My final setup to get MySensors and OpenHab communicating via MQTT
-
@Martin-Tellblom
OK. I am not getting any from 'mygateway1-in/#'. Let me check.Just to be clear, in the above sketch
sendSketchInfo("Light Sensor", "1.0",true);
send(msg.set(lightLevel));
should have caused messages in 'mygateway1-in/#'?
Thanks,
@zuolan
Hi.That's correct, whats shown is the presentation and the last row the LightValue, MySensors/100/100/1/0/23
First of all I don't think there is any problem at all in your sensor sketch, the only thing I have changed in my is that I have changed is that I added this row:
#define MY_NODE_ID 100What I think the problem is that you are subscribing the wrong topic:
As I mentioned before my MQTT settings are:
// Set this nodes subscripe and publish topic prefix #define MY_MQTT_PUBLISH_TOPIC_PREFIX "MySensors" #define MY_MQTT_SUBSCRIBE_TOPIC_PREFIX "MySensors-out"Observerve that the MQTT topics is case sensative ie MySensors is NOT the same as mysensors.
I use MQTT-SPY (java based listener) to look at the messages and here you can look at every message sent when subscribing to # (And there is a BIG differense if you publish to MySensors or /MySensors). I suggest that you use MQTT-SPY and subscribe to both /# and # and that should catch all messages that comes to your broker (exept system messages)
Here you can se the differense between using the correct upper and lowercase and not. The first picture subribes to MySensors/#
And this one subscribes to mysensors/#

@Martin-Tellblom
Thanks again.I installed mqttspy and changed #define MY_NODE_ID 100.
I subscribe to the following topics:
mygateway1-in
/#I'm still not getting any messages in mygateway1-in.
Especially not this one: "MySensors/100/255/3/0/6 Light Sensor" that you are getting.
All the messages I can see still in mygateway1-out/255/255/3/0/3 topic.
So I think data from my Light Sensor node is not getting through.Your thoughts? And how to debug this?
On the COM port of the Light Sensor I got below. Do you see any indication showing it is sending data to mqtt? What about the !TSM:FALILURE?

I actually have the problem below solved. Since I already finished writing, so I am leaving this here for other people.
More information on this.
Although the Light Sensor data is not getting through, the Light Sensor node does cause all these MQTT messages to be sent.
Before I turn on the Light Sensor node, there is no MQTT message on the mqttspy and on the GatewayW5100MQTTClient COM port it is very quiet and I got this:
After I turn on the Light Sensor node the MQTT messages started comming and on the GatewayW5100MQTTClient COM port:

.......So question is why the messages from Light Sensor do not get through (or I am still not capturing them) while causing messages being sent on mygateway1-out/255/255/3/0/3?

Hi.That's correct, whats shown is the presentation and the last row the LightValue, MySensors/100/100/1/0/23
First of all I don't think there is any problem at all in your sensor sketch, the only thing I have changed in my is that I have changed is that I added this row:
#define MY_NODE_ID 100What I think the problem is that you are subscribing the wrong topic:

// Set this nodes subscripe and publish topic prefix #define MY_MQTT_PUBLISH_TOPIC_PREFIX "MySensors" #define MY_MQTT_SUBSCRIBE_TOPIC_PREFIX "MySensors-out"Observerve that the MQTT topics is case sensative ie MySensors is NOT the same as mysensors.
I use MQTT-SPY (java based listener) to look at the messages and here you can look at every message sent when subscribing to # (And there is a BIG differense if you publish to MySensors or /MySensors). I suggest that you use MQTT-SPY and subscribe to both /# and # and that should catch all messages that comes to your broker (exept system messages)
Here you can se the differense between using the correct upper and lowercase and not. The first picture subribes to MySensors/#
And this one subscribes to mysensors/#
@Martin-Tellblom
Your advice of changing the MY_NODE_ID made the difference. I foolishly left it in the MyConfig.h file so it is conflicting with the gateway.
So on mqttspy I now get this!!!!!!!!!!!!!!!!!!!!!!!!!!!
Thanks so much for helping me.
-
On the topic of editing header files, I found (maybe this is obvious for other people) many including the #define MY_SOFTSPI should be done in the sketch (before the corresponding header file is included?). In this way you don't have to worry about changing it back or conflict.

Thats good that you found the problem.

Thanks.
I now try to get MQTT to talk to openhab by following the RelayActuator example. I only have the openhab demo running.
I am not sure I have enough information in the above instruction to comple the mqtt.items file. For the following MQTT topics setup of mine,
I will try the following for the first line:
String Garage_Door "Garage Door [%s]" (gGarage, Windows) {mqtt="<[broker:mygateway1-out/102/1/1/0/2:state:MAP(1closed0open.map)]"}For the second line I am really stuck about how the do the "/2/2/0/0/2/"part:
Switch MQTTTestSwitch "MQTT Test Switch" (gBasement) {mqtt=">[broker:mygateway1-in/2/2/0/0/2:command:ON:1],>[broker:mygateway1-in/2/2/0/0/2:command:OFF:0]"}How should one figure out?
OK. To answer my own question the information is clearly here:
https://www.mysensors.org/download/serial_api_20#sensor-typesI will be reading up.

s distribution, i can't get openhab to distribute Address to the nodes when connecting, the MQTT Gateway sketch of my sensors doesn't do that right ?
Any tips that would be great
Set a static node id using
#define MY_NODE_ID 2020 in this case is the node id.

