Sending MQTT message from LUA scene

[josjg 5]

I want to send a MQTT message when a Fibaro motion detector detects motion.
Is this possible from a LUA scene?
If not, I want to use a QA. What would be the best way to hook up the QA to motion detected events from my motion detectors?

Sorry for the late reply @frederiksborgvej388, I must have somehow missed your post.

Here is the code for my QA: (left some non-essential and debug parts out)

 

local QoS = {

    AT_MOST_ONCE = 0,

    AT_LEAST_ONCE = 1,

    EXACTLY_ONCE = 2,

}

 

-- IP address of your MQTT broker. I use a Raspberry Pi with Mosquitto broker

local uri = "192.xxx.xxx.xxx"

 

function QuickApp:onInit()

    self:debug("onInit")

    self:connect()

end

 

function QuickApp:connect()

    self.client = mqtt.Client.connect(uri)

end

 

-- Here I use the MQTT message "hc3/motion", but you send any message for the MQTT broker to re-transmit

function QuickApp:motion(deviceId)

    self.client:publish("hc3/motion", tostring(deviceId), {qos = QoS.EXACTLY_ONCE})

end

 

And then here the code for the LUA scene action side where XXX is the ID of the QA created above:

 

fibaro.call(XXX, "motion", sourceTrigger.id)

 

 

Hope this helps you on your way!

You can’t hook or subscribe on events in QA. I am mean what you can’t do in easily only just via looping and calling API for grabbing the current event and via filtering what you want 

about scene - I do not know. IMHO it should works by default just search by forum samples for MQTT IMHO (again) code for QA also implemented for scene. If not?! Yes it’s Fibaro here all is not OK 

so you should separate your task on two tasks 

1st task will be hook event for motion . That’s should work without any issues (God thanks) then you should call method in your QA. Just declare method in your QA and call from scene 

and in QA method send MQTT message to your broker 

easy?! No. That’s fibaro.

Thanks a lot @10der for your answer.
I indeed already used the method you suggest, using two tasks. I have a scene that calls a function of a QA with a parameter (id of the device generating the motion event) and the QA function send the MQTT message...
A pity that it can't be done in an easier/cleaner way, your right!

I am trying to do the same thing now. Would it be possible to show the code you made?
