This is a screw-type Edison E27 RGBWW smart-bulb available from Bunnings in Australia and New Xealand
It contains a Tuya TYWE3L module with an ESP8266 chip. Datasheet for the module: https://developer.tuya.com/en/docs/iot/wb2l-datasheet?id=K9duegc9bualu
Here are the current measurements with the stock firmware:
| Colour | Current |
|---|---|
| Whites | 37mA |
| Red | 11mA |
| Green | 12mA |
| Blue | 13mA |
Unfortunately Tuya-cloudcutter doesn't work on this model. You'll need to crack it open and flash it with a USB-TTL adaptor. Heat around where the white plastic meets the diffuse plastic then separate it with a spudger. Then pry up the LED board with a pick.
These are the pins you need to connect to flash the module.
| Wire Color | Function | Location | Notes |
|---|---|---|---|
| Green | TX | First pin on the left | Connect to RX on your USB-TTL Adaptor |
| Blue | RX | Second pin on the left | Connect to TX on your USB-TTL Adaptor |
| White-Orange | GPIO0 | Fifth pin on the left | Connect to GND during flashing |
| White-Blue | 3.3v | Positive side of small capacitor | Connect to 3.3v power supply |
| White-Green | GND | Negative side of large capacitor (underneath) | Connect to GND on power supply and USB-TTL adaptor |
Now visit https://web.esphome.io/ to flash the basic ESPHome firmware. It will reboot when done but won't come back up unless you disconnect GPIO from GND.
