What hardware to use for garage door with 2 reed switches?

Hi,

Right now I use a Shelly 1 with one reed switch to detect closed. I want to add another reed switch to also detect when the garage door is completely open. This way I can detect the status open/closed/opening/closing. Only I don’t seem to have a safe option to fix this to the Shelly one. Are there options to facilitate this setup? To open and close I just have one button (first press open, second press close)

Thnx, but for me it feels too much tinkering. I went for the shelly2pm solution found here: Shelly2.5 Garagedoor opener with 4 states on a Hörmann ProMatic2

I’ll update if I’m successful.
