Flashing Kogan smart devices w/ Tasmota using tuya-convert

I bought the following devices from Kogan (AU):

KASB10WRGBCCTB22A Kogan SmarterHome 10W RGB+CCT Color & Warm/Cool White Smart Bulb (B22)
KALEPDLRGBCCTA Kogan SmarterHome Smart LED Downlight
KASB10WRGBCCTE27A Kogan SmarterHome 10W RGB+CCT Color & Warm/Cool White Smart Bulb (E27)
KASPEMHUSBA Kogan Smart Plug With Energy Meter (and 2 x USB)
- NOTE: Same device as MS6104 Jaycar Smart Plug WiFi Controlled Main Switch and Energy Monitor with 2 x USB Sockets

I was able to flash them with Tasmota using tuya-convert

Prerequisites

Here's what I used:

Raspberry Pi 3
- connected to my network via Ethernet (because the WiFi gets used to flash the smart device)
- git installed
A first laptop to SSH into the Raspberry Pi 3
A second laptop to connect to the smart device post-flash for it's initial configuration
- You could probably use the first one, but it's fiddly (gotta change the network you're connected to, break the SSH session etc)

Here are the steps I took for each device:

put the device into pairing mode
- for the KASB10WRGBCCTB22A and the KALEPDLRGBCCTA:
  - on, off, on, off, on- it'll go through a blink pattern to show it's going into pairing mode
on the Raspberry Pi 3 (SSH'd in via the first laptop)
- git clone https://github.com/ct-Open-Source/tuya-convert.git
- cd tuya-convert
- sudo ./install_prereq.sh
- sudo systemctl disable mosquitto.service && sudo systemctl stop mosquitto.service
  - this is because install_prereq.sh installed mosquitto but the flash script doesn't like it already running
- sudo ./start_flash.sh
  - connect the second laptop to the "vtrust-flash" SSID as suggested
  - follow the prompts and select the "tasmota" firmware file when prompted

Here are the steps I took after flashing for each device:

on the second laptop
- connect to "tasmota-xxxx" WiFi SSID that appears
- a captive portal will open - if not, navigate to http://192.168.4.1
- configure the WiFi settings for the device
on the first laptop
- for the KASB10WRGBCCTB22A I used this template because this one didn't seem to work
  - NOTE: it's not perfect, I think I'm only getting RGB (I've tried a few other brand RGB+CCT templates and the behaviour is closer to what I'd expect, but the colour warmth setting seems to adjust both warmth and light level)
- for the KALEPDLRGBCCTA I used this template which is the expected one
- for the KASPEMHUSBA I used this template
