Help me with a Smart Home Interview – US Participants Needed

@akbooer I hate to add more to the pile... but I'm still seeing a receive error for the connection to mosquitto. openLuup 2021.04.29b

Here's the log error:

2021-05-01 14:22:38.815   openLuup.io.server:: MQTT:1882 connection closed  tcp{client}: 0x5579919e9c58

using the below error trapping in function "MQTTservlet"

	if client == nil then
	  _log ("client is in ERROR nil")
	else
	  	if table.concat(client) == "" then

	   _log (table.concat {"MQTT ERROR: ", table.concat(client)})

		else
	    _log (table.concat {"MQTT ERROR: ", table.concat(subscriptions)})
	    end
	end
	
    return function () incoming (client, credentials, subscriptions) end
  end

I can't find a deeper layer in the stack where I can trap for the incoming message to see what's in the message that is throwing the error. As near as I can tell, if openLuup tries to connect to a running mosquitto instance, then it fails to see the topics and messages, and passes empty--but not nil--strings when the servlet interface sees incoming bytes.

If I restart mosquitto, openLuup then sees the topics and messages and the error messages stop--and the connection to mosquitto remains stable.

This behavior does not occur when I aim an IOT device directly at openLuup--in that the connection to the device always resumes when openLuup reloads--in other words, I don't need to restart the IOT device to enable the connection.

@christian_fabre

I simply cannot reproduce this error, so can I ask you to try it again after having added this line to openLuup Startup (which enables debog logging for the MQTT server):

luup.attr_set ("openLuup.MQTT.DEBUG", true)

That may give a little more to go on.

I've have tried everything I can think of, deleting the Shelly plugin, and reproducing the announce message from your device. It all works just fine.

[christian_fabre]

I added "luup.attr_set (" openLuup.MQTT.DEBUG ", true)"
and I did a RELOAD

Just what I needed to see, thanks, I’ll work on it.

[akbooer]

I’m speechless. No explanation.

[christian_fabre]

ok thanks for trying to solve my problem.
in the near future i will try to reinstall OpenLuup on my Raspbery, maybe this will fix this problem.
Sorry for taking your precious time

[akbooer]

I haven’t given up. I can only think that, somehow, we are not running the same version of the code. You did confirm that your last install was, in fact, v21.5.2?

[Elcid]

Is @christian_fabre bridged to mosquitto? As when I reload OpenLuup I have to restart mosquitto to get them talking again.

[christian_fabre]

[therealdb]

@akbooer I will probably add more log, to see the exact payload sent. Sometimes those things are generating strange telemetry data, so maybe that's the case. I'll probably log what's going on around hadevice property as well. I was unable to re-produce it in my own install, so it should be something related to this particular model and its messages.

[akbooer]

@christian_fabre

If you are still interested, testing v21.5.3 is available. I have made considerable changes.

[christian_fabre]

I just installed the testing version 21.5.3.
It works great for Shelly but also for Tasmota

Merci bien

[akbooer]

@christian_fabre said in MQTT – setup and use:

Merci bien

Je vous en pris.

Believe me... I'm happy. So sorry for all the mis-steps, but I learned a few things along the way, so it was a worthwhile exercise!

[rafale77]

@akbooer

Now that you got that figured out, one awesome thing which could be done would be integrate this:

GitHub - Koenkk/zigbee2mqtt: Zigbee 🐝 to MQTT bridge 🌉, get rid of your proprietary Zigbee bridges 🔨

Zigbee 🐝 to MQTT bridge 🌉, get rid of your proprietary Zigbee bridges 🔨 - Koenkk/zigbee2mqtt

By creating a bridge supporting it on openLuup. It would enable me to move zigbee from home assistant to run directly to openLuup and I would likely take advantage of it to get rid of my hue hub as well, running a single zigbee network through mqtt...

[therealdb]

@rafale77 its topics are pretty organized, so it should be easy to do. The only difficult part is to get a reliable trace of messages, so an emulator could be written to facilitate development and testing.

[akbooer]

@buxton said in MQTT – setup and use:

As near as I can tell, if openLuup tries to connect to a running mosquitto instance, then it fails to see the topics and messages, and passes empty--but not nil--strings when the servlet interface sees incoming bytes.

OK, I’m ready to take a look at this. However the above statement makes no sense to me, since the server never connects to anything (because it’s a server – clients connect to it.)

[Buxton]

@akbooer Yes, that was poorly worded as it makes it sound like openLuup initiates the connection to Mosquitto.

The symptoms of the problem are that:

• if luup reloads, an occasional message that is sent to openLuup from Mosquitto causes a receive error in openLuup. It is unknown what that/those message(s) are.
• if mosquitto reloads, the openLuup error messages stop, so something changes in the way that openLuup sees the mosquitto data.
• this behavior does not occur with IOT devices.

A possible way to trouble shoot this is to place debug code at the incoming interface that will trap and display packets headed to the MQTT port. By comparing incoming timestamps with the error message timestamp, I should be able to tell what message is causing the receive error message--even though the message variable is empty at the time it causes the luup error. What is odd to me is that there is a lot of error trapping for bad messages in your code, but this message(s) seems to bypass all of that and arrives at the incoming routine empty.....

[akbooer]

I think we are being misled by your error messages. These tables are not empty...

local x = {a = 1, b = 2}
local y = table.concat (x)
print (y == '')

yields the expected result true.
