Supported in TASMOTA or later, use this TASMOTA Stock Bin file or Bluetooth enabled until the next standard Tasmota release. Thanks to Cossid for his efforts!

Please note the required SetOption below for correct color order. A user configurable brightness limit of default of 9 is set via the template SM2335 Dat option. This was found to be close to stock as possible. Setting this higher could create power supply issues, excessive heat/fire, LED flame out errors, etc.

Until the next Tasmota standard release, it is necessary to upgrade to or later dev version.

Pop the diffuser off with a spudger. Remove the silicone around the edge of the LED board. Use a spudger again to remove this board as it just using tension connector pins. It might stick a little especially if the bulb is cold. You will see the back of the ESP32-C3 for manual serial flashing if needed. P9 is like GPIO 0 in the ESP32-C3 world, it needs to be grounded at power up to enter into bootloader mode. ESP32 flashing procedures
