    There is a lot of great retail hardware with ESP chips out in the market. The above site is a collection of ESPHome configurations for a lot of that hardware.

  • Tasmota

    Alternative firmware for ESP8266 with easy configuration using webUI, OTA updates, automation using timers or rules, expandability and entirely local control over MQTT, HTTP, Serial or KNX. Full documentation at

    There's always Tasmota [0]. Personally I prefer ESPHome but recently tossed Tasmota on some OTS Sonoff plug switches. Best part is you can just drop ESPHome firmware in the Tasmota OTA upgrade and switch at any point.

  • Lunar

    Intelligent adaptive brightness for your external monitors

    This project was the best thing I stumbled upon this decade.

    I have used ESPHome to create a wireless ambient light sensor that my Mac app (https://lunar.fyi/#sensor) can use to adapt monitor brightness automatically.

    Even non-technical users are now doing their own sensor with the tutorial I wrote: https://lunar.fyi/sensor

    I also like to use ESPHome for standalone devices like dimmable LED strings and IR remotes, but I always wished there was a simple app to control them. My HomeAssistant dashboard became too complex and slow and is annoying to wait for it when I just want to adjust brightness or volume.

    So I created another app for that called Volum: https://lowtechguys.com/volum

    Below is a demo video of how I use it to control:
