Hi all.
I’m looking to automate an evaporative aircon and I’m not sure where to start, the control panel is stupid simple, fan on/off, water pump on/off and then the fan speed.
I will attach a pic of it.
Im in Aus so if anyone has some insight on what I can do that doesn’t break the law that would be good too.
Any ideas? 
Edit: I have a xiaomi temperature sensor that will help me turn this thing on and off.
