Top 3 C smart-home Projects

  1. Tasmota

    Alternative firmware for ESP8266 and ESP32 based devices 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

    Project mention: Google Killing Nest Thermostats Next Month | news.ycombinator.com | 2025-09-05

    One way is to look for devices that have unofficial firmware available, so you can just overwrite the included software for something more under your control. For example, check out Tasmota, "an open source firmware for Espressif ESP8266, ESP32, ESP32-S or ESP32-C3 chipset based devices": https://tasmota.github.io/docs/

  3. OpenBK7231T_App

    Open source firmware (Tasmota/Esphome replacement) for BK7231T, BK7231N, BL2028N, T34, XR809, W800/W801, W600/W601, BL602, LN882H, Realtek chips and more

    Project mention: More than 135 open hardware devices flashable with your own firmware | news.ycombinator.com | 2026-03-17

    Looks good, but it'll probably take a while until it's anywhere close to the coverage of existing repositories:

    https://templates.blakadder.com/ has almost 3,000 devices flashable onto Tasmota firmware.

    For older Tuya devices there's https://github.com/tuya-cloudcutter/tuya-cloudcutter

    OpenBeken https://github.com/openshwprojects/OpenBK7231T_App covers 800 of the newer generation Tuya devices.

    And there's a large community adapting ESP32 devices onto https://esphome.io/

  4. AmpliPi

    Whole House Audio System 🔊