I wanted a solid platform to connect MySensors to OpenHab. I struggled getting messages to come back from OpenHab to MySensor with both the serial gateway and the MQTTGateway on 1.5.4. Finally I abandoned that approach and went to MySensors 2.0 MQTTClientGateway > Mosquito > OpenHab and it all works beautifully. I am posting my final setup so that maybe it will help others trying to accomplish the same thing. If I have omitted anything critical please reply and I will try to update this.
Controller
- Raspberry Pi (Jessie)
- Openhab 1.8
- make sure you org.openhab.binding.mqtt-1.8.1.jar in your addons directory
- 192.168.1.101
MQTT Broker
- Mosquito on same Raspberry Pi as OpenHab
- followed steps to install here https://mosquitto.org/2013/01/mosquitto-debian-repository/
- 192.168.1.101 running on port 1883 this needs to be set in both OpenHab.cfg and in GatewayW5100MQTTClient sketch (see below)
MQTT Client Gateway
- Genuine Arduino
- Gikfun Ethernet Shield W5100
- Addicore nRF24L01
- MySensors 2.0 https://github.com/mysensors/Arduino/archive/master.zip
- GatewayW5100MQTTClient from examples folder in zip
MySensors RelayActuator
- Arduino Nano clone
- Addicore nRF24L01
MQTT Client on my iPhone
- This is so useful for getting the messaging correct (both from OpenHab and Sensor)
- MQTT Inspector 1.0 is the one i used
GatewayW5100MQTTClient sketch I didn't change these lines but you need to note them. They form an important part of the message structure that your openhab items will need to subscribe to
// Set this nodes subscripe and publish topic prefix #define MY_MQTT_PUBLISH_TOPIC_PREFIX "mygateway1-out" #define MY_MQTT_SUBSCRIBE_TOPIC_PREFIX "mygateway1-in"It is important to change the lines below so that the MySensors MQTT Client device is on your network and can communicate correctly. Use the same subnet as your other devices. You can get gateway information using ipconfig on windows..
// Enable MY_IP_ADDRESS here if you want a static ip address (no DHCP) #define MY_IP_ADDRESS 192,168,1,87 // If using static ip you need to define Gateway and Subnet address as well #define MY_IP_GATEWAY_ADDRESS 192,168,1,1 #define MY_IP_SUBNET_ADDRESS 255,255,255,0Change these lines to point to your Mosquito MQTT Broker
// MQTT broker ip address or url. Define one or the other. //#define MY_CONTROLLER_URL_ADDRESS "m20.cloudmqtt.com" #define MY_CONTROLLER_IP_ADDRESS 192, 168, 1, 101 // The MQTT broker port to to open #define MY_PORT 1883openhab.cfg I probably should have called the broker mosquitto instead of mysensor but just note that this is the alias openhab will use to talk to the broker and can be anything you choose
# URL to the MQTT broker, e.g. tcp://localhost:1883 or ssl://localhost:8883 mqtt:mysensor.url=tcp://192.168.1.101:1883 # Optional. Client id (max 23 chars) to use when connecting to the broker. # If not provided a default one is generated. mqtt:mysensor.clientId=openhab1closed0open.map this is in opt/openhab/configurations/transform
1=closed 0=openmqtt.items
before each message is a symbol. < means openhab is subscribing to this topic. As such topics need to be prefixed with the values in your gateway. If you left the default use mygateway1-out prefix. I am not including the code I use to publish to the Garage Door item. > means openhab is publishing to this item. The default prefix here is mygateway1-in. Now the good news here is once everything gets connected and starts sending messages, you can use a MQTT client to watch for specifc messages by subscribing to both mygateway1-out/# and mygateway1-in/#. This is how i dialed in the values you see in my mqtt.items file.String Garage_Door "Garage Door [%s]" (gGarage, Windows) {mqtt="<[mysensor:mygateway1-out/101/3/1/0/16:state:MAP(1closed0open.map)]"} Switch MQTTTestSwitch "MQTT Test Switch" (gBasement) {mqtt=">[mysensor:mygateway1-in/2/2/0/0/2:command:ON:1],>[mysensor:mygateway1-in/2/2/0/0/2:command:OFF:0]"}Modified RelayActuator Sketch from MySensors 2.0 examples

For example, originally my Garage Door item was of type contact and i kept getting messages in my openhab.log that said it could not set state because new value was NULL. I switched it to string and it worked.
@Eric-Buhring I found that changing the line in the my sensors program that sends the message as below allowed me to use a Contact rather than a Switch
if (value != sentValue2) { // Value has changed from last transmission, send the updated value send(msg2.set(value==HIGH?"OPEN":"CLOSED")); sentValue2 = value; }
