Thanx, I have a look of that.

Actually after hours of banging my head against the wall, I managed to get this working, problem is that library uses string(255) variable for incoming messages and domoticzs messages are longer.

Filthy getaway was to parse messages in nodered first and handle rest of the messages in codesys. There should be way to control what domoticz sends in mqtt messages...

Hi,

Here a snippet of my Domoticz Mqtt program.

I use my own Mqtt client.

This project include some controls for Domoticz like Lamp, Dimmer, Lux, Pir, Blinds, ..
These are oop, not really for idiots or newbie but maybe you can use it.

Groetjes Ton.

For being complete newbie to codesys and programming. I just cant get this to work.

I have local broker running in raspberry and it works with examble within library.

But I just cant understand that how I proceed with this.

Waiting for tutorial for idiots...

Im trying to use this library to communicate with domoticz so that I can control my lights from domoticz.

Codesys raspberry controls lights thru beckhoff ethercat io.

Hello,

now all needed Projects are on GitHub. TLS and MQTT are now splittet, i am going on to work on MQTT further.

If you like to ad certificates, you Need to work on CommonTypesAndFunctions, there is an FB IP_CONTROL. This on supports TLS without certificates, take al look on testmqtttls in MQTT.libraray, this works with test.mosquitto.org.

Changing the interface is not longer needed, just extend TLS_CONFIG in CommonTypesAndFunctions.

Hello Stefan,

If TLS is already implemented is it possible to use also own registered cert?

Let me know if you need some help. I also can do some tests.

BR,

Hello Kevin,

TLS implementation is already done, works fine to test.mosquitto.org.

but i still improving the lib to be able to use Topics up to 64kB an Payloads up to 200MB....

i am glad about your offer to help, i am going to think about it.

for this i Need to have a github account, but this shouldn't be the Problem.

Bye

Stefan
