A few months ago I wrote about the process I was using to optimize my website files for SPIFFS prior to upload them to the ESP8266. The goal was to reduce the number and size of the files to help the microcontroller to cope with them in an easier way. Smaller size mean faster downloads and less files mean less concurrency. The process is done using Gulp, a tool to automate processes, and defined in a javascript file....
Firmware over-the-air (OTA) is great. It makes you shiver whenever you throw an update to one of your devices. The ArduinoOTA library for ESP8266 is so easy to use it's almost magic. But once you have several devices deployed you start to think one step further. Here I'm going to talk about two different options: writing an automated deployment script that performs OTA updates or giving your device the ability to call home querying for new updates, downloading them and flash itself into the latest version available....
