Bump... Just giving the Pi-Py idea a bump... Good to see results of a lot of hard work moving general MQTT concepts across on diverse platforms. Python in a Pi examples and approach would support educational low level electronics + coding lab, workshop and challenges in educational setting areas I work in here in NZ. Either Pi GPIO pins with directly connected boards and or in my case via the diverse array of bus-way connection to other devices. I use low level mirco (picaxe) into serial over short range low tech ASK radio modules to develop sub uAmp idling sensors and creative devices.

Thanks
