# SmartClock-OSS: rebuilding SD Pro Smart Weather Clock firmware

> SmartClock-OSS rebuilds firmware for the SD Pro Smart Weather Clock after analysis of its stock image and flash layout. The ESP8266 firmware provides seven clock faces, Open-Meteo weather, a local settings page, and recovery through power cycling; the repository records hardware observations and installation results.
