Alternatives to ESPHome
Firmware for DIY smart devices
ESPHome ranks #3 of 8 in Home automation, with an Alt Score of 86. It is licensed under GPL-3.0, free from Free and available on Windows, macOS and Linux. 9 of 10 checklist rows are verified against a public source.
DIY smart-home enthusiasts and integrators who want to build custom devices on ESP32, ESP8266, and similar microcontrollers without writing C++ firmware code.
A YAML-based configuration system that compiles into firmware for supported boards, covering sensors, displays, switches, and other components out of the box. Devices run locally and operate independently of any cloud service. Firmware updates can be pushed over-the-air after the initial flash. Native integration with Home Assistant exposes device entities automatically.
You write a YAML file describing the board and its components (sensors, outputs, etc.), ESPHome compiles it into firmware, and you flash it to the device over USB (or OTA for updates). The device then connects to your network and can be added to Home Assistant, or controlled via ESPHome's own tools.
