Sounds like there is a market for fire standard approved cat doors! ;)

I loved reading what you are doing with the Pi though.

As you might have guessed, that came to my mind too. Due to the fact that I have worked with a company in the fire damper business, I was contacting them and we were brainstorming about it. The thing is: The market is just non existent. Also fire-protection regulations can be very specific depending on the country you are in. For example, EU ratings are not always recognized here in Switzerland.

Since last week I'm in contact with the manufacturer of the door drive tough because they maybe want to create a product out of it. To be honest I think it would pure marketing and at the moment it is very unlikely to ever hit the market.

A fun dream I've had (context: I've always been confined to apartments) is some sort of cat/pet utopia in a block, so they wouldn't be stuck inside alone. But that wouldn't be feasible since they have to navigate the fire-proof doors between floors...

Unless your cat door goes to market. May luck be on your side :)

(really, don't underestimate niches, you can probably find plenty of places to sell this sort of product...)
