openHAB 2.2 binding

[TimO]

@Nicklas-Starkel It happens, that MQTT support is sadly still on the to do list. There were some changes in the Smarthome MQTT library and we need to adopt them now.

Here's the Issue: https://github.com/tobof/openhab2-addons/issues/98

[Nicklas Starkel]

@TimO, cool that you are stil on it, even if it's on the "todo-list".
Kudos and keep up the great work :)

@TimO

Can we use this binding for MQTT once the PR is available in OpenHAB?
It is a separate mqtt generic binding in ESH for things discovery but I cannot make out if this will solve the dependency issue or not.

@TimO My sketches are sending the nodes remaining battery power to the controller via a V_VOLTAGE. Openhab 2 with your binding doesn't seem to be able to read these values. Is this an error (possibly on my side) or does the not yet support this?

[TimO]

@LastSamurai Did you connect a channel / item for V_VOLTAGE? If the sensor is not represented by the sketch you need to connect it manually.

[TimO]

@gahlawathome I'm currently looking into the new MQTT implementation in smartphone. It should work without the PR above. The PR will bring us a new option to connect a MQTT binding with OpenHAB!

[LastSamurai]

@TimO I am not sure what you mean.
My sketch sends a presentation:

 present(CHILD_ID_BATTERY, S_MULTIMETER);

and in openhab I added these (tried both sensor kinds)

// things
customSensor abc [nodeId=26, childId=1]
multimeter def [nodeId=17, childId=1]
// and items
Number 	voltageSensorWZ ... { channel="mysensors:multimeter:gwSerial:def:volt" }
//...

Is there anything i am missing here?

[TimO]

@LastSamurai

The channel is not correct:

channel="mysensors:multimeter:gwSerial:voltageSensorWZ:volt"

It's confusing, but that's the way OpenHAB2 handles channels. :confused:

[LastSamurai]

@TimO Thanks for your help though I am afraid you mixed something up there. The channel linking to the item itself doesn't really make sense ;)
Not 100% sure why it did not work earlier for me but I now got it to work like this:

// thing
multimeter		voltTHWohnzimmer	[nodeId=1, childId=2]
// item
Number 	voltageSensorWZ 		"Spannung [%3f mV]" 		<poweroutlet_eu> 	(grVolt, grWZ)	{ channel="mysensors:multimeter:gwSerial:voltTHWohnzimmer:volt" }

My error in the code above seems to have been that I defined most as customSensor instead of multimeter.

@LastSamurai

The channel is not correct:

channel="mysensors:multimeter:gwSerial:voltageSensorWZ:volt"

It's confusing, but that's the way OpenHAB2 handles channels. :confused:

Is the pattern:
<binding name>:<mysensors type>:<gateway id>:<thing name>:<data name> ?

[gerritv]

Just to let you know that I am very happy with this binding.
One thing for others to be aware of:
If you use PaperUI for configuring etc, make sure you leave Simple Mode off if you expect to use Groups later on. Simple mode adds the items (including the VAR1-5 :-() automatically but they are not 'managed'. This means you will get 404 and 405 errors on trying to edit them later on.
My solution was to let the binding autodiscover and add the Things. Then add 1 Item manually so that the \\192.168.0.123\openHAB-share\openhab2-userdata\jsondb\org.eclipse.smarthome.core.items.Item.json
file gets created and filled with an example to clone. I then added the various sensors using Name of pattern <binding name><sensorname><nodeid>_<dataname>, e.g. "mysensors_light_level_node4_last_update": { "class": "org.eclipse.smarthome.core.items.ManagedItemProvider$PersistedItem", "value": { "groupNames": [ "gLastUpdated" ], "itemType": "DateTime", "tags": [], "label": "Last", "category": "calendar" } },

You must stop Openhab before editing the file (else you will lose your edits) but once it starts up again you will see the Items listed in PaperUI (and VSCode if you use that). You can then add the Channel/Item links for each Thing.

Thanks for some great work @TimO ! Version 2.2 now works smoothly with my simple OpenHAB setup (2.2 snapshot).

One thing I noticed is that the gateway thing configuration page says "Disable network sanity check" even though the logic has been reversed in v2.2.
So the UI needs to be similarly changed to "Enable startup check" instead.

