MySensors: trying to add Things in WebThings Gateway

[alowhum]

Thank you for the logs.

Perhaps this is a point where it crashes and reboots the add-on:

2019-06-19 15:33:27.935 ERROR : mysensors: DEBUG:mysensors:Sending 1;255;3;0;19;
2019-06-19 15:33:29.635 INFO : About to call startPairing on MySensorsAdapter

I also noticed that it keeps re-requesting the presentation of your nodes:

2019-06-19 15:33:34.617 ERROR : mysensors: INFO:mysensors:Requesting new presentation for node 2

This could mean:

• You have created a node that somehow has the same node-ID as an earlier but different node. Although in theory the add-on handles this case now.
• Some data is missing that is required to actually create the device. This could be the name.

Can you share the Arduino Code? Could it be that your presentation function does not send names? Your presentation should look something like this:

sendSketchInfo(F("Sensor name"), F("1.1"));
present(CHILD_ID, S_BINARY, F("Button name"));

Here's another example sketch:
https://forum.mysensors.org/topic/10342/mozilla-webthings-mysensors-add-on-adapter/14

// By the way, I don't think using v2.2 should matter. Internally the PyMySensors library actually uses 2.2.

[rmalbers]

I need to keep better track of what software is running on a given cpu/sensor, sorry about that but I didn't think of it at the time! I 'think' this is what is running on the office sensor. I should probably build a new sensor using this code and make sure it works the same, (log files match what I've been giving you):
// Enable debug prints to serial monitor
//#define MY_DEBUG

// Enable and select radio type attached
#include <MyConfig.h>

#define MY_RADIO_NRF24

//#define MY_RADIO_RFM69

#include <SPI.h>
#include <MySensors.h>
#include <DallasTemperature.h>
#include <OneWire.h>

#define COMPARE_TEMP 1 // Send temperature only if changed? 1 = Yes 0 = No

#define ONE_WIRE_BUS 3 // Pin where dallase sensor is connected
#define MAX_ATTACHED_DS18B20 16
unsigned long SLEEP_TIME = 30000; // Sleep time between reads (in milliseconds)
OneWire oneWire(ONE_WIRE_BUS); // Setup a oneWire instance to communicate with any OneWire devices (not just Maxim/Dallas temperature ICs)
DallasTemperature sensors(&oneWire); // Pass the oneWire reference to Dallas Temperature.
float lastTemperature[MAX_ATTACHED_DS18B20];
int numSensors = 0;
bool receivedConfig = false;
bool metric = true;
// Initialize temperature message
MyMessage msg(0, V_TEMP);

void before()
{
// Startup up the OneWire library
sensors.begin();
}

void setup()
{
// requestTemperatures() will not block current thread
sensors.setWaitForConversion(false);
}

void presentation() {
// Send the sketch version information to the gateway and Controller
sendSketchInfo("Temperature Sensor", "1.1");

// Fetch the number of attached temperature sensors  
numSensors = sensors.getDeviceCount();

// Present all sensors to controller
for (int i = 0; i<numSensors && i<MAX_ATTACHED_DS18B20; i++) {
	present(i, S_TEMP);
}

}

void loop()
{
// Fetch temperatures from Dallas sensors
sensors.requestTemperatures();

// query conversion time and sleep until conversion completed
int16_t conversionTime = sensors.millisToWaitForConversion(sensors.getResolution());
// sleep() call can be replaced by wait() call if node need to process incoming messages (or if node is repeater)
sleep(conversionTime);

// Read temperatures and send them to controller 
for (int i = 0; i<numSensors && i<MAX_ATTACHED_DS18B20; i++) {

	// Fetch and round temperature to one decimal
	float temperature = static_cast<float>(static_cast<int>((getControllerConfig().isMetric ? sensors.getTempCByIndex(i) : sensors.getTempFByIndex(i)) * 10.)) / 10.;

	// Only send data if temperature has changed and no error

#if COMPARE_TEMP == 1
if (lastTemperature[i] != temperature && temperature != -127.00 && temperature != 85.00) {
#else
if (temperature != -127.00 && temperature != 85.00) {
#endif

		// Send in the new temperature
		send(msg.setSensor(i).set(temperature, 1));
		// Save new temperatures for next compare
		lastTemperature[i] = temperature;
	}
	}
sleep(SLEEP_TIME);
}

When you create a new post, click on the 'code' button when you want to insert code.

