If you feel adventourous, there is a beta version of the upcoming #BTClock v4 firmware: https://web-flasher-v4.btclock.dev/ Based on the new ESP-IDF v6 framework, without Arduino libraries (and no more PlatformIO). It should be more stable because of lower memory consumption (no freezes). Also it has additional fonts because the bitmap fonts are replaced by TTF fonts and integration with more mining pools (ViaBTC, nerdminer pools and Foundry USA). With comprehensive documentation at https://docs.btclock.dev/
