# Mirabella Genio Bulb
Mirabella have released a few smart bulbs.
Here is a bit of a guide on how to open them up and then flash with Tasmota.
Here is a bit of a guide on how to flash them with Tasmota.
I am no expert at this but so far it has worked for me.
There are two ways: Over the Air (OTA) or via Serial.
## Flashing Over the Air
Flashing over the air requires running a linux shell script called [tuya-convert](https://github.com/ct-Open-Source/tuya-convert) and hence requires a computer (I used a Raspberry PI 3) with a wifi adaptor that supports AP mode. There are options if you run Windows to use either a virtual machine (it is reported that KALI Linux running on VMWare has worked) or potentially a live usb (I haven't tested it).
Follow this [procedure](https://github.com/ct-Open-Source/tuya-convert#procedure).
I used [tasmota-basic](https://github.com/arendst/Sonoff-Tasmota/releases/download/v6.4.1/sonoff-basic.bin) firmware instead of the custom tasmota-classic firmware included. The benefit of tasmota-basic is the lightbulb will create an access point that you can connect to after it has been flashed for configuration.

## Flashing via Serial
Flashing via Serial requires disassembling the bulb and soldiering wires to the board.
_Note: modifying these bulbs is dangerous if you do not understand what you are doing, please do so at your own risk!_

If you are really good at soldering and have a fine tip on your iron you could possibly skip this step and jump straight to the next one.

Stand the bulb up and de-solder the 2 pads, and straighten the wires to remove the board.
