The firmware offers a plugin interface to easily extend its functionality. The plugins can be configured via web interface and have access to the network, file system, logging, serial console, I2C bus, GPIO, GPIO expanders, NVS flash, improved and stable internal ADC, RTC memory access, a (more or less) precise RTC during deep sleep, a maximum of 30 days deep sleep, an event/task scheduler, crash logs with stack traces, etc... via API functions. Support for deep sleep, quick boot (~37ms) and WiFi Quick Connect (<230ms) after wake up is also available
1M with most features activated, no OTA updates

SPIFFS has been replaced with LittleFS starting with version 0.0.4.7604
- Visual Studio Code for Windows or Linux
- PlatformIO 6.1.4 (Linux compiles way faster, see compile_time.md)
- WSL2 Virtual Linux and WSL remote extension. Speeds up compiling with many cores by 10-30%

- GCC 10.x
- Modified framework-arduinoespressif8266 v3.1.2-mod
Since this device has not enough memory and CPU power, a SSL webserver is not possible for most environments. To secure a connection, use haproxy with a certificate from https://letsencrypt.org/. Something like *.mydomain.com and redirect all traffic to the devices. Like https://bathroom.mydomain.com to 192.168.0.88, Like https://kitchen.mydomain.com to 192.168.0.77, etc...
