Originally intended to be used with their companion app once flashed using `tuya-convert <https://github.com/ct-Open-Source/tuya-convert>`__ ESPHome generated
firmware can be uploaded allowing you to control the bulbs via Home Assistant.
a. Raspberry Pi 2B/B+ with `USB WiFi Dongle <https://www.raspberrypi.org/products/raspberry-pi-usb-wifi-dongle/>`__.
b. Raspberry Pi 3B/B+.
..note::
As per the `tuya-convert documentation <https://github.com/ct-Open-Source/tuya-convert/blob/master/README.md#requirements>`__:
Any Linux with a Wifi adapter which can act as an Access Point should also work. Please note that we have tested the Raspberry Pi with clean installations
only. If you use your Raspberry Pi for anything else, we recommend using another SD card with a clean installation.
#. A microSD card (minimum 2GB, 8GB+ recommended).
#. Any WiFi device which can connect to the SSID generated by the Raspberry Pi and eventually the flashed Tuya device. **This cannot be an iOS / Apple device.
#. It's recommended to read the documentation provided by the Raspberry Pi Foundation on the best way to flash the OS to the microSD card depending on your
platform - `Installing operating system images <https://www.raspberrypi.org/documentation/installation/installing-images/>`__.
#. After you've flashed the microSD card browse to the "boot" partition and add a blank file called "ssh" **(without any extension)** which will enable the
SSH server upon first boot, extended information on this step can be found `here
#. Plug the microSD card into the Raspberry Pi, connect network cable and power, the Raspberry Pi will start to boot.
2.3 Connecting to the Pi via SSH
********************************
#. Download and install `Putty <https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html>`__.
#. Open Putty.
#. Enter the IP of Raspberry Pi in the box that says "Host Name", leaving the port set to 22 (default for SSH). A list of recommended ways can be found `here
<https://www.raspberrypi.org/documentation/remote-access/ip-address.md>`__, but the easiest is to download and use `Fing <https://www.fing.com/>`__
#. In the "Saved Sessions" input box, name the Raspberry Pi connection and then press "Save".
#. Select your new saved session from the list.
#. Press "Open".
2.4 Configuring the Pi
**********************
#. In the putty window login with the **pi** as the user and **raspberry** for the password.
#. Type ``sudo apt-get update && sudo apt-get dist-upgrade -y`` and wait for the upgrades to install.
#. Type ``sudo apt-get install git`` and wait for it to install.
2.5 Setup and Install tuya-convert
**********************************
#. In the putty window type ``git clone https://github.com/ct-Open-Source/tuya-convert`` press enter and wait while the repository is cloned.
#. Type ``cd tuya-convert`` and press enter.
#. Type ``./install_prereq.sh`` press enter and wait as the script gathers all the required components needed to function.
2.6 Upload ESPHome Firmware using SFTP
**************************************
#. Download `FileZilla <https://filezilla-project.org/download.php?type=client>`__ or `WinSCP <https://winscp.net/eng/index.php>`__ or use your preferred FTP
client.
#. Depending on the program you need to connect to the Pi using the IP address as the hostname and the username and password the same as you used to connect
via SSH and ensure your connection type is set to **SFTP**
#. Browse to ``/root/tuya-convert/files``.
#. Upload your compiled ``firmware.bin`` file to this directory. For command line based installs you can access the file under
``<CONFIG_DIR>/<NODE_NAME>/.pioenvs/<NODE_NAME>/firmware.bin`` alternatively Home Assistant add-on users can download the file directly from the web ui.
#. Connect your alternative WiFi device (non iOS / Apple based) to the ``vtrust-flash`` SSID using ``flashmeifyoucan`` as the password. This is the network
being broadcast by the Pi from the tuya flash script.
#. If you haven't already install your bulb and flip the switch. It should automatically enter pairing mode represented by the bulb flashing on and off. If it
doesn't, switch your bulb, on-off-on-off-on as per the instructions `here
#. Press enter on your putty window to start the flash process and wait. The bulb will stop flashing followed by a large amount of scrolling text, this is the
script backing up the factory shipped firmware.
#. Once the process is complete you can type ``curl http://10.42.42.42/flashURL?url=http://10.42.42.1/files/firmware.bin``
#. The bulb will restart and if everything is working correctly after a few seconds the light should be on.

Thanks to the `existing work <https://github.com/arendst/Sonoff-tasmota/wiki/Mirabella-Genio-Bulb>`__ by
`@so3n <https://github.com/arendst/Sonoff-tasmota/wiki/Mirabella-Genio-Bulb>`__ which these adaptions created by `@cryptelli
<https://community.home-assistant.io/u/cryptelli>`__ and `@bircoe <https://community.home-assistant.io/u/bircoe>`__ are based on.
Kmart also sell a `downlight option <https://www.kmart.com.au/product/mirabella-genio-wi-fi-dimmable-9w-led-downlight/2754331>`__, which works quite well however the PWM method that is used is different to the way the CWWW lights in ESPHome works.
A `project by ssieb <https://github.com/ssieb/custom_components/tree/master/cwww2>`__ resolves this using a custom component.
