Here is some examples / sample code for the RaspberryPI / MQTT / Mosquitto / Ardunio.
SSH to your RaspberryPi, with mosquitto installed, if not already running execute the command “sudo mosquitto” to start the broker.
Now your mosquitto server is running, run the command “mosquitto_sub -d -t HomeZoneCH“, what does this do? it subscribes the RaspberriPi to the topic HomeZoneCH
Open a second ssh session to your Pi and run the command “mosquitto_pub -d -t HomeZoneCH -m “CellarLightOff”” you should see the message below.
On the first SSH session you have open you should see the message below appear!
Now with the code runnning on my Arduino after a reset I receive the following message on the first SSH session.
Now I know this is super simple and your asking yourself what value does this have? it’s just a simple demo of the messaging system… I will be sharing all my final code with Webserver, mosquitto interface etc… as soon as I feel it’s ready. I am moving house soon and will not have much time to focus but I hope to have a good update next month regarding my progress
Have a look at some useful links here, here and here

Hey there, very informative howto… also .
. dont forget to run the mosquito broker .. by running “sudo mosquitto” or you will get the ominous “connection failed” message!
cant wait to see your next posting!

Thanks! Good point I will be sure to update the instructions tonight!
We made the project with its own broker PLC and a bridge between MQTT-S and MQTT systems.
Work on Windows or Linux + Mono.
For Example: Raspberry Pi + ArchLinux + Mono.
As Hardware used: Arduino nano compatible boards plus RFM12 or CC1101 Shield.
