An acquaintance tempted me to try AI. I did. I asked the following question very simply, in my own language: ---------------------------------------------------------- I'm looking for an Arduino program for the D1 Mini ESP8266 that, using the Wi-Fi data from the Pi dongle from HomeWizard (http://192.168.1.206/api/v1/data), outputs the value from "active_power_w":721 serially at a baud rate of 9600, preceded by a -"*". ---------------------------------------------------------- I promptly received this response in Dutch: -------------------------------------------------------------------------- I'm creating an Arduino program for your D1 Mini ESP8266 that reads the active_power_w value from your HomeWizard P1 dongle and outputs it via serial communication. ----------------------------------------------------------------------------- And in less than a minute, I had a program which I loaded into the module, and it promptly delivered what I wanted on its serial output!!! And all I know is how to load it with Arduino. On the one hand, it's incomprehensible and amazing, but on the other, I get a shivering feeling. Is this our future??? regards Hans
