There is a platform, called edge, for developing the equivalent of new DTHs for zigbee devices, Z wave devices, and some LAN devices. Here’s the FAQ on that.
FAQ: I have no idea what Edge is. Is that a new developer tool? (2022)
However, unfortunately it’s not going to help with this specific device, which is called a “OCF “device. As discussed upthread, those work with a different type of integration and there’s not much you can do with those.
