Hi,

I have this simple rule to test data tx to a node:

rule "Test"
when
        Item Test_Btn changed
then
        sendCommand(Test_Btn, "30;200;1;0;3;ON")
end

and Test_Btn is defined as the following item:

Switch 		Test_Btn  "Test Btn"

When I press the button, I get the following error:

18:18:34.161 [INFO ] [smarthome.event.ItemCommandEvent    ] - Item 'Test_Btn' received command OFF
18:18:34.182 [INFO ] [marthome.event.ItemStateChangedEvent] - Test_Btn changed from ON to OFF
18:18:34.199 [ERROR] [.script.engine.ScriptExecutionThread] - Rule 'Test': The argument 'command' must not be null or empty.

What does "The argument 'command' must not be null or empty" mean?

Hi,

I'm having trouble with the motion sample code. I have changed the setSleepHours(1) command to setSleepMinutes(1). I understand that the sensor will send a hart beat every 1 min. This is working fine for the hart beat, but evertime the hart beat is send the sensor sends a Trigger messages as well even though the sensor is not triggered. I thought that maybe there is a power dip and that it might cause the PIR (RS501) to send a interrupt, but I have removed the setSleepMinutes command and replaced it with a setBatteryReportHours(1) command. This command is send correctly and the sensor only sends the trigger command when the PIR is triggered. Did anyone have a similar issue?

Attached is the sensor debug output when the setSleepMinutes command is used:

Hi,
I have started to play with nodemanager and I have registered a SENSOR_DS18B20. Nodemanager handles all the heavy lifting and the sensor is reporting the temperature 100%. I can change the sleep and report intervals with “setReportIntervalSeconds and setSleepSeconds”.

Question 1:
According to the MySensors documentation (https://www.mysensors.org/download/serial_api_20#variable-types) a S_TEMP sensor can report the V_TEMP value and a V_ID value. Nodemanager populates the V_TEMP variable, but how can I populate and send the V_ID value?
Question2:
If I want to add an additional sensor I must register it with “registerSensor” and I would set the report interval for this sensor by getting a pointer to this sensor with “getSensor”, but how do I add custom code for this sensor in Loop()? How do I ensure that the custom code is only executed for this sensor and not for the other sensor?

Hi,

I have RF24 nodes which communicates to openHab via a Ehternet Gayeway. I have setup MQTT inorder to send configuration data to my controllers. I have used this openhab website to setup the MQTT. According to the website:
In addition to configuring MQTT publish/subscribe options for specific openHAB items, you can also define a generic configuration in the services/mqtt-eventbus.cfg file which will act on ALL status updates or commands on the openHAB event bus.

I have a "systeminfo" thing defined and everytime the the CPU load changes, OpenHab send all my sensor data via the MQTT topic.
So my question is:

1. Is it possible to reduce the number of data send via the MQTT eventbus? According to the webside it does not seem to be possible.
2. If no mqtt client is subscribed to the topic, will the MQTT broker (Mosquitto) still sent all the data?

@stefaanv I have installed MQTT-Spy and I can publish on the "openHAB/in/test_text/command" topic and OpenHub does forward the message to my node ,but I receive the reply data in the "openHAB/out/test_text/state" topic. Besides the expected data is there also a lot of other data from my other sensors as well. I have changed my mqtt-eventbus.cfg to :

broker=mosquitto
statePublishTopic=openHAB/out/test_text/state
stateSubscribeTopic=openHAB/in/test_text/state
commandSubscribeTopic=openHAB/in/${item}/command

I have hoped that it will limit the amount of data. This did helped a bit, but see all the additional data below. I receive this data even if the sensor is switched off. The debouncePeriod->0 ,timeBeforeSleep->0 and pulseCounter->0 is only received when I transmit the command via MQTT-SPY but the set is repeated every second.

Any idea how I can stop this data from being transmitted via mqtt?

@stefaanv Thank you for this detailed feedback.
I will try your suggestions this afternoon.

@stefaanv I like your method of sending config data to a sensor. I have tried your example but I don't receive any data on my sensor. Will you please clarify the following:

1. You gave and example of the mqtt.cfg configuration file:

mosquitto.url=tcp://localhost:1883
mosquitto.clientId=openhab
mosquitto.retain=true
mosquitto.async=false

What does the "mosquitto.clientId=openhab" mean? Is the "openhab" a name that I should have used somewhere in my OpenHab setup?

1. Your mqtt-eventbus.cfg example:

broker=mosquitto
statePublishTopic=openHAB/out/${item}/state
stateSubscribeTopic=openHAB/in/${item}/state
commandSubscribeTopic=openHAB/in/${item}/command

• Is the "broker =mosquitto" a name that I should have defined somewhere?
• Later on in your example you mention "The feedback is provided on topic=openHAB/out/test_text/command ..." but the "openHAB/out/test_text/command" is not indicated in the mqtt-eventbus.cfg file. Is that correct?

1. I have installed the latest OpenHab and I use the PaperUI to configure my Things. The PaperUI has detected my sensor as "mysensors:text:gateway:text_1_202:text" and I don't know where I can edit the name of the Thing. I have added the item in .items config file as

String test_text "text" <text> {channel="mysensors:text:gateway:text_1_202:text"}

1. I have installed mosquitto and I can subscribe and publish with the following commands:
   In one terminal I subscribe with

mosquitto_sub -h 127.0.0.1 -i openhab -t openHAB/in/text_1_202/command

and in another terminal I publish using:

mosquitto_pub -h 127.0.0.1 -i openhab -t openHAB/in/test_1_202/command -m info=

On the "subscribe" terminal I do get the "info=" message, but I don't receive anything on the node.
I'm not sure if my publish channel is correct because my node name is different than yours.

How can I check that OpenHab do receive the MQTT command?
Can you spot any other setup issue that I might have?

Thank you

Hi,

I have a sensor node communicating via RF24 to a Raspberry Pi (RPi) gateway. This RPi gateway is connected via Ethernet to Openhub ( the controller software) also running on the same RPi. This is all working fine. I want to add a SonOff relay to this setup and I want to communicate with the SunOff via MQTT messages.

If I install the MQTT broker software (Mosquitto) on the RPi, will Openhab be able to communicate with the SunOff device, or do I have to add another MQTT gateway application on the RPi?

@mfalkvidd Thank you. This will help a lot
