I also use node-red-contrib-cast nodes to send audio notifications for the "Frietpan" Switch to my google home speakers.
Now this is working when I turn the "Frietpan" switch ON or OFF, but the 2 delay notifications I have a problem with:

the Switch ON/OFF message is published through the MQTT node: domoticz/out into the node-red flow, but is it also possible to publish a "domoticz" log message to the MQTT node? Then I could use the domoticz "frietpan" delay messages to send the audio messages parallel

using os.execute dzVents can send any MQTT message to any topic. Only thing needed is installed mosquitto on the domoticz system.

Just let me know what you want to send to which topic and when and I will have a look.

var msgFrietpanKlaar = {
    "url": "http://192.168.1.51:1880/frietpan-klaar",
    "contentType": "audio/mp3",
    "volume": 60
}

var msgVolumeBack = {
    "volume": 30
}

if (msg.payload.idx == '283') {
    if (msg.payload.nvalue == '1') {
      
      node.send(msgFrietpanKlaar);
      
      setTimeout(function(){
        node.send(msgVolumeBack);
      }, 7000);
      
     }
}

if (msg.payload.klaarDelay == 'Frietpan is klaar om te frituren') --this is the 15minutes later message

Sorry but no.
I don't use nodered and I have no immediate intention to start with it. Until now I always managed to do the things I need without it.

So the only thing I need to know from you is
What MQTT message do you want to send from the script to which topic and when.

And if applicable: You can also send information to the script with a customEvent embedded in an MQTT message. Send an MQTT
{"command":"customevent", "event":"MyEvent","data":"myData"} and scripts with customEvents = "MyEvent" will trigger.

Yes. If you replace function sendMQTT in the script with this snippet it should do just that.

Code: Select all

        local function sendMQTT(message, topic)
            local MQTTTopic = topic or 'domoticz/out'
            local json = {} json.msg = message
            json = dz.utils.toJSON(json)

        end
