Soma Connect integration for Smartshades is almost done. Once this is released and active I will add an update that adds better support for Tilt. It seems HA itself differentiates between tilting and roller shades. I will try to use the tilting support and see how that works. For HomeKit we still use the regular shades integration as their implementation for tilting blinds is very bad. HomeKit requires all blinds to have up/down controls and tilting controls can only be an extra. Also the tilting controls are buried deep inside a device parameter menu so very clumsy for everyday use. I hope this is not the case with HA. And even if it is it will be much easier to solve the issues in HA case.
