Pages

Home - basic parameters of the running program, all temperatures, times, steps and progress. Large graph with the loaded program and current temperature progress (kiln and housing). Program control buttons at the bottom depending on program status.
Profiles - add, delete, show and load firing programs.
Logs - list of all program logs. Logs come in pairs: .csv files with all recorded temperatures, and .log files with basic program parameters.
Preferences - view and edit all ESP32Kiln preferences, save them to memory (until reboot) or to disk. All values take effect immediately - even if a program is running - so you can change PID parameters online.
About - basic information about the firmware version and build.
Debug ESP - physical information about the ESP32 board: chip details, memory, SPIFFS usage, etc.
Flash firmware - upload a compiled .bin firmware image or SPIFFS image directly through the browser. See OTA Installation for details.
