Migrating MQTT1 items to MQTT2.4 items

[Sascha_Billian]

@kaju666

But can somebody help me what to add here or change to have my switch to know when it’s turned on by RF Pilot or the hardware button?

Sonoff will publish always the same state if is triggered. that means a MQTT command or pressing the button on the sonoff will always publish the same state.
So i am afraid there is no way to do it like this, but in OpenHab you could have a proxy item (= an item without channel) that then publishes a MQTT command to the sonoff. So if sonoff switches on without this item being set to on => somebody triggered the sonof remotely.
Otherwise sonoff is triggered by openhab:

Switch SonoffProxy

rule "Switch Sonoff from OH"
when
   item SonoffProxy changed from OFF to ON
then
  MyRealSonoffItem.sendCommand(ON)
  logInfo("sonoff rule", "sonoff triggered from OH")
end

So if I understand it right, there is no way (without using a proxy item) to reflect on an openHAB sitemap a change to an item that occurred when a physical button was pressed?
I mean, I want my Basic UI switch item to show as ON when my wife switched the light by using the light switch and not the app. Is that possible?
Thanks!

Problem Statement Often one will have certain cross cutting code that is used across .rules files by a diverse and varied collection of Rules. Such things can include things like calculating time of day to control the behavior of a rule, sending alerts, calculating state to drive a state machine, etc. For example, Lighting, blind/rollershutter controls and HVAC may all…

[Q] So in new MQTT 2.4 there is no possibility to configure it using files. The paperUI and adding through Things is the only way?

[opus (Jürgen Baginski)]

[A] Wrong. Search the forum, I have posted several examples on how to configure MQTT2 with files.

@Sascha_Billian @alexspitz This configuraion knows when the hardware button or rf button was pressed and change state in basicui.

Using Sonoff Power Switches with Tasmota firmware and openHAB2 MQTT2 binding

Hi guys, after hours of working on my openHAB2 configuration for my Sonoff Smart Switches, using the Tasmota firmware, I got that running, using the new MQTT2 binding. As for now I have 7 Sonoff Power Switches and didn’t want to configure them through PaperUI. After a hint from @Dim I got my configuration completely in files, providing me with the ability to do some slight changes on all channels at the same time. This is just meant as an example and I would be more than happy, get more hints …

This is now my working settings

Thanks @kaju666
Are these working settings or do you still have problems?

[kaju666]

For now it works like a charm

[vzorglub (Vincent Regaud)]

Cool then could you change your post above to:
“This is now my working settings”

Thanks

I am working on migrating my MQTT1 items to MQTT2.4 and it is going pretty well .

Nevertheless, I am stuck migrating some items that required a JS transform call like this

String Location_Den_Samsung "Owntracks Location Den Samsung [%s]" <mqtticon> {mqtt="&lt;[mymosquitto2:owntracks/denis/samsung:state:JS(mqttitude-coordinates.js)]"}

So when I enter

JS(mqttitude-coordinates.js)

in the Incoming value transformation field of the Configure Channel form in Paper UI I always get an error on my Generic MQTT Thing that says

Status: OFFLINE - CONFIGURATION_ERROR Remove and recreate: mqtt:topic:ff8e91b4:Test

What should I write there ?

[vzorglub (Vincent Regaud)]

@Denis_Lambert

JS(mqttitude-coordinates.js)

You should write:
JS:mqttitude-coordinates.js

[Denis_Lambert]

Yes ! Thank so much for the hint! All my MQTT migration is now done and working very well.

[seth_amit (Amit Seth)]

I am SUPER new to this and with very little tech background.
Was struggling with codes and such; searching for conig files ( I am on OpenHAB 2.4 LOL)
Your post sorted it out for me;Sonoff Tasmota running like it should…a Charm!

getting this error with my setup not sure whats wrong it reading but not getting temp in

[vzorglub (Vincent Regaud)]

JSONPATH:$.DS18B20.Temperature

thanks for that another typo from me been trying for 2 days to get that working

@Sascha_Billian

Switch Sonoff4CH_Garden_Left_Relay1 “Relais 1” <poweroutlet> {mqtt=“>mosquitto:cmnd/Home/Garden/Sonoff/Left/power1:command:*:default], <[mosquitto:stat/Home/Garden/Sonoff/Left/POWER1:state:default]”}

@Sascha_Billian Not like it matters but there should be an opening square bracket [ after the > and before mosquitto I think. I tried to compare your before and after items entry with mine and spotted that little difference.

[Sascha_Billian]

Thanks. Must have been only a typo since my MQTT on OH 2.3 was running without any issues.
Anyway i’ve corrected it

[Andreas_Beistle]

Hi there, i am trying to Setup my new Installation with mqtt2.4, till now i just used the old one with textual config and worked fine. I used map Transformation to transform 1 to on and 0 to off on the Incoming value and now i dont know how to do this in paper ui. is it even possible?

Always get the following error:
Command '0' not supported by type 'OnOffValue': No enum constant org.eclipse.smarthome.core.library.types.OnOffType.0

Thanks in andvantage

Hi!

Do I need to install the “MQTT Embedded Broker” via Misc in Paper UI or is it enough to install only the mqtt binding posted in first thread?