Back on topic, I don't think that's the actual code, since the log showed that no sketch name was sent. Receiving the sketch name is what triggers the creation of the thing, so it's kind of important.

For example, here's a node presentation from my own logs:

2019-06-20 10:20:03.441 ERROR  : mysensors: DEBUG:mysensors:Receiving 33;255;3;0;11;Fireplace
2019-06-20 10:20:03.446 ERROR  : mysensors: DEBUG:mysensors:Receiving 33;255;3;0;12;1.2

...Yet I don't see "Temperature Sensor" anywhere in your logs.

Also in your errors I can see this strange situation where the add-on keeps requesting node 0 to present itself.

2019-06-19 15:34:00.801 ERROR : mysensors: DEBUG:mysensors:Sending 0;255;3;0;2;
2019-06-19 15:34:00.875 ERROR : mysensors: DEBUG:mysensors:Receiving 0;255;3;0;2;2.2.0

Node 0 should theoretically be the MySensors gateway. It only responds with it's version, and not a name. Perhaps that's also an issue (although theoretically it shouldn't be, since node 0 is never turned into a thing).

Come to think of it, I don't see any messages being handled by the add-on other than the initial two messages from the Gateway.

You should see all kinds of things with >> like:

2019-06-20 10:30:34.498 INFO   : mysensors: << Requesting presentation from 35
2019-06-20 10:30:34.500 INFO   : mysensors: >> incoming message > presentation > id: 35; child: 255; subtype: 17; payload: 2.3.1

Ok, I'll look at this and probably just start rebuilding my sensor's and gateway making sure I get those names in there. When I built this over a year ago I was playing with different boards and different sensors and once I got things working in Domoticz I moved on. That's why I have so much program source code out there. This time I'll put a unique, my version number in there so I can keep better track. I think I'll even physically label the sensors this time! Thanks for all your time on this, I really like the looks of the WebThings GW and it's really a good fit for the stuff I'm doing/trying to do. Oh, thanks for that about the code button, didn't know about that.

[alowhum]

@rmalbers Wait one second. I've been playing with the code and I have a suspicion about what's going on. I'm uploading a new version of the add-on, try that first.

[rmalbers]

@alowhum Wow, ok, that's sounds great. I'll watch here for word.

[alowhum]

Version 0.1.0 has been accepted. Try it and let me know how it goes?

[rmalbers]

Ok ,updated addon and rebooted GW. This test was in Ethernet mode. No luck but the log sure looks different:

[alowhum]

Very strange.

I notice you press the pairing button immediately. You don't have to press the pairing button for it to scan for devices. But it shouldn't affect things either.

The only device in your persistence file seems to be your gateway (which it does not turn into a thing, but maybe it should. But that's another matter.)

Have you restarted your devices after starting the gateway? Otherwise they won't show up. Also make sure your devices send actual values when they boot or shortly after, otherwise those won't show up as properties.

I think it's time to have a look at your Arduino code.

[rmalbers]

BTW: I know I have to rebuild my sensors, but at least now I have 'things' sort of working and can see better what's going on.

[alowhum]

Oh my god :-D

[rmalbers]

@alowhum I guess I should sum it up: I have V2.2 and V2.3 sensors running using the Ethernet GW addon config and using the MySensors original, not rebuilt gateway, so the MS gateway is running unchanged, yet does work with the addon and WebThings GW. (I do have to rebuild sensors again for the 'imperial' config setting. domoticz didn't care but it looks like the WebThings GW does use it. (I have mixtures of F degrees, C degrees, etc.)

[alowhum]

I've updated the first post of the Gateway Addon thread to indicate that devices must be restarted to initially connect them.
