Last time we saw how to start interpreting whatsapp messages using a simple parser written in Python.
What we did was implementing just a small interaction with our RPi and nothing more. Surely it wasn't a real home automation.
Now it's time to try something closer to that definition. I will keep quite simple, but the concepts are valid for more complex situations too.
Anyway I will just take into account only low-level automation. What I mean is that communication protocols like X10, 1-wire, Modbus, ZigBee and so on will not be used, at least for now.
Maybe in a future I could write a post about these, but do not take this as a fact. It just could happen one day...
