Hi. I know this topic is a few months old now, but I'm wondering if you were able to accomplish what you wanted to do. I have a wifi gateway set up and would like to do something similar but with Home Genie as the broker running on a Raspberry PI. Did you have to modify the MQTT Client code much to fit your needs? I'm new to MySensors, but I've been researching topics as much as possible before I dive into the code. Can you point me to the version of the client code that worked for you? I would appreciate any help or tips as I am eager to set up several sensors around the house and perhaps a relay to control a garage door. Thanks.
