MQTT integration

[pepijn]

Did you know GPIO is supported native by Domoticz?

[Andrex]

Yes, I see that but my relays are on a separate Pi.
By the way, is there a way to invert the state of the ON/OFF GPIO?
Because my relay board turns ON the relays when the GPIO is 0, so the Domoticz act contrariwise (the switches are all OFF but the relays are all ON).
Thanks!

Domoticz supports a Master/Slave configuration so you can hook multiple Domo's together and have remote nodes.

and for inverting gpio, try: echo 1> /sys/class/gpio/gpioN/active_low

Thanks Nayr, the inversion of the GPIO works!!!

mmm

What can i do more with MQTT
I did make a MQTT broker with mysensors...
Only i do not understand what i can do with MQTT

What are the settings :

And what are the best/beautiful options that in can make, with this...

And it is always so simple what can i do with MQTT and Node red??

[salvacalatayud]

I'm new in all this domoticz things. What I want to know is how to translate the domoticz mqtt in order to manage a modbus plc. What I want is to integrate a plc into domoticz via node red.

Thanks

Hello, I have a question if someone can help me?
Please excuse me for my English, I use Google Translate.

How can I connect this sketch with domoticz and controll?

Thank you!

Can someone tell me
How can I control this in Domoticz?

Default topic is /ZB40_GATEWAY. You can controll it via MQTT with the following topics.

Topic Payload (only one at a time)
/ZB40_GATEWAY/ALL/ up, down, stop
/ZB40_GATEWAY/1/ up, down, stop
/ZB40_GATEWAY/2/ up, down, stop
/ZB40_GATEWAY/3/ up, down, stop

If you have a (mosquitto) MQTT broker installed and working, you can create dummy switches and send commands using mosquitto_pub

Yes I have Mqtt Brocker installed on Raspberry.
and I control my Sonoff relay with it.
Have also created virtual switches, but I do not understand where and how I must insert the lines with Domoticz.
/ZB40_GATEWAY/ALL/ up, down, stop



Could someone describe it to me exactly?

Thank you

Domoticz has two topics domoticz/in and domoticz/out. Please take a look at https://www.domoticz.com/wiki/MQTT for different JSON formats to send/receive

Hello, I have looked here https://www.domoticz.com/wiki/MQTT, but I do not understand how I have to adjust in the sketch?

I now create a Virtuall switch, when I enter the command via browser, I see everything.
But how do I go on?
my MQTT is on 192.168.178.37/ port 1883

Hello guys,

I am playing with Domoticz now for a few days. My biggest problems with Domoticz and MQTT are the way they are using topics and JSON.

1. Domoticz impose the topics domoticz/in and domoticz/out. Why? It gives you not the freedom affined the MQTT standard. Keep the subscripe and publish topics open ( e.i ALF4all/domoticz and/or ALF4all/domoticz/${floorplan name}/${plan name} ), so you are not overwhelmed with messages if you are using a public MQTT-broker (like HiveMQ).

2. JSON is designed to keep messages readable. An object in Domoticz like "idx":1 (device index) is clear, objects as "nvalue" and "svalue" says nothing. Why not using objects as "temperature" and "humidity"? An object as "svalue":"20.5; 33.3; 2" for a Temp + Humidity type sensor is not readable at all. Better in JSON documents is to split up the data in seperate objects like: {"temperature":"20.5", "humidity":"33.3","humidity-status":"2"}.

Even better: {"temperature":"20.5", "humidity":"33.3","humidity-status":"dry"}.

Perhaps it would be nice if this way is also implemented (not diffecult I think) in Domoticz.

b.t.w. As device hardware/firmware I use ESP8266 (thing) -> Arduino IDE -> ArduinoJson.h -> PubSubClient.h -> MQTT -> Domoticz.
