I was wondering if there is a python library that would let multiple Pi's talk to 1 main pi over wifi? I was thinking it would be easier to have 2 or 3 pi zero W's spread out for IOT and having 1 main Pi that takes care of users. Or would I need to pickle data and have the pi's constantly check a network folder?
Third vote for MQTT. One advantage of going that route is that it's fully cross-platform and language-agnostic: we use it a lot for mixed networks of Pis and Arduino (ESP8266) controllers/sensors. Izzati looks interesting though - thanks for that, kusti8!
