Atlantic Cozytouch / Overkiz

I’ve got a Sauter Asama towel drying heater which supports ‘smart’ control using a gateway device called Atlantic cozy touch (product page, sorry, only French…).

I’ve discovered it communicates on the 868Mhz frequency (using SDRSharp and RTL-USB dongle).

I’m a bit confused as to how I would start to try to control this device using OMG, since everything referencing 868Mhz seems to be about LoRa. I’ve got a LilyGo T-Beam board with a 868/915 chip on it, but also the board page seems to only reference LoRa and not the basic RF communication as it does for 433Mhz
