Mirabella Genio Bulbs

The Mirabella Genio is a tuya based smart bulb sold by Kmart in Australia.

Originally intended to be used with their companion app once flashed using tuya-convert ESPHome generated firmware can be uploaded allowing you to control the bulbs via Home Assistant.

1. Create the ESPHome Firmware

  1. Refer to either Getting Started with ESPHome or Getting Started with ESPHome through Hass.io before moving onto the next step.
  2. Select a bulb configuration below based on the bulb/s you have and copy all of the text in the code block and paste into your name_of_esphome_configuration.yaml file.
  3. Compile the firmware, again depending on your chosen setup refer to the guides in the first point.

2. Flashing

2.1 Prerequisites

  1. Before you begin you’ll need one of the following linux machines running the latest copy of Raspbian Stretch Lite
  1. Raspberry Pi 2B/B+ with USB WiFi Dongle.
  2. Raspberry Pi 3B/B+.

Note

As per the tuya-convert documentation:

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.

  1. A microSD card (minimum 2GB, 8GB+ recommended).
  2. 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. Android devices will work.

2.2 Installing the OS

  1. 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.
  2. 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.
  3. 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

  1. Download and install Putty.
  2. Open Putty.
  3. 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, but the easiest is to download and use Fing (Android / iOS).
  4. In the “Saved Sessions” input box, name the Raspberry Pi connection and then press “Save”.
  5. Select your new saved session from the list.
  6. Press “Open”.

2.4 Configuring the Pi

  1. In the putty window login with the pi as the user and raspberry for the password.
  2. Type sudo apt-get update && sudo apt-get dist-upgrade -y and wait for the upgrades to install.
  3. Type sudo apt-get install git and wait for it to install.

2.5 Setup and Install tuya-convert

  1. In the putty window type git clone https://github.com/ct-Open-Source/tuya-convert press enter and wait while the repository is cloned.
  2. Type cd tuya-convert and press enter.
  3. 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

  1. Download FileZilla or WinSCP or use your preferred FTP client.
  2. 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
  3. Browse to /root/tuya-convert/files.
  4. 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 Hass.io users can download the file directly from the web ui.

2.7 Use tuya-convert to install ESPHome Firmware

  1. Type ./start_flash.sh
  2. Type yes to accept the warning.
  3. 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.
  4. 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.
  5. 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.
  6. Once the process is complete you can type curl http://10.42.42.42/flashURL?url=http://10.42.42.1/files/firmware.bin
  7. The bulb will restart and if everything is working correctly after a few seconds the light should be on.

3. Bulb Configurations

Thanks to the existing work by @so3n which these adaptions created by @cryptelli and @bircoe are based on.

3.1 Monochromatic Bulbs

So the brightness of the bulb can be controlled we use the esp8266_pwm output component connected to the light component using the id configuration variable output_component1.

esphome:
  name: mirabella_genio_cw_1
  platform: ESP8266
  board: esp01_1m

wifi:
  ssid: 'WIFI'
  password: 'WIFIPASS'

logger:

api:

ota:

light:
  - platform: monochromatic
    name: "Mirabella Genio Smart Bulb"
    id: light
    output: output_component1

    # Ensure the light turns on by default if the physical switch is actuated.
    restore_mode: ALWAYS_ON

output:
  - platform: esp8266_pwm
    id: output_component1
    pin: GPIO13

3.2 Cold + Warm White Bulbs

esphome:
  name: mirabella_genio_cwww_1
