Disassembly
Remove the plastic diffuser. Scrape out the thermal glue holding the LED PCB and lift the PCB up to gain access to the ESP32-C3 module with labelled flashing pads.
Flashing
Flash using Tasmota Web Installer and select Tasmota ESP32-C3 option.
For esptool.py download f.e. tasmota32c3.factory.bin and run esptool.py write_flash 0x0 tasmota32c3.factory.bin
To put ESP32-C3 in flash mode GPIO8 needs to be pulled high and GPIO9 pulled low. Some devices have that by default.
