Is MQTT action exists?

martiniman · December 15, 2015, 9:42pm

I want it

There is no MQTT action.

But what would you want to do with an action that you cannot do with a String Item bound to a an MQTT topic and publishing a message using postUpdate?

For example:

Item:

String N_D_Update { mqtt=">[mosquitto:entry_sensors/getUpdate:state:*:default]" }

Rule Code:

N_D_Update.postUpdate("update")

The above rule code will publish the word “update” to the topic entry_sensors/getUpdate. I use it to request the current status of some sensors.

There is, but you need to be running 1.8.

See: Actions · openhab/openhab1-addons Wiki · GitHub

rlkoshak · December 15, 2015, 10:59pm

Presumably this would also require an MQTT actions jar file installed, correct?

Udo_Hartmann · December 15, 2015, 11:06pm

Should be found here (in addons.zip)

Pretty sure this link is deprecated. MQTT action is part of mqtt2 Binding.

Is there a way to install 1.8 from apt-get? I also would like this feature but would really like to keep everything under the package manager.

robconnolly · December 16, 2015, 3:26am

Not that I’m aware of. I’m running a couple of 1.8-SNAPSHOT addons that I installed manually to my 1.7.1 instance - after removing the version installed by Apt. This works fine, I just won’t get any updates for those addons via Apt.

Joshua_Gilman · December 16, 2015, 3:52am

Interesting that 1.8 wouldn’t be under the testing/unstable branch.

watou · December 16, 2015, 11:42am

The distribution packaging mechanism does not currently support “unstable”. It would be nice to have!

martiniman · December 16, 2015, 1:12pm

There is no mqtt action bundle in this package.

watou · December 16, 2015, 1:14pm

I will submit a pull request to include it in the distribution. Whoops!

martiniman · December 16, 2015, 1:16pm

Thanks!

watou · December 16, 2015, 1:27pm

The JAR should be in addons.zip from the next nightly build. In the meantime, here is one.

Udo_Hartmann · December 16, 2015, 6:17pm

Strange, build-list said Build-Duration for MQTT-action was 1.2secs… direct Link: https://openhab.ci.cloudbees.com/job/openHAB/lastStableBuild/org.openhab.action$org.openhab.action.mqtt/artifact/org.openhab.action/org.openhab.action.mqtt/1.8.0-SNAPSHOT/org.openhab.action.mqtt-1.8.0-SNAPSHOT.jar

hakan · December 16, 2015, 6:34pm

Yes, the jar was being built but not included in the final deliverable. Tha’s what @watou fixed.

Expect the new functionality on tonights Jenkins build.

How to post a retained message to topic?

watou · December 19, 2015, 3:59am

Since the action uses the same underlying MqttService as the binding, you would set retain to true in openhab.cfg as documented here. I just updated the Actions wiki page with this info as well.

martiniman · January 4, 2016, 10:21am

I try to create 2 connections to mqtt retained and not, but it not works for me.
Please view my settings, is it right?
openhab.cfg: mqtt:wb.url=tcp://192.168.1.4:1883 mqtt:wb.clientId=openhab mqtt-eventbus:broker=wb mqtt:wb.retain=false

mqtt:wbr.url=tcp://192.168.1.4:1883
mqtt:wbr.clientId=openhab2
mqtt-eventbus:broker=wbr
mqtt:wbr.retain=true

watou · January 4, 2016, 10:45am

I see you are defining the mqtt-eventbus:broker config value twice, once as wb and again as wbr.

martiniman · January 4, 2016, 11:48am

mqtt-eventbus:broker should be only one for same server?
And if i use another mqtt server 192.168.1.5 - should i define eventbus:broker for it?
