Cool!
Have a hard time getting it to work though.
When it finally found my button it got stuck on "connecting" :/

You made a stupid mistake (or maybe the mistake is on me for taking it for granted the buttons would be future proof. Why would anyone make a product that can't be updated? Nobody can be that stupid right?) and wants your first backers to pay again for it. Wonderful.
I don't feel comfortable using something that can't be updated but I don't feel like paying again for the same thing...
