I’ve just picked up the exact same model yesterday
So far I have connected to it via Tuya. I didn’t bother using the Kogan Smarthome app as I knew that Kogan are Tuya based anyway.
I have it connected to HA using Tuya local via Tuya IoT Platform. So many low cost product use Tuya or a bage engineered version. It is handy to be familar with it)
I am building up a intergration using at the moment and will post back here once Ive made Tuya Local and will post back here once I’ve.
I just have to work out the DPS switch
I have started a blog of my progress so I might have worked it out, If I have It will be on that blog.
