice work with this binding. Huge step forward into a official MySensors OpenHAB binding.

It would be nice to have the repo updated so as to try the new features you have implemented.

Have you had time to check why we are gewtting that error at OpenHAB 2 Beta while trying to install the binding?

Let me know if there is any way in which I can help.
Thanks, regards!

Gonzalo.

Hi @gonzalonal !

I'm working on it. Due to the changes in the OH git repository my environment is all messed up. :-(

[andreacioni]

This kind of problem (as I've read online) in this release of OH seems to be not only related to this binding. One suggestion that I found is here: https://github.com/openhab/openhab-distro/issues/82 (last comment) or here: https://github.com/openhab/openhab-distro/issues/81

I've tested it without success but I don't know if I've done it right. I've also try to build myself a rfxcom binding (this one use gnu.io) and it has the same issue

hope this help

EDIT: this work for me, run on OSGI console: feature:install openhab-transport-serial and restart OH

Hi @andreacioni.

You saved the day. It worked for me.
Here the steps I did to make it work.

1- Download latest snapshot from https://openhab.ci.cloudbees.com/job/openHAB-Distribution/ (Download offline version)
2- Unzip the file.
3- Run start_debug.sh
4- In console write "feature:install openhab-runtime-compat1x"
5- Ctrl-D to exit/shutdown OpenHAB
6- Once exited, copy MySensors binding to addons folder.
7- Start againg OpenHAB-
8- Thats it. It should work

Remember to copy your serial thing to things folder.
Regards!
Gonzalo

[TimO]

@andreacioni: Absolultly amazing! Thanks!

I don't understand why this helps though because the changes in the code I have to do have nothing to do with OH1 (compability).

I hope to provide an adjusted version today or tomorrow along with a clean and working repository.

Thanks for your patience! :-)
