Open-source firmware for ESP-based smart home devices

tasmota.github.io/docs ↗

Tasmota's release train is a hardware-support treadmill — new silicon, new sensors, every two months

iot-firmwareesp32sensor-supportdevice-drivershome-automation
◆Current state
Tasmota ships a named minor roughly every two months, and each one is a long list of newly supported devices: CO2 and air-quality sensors, RTCs, I/O expanders, display controllers, energy monitors and board templates. The platform work underneath tracks Espressif's silicon closely, with ESP32-P4 and ESP32-C5 support arriving and an ARCH template key now covering eleven ESP32 variants.
◆Where it's heading
The direction is breadth, not depth — Tasmota's value is that whatever ESP-based device someone buys, a driver already exists. The infrastructure work serves that goal: the redesigned ESP8266 I2C driver enabling a second bus, multi-bus support for existing expanders, and an Extension Manager replacing the older partition tooling all exist to fit more drivers onto constrained hardware.
◆Prediction
Expect the next minor to follow the same shape — another codenamed release adding sensor and board support, tracking whichever ESP32 variants Espressif ships next.

◆Recent moves

  1. 1mo ago

    Tasmota v15.5.0 Sylvan

    Raises camera max resolution from 14 to 24 steps, adds fixed access-point selection by BSSID, Modbus relay and RX-enable GPIO support, and M5Stack Atom S3R drivers. Also allows multi-byte characters such as emoji in light toggle buttons.

    Tasmota v15.4.0 Sybil

    Introduces an ARCH key in device templates spanning eleven ESP variants, and redesigns the ESP8266 I2C Wire driver to support a second bus with PCA9685 and PCF8574 following. Template portability and bus capacity are the recurring constraints this release attacks.

    Tasmota v15.3.0 Susan

    Adds I/O expander, rotary encoder, RTC, air quality and FRAM support, plus SPI bus2 for Ethernet and SD card on ESP32 and Berry directory listing inside .tapp archives. Both platform toolchains were bumped.

    Tasmota v15.2.0 Stephan

    Brings ESP32-P4 rev.3 support, analogue gauges, a solar charger energy monitor, DALI DT8 RGBWAF colour control through Tasmota's light system, and ECDSA enabled by default for TLS on ESP8266. The DALI work extends reach into commercial lighting.

    Tasmota v15.1.0 Stella

    Adds support for two new Espressif parts — ESP32-P4 and ESP32-C5 — plus an ESP32 Extension Manager replacing the Partition Wizard, hardware SHA acceleration for BearSSL, and LoRaWAN decoder commands. Tracking new silicon this quickly is what keeps the firmware default on new boards.

    Tasmota v15.0.1 Sharon

    A patch fixing three Berry and LVGL regressions introduced by the 15.0.0 release, including one from the LVGL 9.3.0 upgrade. The entry republishes the full 15.0.0 changelog alongside its own three fixes.