While I'm at it, could you please also clarify (in the UI) what "Send delay" is? Please also add that timing is in ms. If I understand things correctly it could say "Minimum time between messages sent to the gateway (ms)"

Also, the comment for "Imperial/Metric selection" could use some clarification. Preferably change the label to "Imperial units" and the explanation to "Use imperial units (default is metric)."

And finally it would be great to add add that the time is given in "...(minutes)" for the Network sanity check interval.

I have just updated to the stable openHAB 2.2 Version and everything seemed to be working just fine in the beginning but after the next restart I got this error:

10:31:19.727 [WARN ] [fig.xml.osgi.XmlDocumentBundleTracker] - The XML document '/ESH-INF/binding/binding.xml' in module 'org.openhab.binding.mysensors' could not be parsed: The XmlConfigDescriptionProvider must not be null!

It seems like I can still control my devices just fine but I just wanted to make sure that this doesn't cause errors down the line. So @TimO any idea where this error is coming from?

After upgrade OH to 2.2 stable release. (2.2_01). I'm having the same issue that zwave binding not working. After Mysensors binding is installed and gateway configured. There is only one serial port visiable in PaperUI, which is /dev/ttyUSB0 that is configured for the serial gateway. I'm using org.openhab.binding.mysensors-2.2.0-SNAPSHOT-serial-fix.jar.

Also the old 2.1 snapshot version doesn't work either. anyone else experience this issue?

[jocke4u]

Hi,

I have issues with MySensors and specifically Energy Sensors where they request latest value.
See this thread for details: https://forum.mysensors.org/topic/8833/power-sensors-stopped-working

Any idea how to solve it?

[lesockz]

Hello,

iam using "openHAB 2.2.0-1 (Release Build)" as openhabian on a PI3.

i've installed "org.openhab.binding.mysensors-2.2.0-SNAPSHOT.jar" as explained in the instructions.

configured the thing "MySensors Serial Gateway" to use "/dev/ttyACM0" with Baudrate "38400" because i'm using a pro micro with 8Mhz which isn't capable of 115200 (as far as i know).

the Items got discovered fine.

Atm i have only one item with

#define CHILD_ID_TEMP 0
unsigned long SLEEP_TIME = 3 * 1000; // Sleep time between reads (in milliseconds)

MyMessage tempMsg(CHILD_ID_TEMP, S_TEMP);

Presentation:

void presentation()
{
  // Send the sketch version information to the gateway and Controller
  sendSketchInfo("Temp/Hum/Pre Sensor", "1.2");

  // Register all sensors to gateway (they will be created as child devices)
  present(CHILD_ID_TEMP, S_TEMP);
}

and Loop:

  unsigned long currentTime = millis();
  temperature++;//bme.readTemperature();


    lastSend = currentTime;
    send(tempMsg.set(temperature, 2));
    lastTemp = temperature;


  sleep(SLEEP_TIME);

This is my debug from "openhab-cli showlogs"

So from log i can see Temp is counting up. but in "Paper Ui"

i always get "Temperature -NaN °C" or "Temperature 0 °C"

Please correct me if this is the wrong place for this question.

Up my own post. Not many users are using Zwave dongle and Mysensors at the same time? I feel this forum or trend is dead... This problem is driving me crazy, render all my mysensors useless. I'm trying to build a ethernet gateway now...

[TimO]

Hey @mythbai !

Could you please download and install the most recent version of the binding? I've not changed anything at the serial code, but while we're trying to figure out the problem, we should be on the same base of code. :-)

I too have two serial devices connected to my OpenHAB box, one serial MySensors gateway and one Ebus-Adapter to Ebusd.

You may need to execute:

feature:install esh-io-transport-mqtt

Because the most current version of the binding now supports MQTT gateways.

[TimO]

Hello @lesockz !

Well your node is sending V_RAIN instead of V_TEMP, so OpenHAB is not able to work with that.

Try:

MyMessage tempMsg(CHILD_ID_TEMP, V_TEMP);

For presentation S_TEMP (== 6) is used, while for set messages V_TEMP (==0) is used.

[TimO]

@mythbai While the code for the serial connection in the binding was unchanged for a while it definatly issn't working now together with zwave binding.

Some time ago I've prepared a change of the serial library the binding is using. A few first tests looked promising but I didn't find the time to test it. So lets give it a new try: could you please test this binding: OH2 Binding with Serial Refactoring

Please remove the old binding with bundle:list, bundle:remove ID before installing the new one.
