openLuup email server

[Buxton]

Hey AK, per the above about configuration options, it seems to me that a console page displaying every single topic that arrives at openLuup is the way to start the configuration process. Perhaps with a clickable sort option based on topic or prefix. I'm thinking of a checkbox to the left of a list of topics that allows one to subscribe, with the most current message displayed just underneath the topic syntax. So a two line notation for every topic. Then a second checkbox called purge for old obsolete topics that are no longer used (which would vanish on a luup reload).

A subscription table should eliminate hard coded prefixes in the Tasmota bridge as the bridge would create generic MQTT "devices" based on what topic name you subscribe to. From there, you can create sensors, switches etc based on what you want to pull from the MQTT device.

I downloaded the latest development version 21.4.25 and am now seeing the following behavior where the AltUi tags/category etc disappear from the device page:

Here is the same screen shot using the master branch 20.5.22. This was captured only minutes later when I downgraded to the master branch:

As well, I'm seeing receive errors again in the log for the MQTT connection to mosquitto. These errors were not present in 21.4.18 but an update to 21.4.25 shows them back with my Mosquitto connection flopping with each error..... is there any way I can revert to 21.4.18. I tried a couple of different syntax changes in the plugin update field, but I can't pull any development version except for the current one.

@akbooer As best as I can tell, the mqtt.incoming function is being sent nil values, so you go straight to the error handler because "client" is nil and therefore "message" is nil. Debug code below:

  local message, errmsg = MQTT_packet.receive (client)
  
  local sClient, sMessage, sCredentials, sSubscriptions = unpack(client), unpack(message), unpack(credentials), unpack(subscriptions)
  
  if sClient == nil then sClient = "nil" end
  if sMessage == nil then sMessage = "nil" end
  if sCredentials == nil then sCredentials = "nil" end
  if sSubscriptions == nil then sSubscriptions = "nil" end
  
    _log ( "client " .. sClient .. " message " .. sMessage .. " creds " .. sCredentials .. " subs ".. sSubscriptions)

Creates the following sample log message:

2021-04-25 18:51:22.332   luup.tasmota:262: Topic ignored : tele/power_BedroomTV/INFO2 : {"WebServerMode":"Admin","Hostname":"power_BedroomTV-4552","IPAddress":"10.17.2.28"}
2021-04-25 18:51:22.333   openLuup.mqtt:: client nil message nil creds nil subs nil

@buxton I can confirm the same problem. Om my test Pi running v21.4.25 (and AltUi 2.53c) the AltUi tags are missing and on my main server still running v21.4.18 the tags are there.

I do not however have any new Mqtt errors on the v21.4.25 server, but then I am not connecting to mosquitto either.

[akbooer]

OK, apologies to all. I obviously need to improve my pre-release testing in this area. I don’t use AltUI much these days, and it’s hard to automate tests. I’m not seeing any MQTT errors, either.

I will tag the earlier release so that you can revert. Will let you know when that’s done.

Sorry, again.

[akbooer]

@Buxton @ArcherS

OK. tagged release v21.4.18 should now be available.

[akbooer]

FWIW, I've now updated, and hopefully corrected, the code – v21.4.26 is the latest development version. So, I'd be very grateful if anyone is brave enough to test this.

I'm really glad of this error being highlighted, beause it's caused me to re-think somewhat the openLuup object API, and I'm rather happier with the outcome now. No guarantees, of course, that this fixes all the problems, but I hope that it is a step in the right direction.

PS: One of my systems exhibited the AltUI missing buttons, but, curiously, one did not. However, they both appear to work OK after this update.

@akbooer

Did you revert the chdev.lua file all the way to dec 2020 version? It seems to be a mistake but I wanted to check nevertheless...

[akbooer]

Yes, that's correct. It effectively rips out some recent changes which now don't fit with the roadmap forward.

I had previously been adding, partially hidden, features to the usual luup API. My plan now is to freeze the functionality of that API (which is what third-party plugins use, including AltUI) but to extend the underlying openLuup object-oriented API. In doing so, I hope to minimize the chance of breaking working plugins.

In this particular case, the changes have been to 'virtualize' device variables so that they can now be addressed directly as program variables, rather than having to resort to get/set functions. The Shelly and Tasmota bridges use this approach.

[Buxton]

@akbooer With .26, the sub-menu is back, and I don't see any errors outside of the MQTT receive error.

I wouldn't be overly concerned with "Development" branches breaking things. That's the risk users take with deploying those branches. I'm stoked on your MQTT advances and am more than willing to troubleshoot the inevitable bugs that pop up when building out new features....

[ArcherS]

@akbooer installed v21.4.26 on my test Pi and it seems to work.
The AltUi tags are back. The Shellies seem to work, also the Tasmota seem to update.
No errors in the log so far.

Is this ready for prime time? No biggy if not, yet

@catmanv2

I’m using it in my 'production' system. I’m not planning any major enhancements (indeed, there isn’t much more to add) and all the Shelly and Tasmota bridges need is support for more devices.

So it works for me (I don’t bridge to another MQTT server myself.)

[CatmanV2]

Thanks. Updated OpenLuup to 21.4.26 and the tags are back

Hi guys - just received some Shelly H & Ts. Is there any documentation on how to connect these to mqtt (in novice speak )? Have read the thread but am getting slightly confused - do I need just the openluup mqtt server or another plugin also?

[akbooer]

No other plug-in required… Shelly and Tasmota plugins are built-in. For Shellies, you just need to plug in the IP address of openLuup as the MQTT server.

[powisquare]

Will I need to set ports or do anything in Lua Startup still?

[akbooer]

@powisquare

Yes, you need simply to set up a port for the MQTT server

luup.attr_set ("openLuup.MQTT.Port", 1883)

In Lua Startup, and set the same for the Shellies.

[powisquare]

OMG. Genius. Many thanks indeed! Note to self - for Shelly .. Internet & Security/Advanced - Developer Settings/Enable MQTT
