HomeKit accessing non-smart but automatic blinds through homekit / arduino

[soanis]

What the title says, basically. I have pre-installed automated blinds that work with 2 switches, up and down.
Is it possible to install an arduino or a pi and enable them for homekit?

Has anyone done this or heard of / seen such DIYs?
Whenever I search for it all that comes up are homekit-enabled full packages, or mechanisms to bring non-automatic blinds into homekit.

Thanks a lot in advance!
