Boot, connect to wifi, server requests in under 1 second with ESP-01

Making a hardware button that connects to wifi and sends a request off to a server is possible using Arduino. Light switches are (almost) immediate – but simple wifi switches easily take 8-10 seconds to connect & switch. How do you get that time down? Here’s my approach. Measure end-to-end - what’s the default time? Is it really that bad, or just sometimes bad? Split into parts Measure the parts Determine which parts should be optimized, and try options Combine the best options Debug why it doesn’t work and try again The computer we’re using to run on is an ESP8266, model ESP-01.
