Tasmota

Tasmota provides an alternative, open‑source firmware for ESP8266 and ESP32 based hardware, enabling users to replace the original firmware with a version that can be configured locally via a web interface, over‑the‑air (OTA) updates, or through serial connection. It offers multiple control channels—including MQTT, HTTP, serial and KNX—so devices can be managed without reliance on cloud services. Automation is supported through built‑in timers, rule engines and scripting capabilities, allowing complex behavior to be defined directly on the device.

The firmware is aimed at hobbyists, makers and integrators who build or retrofit smart‑home and IoT projects, especially those who require full local control and the ability to integrate with existing home‑automation platforms. Its extensibility is demonstrated by support for a wide range of peripherals such as sensors, relays, displays and network extensions, and by the ability to add custom modules or scripts.

Tasmota is distributed under GPL‑3.0, is self‑hostable, and does not require subscriptions or tiered services. Stable releases are provided as pre‑compiled binaries, with development builds available for testing new features. The project includes documentation, a web installer, and a community forum for support and contribution.
