I noticed that to have all the functionality of the device accessible from inside the wall, I would need to pass two CAT5/6 cables through the gasket. One serves ethernet and POE, the other for the lock control, pushbutton, etc. I had quite a time getting two cables through with the outer jacket on, which I thought would be important as it passes to outside. Probably easier if I stripped the jacket back, but would that compromise the seal?
I would suggest either two gaskets or just one larger gasket…
