KS-501-1 Smart Plug Tasmotize

Hi, I got this smart wifi plug many years ago, and was wondering if it’s possible to flash Tasmota on this? It works fine with the Sonoff integration, however it would be great if it worked over mqtt.

I have the UK equivalent so it’s KS-501-1 running the latest firmware, however I’m unable to get it to work with Sonoff DIY mode, as I’d imagine the device is too old.

Model: KESEN KS-501-1 (Sonoff ITEAD)
Device ID:1000102187
App: eWelink
Firmware: 3.7.6

I prefer to flash using the ota method rather opening the device up if possible.
