Are you on OH 2.4 or 2.5 snapshot? Because there was a bug in OH 2.4 that sometimes the action cannot be resolved correctly.

(J Wee) #62

I was on 2.5 snapshot, but is now on OH 2.4. is there a mqtt 2.5 snapshot that I can drop into the addon folder?

(David Graeff) #63

The action part is not in the mqtt binding but part of the openHAB core. So you really need to be on OH 2.5 for that fix. At the moment I recommend 2.5 anyway for mqtt and there are no breaking changes in bindings yet as far as i know.

(J Wee) #64

OK. looks like I have no choice. Lucky my OH is a docker installation.

Thank you David. I hope to have good news when I revert

Just did a new docker installation with 2.5 snapshot. got these errors

[error] [core.karaf.internal.FeatureInstaller] - Failed installing 'openhab-action-nma, openhab-action-mqtt,openhab-binding-mqtt1

Strange as I did not enable installation of mqtt 1 binding

(David Graeff) #65

Do you have an addon.cfg, check for “mqtt1” in there. Next: Check Paper UI or the openhab console for those bundles.

(Jürgen Baginski) #66

In my case the mqtt1 remained (after upgrade to 2.4) in the file

  • /var/lib/openhab2/config/org/openhab/addons.config

Stopping openhab, removing that file and restarting solved my problem with that entry!

(J Wee) #67

Thanks Jurgen. I will definately try that.
What would be the path for the addons.config if my OH is a docker installation?

(Scott Karns) #68

Look in your docker host’s directory that is provided as your openHAB container’s userdata volume:

[openhab@casabot oh]$ find openhab_userdata/config/ -name 'addons*'

On my test system, that directory is /home/openhab/oh/openhab_userdata:

[openhab@casabot oh]$ cat start-oh

I dont have a addons.config, but I do see a profile.config. Are this/these the offending lines? The one that has ‘mqtt’?


Because I also see this line, which I assume is the needful 2.5 snapshot mqtt binding


So do I just remove all of the .11.0.SNAPSHOT lines?

Update. I found the addons.config file.


Which part should I amend? or do I just delete the whole file?

(J Wee) #70

I removed the line - action
and also the mqtt1 binding. (still dunno how it got there)

This error is gone “[error] [core.karaf.internal.FeatureInstaller] - Failed installing 'openhab-action-nma, openhab-action-mqtt,openhab-binding-mqtt1”

but this error remains on startup

2019-01-21 19:20:33.641 [ERROR] [ntime.internal.engine.RuleEngineImpl] - Error during the execution of startup rule ‘Update Sonoff Status’: Instance is not an MQTTActions class.

Dear guys, @epicurean,

I am following this this topic and I am was also struggling with the same sort of problems, My MQTT connection (server=Mosquitto) is working perfectly from OH2 to my MQTT devices and back. Costed me some (read this as an understatement) effort due to the new set-up and my i.e. sloppy case-sensitive use.

I was also able to remove the recurring error of mqtt1 by deleting the file “/var/lib/openhab2/config/org/openhab/addons.config” (thanks to all/@opus for solving this part). However I still notice on startup the warning “[WARN ] [.MqttBrokerConnectionServiceInstance] - MqttBroker connection configuration faulty: host : You need to provide a hostname/IP!”. Though I do not want to use this broker I think I can solve this problem by configuring in the Paper UI - Configruaration - Services - MQTT MQTT system broker connection(org.eclipse.smarthome.mqttbroker)?

Getting the interaction (this topic) with my Sonoff’s was still on my to do list.

I found this article from @David_Graeff by accident and very helpfull. To get it working I used the “On system start” rule-example monitoring it with MQTTbox. It worked and realised what the problem was in the syntax to restart Sonoff devices. The syntac of @epicurean :

actionsBroker.publishMQTT("mosB", "cmnd/" + device_id + "/STATUS", "2")

is incorrect; the duplicity of the MQTT-broker needs to be removed.

actionsBroker.publishMQTT("cmnd/" + device_id + "/STATUS", "2")

Long story but it also indicates that moving to 2.4/2.5 was a bit of a burden for me in respect of the major MQTT changes. And yes RTFM can be helpful.

A last question i setup the MQTT-broker with a .thing file for both bridge as various things. Reason I find this more handy than the paper UI itself. Not, for sure, in respect of the proper syntax but easier to share/duplicate. The question: is there a way to extract the properties from a paper UI to a text file?
(if it is already there I did not find it yet in the rtFM.

(David Graeff) #72

Not yet. At the moment Paper UI and text files are basically fighting each other and it makes sense to choose one and stay there.

(WJ) #73

No real question, some experience shared

Completely agree I had recent a OH mess-up because I followed the manual of the network binding to the letter and created an <openHAB-conf>/services/network.cfg file (not sure if I also installed the binding itself in paper UI).

Later, for another reason I thought it was wise to do the combination of cleaning the cache and deleting file /var/lib/openhab2/config/org/openhab/addons.config in one go with results all bindings were ‘gone’ and things not working. Oeps. Notice in addons.config that only the Network binding was there. Manage to restore this and OH is now running again but some errors on startup remain.

(SiHui) #74

addons.config is created automatically based on the settings in your addons.cfg and should not be edited.
If you define a binding in addons.cfg it takes precedence over the installed bindings in PaperUI, meaning you either have to define ALL your bindings in addons.cfg OR ALL bindings in PaperUI.

(WJ) #75

Did not change recently anything in addons.cfg; only package and ui is activated here, which explains I lost in the past habpanel because ui info was ‘ui = basic,paper’ I changed this to ‘ui = basic,habpanel,paper’ but based on your answer the better option is to set ui on comment with #ui?

Yesterday I had good experience to re-add the astro.binding to the addons.config file because adding it to the paper ui again gave problems with adding the Astro things with old names (confession: did a forced remove of these things). The Astro binding is working like a charm now again.

(SiHui) #76

Again: don’t edit the config files! If you do not want to use PaperUI, do your complete setup via addons.cfg, stop openHAB, delete the addons.config, then restart openHAB. Based on your settings in the addons.cfg openHAB will recreate the correct addons.config automatically.

I have a DS18B20 sensor on my sonoff RF that reads fine on the sonoff but has this error in OH under MQTT 2.4

Type string : temperature “Temperature” [ stateTopic=“tele/sonoff/powerstrip3/SENSOR”, transformationPattern=“JSONPATH:$.DS18B20.Temperature”]

Number Sonoffps3_Temperature “Powerstrip3 Temperature [%d °C]” (Sonoffps3) { channel=“mqtt:topic:sonoffps3:DS18B20.temperature”}

This is the error:

2019-01-31 15:55:22.544 [ERROR] [el.item.internal.GenericItemProvider] - Binding configuration of type 'channel' of item 'Sonoffps3_Temperature' could not be parsed correctly.

What am I doing wrong?

Configuration of openHAB
(David Graeff) #78

Sigh. It’s not the MQTT bindings fault. You need to read up on the .thing file syntax. I know it is complex and long and tedious, but you decided not use Paper UI.

(Jürgen Baginski) #79

Take a look into PaperUI, under Configuration- Things you will find your thing, click on it and all channels will be shown, under the bold name of the channel the correct syntax for that channel to be used in the items file is shown.
My guess , you omitted the brokername.

(J Wee) #80

Hi David, I am not blaming the binding. I am assuming I mess up somewhere in my configuration of the thing /item file. Which is why I am requesting for insights

Hi Jurgen, you were right on. Somehow I link a wrong item to the temperature channel for that thing.
Thank you very much
