iblinds v3 with homekit bridge

So I have a few sets of iblinds in my home, one v2 and two v3. The v2 seems to work just fine with the homekit bridge integration, but the v3 behaves strangely. I am not able to open and close the blind by toggling it in apple home, but I can control it by changing the “angle” setting.

The v2 shows up as a blinds with a level, but the v3 shows up in home assistant as blind with horizontal angle control. I think that might be why they’re behaving differently.

I think the reason the v3 doesn’t work with the homekit integration might be because it’s missing a bit in the supported_features, 0x4. Is this something I can fix myself? Or should I be contacting iblinds support or filing an issue on the homekit bridge integration?
