Your computer is only needed for flashing or compiling; the project is written for PlatformIO.

Alternatively download released binaries and flash them per the installation guide, or compile your own build with PlatformIO.

One caveat for custom builds: ESP8285 based devices only support Flash Mode DOUT, other modes may seem to brick them.

If it is not in the Tasmota Device Templates Repository either, you can create your own Template — the README only asks you not to request new devices unless they require additional code for new features.

Any ESP8266/ESP32 based device can run it, and the community Templates Repository serves as the database of supported devices.
