Hello,
how is it possible to send this command via MQTT?
{"message":"{\"systemcode\":1,\"programcode\":4,\"%s"\:1}","protocol":"rsl366"}
depend on when you wanna send it …

In Rules you can do it this way:
// Connect your MQTT Broker
val mqttActions = getActions("mqtt", "mqtt:broker:77e28eff")
// Publish your message to the MQTT Broker
mqttActions.publishMQTT("path/to/topic", "{\"message\":\"{\"systemcode\":1,\"programcode\":4,\"%s"\:1}\",\"protocol\":\"rsl366\"}")

thank you but it didn’t work 
here are my files:
*.rule
Thing topic RF "RF"{
Channels:
Type switch : Subwooferr "Subwooferrrrr" [ commandTopic="home/OpenMQTTGateway/commands/MQTTtoPilight", on="on", off="off" ]
}
*.item
Switch Subwooferr "Subwoofer NEU" {channel="mqtt:topic:pibroker:RF:Subwooferr"}
*.rule
rule "MQTT Test"
when
Item Subwooferr received update
then
logInfo("FILE", "SUB ACTIVE")
val mqttActions = getActions("mqtt","mqtt:topic:pibroker:RF:Subwooferr")
if(Subwooferr.state == ON){
logInfo("FILE", "SUB ONNNNN")
mqttActions.publishMQTT("home/OpenMQTTGateway/commands/MQTTtoPilight", "{\"message\":\"{\"systemcode\":1,\"programcode\":4,\"%s\":1}\",\"protocol\":\"rsl366\"}")
}else{
logInfo("FILE", "SUB OFFFFF"
}
end
22:24:09.321 [ERROR] [untime.internal.engine.RuleEngineImpl] - Rule 'MQTT Test': Instance is not an MQTTActions class.
have to be on broker not on mqtt topic
thank you.
i change my rule to
rule "MQTT Test"
when
Item test received update
then
logInfo("FILE", "SUB ACTIVE")
val mqttActions = getActions("mqtt","mqtt:topic:pibroker")
if(test.state == ON){
logInfo("FILE", "SUB ONNNNN")
// Publish your message to the MQTT Broker
mqttActions.publishMQTT("home/OpenMQTTGateway/commands/MQTTtoPilight", "{\"message\":\"{\"systemcode\":1,\"programcode\":4,\"%s\":1}\",\"protocol\":\"rsl366\"}")
}else{
logInfo("FILE", "SUB OFFFFF")
}
end
but i got this warning again:
22:46:59.501 [ERROR] [untime.internal.engine.RuleEngineImpl] - Rule 'MQTT Test': Instance is not an MQTTActions class.
hardly believe that this is your broker… should be something like
mqtt:broker:name or mqtt:broker:id (if you made it by generic paperUI)
this is my last change:
rule "MQTT Test"
when
Item test received update
then
logInfo("FILE", "SUB ACTIVE")
val mqttActions = getActions("mqtt","mqtt:broker:pibroker")
if (test.state == ON)
{
mqttActions.publishMQTT("home/OpenMQTTGateway/commands/MQTTtoPilight", "{\"message\":\"{\"systemcode\":1,\"programcode\":4,\"on\":1}\",\"protocol\":\"rsl366\"}")
}
else
{
mqttActions.publishMQTT("home/OpenMQTTGateway/commands/MQTTtoPilight", "{\"message\":\"{\"systemcode\":1,\"programcode\":4,\"off\":1}\",\"protocol\":\"rsl366\"}")
}
end
here is my last Problem.
how can i send
{"message":"{\"systemcode\":1,\"programcode\":4,\"%s"\:1}","protocol":"rsl366"}
and not
{"message":"{"systemcode":1,"programcode":4,"off":1}","protocol":"rsl366"}
so i will send \" not "
{"message":"{\\"systemcode\\":1,\\"programcode\\":4,\\"%s"\\:1}","protocol":"rsl366"}
than i got this warning:
23:41:18.604 [WARN ] [del.core.internal.ModelRepositoryImpl] - Configuration model 'test.rules' has errors, therefore ignoring it: [30,93]: missing ')' at 'systemcode'
[30,112]: no viable alternative at input 'programcode'
[30,132]: no viable alternative at input 'on'
[30,168]: extraneous input ')' expecting '}'
I think you’ll need to use both \\ and \" to send \" , like so \\\"
But why on earth do you want to send messed up JSON?
