Sonoff New DIY protocol

I need a help!!. I want to integrate my Sonoff Minis to my SmartThing using Http post. I was looking to flash using Tasmota. But now I can DIY without Tasmota on the new protocol, but a I never did it before. Someone already did?; if yes I can use the same Tasmota post to used on that DIY?. Or proceed with using the Sonoff DIY tool with the Tasmota lite bin?

I guess you could modify HTTP switch such as this or this to send HTTP POST to the device API to trigger on/off and more…
