openHAB 2.0 binding

gonzalonal

Hi @TimO . Good we got in the same page.

I think this topic needs some more thinking.

I was reading OH wiki and found this about receivedCommand.


 Implicit Variables inside the Execution Block

Besides the implicitly available variables for items and commands/states (see the script documentation), rules can have additional pre-defined variables, depending on their triggers:


* Every rule that has at least one command event trigger, will have the variable 
receivedCommand available, which can be used inside the execution block.

* Every rule that has at least one status change event trigger, will have the variable
previousState available, which can be used inside the execution block.

https://github.com/openhab/openhab/wiki/Rules

Maybe this is not available anymore, or at least on OH2.

For now, I think it would be a better approach to use postUpdate at systemStart to populate the binding memory. With this, we'll avoid sending commands to the nodes.

Regards!

Hi again @TimO .

Just an idea.

What do you think about solving this problematic in this way:

We create a group whose members are all those items that later will populate the binding's memory. I have a group named mysqlpersisted where I put all the items whose data will be stored in my SQL DB. So I could use that group. For this example, let's call it "MemoryGroup"

Then, we can create the following rule:

rule "Populate MySensors binding memory"

when 
System started
then

(maybe add a delay to allow persistance services to load)

MemoryGroup?.members.forEach[i |
        postUpdate(i.name, i.previousState(true))
]

Using this method, memory would get populated everytime OH boots up, with data belonging to the persistance service that we use. And we use postUpdate, so no command is sent to the nodes.

With this I think we solve both problems as data in the binding will be concurrent with the persistance service data.

Let me know what you think about this.

Regards!

TimO

Hi @gonzalonal !

I was thinking in the same direction and I have played a litte bit with different rules. I had no success in finding a rule that worked. Additionally I don't like the workaround. ;-)

A good solution would be, to trigger a rule, if a request is received, but there too I had no success till now.

I'm still struggling with it ...

@TimO Do you think it would be hard to add MQTT support to the binding? I had a brief look to your code and it looks like the protocols are nicely isolated.

TimO

I'm currently trying to migrate my production environment from OH1 to OH2. I'm now using two serial gateways.

@kolaf : The problem you described occured to me too. In my case I use two serial gateways. I've added a little method that ensures that a connection to more than two serial ports via nrjavaserial is possible. It works within the OH2 binding. Could you test if it works with the RFXCOM binding you are using? A new jar is available on github. OH2 is currently using an old version of nrserialjava that has a bug. I don't know how to switch the version yet.

@tomkxy : I will integrate MQTT in my OH2 Installation soon and will come back to your request after that.

The binding doesn't seem to handle the "requestTime" function yet. Time-aware sensors would be able to handle temporary OpenHAB outages by executing some scheduled actions autonomously, which I could use in the window cover controllers I'm developing.

@TimO Thanks for the update. Unfortunately it did not seem to change anything for me, rfxcom still fails trying to use the wrong lock file. If it is helpful I can send you the log. Appreciate your input and effort.

kolaf

The weird thing is that it seems to work with an older version of OH2 (and an old version of your binding), but not with the more recent beta releases.

TimO

@kolaf : My guess is, the implementation in the could be the problem. Please do a litte test: remove the mysensors.jar file from the addons folder. Start OH2. RFXCOM should start fine now. Copy the mysensors.jar in the addons folder. OH2 will try to load the binding. What is the result?

I suppose this way both binding work fine together?!

kolaf

@TimO I tried this before, and removing the MySensors binding made the rfxcom binding work. However, this was not the case this time. I will try a bit later to also remove the zwave binding.

It appears that I get these errors even if I remove all the offending bindings. I think I need to start with a completely clean installation and see how it goes. I will let you know.

kolaf

Success, I think.

I started a brand-new installation of the latest OH2 snapshot, and sequentially added the rfxcom, z-wave, and mysensors bindings. After fiddling a bit with getting serial ports recognised by OH2 and getting the permissions correct, it seems to work. I still get some weird error messages, but apparently the library is able to work through its issues :-). An example of what I mean is included.

Returns out that I am still seeing the problem sometimes. If I change the configuration so that the bindings are reloaded (especially the zwav binding) it fails to reconnect to the serial port. I found someone who had posted an updated serial binding which supposedly solved some related problem (I think), but I'm not sure. It does not appear to have had any effect on the problem.

The modified version is available from one of the last posts here: https://github.com/openhab/openhab2-addons/issues/671

I managed to get things working pretty well under Linux, but I have now switched to a Windows-based installation to see how that is.

Currently I have all three bindings working at the same time using three different serial ports. This is finally allowed me to pay attention to what the mysensors binding is doing.

The seems to be some kind of delay through the system for messages coming from the device. This is quite evident from the log included below. Device number three is a power sensor which transmits about once a minute. For some reason things are bunched together. I guess some of these could be Retransmissions, though. The sensor is located 4 m away from the gateway. Number 10 is a temperature sensor in the basement.

For some reason I have had severe problems getting the sensor to talk to the Gateway today. It shouldn't be related to the binding, I know, but I'm loosing my mind trying to keep track of all the different factors here.

@kolaf : I'm glad the bindings are now working together.

The delay in the transmission is a bit strange. I've no idea where that could come from.
I've ported my production environment to OH2 and this didn't occure to me yet. I've upgraded a lot of my sensors to 2.0-beta and therefore took a closer look at the debug output of the OH2 binding to check if the devices present themself correctly and send the messages. I'll will keep an eye on it!

Currently I'm running OH2 with:

Astro1
Weather1
MySensors2
MySQL Persistence
Sonos2

In the MySensors network I have a couple of Sensebender Micros, a shutter control with 12 SSR and two nodes to control LED lights plus selfmade DHT22 nodes connected to two gateways (one serial, one ethernet (iboard)).

I'm glad it runs stable for days now, although it is obvious in some places that this is a beta release of OH2. There are icons missing and there are bugs in the basicui and the documentation could be much better.

Hi @Francois ,

thanks for report. Seems that the you are using 2.0 version of MS Gateway. If you do not need it for particular task, try install the 1.5 version. I'll try to fix your problem as soon as possible!

Francois

@andreacioni Thanks for this all my sensor are running on version 2 so I don't know it my nodes will run on an 1.5 serial GW

TimO

I have a serial and ethernet gateway with version 2.0 running without any problems.
In your case there are a lot messages arriving within a short time, maybe that is the reason the gateway won't react on the I_VERSION message from the binding.

Please disable debugging in the gateway and try again. The reliability of my gateway improved a lot after disabling debugging.

Francois

@TimO I still get the same error after I disable debugging in the gateway