Thank you.
I will try it.
Because the software of “openmqtt”, need this kind of command.
double escape? not sure, usually you need to escape once and then there goes your chars. But frankly I dunno, sending escaping chars to MQTT which is purely string based sounds to me bit weird.
that example is for cmndline mosquito_pub, have you tried to send it as whole text without escape chars?
not sure what is equivalent of Json object in OH, but when working with ESP’s this kind of code makes json publish into the mqtt
StaticJsonBuffer<300> jsonBuffer;
JsonObject& root = jsonBuffer.createObject();
root["ver"] = swVersion;
root["Uptime"] = String(uptime::getDays()) + "T" + String(uptime::getHours()) + ":" + String(uptime::getMinutes()) + ":" + String(uptime::getSeconds());
root["Temperature"] = decimals(iaqSensor.temperature,1);
root["Humidity"] = decimals(iaqSensor.rawHumidity,1);
root["Pressure"] = decimals((iaqSensor.pressure / 1e2),1);
root["Gas"] = decimals((iaqSensor.gasResistance / 1e3),2);
root["IAQ"] = decimals(iaqSensor.iaqEstimate,1);
root["sIAQ"] = decimals(iaqSensor.staticIaq,1);
root["IAQ_Accuracy"] = iaqSensor.iaqAccuracy;
root["CO2e"] = decimals(iaqSensor.co2Equivalent,3);
root["bVOC"] = decimals(iaqSensor.breathVocEquivalent,3);
root["rawTemperature"] = decimals(iaqSensor.rawTemperature,1);
root["rawHumidity"] = decimals(iaqSensor.humidity,1);
// use it as JSON
char data[300];
root.printTo(data, root.measureLength() + 1);
// mqtt report
client.publish(mqtt_topic, data);
which then produce
home/climate/livingroom {"ver":"0.6","Uptime":"3T11:52:2","Temperature":21.2,"Humidity":45.9,"Pressure":973.4,"Gas":404.47,"IAQ":248.4,"sIAQ":155.5,"IAQ_Accuracy":2,"CO2e":1555.14,"bVOC":3.596,"rawTemperature":21.3,"rawHumidity":46.2}
As you can see, there are no escape characters at all
The “double escape” is really escape-slash escape-quotemark, \\\", because he asked how to send \" in the MQTT payload.
I’m fully with you, it’s a stupid thing to want to do.
ah you probably right I thought it’s escape-slash-quote so after escape all toxic chars are escaped, but you are right that every single one needs to be escaped separately
Thank you for your support.
I will test it and give feedback
thank you four your tipp.
this solution works.
i got this warning:
18:43:19.628 [WARN ] [hab.binding.mqtt.generic.ChannelState] - Command '{"message":"{\"systemcode\":1,\"programcode\":4,\"on\":1}","protocol":"rsl366"}' not supported by type 'OnOffValue': No enum constant org.eclipse.smarthome.core.library.types.OnOffType.{"message":"{\"systemcode\":1,\"programcode\":4,\"on\":1}","protocol":"rsl366"}
do you also know how to change the sich status by receiving data from a RF remote?
most likely your command topic is same with state topic and OH can’t interpret this kind of message to any value ON or OFF
separate your command and status topics
for example like so:
Type switch : eazy "EazyPod" [ stateTopic="garden/service/filters/eazy/stat", commandTopic="garden/service/filters/eazy/cmd", on="ON", off="OFF"]
after i update to openhab 2.5.2 i got this error Message
Rule 'RF Steckerleiste': Instance is not an MQTTActions class.
here is my rule:
rule "RF Steckerleiste"
when
Item Steckerleiste received update
then
if (Steckerleiste.state == ON) {
mqttActions.publishMQTT("home/OpenMQTTGateway/commands/MQTTtoPilight", "{\"message\":\"{\\\"systemcode\\\":1,\\\"programcode\\\":1,\\\"on\\\":1}\",\"protocol\":\"rsl366\"}")
}
else {
mqttActions.publishMQTT("home/OpenMQTTGateway/commands/MQTTtoPilight", "{\"message\":\"{\\\"systemcode\\\":1,\\\"programcode\\\":1,\\\"off\\\":1}\",\"protocol\":\"rsl366\"}")
}
end
Where did you define that object?
